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.

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 11.8 fl. oz (0.35 L).
Fig. 1
To add oil, follow these steps:
1. Place the generator on a level surface. Make sure the engine 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 generator to as-
sist 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 operation. 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. Remove 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. Reinstall 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.

FUEL OPTION A: GASOLINE
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 (4.50 L). Do
not mix oil with gasoline.
To add gasoline, follow these steps:
1. Make sure the generator is shut OFF and on a level sur-
face. 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 gasoline 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.

GENERATOR PREPARATION
STEP 2 - ADD / CHECK FUEL (CONTINUED)
FUEL OPTION B: LIQUID PETROLEUM GAS (LPG)
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. With the LPG tank valve closed, attach the LPG regulator connecting
hose to the valve. Turn the plastic coupling from the hose right (clock-
wise) to tighten hose assembly onto the LPG tank (Fig. 7).
3. Remove the protective rubber cover from the LPG inlet (Fig. 8 - 1)
on the generator panel. Connect the nut on the other end of the regula-
tor connecting hose to the LPG inlet. Tighten the nut using a 19mm or
adjustable wrench (not included).
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.
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.
WARNING! Risk of burns. Contact with liquid contents of cyl-
inder 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.

AUTO FUEL SELECTION
Your generator is equipped with Auto Fuel Selection Technology. What this means is that the generator will auto-
matically select the fuel source (LPG or gasoline) depending on availability. LPG is prioritized; this means that if a
propane tank with enough LPG is connected, the generator will automatically use LPG. If no propane tank is con-
nected, or if there is no LPG remaining in the tank, the generator will use gasoline (if there is gasoline in the fuel
tank). Refer to the chart below for information on how to set up your generator for a particular fuel.
GENERATOR PREPARATION

I want to use gasoline. Closed Run
I want to use LPG. Open Run* or Off
Auto Fuel Selection® chart.*It is ideal to run the generator on LPG with the fuel valve closed (OFF), but if it stays
open (RUN), the generator will still run properly.
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)” table) to ensure that your load(s) will not exceed the rated wattage for a particular fuel. See
also "Switching Fuels" for more information.

Grounding Nut
After completing the above preparation, the generator is ready to be started.
STEP 3 - GROUND THE GENERATOR
To reduce the risk of electric shock and to maximize safety, the genera-
tor should be properly grounded.
Ground the generator by tightening the grounding nut on the front con-
trol 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.
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
DF250i-HA36 for 3000 to 6000 feet above sea level or DF250i-HA68 for 6000 to 8000 feet above sea level. Refer to
the instructions included with your altitude kit for more information about installation.
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 alti-
tudes below 3000 feet.
GENERATOR PREPARATION

during ignition. Otherwise it will be difficult for the engine to start.
3. To maximize safety, check that the generator is properly grounded
(see “GROUND THE GENERATOR” section).
4. Check there is sufficient level of oil in the crankcase. Add oil if neces-
sary (refer to “ADD / CHECK OIL” section).
5. Make sure there is sufficient level of gasoline in the fuel tank. Add
fuel if necessary (refer to “ADD / CHECK FUEL” section). If using LPG,
make sure there is enough propane in the tank, and that the tank and
regulator hose are properly connected.
To start the generator, perform the following steps:
1. Turn the ECO-MODE (Fig. 11 - 1) switch to “OFF” during starting.
2. Open the vacuum relief valve (Fig. 12) on top of fuel cap by rotating
it clockwise to the “ON” position. This will allow fuel to flow.
3. Turn the 3-in-1 dial switch (Fig. 11 - 2) to the “CHOKE” position.
3.1. If starting the generator using LPG, gently pull the recoil starter
handle 1 - 3 times to prime the engine. Then turn the 3-in-1 dial switch
to the "RUN" position. Pull the recoil starter to start the engine.
4. Place one hand on the generator to hold it in place, and pull on the
recoil starter handle slowly until a slight resistance is felt (Fig. 13).
Then pull quickly to start the engine. Return cord gently into the ma-
chine. Never allow the cord to snap back.
5. If engine fails to start, repeat step 4.
NOTE: After repeated failed attempts to start the engine, please consult
the troubleshooting guide before attempting again. If problems persist
please call 1-(800) 232-1195 M-F 8-5 CST.
6. After the engine has started, turn the 3-in-1 switch (Fig. 11 - 2) to the
“RUN” position. The output indicator (green) will light up.
7. Allow the generator to run for several minutes before attempting to
connect any electrical devices. This allows the generator to stabilize its
speed and temperature.

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
Gasoline: 2000W Gasoline: 2500W
LPG: 1800W LPG: 2250W
What this means:
The generator can produce a maximum of
2000W / 1800W on a continuous basis to
supply ongoing power to your electronic de-
vices.
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 2500W / 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 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 2000W / 1800W.
It is recommended to maintain a load at or
below 1800W / 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
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 2500W / 2250W.
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).

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 (2000W gasoline, 1800W LPG) of the genera-
tor, 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. 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 regu-
late the engine speed and automatically adjust its fuel consumption to match the required load. When the electrical
load changes, the generator engine will automatically speed up and slow down as needed. This reduces fuel con-
sumption and noise levels, while extending runtime and engine’s lifespan.
Keep this switch engaged ONLY when the power load requirement is LESS THAN 1500W / 1350W (75% of the rated
watts). Do not engage the Eco-Mode Switch when the total load is more than 1500W / 1350W. The generator engine
must run at full speed to supply power for anything over 1500W / 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 in-
cluded 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.

