SAFETY INFORMATION

GENERATOR SAFETY WARNINGS

DANGER! CARBON MONOXIDE

Using a generator indoors CAN KILL YOU IN MINUTES. Generator exhaust contains carbon monoxide (CO). This

is a poison gas you cannot see or smell. If you can smell the generator exhaust, you are breathing CO. But even

if you cannot smell the exhaust, you could be breathing CO.

NEVER use a generator inside homes, garages, crawl spaces, or other partially enclosed areas. Deadly levels

of carbon monoxide can build up in these areas. Using a fan or opening windows and doors does NOT supply

enough fresh air. ONLY use a generator outside and far away from windows, doors, and vents. These openings

can pull in generator exhaust.

Even if you use a generator correctly, CO may leak into the home. ALWAYS use a battery-powered or battery-

backup CO alarm in the home. If you start to feel sick, dizzy, or weak after the generator has been running, move

to fresh air RIGHT AWAY. See a doctor. You may have carbon monoxide poisoning.

WARNING! RISK OF EXPLOSION. HIGHLY FLAMMABLE: This generator may emit highly ﬂammable and

explosive gasoline vapors, which can cause severe burns or even death, if ignited. A nearby open ﬂame can lead

to explosion even if not directly in contact with gasoline.

• Do not operate near open ﬂame, heat, or any other ignition source. Do not smoke near the generator.

• Always operate on a ﬁrm, level surface.

• Always turn generator off before refueling. Allow generator to cool for at least 2 minutes before removing

fuel cap. Loosen cap slowly to relieve pressure in tank.

• Do not overﬁll fuel tank. Gasoline may expand during operation. Do not ﬁll to the top of the tank. Allow for

expansion. Always check for spilled fuel before operating.

• If fuel spills, move the generator at least 30 feet away from the spill and wipe clean any spilled fuel before

starting the engine.

• Empty fuel tank before storing or transporting the generator.

WARNING! If this generator is used as a supply for a building’s wiring system, the generator must be in-

stalled by a qualiﬁed electrician and connected to a transfer switch as a separately derived system in accordance

with all applicable laws and electrical codes and the National Electrical Code, NFPA 70. The generator shall be

connected to a transfer switch that switches all conductors excluding the equipment grounding conductor. The

frame of the generator shall be connected to an approved grounding electrode.

STEP 1 - ADD / CHECK OIL

The generator is shipped without oil. User must add the proper amount of oil before operating the generator for the

ﬁrst time. The oil capacity of the engine crankcase is 30.4 ﬂ. oz. (0.90 L).

Instructions continue on the next page.

GENERATOR PREPARATION

Lower Limit

Upper Limit

To add oil, follow these steps:

1. Place the generator on a level surface. Make sure the en-

gine is off before adding or checking oil.

CAUTION: Keep the generator level! Tilting the generator

to assist in ﬁlling will cause oil to ﬂow into the wrong

areas of the engine and cause damage.

2. Turn the dipstick (Fig. 1 - 1) counterclockwise until it is

unscrewed from the engine.

3. Using an oil funnel or appropriate dispenser, slowly add

oil into the oil ﬁll, being careful not to overﬁll the unit. Fill the

crankcase until you can see the oil coming halfway up the oil

ﬁll threads (Fig. 2).

4. Reinstall the oil dipstick and ﬁrmly tighten it. Wipe clean

any spilled oil.

STEP 1 - ADD / CHECK OIL (CONTINUED)

For subsequent operation, the oil level should be checked

before each use, or after every 8 hours of operation. The

generator is equipped with a low-oil sensor and will not start

without a sufﬁcient amount of oil.

To check oil level (before every subsequent start):

1. Place the generator on a level surface. Make sure the en-

gine is off before adding or checking oil.

2. Remove and wipe the dipstick with a clean rag.

3. Insert the dipstick into the oil ﬁll without screwing it in.

Remove the dipstick to check the oil mark (Fig. 3).

If the oil mark covers less than one half of the dipstick, slow-

ly add oil until the oil mark reaches to the top of the dipstick.

4. Wipe clean any oil leaks and ﬁrmly tighten the dipstick.

OIL LEVEL SHUTDOWN

To protect the unit from damage, the generator is equipped

with a low-oil-pressure shutoff that will automatically stop

the engine when the oil level is too low. The low oil alert light

(Fig. 4) will turn ON to remind you that the engine oil level is

low and needs to be reﬁlled.

TIP: Your WEN generator is compatible with the WEN GNA273 Magnetic Oil Dipstick (not included), available for

purchase at wenproducts.com. The dipstick’s industrial-strength magnetic tip will collect metal shavings from your

generator’s oil compartment to help preserve the engine and extend your generator’s lifespan.

GENERATOR PREPARATION

WARNING! RISK OF EXPLOSION. HIGHLY FLAMMABLE: This generator may emit highly ﬂammable and

explosive gasoline vapors, which can cause severe burns or even death, if ignited. A nearby open ﬂame can lead

to explosion even if not directly in contact with gasoline.

• Do not operate near open ﬂame, heat, or any other ignition source. Do not smoke near the generator.

• Always operate on a ﬁrm, level surface.

• Always turn generator off before refueling. Allow generator to cool for at least 2 minutes before removing

fuel cap. Loosen cap slowly to relieve pressure in tank.

• Do not overﬁll fuel tank. Gasoline may expand during operation. Do not ﬁll to the top of the tank. Allow for

expansion. Always check for spilled fuel before operating.

• If fuel spills, move the generator at least 30 feet away from the spill and wipe clean any spilled fuel before

starting the engine.

• Empty fuel tank before storing or transporting the generator.

