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.
WARNING: The exhaust from this product contains chemicals known to the State of Califor-
nia to cause cancer, birth defects, or other reproductive harm.
WARNING: 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 it isn’t directly in contact with gasoline.
SAFETY INFORMATION
1) Do not operate near open flame.
2) Do not smoke near generator.
3) Always operate on a firm, level surface.
4) Always turn generator off before refueling. Allow
generator to cool for at least 2 minutes before re-
moving fuel cap. Loosen cap slowly to relieve pres-
sure in tank.
5) Do not overfill fuel tank. Gasoline may expand
during operation. Do not fill to the top of the tank.
Allow for expansion.
6) Always check for spilled fuel before operating.
7) Empty fuel tank before storing or transporting the
generator.
8) Do not use in rainy conditions.
9) ALWAYS ground the generator before using it (see
the “Ground the Generator” portion of the “Genera-
tor Preparation” section).
10) Generator should only be plugged into electri-
cal devices, either directly or with an extension cord.
NEVER connect to a building’s electrical system with-
out a qualified electrician. 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.
11) Use a ground fault circuit interrupter (GFCI) in
highly conductive areas such as metal decking or steel
work. GFCIs are available in-line with some extension
cords.
12) Do not touch bare wires or receptacles (outlets).
13) Do not allow children or non-qualified persons to
operate the generator.

USING THE GENERATOR FOR THE FIRST TIME
CAUTION: The following section describes the necessary steps to prepare the generator for use. If after reading
this section, you are unsure about how to perform any of the steps please call (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 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 13.5 fl. ounces. For general use (above 40° F), we recom-
mend 30W, 4-stroke engine oil. 10W-30 synthetic oil is also acceptable.
88
Oil Dipstick
GENERATOR PREPARATION
Fig. 2 - Oil Fill Opening, Dipstick and Oil Level
To add oil, follow these steps:
Note: make sure the generator is on a level
surface. Tilting the generator to assist in
filling will cause oil to flow into the engine
areas and will cause damage. Keep the
generator level!
1. Remove the dipstick from the engine
(Fig. 2).
2. Add oil slowly, being careful not to
overfill the unit. We highly recommend
using a funnel if you have one available.
Fill the crank case to the upper fill line so
the oil lands about halfway up the dipstick
threads (Fig. 2).
3. To check the oil level, wipe the dipstick
with a clean rag. Insert the dipstick into
the oil fill opening without screwing it in.
Remove the dipstick to check the oil mark.
Fig. 1 - Engine Oil Temperature Recommendation
CAUTION: Air cooled engines run hotter than automotive
engines. The use of non-synthetic multi-viscosity oils (5W-30,
10W-30, etc.) in temperatures above 40° F will result in higher
than normal oil consumption. When using a multi-viscosity oil,
check the oil level more frequently than you would otherwise.
ENGINE OIL RECOMMENDATIONS
Select good quality detergent oil bearing the American Petro-
leum Institute (API) service classifications SJ, SL, or SM (syn-
thetic oils may be used). Use the ASE viscosity grade of oil from
the following chart (Fig. 1) that matches the starting temperature
anticipated before the next oil changes.
Oil
Dipstick
Lower Level
Fill Line
Upper Level
Fill Line
4. Slowly add more oil and repeat step 4
until the oil mark reaches to the top of
the dipstick, or just when the oil is visibly
coming up the bottom threads (Fig. 2). Do
not overfill the crankcase. The generator is
equipped with a low-oil sensor and will not
start without a sufficient amount of oil.
5. Check for oil leaks and firmly tighten the
dipstick.
NOTE: After completing the above preparation, the generator is ready to be started.
Step 2 - ADD GASOLINE
Use fresh (within 30 days from purchase), lead-free gasoline
with a minimum of 87 octane rating. Do not mix oil with gaso-
line.
To add gasoline, follow these steps:
1. Make sure the generator is on a level surface.
2. Unscrew fuel cap and set aside.
NOTE: The fuel cap may be tight and hard to unscrew.
WARNING: Failure to properly ground the generator increases your risk of electric
shock.
3. Slowly add unleaded gasoline to the fuel tank. Be careful not to over-
fill. The capacity of the fuel tank is 1.1 gallons.
NOTE: Do not fill the fuel tank to the very top. Gasoline will expand and
spill over during use even with the fuel cap in place.
4. Reinstall fuel cap and wipe clean any spilled gasoline with a dry cloth.
STEP 3 - GROUND THE GENERATOR

