GENERAL SAFETY RULES

WORK AREA SAFETY

1. Keep work area clean and well lit. Cluttered or dark

areas invite accidents.

2. Do not operate power tools in explosive atmo-

spheres, such as in the presence of ﬂammable liquids,

gases or dust. Power tools create sparks which may ig-

nite the dust or fumes.

3. Keep children and bystanders away while operating

a power tool. Distractions can cause you to lose control.

ELECTRICAL SAFETY

1. Power tool plugs must match the outlet. Never mod-

ify the plug in any way. Do not use any adapter plugs

with earthed (grounded) power tools. Unmodiﬁed plugs

and matching outlets will reduce risk of electric shock.

2. Avoid body contact with earthed or grounded surfac-

es such as pipes, radiators, ranges and refrigerators.

There is an increased risk of electric shock if your body

is earthed or grounded.

3. Do not expose power tools to rain or wet conditions.

Water entering a power tool will increase the risk of elec-

tric shock.

4. Do not abuse the cord. Never use the cord for car-

rying, pulling or unplugging the power tool. Keep cord

away from heat, oil, sharp edges or moving parts.

Damaged or entangled cords increase the risk of electric

shock.

5. When operating a power tool outdoors, use an ex-

tension cord suitable for outdoor use. Use of a cord

suitable for outdoor use reduces the risk of electric

shock.

6. If operating a power tool in a damp location is un-

avoidable, use a ground fault circuit interrupter (GFCI)

protected supply. Use of a GFCI reduces the risk of elec-

tric shock.

PERSONAL SAFETY

1. Stay alert, watch what you are doing and use com-

mon sense when operating a power tool. Do not use a

power tool while you are tired or under the inﬂuence

of drugs, alcohol or medication. A moment of inatten-

tion while operating power tools may result in serious

personal injury.

2. Use personal protective equipment. Always wear

eye protection. Protective equipment such as a respira-

tory mask, non-skid safety shoes and hearing protection

used for appropriate conditions will reduce the risk of

personal injury.

3. Prevent unintentional starting. Ensure the switch is

in the off-position before connecting to power source

and/or battery pack, picking up or carrying the tool.

Carrying power tools with your ﬁnger on the switch or

energizing power tools that have the switch on invites

accidents.

4. Remove any adjusting key or wrench before turning

the power tool on. A wrench or a key left attached to a

rotating part of the power tool may result in personal

injury.

5. Do not overreach. Keep proper footing and balance

at all times. This enables better control of the power

tool in unexpected situations.

6. Dress properly. Do not wear loose clothing or jew-

elry. Keep your hair and clothing away from moving

parts. Loose clothes, jewelry or long hair can be caught

in moving parts.

Safety is a combination of common sense, staying alert and knowing how your item works. The term “power tool”

in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

SAVE THESE SAFETY INSTRUCTIONS.

WARNING! Read all safety warnings and all instructions. Failure to follow the warnings and instructions may

result in electric shock, ﬁre and/or serious injury.

GENERAL SAFETY RULES

7. If devices are provided for the connection of dust

extraction and collection facilities, ensure these are

connected and properly used. Use of dust collection

can reduce dust-related hazards.

POWER TOOL USE AND CARE

1. Do not force the power tool. Use the correct power

tool for your application. The correct power tool will

do the job better and safer at the rate for which it was

designed.

2. Do not use the power tool if the switch does not turn

it on and off. Any power tool that cannot be controlled

with the switch is dangerous and must be repaired.

3. Disconnect the plug from the power source and/or

the battery pack from the power tool before making

any adjustments, changing accessories, or storing

power tools. Such preventive safety measures reduce

the risk of starting the power tool accidentally.

4. Store idle power tools out of the reach of children

and do not allow persons unfamiliar with the power

tool or these instructions to operate the power tool.

Power tools are dangerous in the hands of untrained us-

ers.

5. Maintain power tools. Check for misalignment or

binding of moving parts, breakage of parts and any

other condition that may affect the power tool’s opera-

tion. If damaged, have the power tool repaired before

use. Many accidents are caused by poorly maintained

power tools.

6. Keep cutting tools sharp and clean. Properly main-

tained cutting tools with sharp cutting edges are less

likely to bind and are easier to control.