STEP 2 - ADD / CHECK FUEL

FUEL OPTION A: GASOLINE

Use ONLY fresh (within 30 days from purchase), lead-free gasoline with a minimum of 87 octane rating. The genera-

tor performs best with ethanol-free gasoline. DO NOT use gasoline with over 10% ethanol. The capacity of the fuel

tank is 6.70 US gallons (25.40 L). Do not mix oil with gasoline.

To add gasoline:

1. Make sure the generator is shut OFF and on a level surface.

Unscrew the fuel cap (Fig. 5 - 1) and set it aside. The fuel cap

may be tight and hard to unscrew.

2. Slowly add unleaded gasoline to the fuel tank. Be careful

not to overﬁll.

NOTE: Do not ﬁll the fuel tank to the very top. If you do so,

gasoline will expand and spill during use, even with the fuel

cap in place.

3. Reinstall fuel cap and wipe clean any spilled gasoline with

a dry cloth.

To check fuel level:

Check the fuel gauge (Fig. 5 - 2) on top of the fuel tank. If

the fuel level is low, reﬁll the fuel tank before starting your

generator for the next time.

IMPORTANT:

• Avoid getting dirt or water into the fuel tank.

• Keep gasoline away from sparks, open ﬂames,

pilot lights, heat, and other sources of ignition.

• Gasoline can age in the tank and make starting

difﬁcult. Never store the generator for more

than 2 months with fuel in the tank.

• Never use an oil/gasoline mixture.

• Never use old gasoline.

Fig. 5

GENERATOR PREPARATION

FUEL OPTION B: LIQUID PETROLEUM GAS (LPG)

DANGER! Explosion and ﬁre. LP vapors are extremely ﬂammable and explosive. Do not use or store LP

cylinder in a building, garage or enclosed area. Failure to do so will result in death or serious injury.

WARNING! Explosion and ﬁre. The cylinder valve should be turned OFF (closed) when generator is not in

use. Failure to do so could result in death or serious injury.

• Always keep the LPG cylinder in an upright position.

• When transporting and storing, keep cylinder secured in an upright position with cylinder valve turned off. Keep

cylinders ventilated and away from heat when in a vehicle.

• Liquid Petroleum Gas (LPG) is highly ﬂammable and explosive. Flammable gas under pressure can cause a ﬁre

or explosion if ignited.

• In any petroleum gas ﬁre, ﬂames should not be extinguished unless the fuel supply valve is turned OFF. If a ﬁre

is extinguished and a supply of fuel is not turned OFF, an explosion hazard could be created.

• RISK OF BURNS. Contact with liquid contents of cylinder will cause freeze burns to the skin. If liquid contents

contacts skin or eyes, seek immediate medical attention.

• When exchanging LPG cylinders, be sure the cylinder valve is of the same type.

FUEL OPTION B: LIQUID PETROLEUM GAS (LPG) (CONT.)

• You can use LPG tanks with Type 1, right hand Acme threads with this generator. Verify that the qualiﬁcation date

on tank has not expired. Do not use rusted or damaged cylinders.

• All new cylinders must be purged of air and moisture prior to ﬁlling. Used cylinders that have not been plugged or

kept closed must also be purged.

• The purging process should be done by the propane gas supplier. (Cylinders from an exchange supplier should

have been purged and properly ﬁlled by supplier).

To connect your generator to an LPG cylinder:

1. Take off the safety caps from the cylinder valve, generator-mounted

regulator, and regulator connecting hose ends.

2. With the LPG tank closed, attach the ﬁrst-stage regulator to the valve.

Turn the regulator’s plastic coupling right (clockwise) to tighten the as-

sembly onto the LPG tank (Fig. 6).

3. Connect the other end of the hose to the generator’s onboard regula-

tor (Fig. 7 - 1) with a 3/4 in. (19mm) wrench (not supplied).

4. Turn the LPG tank valve ON and check for leaks by spraying soapy

water to check the connections. If bubbles appear, become larger in size,

or increase in number, a leak exists. This must be corrected before using

the generator. Contact your local Independent Authorized Service Dealer

(IASD) for assistance.

NOTE: You can use Teﬂon (or other tape) to help seal the connection

between the regulator hose and the generator.

CAUTION! Always position the LPG cylinder so the connection

between the valve and regulator won’t cause sharp bends or kinks in

GENERATOR PREPARATION

ABOUT THE BATTERY

1. The lithium-ion battery supplied with your generator

is only partially charged, in order to maximize its service

life. The battery may not have enough charge to start the

engine during its ﬁrst use. If this is the case, connect the

battery according to the instructions below, and start the

generator using the recoil starter, according to the in-

structions below. The battery will receive charge when

the generator is running.

2. Lithium-ion batteries are subject to a natural aging

process. The battery must be replaced at the latest when

its capacity falls to just 80% of its capacity when new.

Weakened cells in an aged battery are no longer capable

of meeting the high power requirements needed for the

proper operation of your generator, and therefore pose a

safety risk.

3. DO NOT INCINERATE BATTERY. Do not throw the bat-

tery into an open ﬁre as this poses a risk of explosion. Do

not ignite the battery or expose it to ﬁre.

4. AVOID DAMAGE AND SHOCKS. Immediately replace

batteries that have been dropped from a height of more

than one meter (3 feet) or those that have been exposed

to violent shocks, even if the housing of the battery ap-

pears to be undamaged. The battery cells inside the bat-

tery may have suffered serious damage. In such instanc-

es, please read the waste disposal information on p. 31

for proper battery disposal.

