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.

To add oil, follow these steps:
1. Place the generator on a level surface. Make sure the en-
gine is OFF before adding or checking oil.
2. Using a coin, turn the oil access cover screw 1/4 turn
clockwise, then remove the access cover (Fig. 2 - 1) from
the service panel. Then, unscrew the oil dipstick 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
crank case to the upper fill line so you can visually see the oil
coming halfway up the oil fill threads (Fig. 3).
4. Reinstall the oil dipstick and firmly tighten it. Wipe clean
any spilled oil.
5. Reinstall the oil access cover. Using a coin, turn the screw
1/4 turn counterclockwise to secure it in place.
CAUTION! Keep the generator level! Tilting the genera-
tor to assist in filling will cause oil to flow into the engine
areas and will cause damage.

For subsequent operation, the oil level should be checked before each use, or after every 8 hours of op-
eration. The generator is equipped with a low-oil sensor and will NOT start without a sufficient amount
of oil.
Low Oil
Indicator
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. Open the oil access cover. Remove and wipe the dipstick with
a clean rag.
3. Insert the dipstick into the oil fill without screwing it in. Re
-
move the dipstick to check the oil mark (Fig. 4).
If the oil mark covers less than one half of the dipstick, slowly
add oil until the oil mark reaches to the top of the dipstick (or
when you can see the oil coming halfway up the oil fill threads).
4. Wipe clean any oil leaks and firmly tighten the dipstick. Rein
-
stall the oil access cover.
OIL LEVEL SHUTDOWN
To protect the unit from damage, the generator is equipped with
a low-oil-pressure shutoff that will automatically stop the engine
when the oil level is too low. The low oil indication light (yellow)
will turn on to remind you that the engine oil level is low and need
to be refilled.
The oil level of the engine should be checked before each start
to ensure that the engine crankcase contains sufficient lubricant.
TIP: Your WEN generator is compatible with the WEN 55201 Magnetic Oil Dipstick (not included),

GENERATOR PREPARATION
WARNING! RISK OF EXPLOSION. HIGHLY FLAMMABLE: This generator may emit highly flammable and
explosive gasoline vapors, which can cause severe burns or even death, if ignited. A nearby open flame can lead
to explosion even if not directly in contact with gasoline.
• Do not operate near open flame, heat, or any other ignition source. Do not smoke near the generator.
• Always operate on a firm, level surface.
• Always turn generator off before refueling. Allow generator to cool for at least 2 minutes before removing
fuel cap. Loosen cap slowly to relieve pressure in tank.
• Do not overfill fuel tank. Gasoline may expand during operation. Do not fill to the top of the tank. Allow for
expansion. Always check for spilled fuel before operating.
• If fuel spills, move the generator at least 30 feet away from the spill and wipe clean any spilled fuel before
starting the engine.
• Empty fuel tank before storing or transporting the generator.
STEP 2 - ADD / CHECK FUEL
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 1.19 gallons. Do not mix oil
with gasoline.
To add gasoline, follow these steps:
1. Make sure the generator is shut OFF and on a level
surface. Unscrew the fuel cap (Fig. 6) and set it aside.
The fuel cap may be tight and hard to unscrew.
2. Slowly add unleaded gasoline to the fuel tank. Be

do so, gasoline will expand and spill during use, even
with the fuel cap in place.
3. Reinstall fuel cap and wipe clean any spilled gaso-
line with a dry cloth.
To check fuel level
(before every subsequent start):
Before starting the generator, check the fuel gauge
to see if there is sufficient fuel inside the tank. “E”
indicates Empty and “F” indicates Full. Refill the fuel
tank as necessary.
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.

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 eleva-
tions above 8000 feet, the engine may experience a decrease in performance, even with the proper al-
titude 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 56200i-HA36 for 3000 to 6000 feet above sea level or 56200i-HA68 for 6000 to 8000
feet above sea level. 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 damage and affect emissions compliance. Be sure to UNINSTALL the high altitude
kit when operating at altitudes below 3000 feet.

