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.

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 1-(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 / CHECK 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 15 fl. oz. (0.44 L).
• 30W Engine Oil
Temperatures above 40°F
• 10W-30 Engine Oil
Temperatures between 0°F - 40°F
• Synthetic 5W-30 Engine Oil
All temperature ranges
ENGINE OIL RECOMMENDATIONS
Select good quality detergent oil bearing the American Petroleum Institute (API) service classifications
SJ, SL, or SM (synthetic oils may be used). Select the SAE viscosity grade of oil that matches the
expected operating temperature.
CAUTION! Keep the generator level. Tilting the generator to
assist in filling will cause oil to flow into the wrong areas of the
engine and cause damage.
1. Open the oil access cover (Fig. 2 - 1), remove and wipe the oil
dipstick with a clean rag. Insert the dipstick into the oil fill opening
without screwing it in.
2. Remove the dipstick to check the oil mark on the dipstick (Fig.
3). Add oil if the oil mark covers less than one half of the dipstick.
3. Slowly add oil and repeat step 2 until the oil mark measures
between the upper limit mark and halfway mark of the dipstick. Do
not overfill the crankcase.
4. Wipe clean any oil leaks and firmly tighten the dipstick.
CAUTION! For subsequent operation, the oil
level should be checked before each use, or
after every 8 hours of operation. The gen-
erator is equipped with a low-oil sensor and
will not start without a sufficient amount of
oil. Follow the instructions on the next page
to check the oil level.

ECO-MODE SWITCH
This generator is equipped with an Eco-Mode Idle Control Switch (Fig. 12). Engaging the switch automatically ad-
justs the engine to match the 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.
Keep this switch engaged when the power load requirement is less than 1000W. Do not engage the Eco-Mode
Switch when the total load is more than 1000W. The generator engine must run at full speed to supply power for
anything over 1000W.
OIL LEVEL SHUTDOWN
The low oil indication light (yellow) will turn on to remind you that the engine oil level is low and need to be refilled.
The generator is equipped with a low oil pressure shutoff that will automatically stop the engine when the oil level is
too low to protect the unit from damage. The oil level of the engine should be checked before each start to ensure
that the engine crankcase contains sufficient lubricant.

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
1700W 2000W
What this means:
The generator can produce a maximum of
1700W 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 2000W 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 page19, 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 1700W.
It is recommended to maintain a load at or
below 1530W (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 2000W.
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).

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 (1700W) 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 (Fig. 14) 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-(800) 232-1195 M-F 8-5 CST.
NOTE: The NEMA 5-20 receptacles are capable of connecting devices up to 20A only when two generators are
parallel connected. When operating a single generator, do not exceed 14A (1700 running watts) on this receptacle.

trical devices connected and running.
2. Allow generator to run at no load for a few minutes to stabilize
internal temperatures.
3. Turn the engine switch to the FUEL OFF position (Fig. 15). This fea-
ture will burn off the remaining fuel in the carburetor, helping to com-
bat fuel degradation and prolong engine life. You may also choose to
shut off the engine quickly (e.g. for refueling, moving the generator,
etc.) by turning the engine switch to the OFF position (Fig. 16), but
this option will let fuel remain in the carburetor. Be sure to drain the
carburetor (see page 26) after use to prolong engine life.
4. Close the vacuum relief valve (Fig. 17) on the top of the fuel cap by
rotating it counterclockwise to the OFF position.
WARNING! Allow the generator to cool for several minutes
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 generator in the fu-
ture. Never store the generator for extended periods of time (over
2 months) with fuel in the fuel tank. Refer to “Storing the Genera-
tor” on page 28.