STEP 3 - CONNECTING THE BATTERY

WARNING! Use only genuine WEN batteries with your generator (part no. DF8000X-065). Use of other bat-

teries may induce premature product failure and could pose a safety risk.

To connect the battery:

1. Connect the two ends of the quick connector on the

battery (Fig. 8 - 1) to connect the battery to the genera-

tor's system. Make sure the battery is secured to the

generator frame by the battery strap.

NOTE: The generator can be run with the battery dis-

connected or with no charge using the recoil starter and

gasoline.

IMPORTANT: If you do not plan to use the generator for

an extended period of time, we recommend DISCON-

NECTING the quick-connector. This will protect the bat-

tery from losing its charge. After disconnecting the quick-

connector, cover the ends of the cable with an insulator

such as electrical tape. Alternatively, you can use a trickle

charger (not included) to maintain battery charge.

Fig. 8

5. DO NOT CRUSH, DROP OR DAMAGE BATTERY. Do

not use the battery if it has sustained a sharp blow, been

dropped, run over or has been damaged in any way (e.g.

pierced with a nail, hit with a hammer, stepped on, etc.).

6. DO NOT DISASSEMBLE. Incorrect reassembly may

pose a serious risk of electric shock, ﬁre or exposure

to toxic battery chemicals. If the battery or charger are

damaged, call WEN customer service at 1-847-429-9263

for assistance.

7. DO NOT SHORT CIRCUIT. Batteries will short circuit

if a metal object makes a connection between the posi-

tive and negative contacts on the battery. Do not place

the battery near anything that may cause a short circuit,

such as paper clips, coins, keys, screws, nails and other

metallic objects. A short-circuited battery poses a risk of

ﬁre and severe personal injury.

NOTE: The safe temperature range for charging the bat-

tery is 25°F – 104°F. The generator is shipped with the

lithium-ion battery’s negative (-) terminal disconnected

to maximize safety. To start the generator using electric

start, the battery must be connected.

GENERATOR PREPARATION

STEP 4 - GROUND THE GENERATOR

To reduce the risk of electric shock and to maximize safety, the genera-

tor should be properly grounded.

Ground the generator by tightening the grounding nut (Fig. 9 - 1) on

the front control panel against a grounding wire. A generally acceptable

grounding wire is a No. 12 AWG (American Wire Gauge) stranded cop-

per wire.

This grounding wire should be connected at the other end to a copper,

brass, or steel grounding rod that is driven into the earth. Wire and

grounding rods are not included with the generator.

NOTE: Grounding codes can vary by location. Contact a local electrician

to check the area codes.

WARNING! Failure to properly ground the generator increases your risk of electric shock.

HIGH ALTITUDE OPERATION ABOVE 3000 FEET

The fuel system on this generator may be affected by operation at high altitudes. Proper operation can be ensured by

installing an altitude kit at altitudes higher than 3000 feet above sea level. At elevations above 8000 feet, the engine

may experience a decrease in performance, even with the proper altitude kit. Operating this generator without said

kit may increase the engine’s emissions and decrease both fuel economy and performance.

You can order the kit at wenproducts.com by searching part DF8000X-HA. There are two kits - one for altitudes

between 3000 and 6000 feet (part no. DF8000X-HA36), and the other for altitudes from 6000 to 8000 feet (part no.

DF8000X-HA68). This kit should be installed by a qualiﬁed mechanic. Refer to the instructions included with your

altitude kit for more information about installation.

NOTE: The high altitude kit must be installed for operation above 3000 feet.

WARNING! To prevent serious injury from ﬁre, follow the kit installation procedures in a well-ventilated

area away from ignition sources. If the engine is hot from use, shut the engine off and wait for it to cool before

proceeding. Do not smoke near the generator. Warranty will be void if adjustments are not made for high altitude

use.

CAUTION: Engines with the high-altitude kit installed operated at lower altitudes could cause severe engine dam-

age and affect emissions compliance. Be sure to uninstall the high altitude kit when operating at altitudes below

3000 feet.

After completing the above preparation, the generator is ready to be started.

Fig. 9

CAUTION! Disconnect all electrical loads from the generator before attempting to start.

Before starting the generator, make sure you have read and performed the steps in the “Generator Preparation”

section of this manual. If you are unsure about how to perform any of the steps in this manual please call 1-847-

429-9263 M-F 8-5 CST for customer service.

To maximize safety, ALWAYS ground the generator before using it. See section “Ground the Generator”.

Use a ground fault circuit interrupter (GFCI) in highly conductive areas such as metal decking or steel work. GFCIs

are available in-line with some extension cords.

STARTING YOUR GENERATOR

DANGER! CARBON MONOXIDE

Using a generator indoors CAN KILL YOU IN MINUTES. Generator exhaust contains carbon monoxide (CO). This

is a poison gas you cannot see or smell. If you can smell the generator exhaust, you are breathing CO. But even

if you cannot smell the exhaust, you could be breathing CO.

NEVER use a generator inside homes, garages, crawl spaces, or other partially enclosed areas. Deadly levels

of carbon monoxide can build up in these areas. Using a fan or opening windows and doors does NOT supply

enough fresh air. ONLY use a generator outside and far away from windows, doors, and vents. These openings

can pull in generator exhaust.

Even if you use a generator correctly, CO may leak into the home. ALWAYS use a battery-powered or battery-

backup CO alarm in the home. If you start to feel sick, dizzy, or weak after the generator has been running, move

to fresh air RIGHT AWAY. See a doctor. You may have carbon monoxide poisoning.

WARNING! The exhaust from this product contains chemicals known to the State of California to cause

cancer, birth defects, or other reproductive harm.

