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
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. 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 suf-
ficient lubricant.
TIP: Your WEN generator is compatible with the WEN
55201 Magnetic Oil Dipstick (not included), available for

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.

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.

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).