Grounding Nut
GENERATOR PREPARATION
Fig. 3
WARNING: 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.
IMPORTANT:
• Never use an oil/gasoline mixture.
• Never use old gasoline.
• Avoid getting dirt or water into the fuel
tank.
• Gasoline can age in the tank and make
starting difficult. Never store generator
for extended periods of time with fuel
in the tank.
Ground the generator by tightening the grounding nut on the front control panel against a grounding wire (Fig. 3). A
generally acceptable grounding wire is a No. 12 AWG (American Wire Gauge) stranded copper wire. This ground-
ing 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.
Grounding codes can vary by location. Contact a local electrician to check the area codes.

cause damage to the generator.
2. Turn the engine switch to the “OFF” position.
CAUTION: Allowing gasoline to sit in the fuel tank for long periods of time can make it diffi-
cult to start the generator in the future. Never store the generator for extended periods of time
(over 2 months) with fuel in the fuel tank. Refer to Generator Storage Section.
WARNING: Allow the generator to cool for several minutes before touching areas
that become hot during use.
If this is not the first time using the generator, the user should take the following steps to prepare it for operation.
Step 1 - CHECK THE OIL
Oil consumption is normal during generator use. The generator is equipped with a low oil pressure shutoff to
protect it from damage. The oil level of the engine should be checked before each use to ensure that the engine
crankcase contains sufficient lubricant.
To check or add oil, follow these steps:
1. Make sure the generator is on a level surface.
2. Remove the oil filler/dipstick cap and check the oil level.
3. If oil level is below the second thread from the lip of the oil fill opening, slowly add oil until the engine crank-
case is filled.
4. Reinstall and tighten oil cap before starting the engine.
Step 2 - CHECK THE FUEL LEVEL
Before starting the generator, check to see that there is sufficient gasoline in the fuel tank. Add additional gasoline
as necessary but leave sufficient room in the tank for expansion.
SUBSEQUENT STARTING OF THE GENERATOR
IMPORTANT:
• Use only UNLEADED gasoline.
• Do not use old gasoline.
• Never use an oil/gasoline mixture.
• Avoid getting dirt or water into the fuel tank.
IMPORTANT: At this point the user should be familiar with the procedures described in
the sections titled “Starting the Generator” and “Generator Preparation.” If the user has
not yet read these sections, go back and read them now.
13
Step 3 - GROUND THE GENERATOR
Ground the generator by tightening the grounding nut on the front control panel against a grounding wire (Fig.
3). 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 rod are not included in generator contents. Grounding codes can vary by location.
Contact a local electrician for area codes.
WARNING: Failure to properly ground the generator increases the chances of electric
shock.
SUBSEQUENT STARTING OF THE GENERATOR
USING THE GENERATOR
Before connecting electrical devices, allow the generator to run for a few minutes to stabilize the speed and voltage
output.
CAUTION: Become familiar with the markings on the panel before connecting electrical devices.
Connect electrical devices running on AC current according to their wattage requirements. The chart below shows
the rated and surge wattage of the generator.
The rated (running) wattage is the wattage the generator can produce on a continuous basis.
The surge wattage is the maximum amount of power the generator can produce for an extremely short period of
time (seconds). Many electrical devices such as refrigerators require short bursts of extra power in addition to the
rated wattage listed by the device to start their motors. The surge wattage ability of the generator covers this extra
power requirement.
Item Rated (Running) Wattage Surge Wattage
56180 1800 1500
The total running wattage requirement of the electrical devices connected to the generator should not exceed the
rated wattage of the generator itself. To calculate the total wattage requirement of the electrical devices you plan
to connect, find the rated (or running) wattage of each device. This number should be listed somewhere on the
device or in its instruction manual. If this wattage cannot be found, calculate it by multiplying the Voltage require-
ment by the Amperage drawn:
Watts = Volts x Amperes