WARNING! Do not operate generator near open ﬂame or ﬂammable materials This generator may emit

highly ﬂammable and explosive gasoline vapors, which can cause severe burns or even death if ignited. A

nearby open ﬂame can lead to explosion even if it isn’t directly in contact with gasoline. Do not smoke near the

generator.

WARNING! This generator produces powerful voltage, which can result in electrocution.

WARNING! Do not use in rainy or wet conditions. Do not touch bare wires or receptacles (outlets). Do not

allow children or non-qualiﬁed persons to operate.

WARNING! Generator should only be connected to electrical devices, either directly or with an extension

cord. NEVER connect to a building electrical system without a qualiﬁed electrician and connected to a transfer

switch as a separately derived system. Such connections must comply with local electrical laws and codes.

Failure to comply can create a back-feed, which may result in serious injury or death to utility workers.

BEFORE STARTING THE GENERATOR

1. Verify that the generator is outside on a dry, level surface with at least two feet of clearance on all sides.

2. To maximize safety, check that the generator is properly grounded (see "GROUND THE GENERATOR").

3. Check that there is a sufﬁcient level of oil in the crankcase. Add oil if necessary (see "ADD / CHECK OIL").

4. Make sure that there is enough gasoline in the fuel tank (or LPG in the LPG cylinder). Add fuel if necessary (see

"ADD / CHECK FUEL").

5. Make sure that the battery is connected (see "CONNECTING THE BATTERY").

6. Make sure all electrical devices are unplugged from the generator during ignition otherwise it will be difﬁcult for

the engine to start.

STARTING YOUR GENERATOR

STARTING THE GENERATOR

1. To use gasoline, turn the fuel valve (Fig. 10 - 1) to the ON posi-

tion. To use LPG, make sure all of the LPG connectors and hoses

are well connected and sealed. Turn the fuel valve to the OFF posi-

tion, then open the LPG tank valve.

2a. Turn the fuel selector switch on the panel to the appropriate

fuel (gasoline or LPG).

2b. If using LPG, prime the engine. To do this, move the choke

lever (Fig. 11 - 1) to the CLOSED position, then gently pull the

3a. If using gasoline, turn the choke lever (Fig. 11 - 1) to the

CLOSED position.

3b. If using LPG, turn the choke lever (Fig. 11 - 1) to the OPEN

position.

Option A: Electric Start

4. Push the engine switch (Fig. 12) to the START position and

hold for 2-3 seconds until the engine starts, then release.

NOTE: The battery is shipped partially charged, in order to

maximize its service life, and may not have enough charge

to start the engine during the ﬁrst use of the generator. If you

have trouble starting the generator the ﬁrst time using electric

start, use the pull start option and allow the generator to run

for a few hours to charge the battery.

Option B: Pull Start

4a. Push the engine switch (Fig. 12) to the ON position.

4b. Place one hand on the generator to hold it in place, and

pull on the recoil starter handle (Fig. 11 - 2) slowly until a

slight resistance is felt. Then pull quickly to start the engine.

Return cord gently into the machine. Never allow the cord to

snap back.

NOTE: If engine fails to start, repeat step 3.

5. Once the engine starts, turn the choke lever to OPEN.

6. Allow the generator to run for several minutes before attempt-

ing to connect any electrical devices. This allows the generator to

stabilize its speed and temperature.

ENGINE BREAK-IN PROCEDURE

The procedure below should be followed when

you receive your generator in order to prolong

the engine's service life. This procedure helps

to seat the piston rings properly in the cylinder,

and will reduce overall wear on the engine.

For the ﬁrst 8 hours of operation, vary the load,

but keep it at or below 50% of the generator's

rated wattage, if possible. If your generator is

equipped with an Eco-mode switch (only ap-

plicable for certain inverter generators), engage

Eco-mode periodically during the ﬁrst 8 hours.

After the ﬁrst 8 hours, change the oil, then

change it again after the ﬁrst 25 hours. You may

run the generator at full load after the 8-hour

oil change. Refer to the Recommended Main-

tenance Schedule in Table 4 for the full mainte-

nance schedule.

Table 1 - How to Calculate Wattages

Generator

Wattage

Capacity

Generator Running (Rated) Watts Generator Starting (Surge) Watts

Gasoline: 6500W Gasoline: 8000W

LPG: 5850W LPG: 7200W

What this means:

The generator can produce a maximum of

6500W/5850W on a continuous basis to sup-

ply ongoing power to your electronic devices.

NOTE: Also check the rated amperage for each

outlet and make sure not to overload the indi-

vidual outlets.

What this means:

Some devices such as box fans require short

bursts of extra power in addition to the rated

wattage listed by the device to start their mo-

tors.

The generator can produce a maximum watt-

age of 8000W/7200W for a short period of

time (seconds) to cover the extra starting

power required by your electronic devices.

Electronic

Device Wattage

Calculation

Find the wattage information of each device you plan to connect. The information should be

listed on the device or in its instruction manual.

The wattage can be calculated using this equation:

Watts = Volts x Amperes

To calculate the total running watts of your

devices:

+ Add up the running wattages of all the

device(s) you plan to connect

= The total running wattage

This wattage should NOT exceed the running

wattage of 6500W/5850W.

It is recommended to maintain a load at or

below 5850W/5265W (90% of the rated

output) to ensure steady voltage output and

to prolong the generator’s lifespan.

To calculate the total starting watts of your

devices:

+ Add up the total running wattage of all the

device(s) you plan to connect

+ Add the single highest ADDITIONAL start-

ing wattage out of the device(s) you plan to

connect

= The total surge (starting) wattage

This wattage should NOT exceed the starting

wattage of 8000W/7200W.