7. Use the power tool, accessories and tool bits, etc.

in accordance with these instructions, taking into ac-

count the working conditions and the work to be per-

formed. Use of the power tool for operations different

from those intended could result in a hazardous situa-

tion.

8. Use clamps to secure your workpiece to a stable

surface. Holding a workpiece by hand or using your

body to support it may lead to loss of control.

9. KEEP GUARDS IN PLACE and in working order.

SERVICE

1. Have your power tool serviced by a qualiﬁed repair

person using only identical replacement parts. This

will ensure that the safety of the power tool is main-

tained.

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.

CALIFORNIA PROPOSITION 65 WARNING: This product contains chemicals and produces exhaust known

to the State of California to cause cancer, birth defects and other reproductive harm. For more information, visit

1. Always ground the generator before using it to maxi-

mize safety (see “Ground the Generator” section).

2. Do not overﬁll fuel tank, as gasoline may expand

during operation. Do not ﬁll to the very top of the tank.

Leave room for gasoline expansion. Always check for

spilled fuel before operating.

3. If any part of the generator, electrical device or pow-

er cord is broken, damaged, or defective, make sure

it is repaired or replaced before operation. Service

should only be performed by a qualiﬁed technician. Do

not use receptacles or cords that show signs of damage,

such as broken or cracked insulation.

4. Use a ground fault circuit interrupter (GFCI) in highly

conductive areas such as metal decking or steel work.

Extension cords with in-line GFCIs are recommended for

these operations to maximize safety.

5. If connecting the generator to a building’s electri-

cal system for standby power, you MUST consult a

qualiﬁed electrician and install a transfer switch. 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.

6. Never modify the generator in any way. Modifying

or using the machine for any other purpose for which it

is not designed may result in serious injuries, machine

damage and voiding of the warranty.

The following section describes the necessary steps to prepare the generator for use. If you are unsure about how to

perform any of the steps please call 1-847-429-9263 (M-F 8-5 CST) for customer service. Failure to perform these

steps properly can damage the generator or shorten its life.

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 37.2 ﬂ oz (1.1 L).

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.

TO ADD OIL:

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

gine is OFF before adding or checking oil.

2. Unscrew the oil dipstick (Fig. 3) 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 to the upper ﬁll line so you can visually see the oil

coming halfway up the oil ﬁll threads. See Fig. 4.

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

any spilled oil.

CAUTION! 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. Follow the instruc-

tions on the next page to check the oil level.

stick (or when you can see the oil coming halfway up the

oil ﬁll threads). See Fig. 5.

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.

ONLY use 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 4.2 US gallons (16L). Do

not mix oil with gasoline.

Follow the instructions on the next page to add gasoline.

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.

OIL LEVEL SHUTDOWN

To protect the unit from damage, the generator is equipped with a low-oil-pressure shutoff that will automatically

shut down the engine when the oil level is too low. The oil level of the engine should be checked before each start

to ensure that the engine crankcase contains sufﬁcient lubricant.

STEP 2 - ADD/CHECK FUEL

GENERATOR PREPARATION

Fig. 5

TO ADD GASOLINE:

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

engine is OFF before adding or checking the fuel.

2. Unscrew the fuel cap (Fig. 6) and set it aside. The fuel

cap may be tight and hard to unscrew.

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

not to overﬁll. Reinstall fuel cap and wipe clean any spilled

gasoline with a dry cloth.

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.

TO CHECK GAS LEVEL (before every subsequent start):

1. Before starting the generator, check the fuel gauge (Fig. 7) to see if there is sufﬁcient fuel inside the tank:

• E = Empty

• F = Full

2. If the tank is empty add gasoline to the gas tank. See above section, "To Add Gasoline".

STEP 3 - CONNECT THE BATTERY

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 instruc-

tions 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 meet-

ing 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 battery 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 appears to

be undamaged. The battery cells inside the battery may have suffered serious damage. In such instances, please

read the waste disposal information on p. 31 for proper battery disposal.

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.).

NOTE: Grounding wire and grounding rods are not

included with the generator. A generally acceptable

grounding wire is a No. 12 AWG (American Wire

Gauge) stranded copper wire. Grounding codes

can vary by location. Contact a local electrician to

check the area codes.