Fig. 6 - Estimated wattage requirements of common electrical devices
If the electrical specifications are not available for your electronic devices, estimate the watts requirement of the
device by using the chart in Figure 6.
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 of the generator, DO NOT connect all
these devices. Select a combination of electrical devices, which have a total rated wattage lower than or equal to
the rated wattage of the generator.
CAUTION: The generator can run at its surge wattage capacity for only a short time. Connect electrical devices
requiring a rated (running) wattage equal to or less than the rated wattage of the generator. Never connect devices
requiring a rated wattage equal to the surge wattage of the generator. This can trip the circuit protectors (circuit
breakers).
Note: The above wattage figures are estimates. Check the wattage listed on the electrical device before consulting
this chart. Once the electrical devices have been chosen, connect them according to the following procedure:
1. Plug in each electrical device, making sure that the device is turned off.
2. Check power indicator light. The generator may be overloaded. If so, unplug the electronics, then restart the
generator before plugging the load back in. If the reset button does not reset, wait several minutes and try again. If
the power light still does not come on, call the customer service number for further instructions.
15
USING THE GENERATOR
CAUTION: Do not connect 50Hz loads to the generator.
SOME NOTES ABOUT POWER CORDS: Long or thin cords can drain the power provided to an electrical
device by the generator. When using such cords, allow for a slightly higher rated wattage requirement by the elec-
trical device. See Figure 7 for recommended cords based on the power requirement of the electrical device.

MAINTENANCE
HIGH ALTITUDE OPERATION ABOVE 2000 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 2000 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.
The kit should be installed by a qualified mechanic. Refer to the instructions included with your altitude kit for
more information about installation. You can order the kit at wenproducts.com by searching part 56180-HA27 for
2000 to 7000 feet above sea level.
CLEANING THE GENERATOR
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.
Always try to use the generator in a cool, dry place. If the generator becomes dirty, clean the exterior with a damp
cloth, a soft brush, a vacuum or pressurized air.
CHECKING THE OIL
Check the oil level of the generator according to the Recommended Maintenance Schedule in Fig. 9. The genera-
tor is equipped with an automatic shutoff to protect it from running on low oil. The generator should be checked
before each use for proper oil level. This is a critical step for proper engine starting. To check the oil level:

WARNING: To prevent serious injury from fire, follow the kit installation proce-
dures 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.
1. Make sure the generator is on a level surface.
2. Open access panel. Clean around oil fill. Remove dipstick and wipe the
dipstick with a clean rag. Insert the dipstick into the oil fill opening without
screwing in. Remove the dipstick to check the oil mark. Add oil if the oil
mark covers less than one half of the dipstick.
3. Slowly add more oil and repeat step 2 until the oil mark reaches to the
top of dipstick (Fig. 2). Do not over fill the crankcase.
4. Reinstall oil dipstick and access panel.
DRAINING THE CARBURETOR
The carburetor drain can be accessed from the backside of the genera-
tor between the air filter assembly and the engine (Fig. 9). After each use,
open up the carburetor drain with a screwdriver and drain out any gasoline
that has built up inside. Once the fuel has drained, close the drain back up
with the same screwdriver. It is best to do this after every use and required
before storing the generator for long periods of time.
NOTE: WE SUGGEST RUNNING YOUR GENERATOR AT LEAST ONCE A
MONTH IN ORDER TO MAXIMIZE THE LIFESPAN OF THE GENERATOR.