If any of either of the total calculated running watts or starting watts is higher than the

capacity of your generator, adjust the load until both wattage requirements are met. Other-

wise you will overload the generator, and cause damage to the engine and your electrical

device(s).

CALCULATING THE WATTAGE OF YOUR DEVICE(S)

Connect electrical devices running on AC current according to their wattage requirements. Calculate the total run-

ning wattage and starting wattage of the device(s) you wish to connect, and MAKE SURE that they are within the

capacity of your generator and the capacity of each individual outlet.

NOTE: Become familiar with the functions and capacity of each component on the control panel before con-

necting electrical devices. See page 11 for more information about the components of the control panel. Do not

overload generator or individual panel receptacles. Do not connect 50Hz or 3-phase loads to the generator.

USING YOUR GENERATOR

CONNECTING ELECTRICAL DEVICES

When the rated wattage requirement of each electrical device has been determined, add these numbers to ﬁnd the

total rated wattage needed. If this number exceeds the rated wattage (6500W) of the generator, DO NOT connect all

these devices. Select a combination of electrical devices with a total rated wattage lower than or equal to the rated

wattage of the generator.

CAUTION! Become familiar with the markings on the control panel before connecting electrical devices. Do

not connect 3-phase or 50Hz loads to the generator.

1. Before connecting electrical devices, allow the generator to run for a few minutes to stabilize the speed and volt-

age output.

2. Make sure that all devices are turned off. Start plugging in each electric device, from the highest wattage to the

lowest. Check the power indicator light (green) to ensure the generator is producing power.

3. Do not overload the generator or individual panel receptacles. If an overload occurs, one or more circuit breakers

will trip. Unplug all electrical devices, then press the circuit breaker to reset it. If it will not reset, wait a few minutes

for it to cool down. Check the total wattage of the devices and reduce the load if it exceeds the capacity of the gen-

erator. Then, plug the loads back in one by one.

NOTE: If the reset button or circuit breaker does not reset, wait several minutes and try again. If problem still per-

sists, please call 1-847-429-9263 M-F 8-5 CST, or email [email protected].

SWITCHING FUELS

To maximize your generator's lifespan, we recommend removing

all loads from the generator before switching between gasoline

and LPG. If this is not possible, reduce loads as much as possible

in order to ensure a smooth switch. Your generator is rated to

handle a higher load when running on gasoline than on LPG, so

keep this in mind when planning your fuel usage. To switch fuels:

1. Make sure you have enough gasoline or propane. If switching

to propane, make sure the propane regulator and

hose are securely attached to the propane cylinder and the pro-

pane inlet on the generator, and that the propane cylinder

valve is turned ON.

2. Turn the fuel selector switch (Fig. 13) to the desired fuel source.

NOTE: For power outages, permanently installed, stationary generators are better suited for providing backup

power to your home. Even a properly connected portable generator can become overloaded. This may result in

overheating or stressing the machine’s components, possibly leading to generator failure.

WARNING! Generator should only be connected to electrical devices, either directly or with an extension

cord. NEVER CONNECT TO A BUILDING ELECTRICAL SYSTEM without a qualiﬁed electrician and connected to

a transfer switch as a separately derived system. Such connections must comply with local electrical laws and

codes. Failure to comply can create a back-feed, which may result in serious injury or death to utility workers.

CIRCUIT BREAKERS (FIG. 14)

The 30A circuit breaker protects the NEMA TT-30R outlet. The 20A circuit breakers protect the NEMA 5-20R outlets.

The 25A circuit breakers each protect one leg of the NEMA L14-30R outlet. The circuit breakers will activate when

the outlets exceed the indicated amperage. When the circuit breaker activates, turn off and disconnect the device

from its respective outlet and press the circuit breaker to reset.

Fig. 14

USING YOUR GENERATOR

CO SENSOR INFORMATION

The CO Watchdog carbon monoxide monitoring system (Fig.

15 - 1) measures the accumulation of poisonous CO gas

while the generator is running. If the level of CO gas gets too

high, the CO Watchdog system will automatically shut down

the generator. This system is not a substitute for an indoor

CO alarm.

Whenever the CO Watchdog system shuts down the genera-

tor, the LED on the generator control panel (Fig. 15 - 1) will

blink red for at least 5 minutes after the generator is shut

down. If you notice that the LED is blinking red, vacate the

area immediately. Go to an open, outdoor area. Ventilate

the area around the generator thoroughly before returning.

Let the generator stay shut down for a few minutes before

restarting the engine. This should allow carbon monoxide to

dissipate from the area. If you restart the generator and the

CO Watchdog detects that CO levels are still too high, it will

shut down the generator again. If CO levels are low enough,

the generator will run normally.

Ensure that the generator is located in an open outdoor area, with the exhaust pointing away from occupied struc-

tures, and pointing away from the prevailing winds, such that those winds do not blow engine exhaust towards the

sensor module. If anyone experiences dizziness, headaches, nausea, fatigue, or other symptoms of CO poisoning,

get to fresh air immediately and seek the attention of a qualiﬁed medical professional. Follow all other directions in

this manual regarding the connection and disconnection of electrical devices when starting or shutting down the

generator.

When starting the generator, the CO Watchdog LED on the panel may ﬂash. This indicates that the system is running

a self-test procedure, and does not indicate a problem.

If the CO Watchdog LED on the panel is yellow, a system error has occurred, or the CO sensor has reached the end

of its life. Contact WEN customer service (1-847-429-9263, M – F 8 – 5 CST, or [email protected])

for assistance.

When operating your generator, please note the following:

• The CO Watchdog does not discriminate in its input; any source of carbon monoxide in the area around the genera-

tor could cause it to activate. If the CO Watchdog LED is blinking red, safety measures should be taken immediately.

