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

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.

GENERATOR PREPARATION

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’s crankcase is 44 ﬂ. oz. (1.3 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.

NOTE: Extend the lifespan of your generator by catching the

loose metal ﬁlaments that naturally build up inside the crank

case with the WEN Magnetic Dipstick (Model GNA273),

available for purchase at wenproducts.com.

TO CHECK OIL LEVEL (before every subsequent start):

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

engine 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.

4. If the oil mark covers less than one half of the dipstick,

slowly add oil until the oil mark reaches the top of the dip-

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 8.2 US gallons. 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

FUEL OPTION A: GASOLINE

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. 6) to see if there is sufﬁcient fuel inside the tank:

• E = Empty

• F = Full

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

WARNING! If using gasoline, the LPG tank must be shut OFF. If using LPG, the fuel valve on the generator

must be turned to the OFF position.

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.

GENERATOR PREPARATION

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

NOTE: LPG regulator inlet pressure is approximately 30 PSI at 0 °F, and 218 PSI at 100 °F.

• 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. Screw the female threaded end of the quick-connect adapter (Fig.

7A - 1) onto the male threaded ﬁtting on the generator (Fig. 7A - 2). DO

NOT use Teﬂon or other PTFE tape on this connection. Tighten it with the

included 22mm wrench.

3. 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. 7B).

3. Pull back the collar on the quick-connector on the LPG hose. Push it

fully over the male end of the adapter, then release the collar. Lightly pull

on the hose to ensure it is securely attached to the generator.

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

water on all connections. If bubbles appear, become larger in size, or

increase in number, a leak exists. Recheck all connections and perform

the test again. If the leak persists, it must be corrected before using the

generator. Contact a professional, certiﬁed LPG plumber for assistance.

CAUTION! Always position the LPG cylinder so the connection

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

hose.

WARNING! 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.

WARNING! 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.

GENERATOR PREPARATION

WARNING! BATTERY GIVES OFF EXPLOSIVE HYDROGEN GAS.

• Keep battery away from spark, ﬂame, or cigarette.

• Do not connect or disconnect battery while generator is running.

• Service or use battery only in well ventilated areas.

WARNING! Battery contains sulfuric acid. Battery acid is poisonous. Tilting the generator with the battery

installed can cause battery acid to spill.

• Wear protective clothing and eye wear when servicing battery.

• Keep out of reach of children.

• Do not tilt generator with battery installed.

• If battery acid gets on your skin, wash with water immediately.

• If battery acid gets in your eyes, ﬂush with water for at least 15 minutes and call a doctor immediately.

If battery acid is swallowed, call a doctor immediately. Drink a large amount of water or milk. Then drink milk of

magnesia or vegetable oil.

The generator comes with the battery disconnected for

safety. When using LPG or NG to run the generator, the

battery must be connected whether using electric or recoil

start. The battery must also be connected for electric start

when using gasoline, but the battery does not need to be

connected for recoil start on gasoline.

For a video of this procedure, please visit http://bit.

ly/44sb6C2.

To connect the battery:

1. Remove the rubber quick-connector covers.

2. Connect the two ends of the quick-connector on the

battery (Fig. 9) to the ends of the quick-connector on the

starter motor.

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

an extended period of time, we recommend DISCONNECT-

ING the quick connector. This will protect the battery from

losing its charge. Cover the ends with the rubber covers.

Alternatively, you can use a trickle charger (not included)

to maintain battery charge. A smart trickle / ﬂoat charger

is available for purchase at wenproducts.com (model no.

GNA12C).

STEP 3 - CONNECT THE BATTERY

If the battery is dead or disconnected, the generator will not start when using electric start on gasoline. The genera-

tor will also not start when using LPG or NG, regardless of starting method. The battery receives charge when the

generator is running. To help maximize your battery’s lifespan, and ensure it’s ready when needed, run your genera-

tor once a month, disconnect the quick connectors as outlined above, or connect the battery to a trickle charger.

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

GENERATOR PREPARATION

STEP 4 - GROUND THE GENERATOR

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

the generator should be properly grounded.

Ground the generator by tightening the grounding nut on

the front control panel (Fig. 10) against a grounding wire.

A generally acceptable grounding wire is a No. 12 AWG

(American Wire Gauge) stranded copper 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.

This kit should be installed by a qualiﬁed mechanic. You can order the kit at wenproducts.com by searching part

number TF1450X-HA36 (3000 - 6000 ft) and TF1450X-HA68 (6000 - 8000 ft). Refer to the instructions included

with your altitude kit for more information about installation.

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.

Fig. 10

STARTING YOUR 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 4 - 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.

BEFORE STARTING THE GENERATOR

1. Verify that the generator is outside on a dry, level sur-

face. Allow at least two feet of clearance on all sides of the

generator.

2. To maximize safety, check that the generator is properly

grounded (see “Ground the Generator”).

3. Check there is sufﬁcient level of oil in the crankcase. Add

oil if necessary (see “Add/check Oil”).

4. Verify the fuel selection dial is turned to the desired fuel

(gasoline, propane, or natural gas). Check that there is ad-

equate supply of the selected fuel.

