GENERATOR SAFETY WARNINGS
DANGER: CARBON MONOXIDE
Using a generator indoors CAN KILL YOU IN MINUTES. Generator exhaust contains carbon monox-
ide (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.

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. The kit can be ordered from wenproducts.com by searching the part
number 56105-HA. Use jet nozzle #68 for altitudes between 3000 to 6000 feet; use jet nozzle #65 for alti-
tudes between 6000 to 8000 feet. 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. The kit should be installed by a qualified mechanic. Refer to the instructions
included with your altitude kit for more information about installation.
CAUTION: Be sure to UNINSTALL the high altitude kit when operating at altitudes below 3000 feet. Engines
with the high-altitude kit installed operated at lower altitudes could cause severe engine damage and affect
emissions compliance.
WARNING: To prevent serious injury from fire, follow the kit installation procedures in a well-ven-
tilated 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

STEP 1: MIXING GASOLINE AND OIL (50:1)
GASOLINE & OIL MIXING RATIO
50:1
• For 1 gallon gasoline, use 2.5 oz oil
• For 2 gallon gasoline, use 5 oz oil
• For 5 gallon gasoline, use 13 oz oil
To mix gasoline and oil:
1. Make sure the fuel container is outside and in a well venti-
lated area.
2. Fill the clean, approved gasoline-storage container with
1/4 of the desired gasoline amount. For example, if mixing 1
gallon of gas, add 1/4-gallon into the container. This allows
sufficient space inside the container for gasoline to mix with
oil. The remaining 3/4-gallon will be added later.
GENERATOR PREPARATION
WARNING: Never store generator with fuel in the fuel tank inside a building with potential sources
of ignition such as hot water tanks, space heaters, clothes dryers, electric motors, etc.
CAUTION: DO NOT mix gasoline and oil directly in the fuel tank; use a separate, approved gasoline-
storage and dispensing container.

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 (800) 232-1195 M-F 8-5 CST for customer service. Fail-
ure to perform these steps properly can damage the generator or shorten its life.
Oil Specifications:
Use one of the following classifications of high-
quality, 2-cycle engine oil:
• NMMA
• TC-W2
• TC-W3
• JASO FB
• FASO FC
3. Measure and add the required amount of oil to the gasoline according to the mixing ratio of 50:1 (e.g. if
mixing 1 gallon of gasoline, add 2.5 oz oil).
4. Tighten the cap on the fuel container.
5. Shake the container vigorously to mix the gasoline and oil.
6. Slowly unscrew the fuel cap, as pressure may have built up inside. Slowly removing the cap allows any
pressure to dissipate. Add the remaining 3/4 portion of fuel. Wipe away any spilled fuel or oil. Tighten the
cap to avoid getting dirt or water into the mixed fuel.
Gasoline Specifications:
• Use UNLEADED gasoline with a maximum of
10% ethanol (E10 gasoline for general use).

USING THE GENERATOR
CALCULATING THE WATTAGE OF YOUR DEVICE(S)
Connect electrical devices running on AC current according to their wattage requirements. Calculate the
running wattage and starting wattage of the device(s) you wish to connect, and MAKE SURE that they are
within the capacity of your generator.
Generator
Wattage
Capacity
Generator Running (Rated) Watts Generator Starting (Surge) Watts
900W 1000W
What this means:
The generator can produce a maximum
of 900W on a continuous basis to supply
the running wattage requirement of your
electronic device(s).
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 motors.
The generator can produce a maximum
wattage of 1000W for a short period of
time (seconds) to cover the extra start-
ing power requirement of 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 Fig. 7.
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 wattage
This wattage should NOT exceed the gen-
erator’s running wattage of 900W.
It is recommended to maintain a load at or
below 810W (90% of the generator’s 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
starting wattage out of the device(s) you
plan to connect
= The total surge (starting) wattage
This wattage should NOT exceed the gen-
erator’s starting wattage of 1000W.
If any of either of the total calculated running watts or starting watts is higher than the
capacity of your generator, adjust the load until both wattage requirements are met.
Otherwise you will overload the generator, and cause damage to the machine.

about the maintenance procedures listed in this manual, please call (800) 232-1195 M-F 8-5 CST or email
techsupport@wenproducts.com.
RECOMMENDED MAINTENANCE SCHEDULE
IMPORTANT GENERATOR MAINTENANCE TIPS:
• Drain your carburetor after each use and before storage (see page 18) 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.
Fig. 9 - Recommended Maintenance Schedule
NOTE: Failure to properly maintain the generator can result in void the warranty.

MAINTENANCE
WARNING: 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.
Keep the generator clean to prevent improper operation or machine damage from dirt and debris. Inspect all
ventilation openings on the generator. These openings must be kept clean and unobstructed. If the genera-
tor 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.
CLEANING THE GENERATOR
Recommended to drain after every use, and before storage.
Draining the carburetor is recommended to prevent the fuel from clogging up the carburetor. A clogged car-
buretor can prevent the generator from starting. Remove the front panel of the generator. The choke lever is
located on top of the carburetor.
DRAINING THE CARBURETOR
1. Open up the carburetor drain screw with a Phillips screwdriver (not
included) and drain out any gasoline that has built up inside the car-
buretor into an approved gasoline-storage container.
2. Once the fuel has drained, tighten the drain screw with the screw-
driver.
NOTE: Make sure to drain your carburetor before storing the generator
for long periods of time.