• Tampering with, disconnecting, or bypassing the CO sensor could cause hazardous conditions, including but not

necessarily limited to injury or death, and will void your warranty. The generator will not run with the CO sensor

disconnected or bypassed, or if the CO sensor indicates an error.

• The CO sensor has a lifetime of about 7 years, and is capable of monitoring its lifetime. If your generator shows

an error light several years after purchase, it may be time to replace the CO sensor. Contact WEN customer service

for assistance.

NOTE: if the generator is oriented so that the

engine exhaust is blown towards the CO sensor,

the generator may shut down.

Fig. 15

SHUTTING OFF YOUR GENERATOR

CAUTION! Unplugging running devices can cause damage to the generator. Never stop the engine with elec-

trical devices connected and running.

OPTION 1: AUTOMATIC FUEL SHUTOFF (GASOLINE ONLY)

Your generator is equipped with automatic fuel shutoff. This feature turns off the ﬂow of fuel, allowing for the gen-

erator to use up the remaining fuel from the carburetor before turning off. This prolongs the lifespan of the generator

by preventing build-up and blockages caused by stagnant fuel inside of a carburetor.

1. Turn off all electrical devices prior to unplugging them from

the generator. Unplugging running devices can cause damage to

the generator.

2. Allow the generator to run at no load for a few minutes to sta-

bilize the internal temperatures.

3. Turn the fuel valve (Fig. 16 - 1) to the OFF position.

4. The engine will continue to run until the majority of the fuel in

the carburetor is consumed, which takes a few minutes. It will

then shut off automatically. This feature helps to prevent the car-

buretor from being clogged by stale fuel, extending your genera-

tor’s lifespan.

6. Push the engine switch (Fig. 17) to the OFF position.

OPTION 2: MANUAL SHUTOFF

WARNING! Allow the generator to cool down before touching areas that become hot during use.

CAUTION: Allowing gasoline to sit in the fuel tank for long periods of time can make it difﬁcult to start the gen-

erator in the future. Never store the generator for extended periods of time (over 2 months) with fuel in the fuel

tank. Refer to “Storing the Generator.”

IMPORTANT: Always ensure that the fuel valve and the engine switch are in the OFF position when the genera-

tor is not in use.

In case you are in a hurry and do not want to wait for the generator to automatically shut down, the manual shutoff

feature is available. However, this method will leave stagnant fuel in the carburetor, possibly causing blockages,

a shortened lifespan, and other maintenance issues. If this approach is frequently taken, make sure to drain your

carburetor before any long storage periods.

1. Turn off all electrical devices prior to unplugging them from the generator. Unplugging running devices can cause

damage to the generator.

2. Push the engine switch to the OFF position.

OPTION 3: LPG SHUTOFF

1. Turn off all electrical devices prior to unplugging them from the generator. Unplugging running devices can cause

damage to the generator. Never start or stop the generator with electrical devices plugged in or turned on.

2. Let the engine run at no-load for several minutes to stabilize internal temperatures of the engine and generator.

3. Make sure the fuel valve is OFF and then turn the engine switch to the OFF position.

IMPORTANT GENERATOR MAINTENANCE TIPS:

• Drain your carburetor after each use and before storage to prevent it from clogging.

• Do not store the generator with fuel inside the tank for more than 2 months - the fuel will go bad.

• Run the generator for at least 20 minutes every month to charge the battery and maximize lifespan.

CLEANING THE GENERATOR

Keep the generator clean to prevent improper operation or machine damage from dirt and debris. Inspect all venti-

lation openings on the generator. These openings must be kept clean and unobstructed. If the generator becomes

dirty, use a damp cloth to wipe exterior surfaces. Use a soft bristle brush to loosen dirt and oil and use a vacuum to

pick up loose dirt. Use low pressure air (not to exceed 25 PSI) to blow away dirt.

CAUTION! Never clean the generator when it is running! Never clean with a bucket of water or a hose. Water

can get inside the working parts of the generator and cause corrosion or a short circuit.

NOTE: Failure to properly maintain the generator will void the warranty.

CHECKING / ADDING OIL

Check the oil level before each use and every 8 hours of operation (refer to Table 4).

The oil capacity of the generator engine is 30.4 ﬂ. oz. (0.90 L). Add oil when the oil level is low. For proper type and

weight of oil refer to “add oil” portion of the “Generator Preparation” section. This is a critical step for proper engine

starting. The generator is equipped with a with low-oil shut down to protect it from running without oil.

To check the oil level and add oil:

1. Make sure the generator is on a level surface. Do not tilt the generator, as oil will ﬂow into engine areas and cause

damage. Keep generator level!

2. Remove the dipstick and wipe it with a clean rag.

3. Insert the dipstick into the oil ﬁll opening without screwing

in. Remove the dipstick to check the oil mark (Fig. 18). Add oil if

the oil mark covers less than one half of the dipstick.

4. Using a funnel or appropriate dispenser, slowly add more oil.

Repeat the step above until the oil mark reaches the top of the

dipstick. Do not over ﬁll.

5. Reinstall dipstick and wipe clean any spilled oil with a rag.

MAINTENANCE

DRAINING THE CARBURETOR

We recommend draining the carburetor after every use and before storing the generator. Draining the carburetor

can prevent the fuel from clogging up the carburetor; a clogged carburetor can prevent the generator from starting.

1. With the help of another person, place the

generator on an elevated platform such as a

table or desk.

2. Make sure that the engine switch is pressed

to OFF and the fuel valve is in the OFF posi-

tion. This will allow only the fuel left inside the

carburetor to be drained out.