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 15 minutes every month to maximize its 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.
24
MAINTENANCE
WARNING! Make sure generator is shut off before performing any inspection or maintenance procedures.
CHECKING / ADDING OIL
Check the oil level of the generator according to the Recommended Main-
tenance Schedule in Table 4. The oil level should be checked before each
use or every 8 hours of operation. The oil capacity of the generator engine
is 15 fl. ounces. Add oil when the oil level is low.
For proper type and weight of oil refer to “Add / Check Oil” section on
page 12. The generator is equipped with an automatic shutoff to protect
it from running on low oil. To check the oil level:
1. Make sure the generator is on a level surface. Do not tilt the generator
to assist in filling, as oil will flow into engine areas and cause damage.
Keep generator level!
2. Open the oil access cover (Fig. 18 - 1). Remove the dipstick (Fig. 19)
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. 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
step 3 until the oil mark measures between the upper limit mark and half-
way mark of the dipstick. Do not over fill the crankcase.
5. Reinstall dipstick and wipe clean any spill oil with a rag.
DRAINING / CHANGING THE OIL
Change the oil according to the Recommended Maintenance Schedule in Table 4. Change the oil more often if oper-
ating 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 complete drainage.
Drain the oil from the generator according to the following steps.
1. Place generator on an elevated platform such as table or desk. Prepare a container underneath the oil fill to catch
the oil as it drains.
2. Open the oil access cover. Remove the dipstick and tilt the generator towards you to allow the oil to drain from
the engine completely.
3. Reinstall the oil dipstick and tighten it securely. Wipe clean any oil spillage and replace the oil access cover.
NOTE: Do not dispose of used motor oil in the trash or down a drain. Please call a local recycling center or auto
garage to arrange proper oil disposal.

instructions on maintaining. To inspect the spark plug:
1. Open the spark plug access cover (Fig. 20 - 1).
2. Pull up to remove the black plastic spark plug boot. Be careful
not to tear any insulation or wire.
3. Use a spark plug wrench to unscrew and remove the spark plug
from the engine.
4. Visually inspect the spark plug for cracks or excessive elec-
trode wear. If the electrodes are worn or burned, or porcelain is
cracked, replace with a NGK BPR5HS/Torch E5T spark plug (Part
No. 56202i-102), available 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 wire gauge (Fig. 21). The gap
should be 0.6 mm - 0.8 mm. Carefully adjust the gap if necessary.
7. 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.
NOTE: The spark plug torque is 15 ft. lb. The recommended tightening of spark plug is ½ to ¾ of a turn after spark
plug gasket contacts spark plug hole. Do not over-tighten the spark plug.
8. Reinstall the spark plug boot over the spark plug.
9. Reinstall the spark plug access cover.

cess oil in a clean absorbent cloth. A small amount of oil in the
element is normal and necessary for the engine to work properly.
If the element is damaged, replace it with a new one.
4. Reinstall the air filter element and close the air filter cover. Close
the the cover. Secure it with the screws. Reinstall the oil access
panel.
CAUTION! Running the engine with a dirty, damaged, or missing air filter element will result in possible
danger and cause the engine to wear out prematurely.
DRAINING THE CARBURETOR
Drain the carburetor after every use and before storing
the generator (refer to Table 4). Draining the
carburetor can help prevent build-up and blockages caused
by stagnant fuel inside of the carburetor.
1. Remove the oil access panel. Unscrew the four Phillips-head
screws and remove the side panel (Fig. 22 - 1).
2. Open up the carburetor drain screw (Fig. 24) with a Phillips
screwdriver and drain out any gasoline that has built up inside the
carburetor.
3. Once the fuel has drained, tighten the drain screw with the
screwdriver.
NOTE: Make sure to drain your carburetor before storing the gen-
erator for long periods of time.
4. Close the back cover and muffler cover, and secure them with

TRANSPORTATION & STORAGE
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.
WARNING! Store the generator upright in a cool and dry location, away from sources of heat, open flames,
sparks or pilot lights.
TRANSPORTING THE GENERATOR
To prevent fuel spillage when transporting, be sure to perform the following:
1. Tighten the fuel cap and turn the fuel valve to the OFF position.
2. Flip the engine switch to the OFF position.
3. Drain the fuel tank if possible. Refer to page 27, “Draining the Fuel Tank.”
4. Keep the generator upright. Never place the generator on its side or upside down - doing so could damage the
internal components of the generator and make it difficult to start.
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 26, “Draining the
Carburetor.”
• 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