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.
Check every 50 hours of operation (refer to Fig. 9 - Recommended Maintenance Schedule).
Routine maintenance of the air filter helps maintain proper airflow to the carburetor. The air filter should be
free of excessive dirt.
AIR FILTER MAINTENANCE
To inspect and clean the air filter:
1. Undo the two screws (Fig. 11 - 1) holding the air cleaner
cover in place using a Phillips head screwdriver (not included).
2. Wear gloves; air filter is oily. Remove the air filter element.
Wipe any dirt from inside of the air filter casing.
3. Wash the element in warm soapy water. Squeeze it thor-
oughly dry in a clean cloth.
4. If the air filter element has been damaged, replace with a
new one. Replacement air filters can be ordered from wen-
MAINTENANCE
products.com by searching the Part No. 56105-079.
5. Saturate the element in clean engine oil and squeeze off excess oil in a clean absorbent cloth. Drip the
sponge-like element in clean engine oil (meeting the requirements specified on page 10), squeeze out extra
oil and reinsert into the casing. NOTE: A small amount of oil in the element is necessary for the engine to
work properly.
6. Attach the air cleaner cover with the 2 screws.
Inspect and clean the spark arrestor every 200 hours of operation (refer to Maintenance Schedule).
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:
SPARK ARRESTOR MAINTENANCE
1. Remove the screw that secures the spark arrestor to the muffler.
2. Remove the spark arrestor screen (Fig. 12 - 1).
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.
4. Reinstall the spark arrestor in the muffler and secure it in place
with the screw.

Refer to Recommended Maintenance Schedule in Fig. 9 for maintaining the spark plug.
The spark plug is important for proper engine operation. Check the spark plug regularly for proper engine
operation. A good spark plug should be intact, free of deposits, and properly gapped.
SPARK PLUG MAINTENANCE
MAINTENANCE
To inspect or replace the spark plug:
1. Pull on the spark plug boot to remove it. Be careful not to tear
any insulation or wire.
2. Use the included spark plug wrench to unscrew and carefully
remove the spark plug from the engine.
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 NGK BP5ES spark plug (Part No.
56105-069), 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 0.7 to 0.8 mm (0.028-0.031 in.) (Fig. 14). Carefully
adjust the gap if necessary.
6. Screw the spark plug back into the spark plug hole by hand.
After the spark plug is properly seated, use the spark plug
wrench to tighten it.
Do not over-tighten the spark plug.
NOTE: The spark plug torque is 9 - 12 N.m ( 7 - 8 ft.lb). The
spark plug should be tightened 1/2 to 3/4 turn after spark plug
gasket contacts spark plug hole.
7. Reinstall the spark plug boot over the spark plug.
Recommended Spark Plug:

Clean the fuel tank each year, or before storing the generator for extended periods of time.
To drain the fuel tank:
DRAINING THE FUEL TANK
CAUTION: Do not store fuel for more than 2 months. Fuel stored for longer than 2 months can go bad.
MAINTENANCE
1. Turn the fuel valve to the OFF (horizontal) position.
2. Remove the four bolts holding the fuel tank onto the gen-
erator frame (Fig. 16 - 1).
3. Lift the fuel tank and rotate it so as to clear the tank from
the generator frame. The fuel valve should be visible. Place a
approved gasoline-storage container under the fuel valve to
catch fuel when the fuel line is disconnected.
4. Using a pair of pliers, slide the fuel line clamp off the fuel
valve so the line can be disconnected.
5. Collect any fuel left in the fuel line going to the carburetor.
6. Place the fuel tank over the fuel collecting container and
open the fuel valve. The fuel should drain from the tank.
7. Reconnect the fuel line and reattach the fuel tank with the
four bolts.
8. Start and run the engine until fuel runs out.
9. Store the emptied fuel in a suitable place.

WARNING: Never store generator with fuel in the fuel tank inside a building with potential sources
of ignition such as hot water tanks, space heaters, clothes dryers, electric motors, etc.
Do not dispose of used generator or parts with your household waste. This product contains electrical or
electronic 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.
PRODUCT DISPOSAL
To prevent fuel spillage when transporting, be sure to perform the following:
1. Tighten the fuel cap.
2. Set the engine switch to OFF.
3. Drain the fuel tank if possible (see “DRAINING THE FUEL TANK”
page 21
).
4. Keep the generator upright. Never place the generator on its side or upside down - doing so will make
it difficult to start.
TRANSPORTING THE GENERATOR
WARNING: Avoid direct sunlight inside a vehicle. If the generator is left in an enclosed vehicle for
many hours, the high temperature could cause the fuel to vaporize and result in a possible explosion.
22
TRANSPORTATION & STORAGE
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 gen-
erator once a month for 15 to 30 minutes. Plug in a small load in to ensure there is proper power output.
STORING THE GENERATOR
For Short Periods (30 to 60 Days):
• Drain the carburetor (see page 18).
• Gasoline stored over 30 days can start to go bad and
damage fuel system components.
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 carburetor (see page 18).
• Drain the fuel tank (see “
DRAINING THE
FUEL TANK”
on page 21). Never store with
fuel in the tank for more than two months.
WARNING: Store the generator upright in a cool and dry location, away from sources of heat, open
flames, sparks or pilot lights.