3. The carburetor (Fig. 19 - 1) can be ac-

cessed on the left of the generator, right be-

hind the air ﬁlter.

4. Prepare an approved gasoline-storage con-

tainer and a funnel.

5. Open up the carburetor drain screw (Fig.

17 - 2) with a Phillips-head screwdriver and

drain out any gasoline that has built up inside

the carburetor through the included funnel

into the approved gasoline-storage container.

6. Once the fuel has drained, tighten the drain

screw with the screwdriver.

NOTE: Make sure to drain your carburetor be-

fore storing the generator for long periods of

time.

MAINTENANCE

AIR FILTER MAINTENANCE

Check every 50 hours of operation (refer to Table 4 - Recommended Maintenance Schedule).

Routine maintenance of the air ﬁlter helps maintain proper airﬂow to the carburetor. Occasionally check that the air

cleaner is free of excessive dirt.

To inspect and clean the air ﬁlter:

1. Remove the air ﬁlter cover (Fig. 20 - 1) by unscrewing the

cover lock knob (Fig. 20 - 2) at the bottom of the air ﬁlter

cover.

2. Remove the foam, sponge-like air ﬁlter element from the

casing. Wipe excessive oil and any dirt from inside of the air

ﬁlter casing.

3. Check the foam, sponge-like air ﬁlter element.

a) Good elements can be washed in soapy water. Dry the

element in clean cloth (do not twist it). Add a few drops of

engine oil to the air ﬁlter element and spread it evenly. A

small amount of oil left in the element is normal and neces-

sary for the engine to work properly.

WARNING! Running the engine with a dirty, damaged or missing air ﬁlter element can result in danger to the

operator and cause the engine to wear out prematurely.

SPARK ARRESTOR MAINTENANCE

Inspect and clean the spark arrestor every 100 hours of operation. The spark arrester is located outside the mufﬂer,

which gets very hot during operation. Allow the engine to cool completely before servicing the spark arrester. To

inspect and clean the spark arrester:

1. Remove the two Phillips-head screws that secure the spark

arrestor to the mufﬂer (Fig. 21 - 1).

2. Remove the spark arrestor screen.

3. Carefully clean and remove the carbon deposits from the

spark arrestor screen with a wire brush. Replace the spark

arrestor if it is damaged (replacement spark arrestors can be

purchased from wenproducts.com by searching the part no.

DF8000X-027.1).

4. Reinstall the spark arrestor in the mufﬂer and secure it in

place with the screws.

b) Damaged elements should be replaced with a new one. Replacement air ﬁlters can be purchased from wen-

products.com by searching part number DF8000X-137.

4. Reinstall the air ﬁlter element and air ﬁlter cover.

MAINTENANCE

SPARK PLUG MAINTENANCE

Refer to Recommended Maintenance Schedule in Table 4 for maintaining the spark plug. The spark plug is impor-

tant for proper engine operation. Check the spark plug regularly to maintain proper engine operation. A good spark

plug should be intact, free of deposits, and properly gapped.

To inspect or replace the spark plug:

1. Gently pull on the spark plug boot (Fig. 22 - 1) to remove it.

Be careful not to tear any insulation or wire.

2. Use the included spark plug socket (Fig. 23) to unscrew and

then carefully remove the spark plug from the engine.

TIP: There is limited space for the wrench to turn. Use both

rows of holes in the spark plug wrench to gain leverage to

loosen the plug.

3. Visually inspect the spark plug. If it is cracked or chipped,

or if the electrodes are worn or burned, discard it and replace

with a new spark plug.

We recommend replacing with a Torch F7RTC (NGK BPR7ES)

spark plug (part no. DF8000X-122), available for purchase at

wenproducts.com.

4. If re-using the spark plug, use a wire brush to clean any dirt

from around the spark plug base, then re-gap the spark plug.

5. Measure the plug gap with a spark plug gap gauge. The gap

should be 0.028 in. - 0.031 in. (0.7mm - 0.8mm) (Fig. 24).

Carefully adjust the gap if necessary.

6. Screw the spark plug back into the spark plug hole using

the spark plug wrench. Do not over-tighten spark plug. Rec-

ommended tightening of spark plug is 20 - 22 ft-lbs (27 - 30

Nm).

7. Reinstall the spark plug boot, spark plug rubber cover, and

service panel.

MAINTENANCE

DRAINING / CHANGING OIL

Change the oil according to the Recommended Maintenance Schedule in Table 4. Change the oil MORE OFTEN if

operating under heavy load or high ambient temperatures. It is also necessary to drain the oil from the crankcase if

it has become contaminated with water or dirt. Changing the oil when the engine is warm allows for more-complete

drainage.

To change engine oil:

1. With the help of another person, place the generator on an

elevated platform such as table or workbench.

NOTE: To avoid possible gasoline spills from the carburetor

bowl, drain the carburetor before draining oil.

2. Prepare an approved oil-storage container and place it be-

low the oil drainage bolt (Fig. 25 - 1) to catch oil as it drains.

4. Use a 17mm socket to loosen and remove the oil drainage

bolt, and allow oil to drain from the engine completely.

5. Replace and tighten the oil drainage bolt after the oil has

drained.

NOTE: Never dispose of used engine oil in the trash or down

a drain. Please call a local recycling center or auto garage to

arrange proper oil disposal.

111

6. Unscrew the oil dipstick. Using a funnel or appropriate dispenser, add 30.4 ﬂ. oz. (0.90 L) of clean engine oil into

the oil ﬁll. Check the oil level periodically using the dipstick. Do not over ﬁll.