8. Once the engine has started, slowly turn the 3-in-1 switch to the “ON”
position (Figure 4C).
Allow the generator to run for several minutes before attempting to con
-
nect any electrical devices. This allows the generator to stabilize its
speed and temperature.
ECO-MODE IDLE SWITCH
This generator is equipped with an Eco-Mode Idle Control Switch. En-
gaging the switch automatically adjusts the engine to match the load.
When the electrical load changes, the generator engine will automati
-
cally speed up and slow down as needed. This reduces fuel consump-
tion and noise levels. Keep this switch engaged when the power load
requirement is less than 1000W. Do not engage the Idle Control Switch
when the total load is more than 1000W. The generator engine must run
at full speed to supply power for anything over 1000W.

USING YOUR GENERATOR
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
1600W 2000W
What this means:
The generator can produce a maximum of
1600W 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 2000W 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 page 19, Table 2.
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 1600W.
It is recommended to maintain a load at or
below 1440W (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 2000W.
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).

IMPORTANT GENERATOR MAINTENANCE TIPS:
• Drain your carburetor after each use and before storage to prevent it from clogging.
• Do not store the generator with fuel inside the tank for more than 2 months - the fuel will go bad.
• Run the generator for at least 15 minutes every month to maximize its lifespan.
CLEANING THE GENERATOR
Keep the generator clean to prevent improper operation or machine damage from dirt and debris. Inspect all venti-
lation openings on the generator. These openings must be kept clean and unobstructed. If the generator becomes
dirty, use a damp cloth to wipe exterior surfaces. Use a soft bristle brush to loosen dirt and oil and use a vacuum to
pick up loose dirt. Use low pressure air (not to exceed 25 PSI) to blow away dirt.
CAUTION! Never clean the generator when it is running! Never clean with a bucket of water or a hose. Water
can get inside the working parts of the generator and cause corrosion or a short circuit.
NOTE: Failure to properly maintain the generator will void the warranty.

then remove the access cover from the service panel. 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 screwing in.
Remove the dipstick to check the oil mark (Fig. 5). Add oil if the oil
mark covers less than one half of the dipstick.
4. Using a funnel or appropriate dispenser, slowly add more oil.
Repeat step 2 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. Rein
-
stall the oil access cover.
TIP: Your WEN generator is compatible with the WEN 55201 Magnetic Oil Dipstick (not included),
available for purchase at wenproducts.com. The dipstick’s industrial-strength magnetic tip will
collect metal
shavings from your generator’s oil tank to help preserve the engine and extend your
generator’s lifespan.
CLEANING THE GENERATOR
Keep the generator clean to prevent improper operation or machine damage from dirt and debris. In-
spect all ventilation 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.
WARNING: Never clean generator when it is running! Never clean with a bucket of water or a
hose. Water can get inside working parts of the generator and cause corrosion or a short circuit.
CHECKING/ADDING OIL
Check the oil level before each use and every 8 hours of operation (refer to Table 4).
The oil capacity of the generator engine is 11.8 fl. ounces. Add oil when the oil level is low. For
proper type and weight of oil refer to “ADD OIL” portion of the “GENERATOR PREPARATION” sec
-
tion. 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.

SPARK PLUG MAINTENANCE
Refer to Recommended Maintenance Schedule in Table 4 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.
To inspect or replace the spark plug:
1. Using a Phillips-head screwdriver (not included), remove
the service panel by unscrewing the three Phillips-head
screws along the upper edge.
2. Pull on the spark plug boot (Fig. 10) to remove it. Be careful
not to tear any insulation or wire.
3. Remove the spark plug rubber cover on the top of the gen
-
erator next to the fuel gauge. Insert the included spark plug
wrench through the spark plug access hole to unscrew and
then carefully remove the spark plug from the engine (Fig.
11).
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.
4. Visually inspect the spark plug. If it is cracked or chipped,
or if the electrodes are worn or burned, discard it and replace
with a new spark plug.
We recommend replacing with a NGK CR5HS/Torch A5RTC
spark plug (part no. 56200-0806), available for purchase at
wenproducts.com.
5. 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.
6. Measure the plug gap with a spark plug gap gauge. The gap
should be 0.6-0.8 mm (0.024-0.031 in). (Fig. 12). Carefully
adjust the gap if necessary.
7. Screw the spark plug back into the spark plug hole using
the spark plug wrench. Do not over-tighten spark plug. Rec-
ommended tightening of spark plug is ½ to ¾ of a turn (15
ft-lb torque/20.33 Nm) after spark plug gasket contacts spark
plug hole.

