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.

Lower Limit
Upper Limit
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.
CAUTION: Keep the generator level! Tilting the generator
to assist in filling will cause oil to flow into the wrong ar-
eas of the engine and cause damage.
2. Turn the dipstick (Fig. 1 - 1) counterclockwise until it is
unscrewed from the engine.
3. Using an oil funnel or appropriate dispenser, slowly add
oil into the oil fill, being careful not to overfill the unit. Fill the
crankcase until you can see the oil coming halfway up the oil
fill threads (Fig. 2).
4. Reinstall the oil dipstick and firmly tighten it. Wipe clean
any spilled oil.
For subsequent operation, the oil level should be checked be-
fore each use, or after every 8 hours of operation. The genera-
tor 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 en-
gine is off before adding or checking oil.
2. 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. 3).
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.
4. Wipe clean any oil leaks and firmly tighten the dipstick.
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 alert light (Fig.
4) will turn ON to remind you that the engine oil level is low
and needs to be refilled.
The oil level of the engine should be checked before each start
to ensure that the engine crankcase contains sufficient lubri-
cant.
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 compartment 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
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 4.36 US gallons (16.50 L). Do not mix oil with gasoline.
To add gasoline:
1. Make sure the generator is shut OFF and on a level surface.
Unscrew the fuel cap (Fig. 5 - 1) 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:
Check the fuel gauge (Fig. 5 - 2) on top of the fuel tank. 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 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 (Fig. 6 - 1) 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 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 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.
You can order the kit at wenproducts.com by searching part GN5600-HA. There are two kits - one for altitudes
between 3000 and 6000 feet (part no. GN5600-HA36), and the other for altitudes from 6000 to 8000 feet (part no.
GN5600-HA68). This kit should be installed by a qualified mechanic. Refer to the instructions included with your
altitude kit for more information about installation.
NOTE: The high altitude kit must be installed for operation above 3000 feet.
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.

STARTING YOUR GENERATOR
BEFORE STARTING THE GENERATOR
1. Verify that the generator is outside on a dry, level surface with at least two feet of clearance on all sides.
2. To maximize safety, check that the generator is properly grounded (see "GROUND THE GENERATOR").
3. Check that there is a sufficient level of oil in the crankcase. Add oil if necessary (see "ADD / CHECK OIL").
4. Make sure that there is enough gasoline in the fuel tank. Add fuel if necessary (see "ADD / CHECK FUEL").
5. Make sure all electrical devices are unplugged from the generator during ignition otherwise it will be difficult for
the engine to start.
STARTING THE GENERATOR
1. Turn the fuel valve (Fig. 7 - 1) to the ON position.
2. Turn the choke lever (Fig. 8 - 1) to the CLOSED position.
3. Push the engine switch (Fig. 9) to the ON position.
4. Place one hand on the generator to hold it in place, and pull on
the recoil starter handle (Fig. 8 - 2) slowly until a slight resistance
is felt. Then pull quickly to start the engine. Return cord gently
into the machine. Never allow the cord to snap back.
NOTE: If engine fails to start, repeat step 3.
5. Once the engine starts, turn the choke lever to OPEN.
6. Allow the generator to run for several minutes before attempt-
ing to connect any electrical devices. This allows the generator to
stabilize its speed and temperature.
NOTE: If you have repeated failed attempts to start the engine,
please consult the troubleshooting guide. If problems persist,
please call please call 1-847-429-9263 M-F 8-5 CST.
ENGINE BREAK-IN PROCEDURE
The procedure below should be followed when you receive your
generator in order to prolong the engine's service life. This pro-
cedure helps to seat the piston rings properly in the cylinder, and
will reduce overall wear on the engine.
For the first 8 hours of operation, vary the load, but keep it at or
below 50% of the generator's rated wattage, if possible. If your
generator is equipped with an Eco-mode switch (only applicable
for certain inverter generators), engage Eco-mode periodically
during the first 8 hours. After the first 8 hours, change the oil,
then change it again after the first 25 hours. You may run the
generator at full load after the 8-hour oil change. Refer to the
Recommended Maintenance Schedule in Table 4 for the full main-
tenance schedule.

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
4500W 5600W
What this means:
The generator can produce a maximum of
4500W 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 5600W 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 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 4500W.
It is recommended to maintain a load at or
below 4050W (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 5600W.
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 (4500W) 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 3-phase or 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, one or more circuit breakers
will trip. Unplug all electrical devices, then press the circuit breaker to reset it. If it will not reset, wait a few minutes
for it to cool down. Check the total wattage of the devices and reduce the load if it exceeds the capacity of the gen-
erator. 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, or email [email protected].

