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.

areas of the engine and cause damage.
2. Turn the oil access cover knob to the unlocked position,
and remove the access cover from the side panel. Unscrew
the oil dipstick from the engine (Fig. 2).
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 (Fig. 3).
4. Reinstall the oil dipstick and firmly tighten it. Wipe clean
any spilled oil.
5. Reinstall the oil access cover. Turn the oil access cover
knob to the locked position to secure the cover in place.

GENERATOR PREPARATION
STEP 1 - ADD / CHECK OIL (CONTINUED)
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.
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 yellow low oil
indication light (Fig. 5) 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 suf-
ficient 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 in-
dustrial-strength magnetic tip will collect metal shav-
ings from your generator’s oil compartment to help
preserve the engine and extend your generator’s lifes-
pan.

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
Use ONLY 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 2.2 US gallons (8.50 L). Do not mix oil with gasoline.
To add gasoline:
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:
During operation, the fuel level will be displayed by the in-
dicator lights on the right side of the multi-meter. If the fuel
level is low, refill the fuel tank before starting your generator
for the next time.
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 5 - 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 (Fig. 7) on the
front control panel against a grounding wire. A generally acceptable
grounding wire is a No. 12 AWG (American Wire Gauge) stranded cop-
per 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 electri-
cian to check the area codes.
WARNING! Failure to properly ground the generator increases your risk of electric shock.
HIGH ALTITUDE OPERATION ABOVE 3000 FEET
The fuel system on this generator may be affected by operation at high altitudes. Proper operation can be ensured
by installing an altitude kit at altitudes higher than 3000 feet above sea level. At elevations above 8000 feet, the en-
gine 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.
You can order the kit at wenproducts.com by searching part 56450i-HA. There are two kits - one for altitudes be-
tween 3000 and 6000 feet (56450i-HA36), and the other for altitudes from 6000 to 8000 feet (56450i-HA68). This
kit should be installed by a qualified mechanic. Refer to the instructions included with your altitude kit for more
information about installation
WARNING! To prevent serious injury from fire, follow the kit installation procedures in a well-ventilated
area away from ignition sources. If the engine is hot from use, shut the engine off and wait for it to cool before
proceeding. Do not smoke near the generator. Warranty will be void if adjustments are not made for high altitude
use.
CAUTION: Engines with the high-altitude kit installed operated at lower altitudes could cause severe engine dam-
age and affect emissions compliance. Be sure to uninstall the high altitude kit when operating at altitudes below
3000 feet.
After completing the above preparation, the generator is ready to be started.

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 4500W for a short period of time
(seconds) to cover the extra starting power
required by your electronic devices.

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 20, 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 3500W.
It is recommended to maintain a load at or
below 3150W (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 4500W.
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).

USING YOUR GENERATOR
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 (3500W) 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 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 1-847-429-9263 M-F 8-5 CST.

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.
22
USING YOUR GENERATOR
ECO-MODE SWITCH
This generator is equipped with an Eco-Mode Idle Control Switch
(Fig. 11). Engaging this switch allows the system to regulate 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 consumption and noise levels, while
extending runtime and engine’s lifespan.
Keep this switch engaged ONLY when the power load requirement is less than 2625W (75% of the rated watts). Do
not engage the Eco-Mode Switch when the total load is more than 2625W. The generator engine must run at full
speed to supply power for anything over 2625W.
PARALLEL OPERATION
The parallel connection ports (Fig. 12) 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. Follow the instructions below when an overload occurs:
• When you’re close to overloading the generator, the overload
light will start to flash. Reduce the load by turning off and dis-
connecting your electronic device(s) until the overload light turns
off. Then you may continue to operate your generator.
• When you’ve overloaded the generator, the overload light will stay on and the reset button (Fig. 13) will activate
to cut off the output in 3 to 16 seconds, depending on the load. Reduce the load by turning off and disconnecting
your electrical device(s) until the overload light turns off. Wait about five minutes and then press the activated reset
button to reset the circuit. If no power is produced after resetting, turn off and disconnect all electrical devices and
restart your generator.
CIRCUIT BREAKERS
In addition to the reset button that protects the generator’s main
circuit, the circuit breakers (Fig. 14) protect the individual AC and
DC circuits. The 20-amp AC circuit breaker will activate when the
NEMA 5-20 outlets exceed 20A. The 10-amp DC circuit breaker
will activate when the DC 12V and USB outlets exceed 10A. When
the circuit breaker activates, turn off and disconnect the device
from its respective outlet, and press the circuit breaker to reset.

USING YOUR GENERATOR
CO SENSOR INFORMATION
The CO Watchdog carbon monoxide monitoring system (Fig.
15 - 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. 15 - 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 (1-847-429-9263, 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.

MULTI-METER
The multi-meter on your generator switches between voltage (e.g. 120.1), frequency (e.g. 60.0H), and runtime (e.g.
12.3) every 5 seconds. When you first use the generator, the meter will count runtime, but will not store runtime
until the generator is run for longer than 2 hours at a time. Once the generator has been run for more than 2 hours
at a time, the meter will track runtime normally. For an example, as well as more explanation, please refer to Table

STOPPING YOUR GENERATOR
CAUTION! Unplugging running devices can cause damage to the generator. Never stop the engine with elec-
trical devices connected and running.
OPTION 1: AUTOMATIC FUEL SHUTOFF (RECOMMENDED)
The WEN 4500W 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.
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. 16).
4. The engine will continue to run until the majority of the fuel in
the carburetor is consumed. It will then shut off automatically.
This feature helps to prevent the carburetor from being clogged
by stale fuel, extending your generator’s lifespan.
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. Press the “MANUAL SHUTOFF” switch and hold it down in the “OFF” position for about 6 seconds until the engine
shuts off.
WARNING! Allow the generator to cool down before touching areas that become hot during use.
CAUTION: Allowing gasoline to sit in the fuel tank for long periods of time can make it difficult to start the gen-
erator in the future. Never store the generator for extended periods of time (over 2 months) with fuel in the fuel
tank. Refer to “Storing the Generator.”