TIP: Your WEN generator is compatible with the WEN GNA273 Magnetic Oil Dipstick (not included), available for

purchase at wenproducts.com. The dipstick’s industrial-strength magnetic tip will collect metal shavings from your

generator’s oil compartment to help preserve the engine and extend your generator’s lifespan.

MAINTENANCE

DRAINING THE FUEL TANK

Drain and clean the fuel tank each year, or before storing the generator for longer than two months.

To drain the fuel tank and carburetor:

1. Locate the carburetor (Fig. 26 - 1). It can be accessed on

the back of the generator, right beside the air ﬁlter.

2. Prepare an approved gasoline-storage container and a

funnel.

3. Remove the fuel cap (Fig. 27 - 1) and turn the fuel valve

(Fig. 28 - 1) ON.

4. Open up the carburetor drain screw (Fig. 26 - 2) with a

Phillips screwdriver. Fuel will start draining from the carbu-

retor and fuel tank through the funnel.

NOTE: The draining process may take a few hours, depend-

ing on the amount of fuel in your gas tank.

5. Once fuel is completely drained from the tank, reinstall the

fuel cap and turn the fuel valve (Fig. 28 - 1) OFF. Tighten the

drain screw with the screwdriver.

6. Start and run the generator until the fuel runs out.

7. Store the emptied gasoline in a suitable place. DO NOT

store ﬂammable materials near the gasoline.

CAUTION: Store the emptied gasoline in a suitable place.

Never store fuel for more than 2 months.

MAINTENANCE

BATTERY MAINTENANCE/STORAGE

The battery will receive charge when the engine is running. Remember to run the generator once a month for 20-30

minutes to charge the battery. A charged battery will allow you to start the generator using the electric start switch

during your next time of need. If the battery is out of charge, you may start the generator using the recoil starter. If

the generator is not used for a long period, it is recommended to disconnect the quick-connector from the battery

to protect it from losing charge.

TIP: You can also connect the battery to an automatic trickle charger to keep the battery charged. If using a trickle-

charger, charge the battery at room temperature.

Lithium-ion batteries can be damaged or suffer a shortened lifespan if they are charged in very cold temperatures

(below freezing). If you expect to store the generator in temperatures below 25°F (-5°C), we recommend removing

the battery from the generator and storing it indoors. If using the generator in temperatures below 25°F (-5°C), we

recommend running the generator for at least 15 minutes with the battery removed, or the quick-connector cable

disconnected and covered with the rubber sheath, and then connecting the battery. This will allow the area around

the generator to warm up, and will greatly reduce the chance of damage to the battery.

To reinstall/replace the battery:

1. Unhook the battery strap from the engine frame. Remove the battery and disconnect the quick-connector.

2. Replace with an identical new battery (part no. DF8000X-065).

3. Connect the new battery by connecting the two ends of the quick connector together.

4. Secure the battery to the generator frame using the battery strap.

NOTE: Always recycle used batteries in accordance with local laws and regulations. Contact your local solid waste

collection site or recycling facility to obtain information on local recycling processes.

WARNING! It is best to store the battery indoors at room temperature. Do not store your battery outside in

the winter, where temperatures may go below 25°F (-5°C), or in any location where temperatures may exceed

104°F (40°C), such as in direct sunlight or inside a vehicle or metal building during the summer.

TRANSPORTATION & STORAGE

WARNING! Avoid direct sunlight inside a vehicle. If the generator is left in an enclosed vehicle for many

hours, the high temperature could cause the fuel to vaporize and result in a possible explosion.

WARNING! Store the generator upright in a cool and dry location, away from sources of heat, open ﬂames,

sparks or pilot lights.

TRANSPORTING THE GENERATOR

To prevent fuel spillage when transporting, be sure to perform the following:

1. Tighten the fuel cap.

2. Push the engine switch to OFF.

3. Drain the fuel tank if possible. Refer to section "DRAINING THE FUEL TANK."

4. Keep the generator upright. Never place the generator on its side or upside down - doing so could damage the

internal components of the generator and make it difﬁcult to start.

STORING THE GENERATOR

Shut off the generator and allow the unit to cool to room temperature before storing it. NEVER place any type of

storage cover on the generator while it is still hot. Do not obstruct any ventilation openings.

Follow the procedures below for properly storing your generator. We highly recommend running your generator

once a month for 20 to 30 minutes. Plug in a small load in to ensure there is proper power output.

PRODUCT DISPOSAL

Do not dispose of a used generator or parts with your household waste. This product contains electrical or elec-

tronic components that should be recycled. Please take this product to your local recycling facility for responsible

disposal to minimize its environmental impact.

Do not dispose of used oil or fuel in the trash or down a drain. Please contact your local recycling center or auto

garage to arrange proper oil/fuel disposal.

Please recycle the packaging and electronic components where facilities exist. Please contact your

local auto garage or recycling facility to properly dispose of oil/fuel.

For Short Periods (30 to 60 Days):

• Drain the carburetor.

• Disconnect the quick-connector from the battery.

• Add fuel stabilizer: Follow the suggested por-

tions and instructions of your preferred stabilizer.

Run the engine for 15 to 20 minutes, allowing the

fuel stabilizer to mix with the gasoline and circulate

through the carburetor, and then top off with fuel.

Filling the fuel tank full reduces the amount of air in

the tank and helps ﬁght deterioration of fuel.

For Extended Periods (Over 60 Days):

• Disconnect the quick-connector from the battery.

• Drain the fuel tank and carburetor (see “DRAINING

THE FUEL TANK”). Never store generator with fuel

in the tank for more than two months.

• Change the engine oil (see “CHANGING OIL”).