ABOUT THE BATTERY (CONT.)

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 as-

sistance.

7. DO NOT SHORT CIRCUIT. Batteries will short circuit if a metal object makes a connection between the positive

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 battery is 25°F – 104°F. The generator is shipped with the lith-

ium-ion battery’s negative (-) terminal disconnected to maximize safety. To start the generator using electric start,

the battery must be connected.

To connect the battery:

1. Remove the black battery bracket by removing the two Phillips-head bolts that hold the battery bracket in place.

Pull out the battery for easier access.

2. Pull back the protective cover from the red (+) lead near the battery.

GENERATOR PREPARATION

3. Attach the red (+) lead to the positive (+) terminal on the

battery, using the nut and bolt.

4. Repeat for the black (-) battery lead. Secure it to the

negative (-) terminal on the battery).

STEP 4 - GROUNDING THE GENERATOR

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

the generator should be properly grounded.

1. Attach one end of the grounding wire to the grounding

nut (Fig. 7). Tighten the nut to secure the grounding wire.

2. Connect the other end of the grounding wire to a copper,

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

Fig. 7

Grounding Nut

WARNING! Failure to properly ground the generator

increases your risk of electric shock.

STARTING THE GENERATOR

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

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

tion 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. Refer to "Step 3 - 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.

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 unless a qualiﬁed electrician has connected the generator 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.

Follow the instructions on the next page to start your generator.

tempts, please consult the troubleshooting guide be-

fore attempting to start the generator again. If prob-

lems persist, please contact WEN customer service

(see front page of manual).

6. Slowly push the choke button into the OPEN / RUN

position (Fig. 9).

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 applicable 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 af-

ter the ﬁrst 25 hours. You may run the generator at full load after the 8-hour oil change. Refer to the Recommended

Maintenance Schedule in Table 4 for the full maintenance schedule.

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.

Generator

Wattage

Capacity

GENERATOR RUNNING (RATED) WATTS GENERATOR STARTING (SURGE) WATTS

7000W 8750W

What this means:

The generator can produce a maximum of

7000W on a continuous basis to supply on-

going power to your electronic devices.

NOTE: Also check the rated amperage for

each outlet and make sure not to overload

the individual 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 8750W 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, or you may refer to Table 2 - Estimated

Wattages of Common Electrical Appliances.

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 (rated) wattage.

This wattage should NOT exceed the run-

ning wattage of 7000W.

It is recommended to maintain a load at or

below 6300W (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 starting (surge) wattage.

This wattage should NOT exceed the starting

wattage of 8750W.

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

ity of your generator, adjust the load until both wattage requirements are met. Otherwise you

will overload the generator, and cause damage to the engine and your electrical device(s).

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

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

age output.

2. Select the device with the highest wattage, and make sure it is turned off. Plug the device into the matching gen-

erator outlet and then turn the device on. Allow the engine to stabilize.

3. Repeat step 2 to plug in each additional device. Do not attempt to plug in or start multiple devices at the same

time.

NOTE: You may use the 120V and 240V outlets at the same time. This generator uses two windings to supply power.

One winding powers the 5-20R outlets and one leg of the L14-30R outlet. The other winding powers the TT-30R

outlet and the other leg of the L14-30R outlet. Consult the wiring diagram on p. 34 for more details.

ECO-MODE SWITCH

This generator is equipped with an Eco-Mode Idle Control Switch. Engaging this switch allows the system to regu-

late the engine speed and automatically adjust its fuel consumption to match the required load. When the electrical

load changes, the generator engine will automatically speed up and slow down as needed. This reduces fuel con-

sumption and noise levels, while extending runtime and engine’s lifespan.

Keep this switch engaged ONLY when the power load requirement is less than 5250W (75% of the rated watts). Do

not engage the Eco-Mode Switch when the total load is more than 5250W. The generator engine must run at full

speed to supply power for anything over 5250W.

CIRCUIT BREAKER

The circuit breakers will activate when the load on the outlet exceeds the breaker's rating. When the circuit breaker

activates, turn off and disconnect the device from its respective outlet, and press the circuit breaker to reset.

