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.

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 gen-
erator for the first time. The oil capacity of the engine crankcase is 11.8 fl. oz (0.35 L).
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.
• 30W Engine Oil
Temperatures above 40°F
• 10W-30 Engine Oil
Temperatures between 0°F - 40°F
• Synthetic 5W-30 Engine Oil
All temperature ranges
ENGINE OIL RECOMMENDATIONS
Select good quality detergent oil bearing the American Petroleum Institute (API) service classifications

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),
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.

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
careful not to overfill.
NOTE: Do not fill the fuel tank to the very top. If you
do so, gasoline will expand and spill during use, even
with the fuel cap in place.
3. Reinstall fuel cap and wipe clean any spilled 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.

STEP 3 - 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. 7) against a grounding wire. A gen
-
erally 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 gen
-
erator.
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 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.

GENERATOR RUNNING (RATED) WATTS GENERATOR STARTING (SURGE) WATTS
1800W 2250W
What this means:
The generator can produce a maximum of
1800W 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 2250W 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 18, 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 1800W.
It is recommended to maintain a load at or
below 1620W (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

CONNECTING ELECTRICAL DEVICES
When the rated wattage requirement of each electrical device has been determined, add these numbers to find the
total rated wattage needed. If this number exceeds the rated wattage (1800W) of the generator, DO NOT connect all
these devices. Select a combination of electrical devices with a total rated wattage lower than or equal to the rated
wattage of the generator.
CAUTION! Become familiar with the markings on the control panel (Fig. 11) before connecting electrical
devices. Do not connect 50Hz loads to the generator.
1. Before connecting electrical devices, allow the generator to run for a few minutes to stabilize the speed and volt-
age output.
2. Make sure that all devices are turned off. Start plugging in each electric device, from the highest wattage to the
lowest. Check the power indicator light (green) to ensure the generator is producing power.
3. Do not overload the generator or individual panel receptacles. If an overload occurs, the overload indication light
(red) will activate. If it is flashing, turn off and unplug one load. If it is solid (not flashing), the generator will cut
off power to protect itself. Unplug all electrical devices and then press the reset button to reset the entire circuit,
or press the circuit breaker to reset the DC circuit. Check the total wattage of the devices and reduce the load if it
exceeds the capacity of the generator. Then, plug the loads back in one by one.
NOTE: If the reset button or circuit breaker does not reset, wait several minutes and try again. If problem still per-
sists, please call 1-(800) 232-1195 M-F 8-5 CST.
NOTE: The NEMA 5-20 receptacles are capable of connecting devices up to 20A only when two generators are
parallel connected. When operating a single generator, do not exceed 15A (1800 running watts) on this receptacle.

ECO-MODE SWITCH
This generator is equipped with an Eco-Mode Idle Control Switch. Engaging this switch allows the
system to regulate the engine speed and automatically adjust its fuel consumption to match the re
-
quired load. When the electrical load changes, the generator engine will automatically speed up and
slow down as needed. This reduces fuel consumption and noise levels, while extending runtime and
engine’s lifespan.
Keep this switch engaged ONLY when the power load requirement is LESS THAN 1350W (75% of the
rated watts). Do not engage the Eco-Mode Switch when the total load is more than 1350W. The genera
-
tor engine must run at full speed to supply power for anything over 1350W.
PARALLEL OPERATION
The parallel connection ports allow you to connect two WEN generators to increase the total available
electrical power. The WEN Parallel Connection Kit can be purchased from wenproducts.com. Follow
the instructions included with your parallel connection kit for proper installation and operation.
IN CASE OF OVERLOAD
If your generator becomes overloaded from too much drawn wattage, the overload indicator (red) on
the control panel will light up, and the overload reset button on your control panel may activate and cut
off the output. When an overload occurs, reduce the load by turning off and unplugging your electronic
device(s), then press the reset button to reset your generator. If no power is produced after resetting,
restart your generator.
• 4% to 10% over rated watts: overload light will flash to indicate overload
• 10% to 18% over rated watts: overload light will stay on for 16 seconds, output will be cut off.
• More than 18% over rated watts: overload light will stay on for 3 seconds, output will be cut off.

WARNING! Generator should only be connected to electrical devices, either directly or with an extension
cord. NEVER CONNECT TO A BUILDING ELECTRICAL SYSTEM without a qualified electrician and connected to
a transfer switch as a separately derived system. Such connections must comply with local electrical laws and
codes. Failure to comply can create a back-feed, which may result in serious injury or death to utility workers.
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.
USING YOUR GENERATOR
21
WARNING: Allow generator to cool down before touching areas that become hot during use.
OPTION 1: FUEL SHUT OFF (RECOMMENDED)
The WEN 2250W Inverter Generator is equipped with automatic fuel shutoff. This feature turns off the
flow of fuel, allowing for the generator to use up the remaining fuel from the carburetor before turning
off. This prolongs the lifespan of the generator by preventing build-up and blockages caused by stag-
nant fuel inside of a carburetor.
CAUTION: Unplugging running devices can cause damage to the generator. Never stop the
engine with electrical devices connected and running.
CAUTION: Allowing gasoline to sit in the fuel tank for long periods of time can make it difficult
to start the generator in the future. Never store the generator for extended periods of time (over 2
months) with fuel in the fuel tank. Refer to “TRANSPORTATION & STORAGE”.
1. Turn off all electrical devices prior to unplugging them
from the generator. Unplugging running devices can
cause damage to the generator.
2. Allow generator to run at no load for a few minutes to
stabilize internal temperatures.
3. Turn the engine switch to the “OFF” position (Fig. 12).
4. Close the vacuum relief valve on the top of the fuel cap
by rotating it counterclockwise to the “OFF” position.
5. The engine will continue to run until the majority of the
fuel in the carburetor is consumed. The engine will then
shut off automatically. This helps prevent the carburetor
from being clogged by stale fuel, extending your genera
-
tor’s lifespan.
OPTION 2: MANUAL SHUT OFF
In case you need to refuel or move your generator in a hurry, and do not want to wait for the generator
to automatically shut down, the manual shutoff feature is available. However, this method will leave
stagnant fuel in the carburetor, possibly causing blockages, a shortened lifespan, and other mainte
-
nance issues. If this approach is frequently taken, make sure to drain your carburetor before any long
storage periods.
1. Turn off all electrical devices prior to unplugging them from the generator. Unplugging running de
-
vices can cause damage to the generator.
2. Press the “MANUAL SHUT OFF” switch (Fig. 13 - 1) and hold it down in the “OFF” position for about
6 seconds until the engine shuts off.

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.

2. Using a coin, turn the oil access cover screw 1/4 turn clockwise,
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. 14). 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.
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!

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”.