months.
To drain the fuel tank and carburetor:
1. Using a Phillips-head screwdriver (not included), remove the service panel by unscrewing the
three Phillips-head screws (Fig. 15) along the upper edge.
2. Locate the carburetor (Fig. 16 - 1) and the transparent drain tube (Fig. 16 - 2) from the carburetor
that extends down through the bottom of the generator.
3. Prepare an approved gasoline-storage container and direct the end of the transparent tube into the
container.
4. Remove the fuel cap and turn the 3-in-1 switch to the “RUN” position. Fuel will start draining from
the carburetor and fuel tank through the drain tube.
NOTE: The draining process may take a few hours, depending on the amount of fuel in your gas tank.
5. Once fuel is completely drained, reinstall the fuel cap and turn the 3-in-1 switch to “OFF” position.
Tighten the drain screw with the screwdriver and reinstall the service panel.
6. Store emptied gasoline in a suitable place. DO NOT store flammable materials near the gasoline.
CAUTION: Store emptied gasoline in a suitable place. Never store fuel for more than 2 months.
SPARK ARRESTOR MAINTENANCE
Inspect and clean the spark arrestor every 100 hours of operation.
The spark arrester is located outside the muffler, which gets very hot during operation. Allow the
engine to cool completely before servicing the spark arrester. To inspect and clean the spark arrester:
1. Remove the screw that secures the spark arrestor to the
muffler.
2. Remove the spark arrestor screen (Fig. 13).
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 by search-
ing the part no. 56225i-1509).

WARNING: Avoid direct sunlight inside a vehicle. If generator is left in an enclosed vehicle
for many hours, the high temp could cause the fuel to vaporize and result in a possible explosion.
WARNING: Store the generator upright in a cool and dry location, away from sources of heat,
open flames, sparks or pilot lights.
TRANSPORTATION & STORAGE
TRANSPORTING THE GENERATOR
To prevent fuel spillage when transporting, be sure to perform the following:
1. Tighten the fuel cap and turn the vacuum relief valve to “OFF”.
2. Set the engine switch to “OFF”.
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 will
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 open-
ings.
Follow the procedures below for properly storing your generator. We highly recommend running your
generator once a month for 15 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. Refer to, “Draining the Carburetor.”
• 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):
• Drain the fuel tank and carburetor. Refer
to, “Draining the Fuel Tank”. Never store
generator with fuel in the tank for more
than two months.
• Change the engine oil. Refer to,
“Changing Oil”.

fessional or commer
cial use. Purchaser has 30 days from the date of purchase to report missing or damaged parts.
SELLER’S SOLE OBLIGA
TION AND YOUR EXCLUSIVE REMEDY under this Limited Warranty and, to the extent per-

chase. Place of Pur
chase must be a direct vendor of Great Lakes Technologies, LLC. Pur

information to make arrangements: your shipping address, phone number, serial number, required part
numbers, and proof of pur
chase. Damaged or defective parts and products may need to be sent to WEN before the
replacements can be shipped out.
Upon
the confirmation of a WEN representative, your product may qualify for repairs and service work. When re-
turning
a product for warranty service, the shipping charges must be prepaid by the purchaser. The product must
be
shipped in its original container (or an equivalent), properly packed to withstand the hazards of shipment. The
product
must be fully insured with a copy of the proof of purchase enclosed. There must also be a description of
the
problem
in order to help our repairs department diagnose and fix the issue. Repairs will be made and the product
will be returned and shipped back to the pur
chaser at no charge for addresses within the contiguous United States.

INCLUDING

BE
LIMITED IN DURATION TO TWO (2) YEARS FROM DATE OF PURCHASE. SOME STATES IN THE U.S. AND
SOME
CANADIAN

ABOVE LIMI
TATION MAY NOT APPLY TO YOU.
IN
NO EVENT SHALL SELLER BE LIABLE FOR ANY INCIDENTAL OR CONSEQUENTIAL DAMAGES (INCLUDING
BUT
NOT
LIMITED TO LIABILITY FOR LOSS OF PROFITS) ARISING FROM THE SALE OR USE OF THIS PRODUCT. SOME
ST
ATES IN THE U.S. AND SOME CANADIAN PROVINCES DO NOT ALLOW THE EXCLUSION OR LIMITATION OF IN-
CIDENT
AL OR CONSEQUENTIAL DAMAGES, SO THE ABOVE LIMITATION OR EXCLUSION MAY NOT APPLY TO YOU.

RIGHTS
WHICH
