To ensure that the generator runs smoothly use only FRESH, UNLEADED GAS WITH AN OCTANE
RATING OF 87 OR HIGHER.
Add Gasoline
2.
a. Make sure the generator is on a level surface.
b. Unscrew gas cap and set aside (NOTE: the gas cap
may be tight and hard to unscrew).
c. Slowly add unleaded gasoline to the fuel tank. Be
careful not to overll. Please refer to the chart below
to nd the gas capacity of your generator model. The
fuel gauge on the top of the gas tank indicates how
much gasoline is in the generator gas tank.

GENERATOR SETUP (CONTINUED)
Step 5 - Grounding the Generator
Attach grounding wire
1.
a. Ground the generator by tightening the grounding
nut against a grounding wire.
b. Connect the other end to a copper or brass
grounding rod that’s driven into the earth.
A generally acceptable grounding wire is a No. 12 AWG
(American Wire Gauge) stranded copper wire.
Grounding codes can vary by location. Please contact a local
electrician to check the grounding regulations for your area.
WARNING: Failure to properly ground the generator can result in electrocution.
High Altitude Operation
At high altitude, the standard carburetor air/fuel mixture will be too rich. Performance will decrease, and
fuel consumption will increase. A very rich mixture will also foul the spark plug and cause hard starting.
Operation at an altitude that diers from that at which this engine was certied, for extended periods of
time, may increase emissions. High altitude performance can be improved by specic modications to the
carburetor. If you always operate your generator at altitudes above 5,000 feet (1,500 meters), have a dealer
perform this carburetor modication. This engine, when operated at high altitude with the carburetor
modications for high altitude use, will meet each emission standard throughout its useful life. Even with
carburetor modication, engine horsepower will decrease about 3.5% for each 1,000-foot (300-meter)
increase in altitude. The eect of altitude on horsepower will be greater than this if no carburetor
modication is made.
When the carburetor has been modied for high altitude operation, the air/fuel mixture will be too lean
for low altitude use. Operation at altitudes below 5,000 feet (1,500 meters) with a modied carburetor may
cause the engine to overheat and result in serious engine damage.

Step 1 - Check the oil
Check the oil
1.
The generator is equipped with an automatic shuto to
protect it from damage due to low oil. Nonetheless, you
should check the oil level of the engine before each use to
ensure that the engine crankcase has a sucient amount.
To check the oil level:
a. Make sure the generator is on a level surface.
b. Remove dipstick.
c. With a dry cloth, wipe the oil o of the stick.
d. Insert the dipstick completely back into its hole in
the engine case. the pull it out again. There should
now be oil on the stick. If there is no oil on the stick,
or oil only at the very end of the stick, you should
add oil until the engine crankcase is lled (see
“Adding Oil” portion of the “Maintenance” section).
e. Be sure to replace the dipstick when nished
checking oil.
NOTE: The oil capacity for your generator can be found in
the “Specications” section of this manual.

USING THE GENERATOR
AC Usage
● You may connect electrical devices running on AC current according to their wattage
requirements.
● The chart below shows the rated and surge wattage of your generator according to its model
number.
● The rated wattage corresponds to the maximum wattage the generator can output on a
continuous basis.
● The surge wattage corresponds to the maximum amount of power the generator can output for
a short period of time. Many electrical devices such as refrigerators require short bursts of extra
power, in addition the rated wattage listed by the device, to stop and start their motors. The
surge wattage ability of the generator covers this extra power requirement.
Fuel Source Rated (Running Wattage) Surge (Peak) Wattage
Gasoline 12500 15000
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 wish to connect, nd the rated (or running) wattage of each device. This
number should be listed somewhere on the device or in its instruction manual.
If you cannot nd this wattage, you may calculate it by multiplying the Voltage requirement by the
Amperage drawn: Watts = Volts x Amps. If these specications are not available you may estimate
the Watts required by your device by using the chart on the next page.
Once you have found the rated wattage requirement of each electrical device, add these numbers
to nd the total rated wattage you wish to draw from the generator. If this number exceeds
the rated wattage of the generator, DO NOT connect all these devices. Select a combination of
electrical devices, which has a total rated wattage lower than or equal to the rated wattage of the
generator.

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. The V-Twin engine in this generator has two spark plugs,
one on each side. Both plugs are located just underneath the OHV covers.
Improper maintenance may cause reduced fuel economy, misres, trouble starting, or damage
to the spark plug threads.