MAINTENANCE
CHANGING/ADDING OIL
Change the oil according to the Recommended Maintenance Schedule in Figure 9. Change the oil when the en-
gine is warm. This will allow for complete drainage. Change 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. The oil capacity of the generator engine is 13.5 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.
1. Place generator on elevated platform such as table or desk. Put a container next to it to hold the used oil. Turn
the vacuum relief valve to “OFF” position.
2. Unscrew the dipstick from the engine and set aside.
3. Tilt the generator so the used oil flows from the engine into the container. Tilt some more to ensure all oil is
out of the crankcase.
4. Fill the crankcase with fresh oil and reinstall the dipstick. Clean any oil spillage..
To rell the crankcase with oil, follow these steps:
1. Make sure the generator is on a level surface. Tilting the generator to assist in filling will cause oil to flow into
engine areas and will cause damage. Keep generator level!
2. Remove the dipstick from the engine.
3. Using a funnel or appropriate dispenser, add the correct amount of oil into the crankcase. The engine is
equipped with a low oil pressure sensor and will not start if the amount of oil is insufficient.
4. Reinstall dipstick.
NOTE: Never dispose of used motor oil in the trash or down a drain. Please call a local recycling center or auto
garage to arrange oil disposal.
AIR CLEANER MAINTENANCE
Routine maintenance of the air cleaner helps maintain proper airflow to the carburetor. Occasionally check that
the air cleaner is free of excessive dirt. Refer to Recommended Maintenance Schedule in Figure 8.
1. Unscrew the cover bolt (Fig. 10) and remove the air cleaner cover.
Remove the air cleaner element from the casing.
2. Check and clean the foam air cleaner element. Replace with a new
one if the element is damaged. Good elements can be washed in soapy
water, dried and reused. There is no need to add oil to the element.
Wipe off excessive oil from the air cleaner case. Small amount of oil in
the element is normal and necessary for the engine to work properly.
3. Reinstall the air cleaner element and cover.

DRAINING THE FUEL TANK
Clean fuel tank each year and before storing the generator for longer than one to two months. To drain the fuel
tank and carburetor:

SPARK PLUG MAINTENANCE
The spark plug is important for proper engine operation. A good spark plug should be intact, free of deposits,
and properly gapped. Refer to Recommended Maintenance Schedule in Figure 9. To inspect the spark plug:
1. Remove spark plug boot. Be careful not to tear insulation or wire.
2. Unscrew the spark plug from the engine using the spark plug wrench provided. 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 for cracks or excessive electrode wear. Replace as necessary.
4. Measure the plug gap with a wire gauge. The gap should be 0.7 to 0.8 mm (0.028-0.031 in).
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. Screw the spark plug back into the spark plug hole using the spark plug wrench. Do not over-tighten spark
plug. Recommended tightening of spark plug is ½ to ¾ of a turn after spark plug gasket contacts spark plug hole.
Reinstall the spark plug boot.
FUEL FILTER CUP CLEANING
The fuel filter cup is a small well underneath the fuel valve. It helps to trap dirt and water that may be in the fuel
tank before it can enter the engine. To clean the fuel filter cup:
1. Turn the fuel valve to the “OFF” position.
2. Unscrew the fuel filter cup from the fuel valve using a wrench. Turn the valve toward you and unscrew (Fig. 11).
3. Clean the cup of all sediments using a rag or brush.
4. Reinstall the fuel filter cup.
MAINTENANCE
Fig. 11
1. Remove the fuel cap; carefully turn the generator over to pour the
gasoline in the fuel tank to appropriate container.
2. Once fuel is drained, reinstall the fuel cap.
3. Turn on the engine and keep the engine running until it stops.
This burns out the fuel in the carburetor and fuel tank.
4. Store the emptied gasoline in a suitable place.
CAUTION: Do not store fuel for more than two months.

SPECIFICATIONS
STORAGE & TRANSPORT PROCEDURES
CAUTION: Never place any type of storage cover on the generator while it is still hot.
If the generator is being stored for short periods of time (30 to 60 days), add stabilized fuel to the fuel tank until
full. NOTE: Filling the tank reduces the amount of air in the tank and helps fight deterioration of fuel. Run the
engine for 2 – 3 minutes allowing stabilized fuel mixture to circulate through the carburetor. Never store with fuel
in the tank for more than two months. When storing the generator for extended periods of time:
• Drain the fuel tank (see “Draining the Fuel Tank” in the “Maintenance” section).
• Drain the carburetor (see “Draining the Carburetor” in the Maintenance section).
• Change oil.
• Do not obstruct any ventilation openings.
• Keep the generator in a cool dry area.
When transporting generator:
• Drain the fuel tank if possible (see “Draining the Fuel Tank” in the “Maintenance” section).
• Keep the generator upright. Never place the generator side down. Doing so will make it difficult to start.