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 20 minutes every month to charge the battery and maximize 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.

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 18.6 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” section. This is a critical step for proper engine
starting. The generator is equipped with a with low-oil shut down to protect it from running without oil.
To check the oil level and add oil:
1. Make sure the generator is on a level surface. Do not tilt the generator, as oil will flow into engine areas and cause
damage. Keep generator level!
2. Turn the oil access cover knob to the unlocked position, and remove the ac-
cess cover from the front panel. Clean around the oil fill. Remove the dipstick
and wipe 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. 17). 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 the
step above until the oil mark reaches the top of the dipstick (you can see oil
coming up the threads of the oil fill). Do not over fill.
5. Reinstall dipstick and wipe clean any spilled oil with a rag. Reinstall the oil
access cover.
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 pan to help preserve the engine and extend your generator’s lifespan.

DRAINING THE CARBURETOR
We recommend draining the carburetor after every use and before storing the generator. (If the generator is shut
off using the AUTO OFF/FUEL OFF, it is only necessary to drain it before periods of long storage.) Draining the car-
buretor can prevent the fuel from clogging up the carburetor; a clogged carburetor can prevent the generator from
starting.
1. With the help of another person, place the
generator on an elevated platform such as a
table or desk.
2. Make sure that the 3-in-1 dial switch to
turned to “AUTO OFF”. At this position, the
fuel valve is turned OFF so that only the fuel
left inside the carburetor will be drained out.
3. Using a Phillips-head screwdriver, unscrew
the top two screws (Fig. 18 - 1) and remove
the service panel on the opposite side of the
recoil starter.
4. The carburetor can be accessed between
the engine and the air filter (Fig. 18). Locate
the transparent tube from the carburetor (Fig.
21) that extends down through the base plate
of the generator.
5. Prepare an approved gasoline-storage con-
tainer and direct the end of the drain tube into
the container.
6. Open up the carburetor drain screw (Fig. 19) with a flat-head
screwdriver and drain out any gasoline that has built up inside
the carburetor through the drain tube into the approved gaso-
line-storage container.
7. Once the fuel has drained, tighten the drain screw with the
screwdriver.
NOTE: Make sure to drain your carburetor before storing the
generator for long periods of time.
8. Reinstall the service panel.

AIR FILTER MAINTENANCE
Check every 50 hours of operation (refer to Table 4 - Recommended Maintenance Schedule).
Routine maintenance of the air filter helps maintain proper airflow to the carburetor. Occasionally check that the air
cleaner is free of excessive dirt.
To inspect and clean the air filter:
1. Using a Phillips-head screwdriver, unscrew the top two
screws (Fig. 18 - 1) and remove the service panel on the op-
posite side of the recoil starter.
2. Take the cover off of the air cleaner (Fig. 20). Remove the
sponge-like air filter element from the casing. Wipe excessive
oil and any dirt from inside of the air filter casing.
3. Check and clean the foam air filter element. Good elements
can be washed in soapy water. Dry the element in clean cloth
(do not twist it). Add a few drops of engine oil to the air filter
element and spread it evenly.
If the air filter element has been damaged, replace it with a new one. Replacement air filters can be ordered from
wenproducts.com by searching part no. 56380i-1001B.1.
4. Reinstall the air cleaner element, air cleaner cover and service panel.
WARNING! Running the engine with a dirty, damaged or missing air filter element can result in danger to the
operator and cause the engine to wear out prematurely.
SPARK ARRESTOR MAINTENANCE
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 two Phillips-head screws that secure the
spark arrestor to the muffler (Fig. 21).
2. Remove the spark arrestor screen.
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.
56380i-1115).
4. Reinstall the spark arrestor in the muffler and secure it in
place with the screws.

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, unscrew the top two
screws (Fig. 20 - 1) and remove the service panel on the op-
posite side of the recoil starter.
2. Gently pull on the spark plug boot (Fig. 22) to remove it. Be
careful not to tear any insulation or wire.
3. Use the included spark plug wrench to unscrew and then
carefully remove the spark plug from the engine (Fig. 23).
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 BPR6ES/Torch F6RTC
spark plug (part no. 56310i-0104), 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 0.7 - 0.8 mm (0.028 - 0.031 in) (Fig. 24). 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.

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 20 to 30 minutes. Plug in a small load in to ensure there is proper power output.
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.
For Short Periods (30 to 60 Days):
• Drain the carburetor. Refer to page 27, “Draining the
Carburetor.”
• Disconnect the negative lead from the battery.
• Add fuel stabilizer: Follow the suggested portions and
instructions of your preferred stabilizer. Run the engine for
15 to 20 minutes, allowing the fuel stabilizer to mix with the
gasoline and circulate through the carburetor, and then top
off with fuel. Filling the fuel tank full reduces the amount of
air in the tank and helps fight deterioration of fuel.
For Extended Periods (Over 60 Days):
• Disconnect the negative lead from the
battery.
• Drain the fuel tank and carburetor (see
“Draining the Fuel Tank”). Never store
generator with fuel in the tank for more
than two months.
• Change the engine oil (see “CHANGING
OIL”).
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.