CO SENSOR INFORMATION
The CO Watchdog carbon monoxide monitoring system (Fig.
14 - 1) measures the accumulation of poisonous CO gas
while the generator is running. If the level of CO gas gets too
high, the CO Watchdog system will automatically shut down
the generator. This system is not a substitute for an indoor
CO alarm.
Whenever the CO Watchdog system shuts down the genera-
tor, the LED on the generator control panel (Fig. 14 - 1) will
blink red for at least 5 minutes after the generator is shut
down. If you notice that the LED is blinking red, vacate the
area immediately. Go to an open, outdoor area. Ventilate
the area around the generator thoroughly before returning.
Let the generator stay shut down for a few minutes before
restarting the engine. This should allow carbon monoxide to
dissipate from the area. If you restart the generator and the
CO Watchdog detects that CO levels are still too high, it will
shut down the generator again. If CO levels are low enough,
the generator will run normally.
1
Ensure that the generator is located in an open outdoor area, with the exhaust pointing away from occupied struc-
tures, and pointing away from the prevailing winds, such that those winds do not blow engine exhaust towards the
sensor module. If anyone experiences dizziness, headaches, nausea, fatigue, or other symptoms of CO poisoning,
get to fresh air immediately and seek the attention of a qualified medical professional. Follow all other directions in
this manual regarding the connection and disconnection of electrical devices when starting or shutting down the
generator.
When starting the generator, the CO Watchdog LED on the panel may flash. This indicates that the system is running
a self-test procedure, and does not indicate a problem.
If the CO Watchdog LED on the panel is yellow, a system error has occurred, or the CO sensor has reached the end
of its life. Contact WEN customer service (1-800-232-1195, M – F 8 – 5 CST, or [email protected])
for assistance.
When operating your generator, please note the following:
• The CO Watchdog does not discriminate in its input; any source of carbon monoxide in the area around the genera-
tor could cause it to activate. If the CO Watchdog LED is blinking red, safety measures should be taken immediately.
• Tampering with, disconnecting, or bypassing the CO sensor could cause hazardous conditions, including but not
necessarily limited to injury or death, and will void your warranty. The generator will not run with the CO sensor
disconnected or bypassed, or if the CO sensor indicates an error.
• The CO sensor has a lifetime of about 7 years, and is capable of monitoring its lifetime. If your generator shows
an error light several years after purchase, it may be time to replace the CO sensor. Contact WEN customer service
for assistance.
NOTE: if the generator is oriented so that the
engine exhaust is blown towards the CO sensor,
the generator may shut down.

OPTION 1A: AUTOMATIC FUEL SHUTOFF (RECOMMENDED – GASOLINE ONLY)
The WEN 2500W 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 stagnant fuel inside of a carburetor.
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 “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 the generator to run at no load for a few minutes to
stabilize internal temperatures.
3. Turn the 3-in-1 switch to the “OFF” position (Fig. 15 - 1).
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 auto-
matically. This helps prevent the carburetor from being clogged
by stale fuel, extending your generator’s lifespan.
SHUTTING OFF YOUR GENERATOR
Fig. 15
CAUTION! Unplugging running devices can cause damage to the generator. Never stop the engine with elec-
trical devices connected and running.
OPTION 1B: AUTOMATIC FUEL SHUTOFF (RECOMMENDED – LPG ONLY)
Although LPG is not prone to degradation the way gasoline is, it is still a good idea to turn the LPG tank OFF before
disconnecting the regulator hose from the generator, so that LPG does not leak from the hose.
1. Turn off all devices prior to unplugging them. Unplugging running devices can cause damage to generator.
2. Allow generator to run at no load for a few minutes to stabilize internal temperatures.
3. Turn the 3-in-1 dial switch to the OFF position (Fig. 15 - 1), if it is not in the OFF position already.
4. Turn the propane tank valve to the OFF position (if the propane regulator hose is connected to the generator). The
engine will continue to run until propane in the carburetor is consumed, which will be nearly immediately. It will then
shut down automatically.
NOTE: If there is gasoline in the fuel tank, and any gasoline has made it into the carburetor for some reason, the
generator may continue to run for a few minutes until the gasoline has been consumed.
WARNING! Allow generator to cool down before touching areas that become hot during use.

SHUTTING OFF THE GENERATOR
CAUTION! Unplugging running devices can cause damage to the generator. Never stop the engine with elec-
trical devices connected and running.
OPTION 2: MANUAL SHUTOFF
In case you are 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 maintenance 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 devices can cause damage to
the generator.
2. Turn the engine switch to the OFF (0) position (Fig. 16 - 1).
Hold the engine switch in the OFF (0) position for about six sec-
onds 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.

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 ser-
vice panel by unscrewing the three Phillips-head screws along the
upper edge.
2. Pull on the spark plug boot (Fig. 21) to remove it. Be careful not to
tear any insulation or wire.
3. Remove the spark plug rubber cover on the top of the generator
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. 22).
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

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. 24).
3. Carefully clean and remove the carbon deposits from the spark
arrestor screen with a wire brush. Replace the spark arrestor if it
is damaged (replacement spark arrestors can be purchased from
wenproducts.com by searching the part no. 56225i-1509).
4. Reinstall the spark arrestor in the muffler and secure it in place
with the screw.

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 openings.
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”.
PRODUCT DISPOSAL
Do not dispose of a used generator or parts with your household waste. This product contains electrical or elec-
tronic components that should be recycled. Please take this product to your local recycling facility for responsible
disposal to minimize its environmental impact.
Do not dispose of used oil or fuel in the trash or down a drain. Please contact your local recycling center or auto
garage to arrange proper oil/fuel disposal.
Please recycle the packaging and electronic components where facilities exist. Please contact your
local auto garage or recycling facility to properly dispose of oil / fuel.
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.
