OPERATION
the generator off. Restart the unit and add loads back to
the generator one at a time being careful not to exceed the
generators wattage rating.
Lubricant:
The oil indicator will light and the engine will automatically
shut off whenever the lubricant level in the engine becomes
low. The engine may not be restarted until sufficient engine
lubricant has been added to the generator.
NOTE: It is normal for the indicator lights to illuminate and/
or blink each time the engine is started. Once the engine
warms up, the lights should default to the pattern above.
CHECKING/ADDING LUBRICANT
See Figures 3 - 4.
NOTICE:
Attempting to start the engine before it has been properly
filled with lubricant will result in equipment failure.
Engine lubricant has a major influence on engine perfor-
mance and service life. For general, all-temperature use,
SAE 10W-30 is recommended. Always use a 4-stroke motor
lubricant that meets or exceeds the requirements for API
service classification SJ.
NOTE: Non-detergent or 2-stroke engine lubricants will
damage the engine and should not be used.

Loosen the screw at the top of the engine maintenance
cover. Remove cover and set aside.
 Unscrew the oil cap/dipstick and remove.
 Wipe dipstick clean and re-seat in hole; do not re-thread.
 Remove dipstick again and check lubricant level.
Lubricant level should fall between the minimum and
maximum marks on the dipstick.
 If level is low, add engine lubricant until the fluid level
rises between the minimum and maximum marks on the
dipstick.
 Replace and secure the oil cap/dipstick.
 Replace the engine maintenance cover and reinstall the
screw to secure.
USING FUEL STABILIZER
Fuel gets old, oxidizes, and breaks down over time. Adding
a fuel stabilizer (not included) extends the usable life of fuel
and helps prevent deposits from forming that can clog the
fuel system. Follow fuel stabilizer manufacturer’s directions
for correct ratio of stabilizer to fuel.

Mix fuel stabilizer and gasoline prior to filling the tank
by using a gas can or other approved fuel container and
shaking gently to combine.
NOTE: To control the amount of fuel stabilizer being added
to the engine, always mix fuel stabilizer with gasoline
before fueling the tank rather than adding fuel stabilizer
directly into the generator’s fuel tank.
 Replace and secure the fuel tank cap.
 Start and run the engine for at least 5 minutes to allow
stabilizer to treat the entire fuel system.
OXYGENATED FUELS
NOTICE:
Do not use E15 or E85 fuel (or fuel containing greater
than 10% ethanol) in this product. It is a violation of
federal law and will damage the unit and void your
warranty.
Fuel system damage or performance problems resulting
from the use of an oxygenated fuel containing more than
the percentage of oxygenates stated below
are not covered
under warranty.
Ethanol. Gasoline containing up to 10% ethanol by volume
(commonly referred to as E10) is acceptable.
E15 and E85
are not.
CHECKING/ADDING FUEL
See Figures 5 and 8.
WARNING:
Gasoline and its vapors are highly flammable and
explosive. To prevent serious personal injury and property
damage, handle gasoline with care. Keep away from
ignition sources, handle outdoors only, do not smoke
while adding fuel, and wipe up spills immediately.
When adding gas to the generator, make sure the unit is
sitting on a flat, level surface. If the engine is hot, let the
generator cool for at least five minutes before adding gas.
ALWAYS fill the fuel tank outdoors with the machine turned
off.

Remove the fuel cap slowly.
 Put the on/off switch in the ON ( I ) position.
 Fill the fuel tank to 1 in. below the top of the fuel neck.
 Replace and secure the fuel cap.
NOTE: Always use unleaded gasoline with a pump octane
rating of 86 or higher. Never use old, stale, or contaminated
gasoline, and do not use an oil/gas mixture. Do not allow dirt
or water into the fuel tank.
Do not use E85 fuel.
OPENING AND CLOSING VENTED FUEL CAP
See Figures 6 - 7.
The generator has a fuel cap with a vent that can be opened
and closed.

To open the vent, rotate the fuel cap lever to the OPEN
(I) position. The vent should be open during operation.
 To close the vent, rotate the fuel cap lever to the CLOSED
(O) position. The vent should be closed when the
generator is not in use.