5. Make sure all electrical devices are unplugged from the

generator during ignition. Otherwise it will be difﬁcult for

the engine to start.

7. Allow the engine to run for several minutes before attempting to connect any electrical devices. This allows the

generator to stabilize its speed and temperature. Follow the instructions in the next section for properly connecting

your electrical devices.

NOTE: In case you have had repeated failed attempts to start the engine, please consult the troubleshooting guide

before attempting to start the generator. If problems persist please call 1-847-429-9263, M-F 8-5 CST.

a. To start the engine with electric starter:

4. Insert the key and turn the engine switch to the

START position for 2-3 seconds. NOTE: If the engine

does not start, release the switch and try again. Keeping

the switch in the START position too long can damage

the starter.

5. When engine starts, release the switch to the ON po-

sition.

6. Slowly move the choke lever to the OPEN/RUN posi-

tion. If engine ﬁres, but does not continue to run, move

choke lever to CLOSE/START position and repeat start-

ing instructions.

b. To start the engine with recoil starter:

4. Turn the engine switch to the ON position.

5. Pull on the recoil starter handle slowly until a slight

resistance is felt, then pull quickly to start the engine.

Return cord gently into the recoil starter. Never allow

the cord to snap back.

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

Gasoline: 11500W Gasoline: 14500W

LPG: 10300W LPG: 12500W

NG: 8750W NG: 10500W

What this means:

The generator can produce a maximum of

11500W / 10300W / 8750W on a continuous

basis to supply ongoing power to your elec-

tronic 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 14500W / 12500W / 10500W for a

short period of time (seconds) to cover the

extra starting power required by your elec-

tronic 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 11500W / 10300W / 8750W.

It is recommended to maintain a load at or be-

low 10350W / 9270W / 7875W (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 14500W / 12500W / 10500W.

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.

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

SOME NOTES ABOUT POWER CORDS

Long or thin extension cords can drain the power pro-

vided to your electrical devices. Refer to the following

chart in determining the necessary gauge extension cord

for each of your devices. Round up to the higher amper-

age in the chart to maximize safety.

ENGINE BREAK-IN PROCEDURE

The procedure below should be followed when you re-

ceive 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 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 after 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.

CHANGING FUELS

1. Before changing the fuel source, make sure the generator is turned OFF or running under half-load. Do not change

fuel when the generator is over half-load.

2. If switching from LPG / NG to gasoline, turn off the LPG tank valve or close the NG line and disconnect the LPG

hose or NG hose from the generator. Then turn the fuel valve to ON.

If switching from gasoline to LPG / NG, turn the fuel valve OFF. Then follow the LPG / NG connecting procedure in

sections “FUEL OPTION B: Liquid petroleum gas (LPG)” or “FUEL OPTION C: Natural Gas (NG)”.

3. Check the fuel level of the selected fuel and make sure there is an adequate amount.

4. Turn the fuel selection dial to the desired fuel.

TO STOP THE GENERATOR

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.

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”.

3a. If using LPG / NG, close the LPG valve or NG fuel

line.

3b. If using gasoline, turn the fuel valve to the OFF

(horizontal) position. Let the generator run until the

fuel is used up. Continue on to step 4.

IMPORTANT: Always ensure that the fuel valve and the engine switch are in the OFF or STORAGE position

when the generator is not in use.

USING YOUR GENERATOR

SHUTTING OFF YOUR GENERATOR

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

4. Turn the engine key to the OFF position.

5. Turn the fuel selection knob to STORAGE.

6. Drain the carburetor (See “Draining the Carburetor”).

7. In case you are in a hurry and do not want to wait for the generator to automatically shut down, turn the engine

key to the OFF position and the generator will shut off right away. 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.

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

Proper routine maintenance of the generator will help prolong the life of the machine. Please perform maintenance

checks and operations according to the maintenance schedule below, Table 4. If there are any questions about the

maintenance procedures listed in this manual, please contact customer service at 1-847-429-9263 (M-F 8-5 CST),

or email [email protected].

IMPORTANT GENERATOR MAINTENANCE TIPS:

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

CLEANING THE 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.

DRAINING THE CARBURETOR

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

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 (Fig. 14 - 1)

with a Phillips-head screwdriver (not included) and drain out

any gasoline that has built up inside.

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

NOTE: Make sure to drain your carburetor before storing the

generator for long periods of time.

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.

Fig. 14

CHECKING/ADDING OIL

Check the oil level before each use and every 8 hours of operation.

The oil capacity of the generator engine is 44 ﬂ. oz. 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 an automatic shutoff to protect it from running on low 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. Clean around the oil ﬁll. Remove the dipstick and wipe the it with a clean rag.

3. Insert the dipstick into the oil ﬁll opening without screw-

ing in. Remove the dipstick to check the oil mark (Fig. 15).

Add oil if the oil mark covers less than one half of the dip-

stick.

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

oil. Repeat step 3 until the oil mark reaches the top of the

dipstick (you can see oil coming up the threads of the oil

ﬁll). Do not over ﬁll.

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

Reinstall the oil access cover.