IN CASE OF OVERLOAD

If your generator becomes overloaded from too much drawn wattage, the overload light (red) on the control panel

will light up. Follow the instructions below when an overload occurs:

• When you’ve overloaded the generator, the overload light will stay on and the overload reset button will activate

to cut off the output in 3 to 16 seconds, depending on the load. Reduce the load by turning off and disconnecting

your electrical device(s) until the overload light turns off. Wait about ﬁve minutes and then press the activated

reset button to reset the circuit. If no power is produced after resetting, turn off and disconnect all electrical

devices and restart your generator.

• The pattern in which the overload light blinks gives diagnostic information about the problem. Refer to the chart

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

cord. NEVER CONNECT TO A BUILDING ELECTRICAL SYSTEM unless a qualiﬁed electrician has connected the

generator to a transfer switch as a separately derived system. Such connections must comply with local electri-

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

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.

SOME NOTES ABOUT POWER CORDS

Refer to the following chart in determining the necessary gauge extension cord for each of your devices. Round up

to the higher amperage in the chart to maximize safety.

USING YOUR GENERATOR

CO SENSOR INFORMATION

The CO Watchdog carbon monoxide monitoring system (Fig.

10 - 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. 10 - 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. 10

SHUTTING OFF THE GENERATOR

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

trical devices connected and running.

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 generator

is not in use.

MANUAL 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 engine run at no-load for several minutes to stabilize

internal temperatures of engine and generator.

3. Turn the fuel valve to the OFF position (Fig. 11). Let the

generator run until the fuel is used up.

4. Flip the engine switch to the OFF position.

5. Drain the carburetor. Refer to "Draining The Carburetor."

NOTE: If for some reason (e.g. refueling, moving the generator, etc.) you need to shut down the generator

quickly, simply ﬂip the engine switch to STOP. However, doing this will allow fuel to remain in the carburetor, and

will lead to problems if the carburetor is not drained after use.

Fig. 11

OFF

WARNING! Never perform maintenance operations while the generator is running. Before maintaining or

servicing the generator, turn OFF the generator, disconnect all devices and allow the generator to cool down.

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

RECOMMENDED MAINTENANCE SCHEDULE

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. Prepare an approved oil-storage container underneath the oil drainage hose (Fig. 12 - 1) to catch oil as it drains.

Fig. 12

MAINTENANCE

WARNING! 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.

CLEANING YOUR GENERATOR

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

tion 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.

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 gen-

erator engine is 37.2 ﬂ. oz. (1 L). Add oil when the oil level is low. For the proper type and weight of oil refer to

page 3. 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/or add oil refer to "Step 1 - Add/Check Oil."

NOTE: To avoid possible gasoline spills from the carburetor

bowl, drain the carburetor (see p. 28) before draining oil.

2. Remove the oil drainage hose from its harness behind

the panel. Open the oil drainage valve by turning the lever,

and allow oil to drain from the engine completely.

3. Close the oil drainage valve 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.

4. Unscrew the oil dipstick. Using a funnel or appropriate

dispenser, add 37.2 ﬂ oz of clean engine oil into the oil ﬁll

until you can see oil coming up the threads of the oil ﬁll. Do

not over ﬁll.

5. Reinstall the oil dipstick and tighten it securely. Wipe

clean any oil spillage.

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.

NOTE: Make sure to drain your carburetor before

storing the generator for long periods of time.

DRAINING THE CARBURETOR

Drain the carburetor after every use and before storing

the generator (refer to Table 4). Draining the carburetor can

help prevent build-up and blockages caused by stagnant fuel

inside of the carburetor.

1. Prepare an approved gasoline-storage container under

the carburetor to collect the drained fuel. Close fuel valve.

2. The carburetor can be accessed from the backside of

the generator between the engine and the air ﬁlter. To drain

the carburetor, open up the carburetor drain screw with a

Phillips-head screwdriver (not included) and drain out any

gasoline that has built up inside. See Fig. 13.

3. Once the fuel has drained, close the drain screw.

INSPECTING/CLEANING THE AIR FILTER

Inspect and clean the air ﬁlter every 50 hours of operation (refer to Table 4). Routine maintenance of the air ﬁlter

helps maintain proper airﬂow to the carburetor. Occasionally check that the air ﬁlter is free of excessive dirt. Clean

air ﬁlter more frequently in dirty or dusty conditions.

