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.

ASSEMBLY & ADJUSTMENTS
HIGH ALTITUDE OPERATION ABOVE 3000 FEET
The fuel system on this generator may be affected by opera-
tion 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 the high
altitude kit at elevations above 3000 feet may increase the
engine’s emissions and decrease both fuel economy and
performance.
NOTE: If you plan to only use propane at high altitudes, a
high-altitude kit is not required. High-altitude kits are only
required if you plan to use gasoline at high altitudes.
INSTALLING THE HIGH ALTITUDE KIT
This kit should be installed by a qualified mechanic. Con-
tact customer service at 1-800-232-1195 (M-F 8-5 CST),
or email [email protected] for information

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 1-800-232-1195 (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.

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 (16.0L). 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
FUEL OPTION A: GASOLINE

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 gas tank. See above section, "To Add Gasoline".

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.
STEP 3 - CONNECT THE BATTERY
CAUTION! Always position the LPG cylinder so the connection between the tank and LPG inlet won’t cause
sharp bends or kinks in the hose.
GENERATOR PREPARATION
FUEL OPTION B: LIQUID PETROLEUM GAS (LPG) (CONT.)
4. Turn the LPG tank valve ON (Fig. 9) and check for leaks by spraying
soapy water to check connections. If bubbles appear, become larger
in size, or increase in number, a leak exists. This MUST be corrected
before using generator. Contact WEN customer service at 1-800-232-
1195, M-F 8-5 CST, or email [email protected] for as-
sistance.
NOTE: You can use Teflon (or other tape) to secure the connection of
the LPG hose to your generator.
NOTE: If you would like to purchase other accessories for your dual-
fuel generator, consult your local dealer of propane and propane ac-
cessories, I tell you what.
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.

WARNING! Use only genuine WEN batteries with your generator (part no. 56380i-1304). Use of other bat-
teries may induce premature product failure and could pose a safety risk.
NOTE: Make sure the generator can handle the load(s) you plan to connect. The generator can provide more power
when running on gasoline than on LPG. Consult the specifications table on p. 3, as well as the “Calculating the Watt-
age of Your Device(s)” chart to ensure that your load(s) will not exceed the rated wattage for a particular fuel. See
also "Switching Fuels" section for more information.

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.)
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.).
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 1-800-232-1195 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.
GENERATOR PREPARATION
To connect the battery:
1. Remove the black battery bracket by removing the two
bolts that hold the battery bracket in place. Pull out the bat-
tery for easier access.
2. Pull back the protective cover from the red (+) lead near
the battery.
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. 10). 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.
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
1-800-232-1195 (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.
