OPERATION
CHECKING/ADDING LUBRICANT
See Figure 9.
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 performance
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.
This engine comes with a feature that will shut off the engine
when a specific oil level is not maintained. The engine will
not restart until an appropriate oil level is reached.
NOTE:
Non-detergent or 2-stroke engine lubricants will
damage the engine and should not be used.

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 hatched areas on
the dipstick.

If level is low, add engine lubricant until the fluid level rises
to the upper portion of the dipstick.

Replace and secure the oil cap/dipstick.
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 add-
ed 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 Figure 10.
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 5 minutes before adding gas. ALWAYS fill
the fuel tank outdoors with the machine turned off.

Remove the fuel cap slowly.

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.
GenSmart
™
MONITORING SYSTEM
See Figure 11.
The GenSmart
™
monitoring system displays wattage, volt-
age, hertz, and hours. To cycle through each display, press
and release the select/reset button.
Load Indicator
Measures the wattage output of the 2 x 120 Volt duplex GFCI
and 240 Volt, 30 Amp outlets located on the control panel.
Hour Meter
The digital hour meter operates whenever the engine is run-
ning and keeps track of how many hours the unit has been
used. Use this meter along with the accompanying engine
manual to determine when and what type of service on the
unit is needed. To display, press and release the select/reset
button to cycle through the displays until HRS appears.