SHUTTING OFF 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
Your generator is equipped with automatic fuel shutoff. This feature turns off the flow of fuel, allowing for the gen-
erator 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 fuel valve (Fig. 11 - 1) to the OFF position.
4. The engine will continue to run until the majority of the fuel in
the carburetor is consumed, which takes a few minutes. It will
then shut off automatically. This feature helps to prevent the car-
buretor from being clogged by stale fuel, extending your genera-
tor’s lifespan.
5. Push the engine switch (Fig. 12) to the OFF position.
OPTION 2: MANUAL SHUTOFF
In case you are in a hurry and do not want to wait for the gen-
erator 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 tak-
en, 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. Push the engine switch to the OFF position.
Fig. 11
Fig. 12
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.”
23
MAINTENANCE
Proper routine maintenance of the generator will help prolong the life of the machine. Please perform maintenance
checks and operations according to the schedule in Table 4.

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 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 20.0 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. 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. 13). 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. Do not over fill.
5. Reinstall dipstick and wipe clean any spilled oil with a rag.

MAINTENANCE
DRAINING THE CARBURETOR
We recommend draining the carburetor after every use and before storing the generator. Draining the carburetor
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 engine switch is pressed
to OFF and the fuel valve is in the OFF posi-
tion. This will allow only the fuel left inside the
carburetor will be drained out.
3. The carburetor (Fig. 14 - 1) can be ac-
cessed on the left of the generator, right be-
hind the air filter.
4. Prepare an approved gasoline-storage con-
tainer and a funnel.
5. Open up the carburetor drain screw (Fig.
16 - 2) with a Phillips-head screwdriver and
drain out any gasoline that has built up inside
the carburetor through the included funnel
into the approved gasoline-storage container.
6. Once the fuel has drained, tighten the drain
screw with the screwdriver.
NOTE: Make sure to drain your carburetor be-
fore storing the generator for long periods of
time.

MAINTENANCE
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. Remove the air filter cover (Fig. 15 - 1) by unscrewing the
cover lock knob (Fig. 15 - 2) at the bottom of the air filter
cover.
2. Remove the foam, sponge-like air filter element from the
casing. Wipe excessive oil and any dirt from inside of the air
filter casing.
3. Check the foam, sponge-like air filter element.
a) 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. A
small amount of oil left in the element is normal and neces-
sary for the engine to work properly.
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. 16 - 1).
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.
GN5600-089).
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 impor-
tant 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. Gently pull on the spark plug boot (Fig. 17 - 1) to remove it.
Be careful not to tear any insulation or wire.
2. Use the included spark plug socket (Fig. 18) to unscrew and
then carefully remove the spark plug from the engine.
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.
3. 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 Torch F7TC (NGK BP7ES)
spark plug (part no. GN5600-121), available for purchase at
wenproducts.com.
4. 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.
5. Measure the plug gap with a spark plug gap gauge. The gap
should be 0.028 in. - 0.031 in. (0.7mm - 0.8mm) (Fig. 19).
Carefully adjust the gap if necessary.
6. 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 20 - 22 ft-lbs (27 - 30
Nm).
7. Reinstall the spark plug boot, spark plug rubber cover, and
service panel.

DRAINING / CHANGING OIL
Change the oil according to the Recommended Maintenance Schedule in Table 4. Change the oil MORE OFTEN if
operating under heavy load or high ambient temperatures. It is also necessary to drain the oil from the crankcase if
it has become contaminated with water or dirt. Changing the oil when the engine is warm allows for more-complete
drainage.
To change engine oil:
1. With the help of another person, place the generator on an
elevated platform such as table or workbench.
NOTE: To avoid possible gasoline spills from the carburetor
bowl, drain the carburetor before draining oil.
2. Prepare an approved oil-storage container and place it be-
low the oil drainage bolt (Fig. 20 - 1) to catch oil as it drains.
4. Use a 10mm socket to loosen and remove the oil drainage
bolt, and allow oil to drain from the engine completely.
5. Replace and tighten the oil drainage bolt after the oil has
drained.
NOTE: Never dispose of used engine oil in the trash or down
a drain. Please call a local recycling center or auto garage to
arrange proper oil disposal.

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.
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.
For Short Periods (30 to 60 Days):
• Drain the carburetor.
• Add fuel stabilizer: Follow the suggested por-
tions 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.