DRAINING/CHANGING OIL

Change the oil according to the Recommended Mainte-

nance Schedule.

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 al-

lows for complete drainage.

To drain the oil from the generator:

1. Place generator on elevated platform. Prepare an ap-

proved gasoline-storage container underneath the oil drain

bolt next to the oil dipstick to catch the oil as it drains.

2. Unscrew the oil drain bolt (Fig. 16 - 1) using the included

10mm/13mm wrench and allow oil to drain from the engine

completely.

3. Reinstall the oil drain bolt and tighten it securely. Wipe

clean any oil spillage.

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.

AIR FILTER MAINTENANCE

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

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

To inspect and clean the air ﬁlter:

1. Remove the air ﬁlter cover (Fig 17 - 1) by undoing the

clasps at the top and bottom of the air ﬁlter cover.

2. Remove the sponge-like air ﬁlter elements from the cas-

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

ﬁlter casing.

3. Check and clean the foam air ﬁlter elements. Good ele-

ments can be washed in soapy water. Dry the elements in

clean cloth (do not twist them). A small amount of oil left

in the elements is normal and necessary for the engine to

work properly.

MAINTENANCE

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

The spark arrestor is located outside the mufﬂer, which gets

very hot during operation. Allow the engine to cool com-

pletely before servicing the spark arrestor. To inspect and

clean the spark arrestor:

1. Remove the four Phillips-head screws holding the spark

arrestor to the mufﬂer (Fig. 18 - 1).

2. Remove the spark arrestor.

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 arres-

tors can be purchased from wenproducts.com (part. no.

To inspect or replace the spark plug:

1. Pull on the spark plug boot to remove it (Fig. 19 - 1). Be

careful not to tear insulation or wire.

2. Remove the spark plug rubber boot and unscrew the

spark plug from the engine using the spark plug wrench

provided.

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 re-

place with a new spark plug.

We recommend replacing with a LG F7RTJC (NGK BP6ET)

spark plug (part no. TF1450X-0310), 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 0.8mm to 1mm (0.031 in. to 0.039 in.) (Fig.

20). Carefully adjust the gap if necessary.

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 spark plug is ½ to ¾ of a turn

(14.5 - 17 ft-lbs, or 20 - 24Nm) after spark plug gasket con-

tacts spark plug hole.

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

SPARK PLUG MAINTENANCE

Refer to Recommended Maintenance Schedule for maintaining the spark plug.

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.

BATTERY MAINTENANCE/STORAGE

The battery (part no. DF1200X-1526) shipped with the

generator has been fully charged. The battery will re-

ceive 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 can still manually start

the generator using the recoil start with gasoline as your

fuel source.

IMPORTANT: If the generator is not used for a long pe-

riod, it is recommended to disconnect the quick connec-

tors to prevent the battery from losing charge. After dis-

connecting the cable, cover the free end with the rubber

covers, or with an insulator such as electrical tape. You

may can also connect the battery to an automatic trickle

charger to keep the battery charged. A smart trickle /

ﬂoat charger is available for purchase at wenproducts.

com (model no. GNA12C).

To reinstall/replace the battery:

1. Disconnect the quick connector ends from each other.

2. Remove the hold down bracket.

3. Remove the quick connectors from the battery termi-

nals.

4. Install the quick connectors on the new battery’s

terminals. Connect the red (positive, +) wire to the red

(positive, +) battery terminal ﬁrst. Then connect the

black (negative, -) wire to the black (negative, -) battery

terminal.

5. Connect the ends of the quick connectors.

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.

CAUTION: Store the emptied gasoline in a suitable

place. Never store fuel for more than 2 months.

MAINTENANCE

NOTE: You can also drain the fuel tank through the car-

buretor. Follow the procedures in “Draining the Carbure-

tor”, and turn the fuel valve ON. It may take a while for

the fuel tank to drain, depending on the amount of fuel

in the tank.

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:

1. Prepare an approved gasoline-storage container to

collect the drained fuel. Place it near the fuel valve.

2. Turn the fuel valve to the OFF position.

3. Locate the fuel line between the fuel valve and back

of control panel. 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.

Turn the fuel valve to ON to start draining the fuel from

the fuel valve opening.

5. Once the fuel is drained, shut OFF the fuel valve.

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

7. Drain the carburetor.

8. Store the emptied gasoline in a suitable place. DO

NOT store ﬂammable materials near the gasoline. Do not

store fuel for more than 3 months.

TRANSPORTING THE GENERATOR

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

1. Tighten the fuel cap and make sure the fuel valve is turned OFF.

2. Make sure the engine switch is in the OFF position.

3. Drain the fuel tank if possible (see “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.

5. Remove the LPG/NG quick connector adapter for transport, and reinstall it on the generator afterwards to prevent

damage.

STORING THE GENERATOR

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

age 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.

For Short Periods (30 to 60 Days):

• Drain the carburetor (see page 29).

• Disconnect the battery quick connectors (see p. 33).

• Add fuel stabilizer:

Follow the suggested portions 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 battery quick connectors (see

page 33) .

• 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”).