1. Remove the air ﬁlter cover (Fig. 14 - 1) by unscrewing the

cover lock knob (Fig. 14 - 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

necessary for the engine to work properly.

b) Damaged elements should be replaced with a new

one. Replacement air ﬁlters can be purchased from

wenproducts.com.

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

INSPECTING/CLEANING THE SPARK ARRESTOR

Inspect and clean the spark arrestor every 100 hours of

operation (refer to Table 4). The spark arrestor is located

outside the mufﬂer, which gets very hot during operation.

Allow the engine to cool completely before servicing the

spark arrestor.

1. Remove the two bolts that secure the spark arrestor to

the mufﬂer. See Fig. 15.

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.

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

place with the screws.

SPARK PLUG MAINTENANCE

Inspect and change the spark plug every 100 hours of operation (refer to Table 4). The spark plug is important

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.

1. Gently pull on the spark plug boot to remove it. Be careful not to tear insulation or wire.

2. Use the included spark plug wrench (slide the handle into the hole on the wrench) to unscrew the spark plug from

the engine. 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 it with an F6RTC spark plug. These can be purchased from

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.

Instructions continue on the next page.

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

gap should be 0.7 to 0.8 mm (0.028-0.031 in). Carefully

adjust the gap if necessary. See Fig. 16.

6. Screw the spark plug back into the spark plug hole us-

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

Recommended tightening of the spark plug is ½ to ¾ of a

turn (15 ft-lb torque/20.33 Nm) after the spark plug gasket

contacts the spark plug hole.

7. Reinstall the spark plug boot over the spark plug.

DRAINING THE FUEL TANK

Drain and clean the fuel tank each year, or before storing

the generator for longer than two months.

1. Prepare an approved gasoline-storage container to collect

the drained fuel. Place it near the fuel valve (Fig. 17 - 1).

2. Turn the fuel valve to the OFF position.

3. Locate the fuel line between the fuel valve and the carbu-

retor. Disconnect the fuel line from the fuel valve.

NOTE: A small amount of fuel may leak from the fuel line

during removal.

4. Place a funnel below the fuel valve opening, and direct the

other end of the funnel over the prepared container.

5. Turn the fuel valve to the ON position to start draining the

fuel from the fuel valve opening. NOTE: The draining process

may take a few hours, depending on the amount of fuel in

your gas tank.

6. Once the fuel is completely drained, turn the fuel valve to

the OFF position.

7. Start and run the engine until the fuel runs out.

8. Drain the carburetor. Refer to "Draining The Carburetor."

CAUTION! Store the emptied gasoline in a suit-

able place. Never store fuel for more than 2

months.

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 during your next time of need.

IMPORTANT! If you do not plan to use the generator for a long period of time, we recommend DISCON-

NECTING the negative battery cable from the battery to protect the battery from losing charge. After disconnect-

ing the cable, cover the free end with an insulator such as electrical tape. You may also choose to use a trickle

charger (not included) to maintain battery charge.

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.

MAINTENANCE

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 negative (black) battery

cable disconnected and covered with an insulator such as electrical tape, 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.

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.

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.

TRANSPORTING THE GENERATOR

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

1. Tighten the fuel cap and turn the fuel valve to the OFF position.

2. Flip the engine switch to the STOP position.

3. Drain the fuel tank if possible. Refer to "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.

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

sparks or pilot lights.

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.

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.

TIP: Your WEN generator is compatible

with the WEN 56409 Generator Cover (not

included). It is available for purchase at

wenproducts.com.

PRODUCT DISPOSAL

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

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.

For Short Periods (30 to 60 Days):

• Drain the carburetor. Refer to "Draining The Car-

buretor."

• Add fuel stabilizer: Follow suggested portions

and instructions of your preferred stabilizer. Run

engine for 15 to 20 minutes, allowing fuel stabiliz-

er 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 negative lead from the battery.

Refer to "Battery Maintenance/Storage."

• Drain fuel tank and carburetor. Refer to "Draining

The Fuel Tank" and "Draining The Carburetor."

• Never store generator with fuel in the tank for

more than two months.

• Change engine oil. Refer to "Checking/Adding Oil."
