BATTERY
RECEPTACLE CIRCUIT
BREAKER
The circuit breakers protect the receptacles
and alternator. Overloading generator will
trip circuit breaker. A short circuit in item
being powered will also trip breaker. If this
occurs, unplug electrical load from recep-
tacle. Let circuit breaker cool down. Push
circuit breaker button to reset.
Electric motors need higher starting current.
They require up to three-times their rated
wattage to start. The starting current needed
may be too high. This can cause nuisance
circuit breaker tripping. To help prevent
this, start electric motors first. Connect ad-
ditional items to generator after starting
motors. If this continues to happen, reduce
the total generator load.
Note:
High ambient temperature will cause
nuisance tripping.

ENGINE OIL
We ship the generator without oil in the
engine crankcase. You must add oil before
starting engine. See engine owner’s manual
for specific oil type.
CHECKING OIL LEVEL AND
ADDING OIL
Follow steps below to check oil level. Make
sure engine is level and stopped.
1. Remove dipstick (see Figure 6). Wipe
dipstick clean.
2. Insert dipstick into oil filler neck. Oil
level should be at top of filler neck the
upper limit mark on dipstick.
3. If level is low, fill to top of oil filler neck
(see Figure 6). Only use oil recom-
mended in engine owner’s manual.
Note:
If oil level is too low, oil alert system
will shutdown engine and prevent engine
from restarting.

FUEL
WARNING: Gasoline presents
a hazard of fire or explosion.
Gasoline is flammable. Its vapor
is explosive.
Keep fuel out of children’s
reach.
Refuel generator in a well-
vented area. Do not fill fuel tank
in the dark. Do not refuel while
engine is running. Unhook all
electrical loads and shut off
engine before refueling.
Do not overfill fuel tank. Al-
ways allow room for fuel to
expand. If you overfill tank, fuel
can overflow onto hot engine.
This can cause fire or explo-
sion. After refueling, tightly
close fuel tank cap.
Do not spill fuel. Fuel or fuel
vapor may ignite. If fuel spills,
make sure area is dry before
starting engine.
Never smoke in refueling area.
Never allow open flames or
sparks in area.
•Store fuel in approved con-
tainer. Store fuel in a well-
vented area free of open flames
or sparks.

FEATURES
Continued
Use clean, fresh, unleaded gasoline. Use
gasoline with octane rating of 86 or higher.
Service station gasoline pumps should dis-
play the octane rating. Using gasoline with
lower octane level could damage engine.
Avoid getting dirt, dust, or water in fuel
tank. Do not mix oil with gasoline.
See engine owner’s manual for more
information.
ENGINE CIRCUIT BREAKER
This circuit breaker, or fuse, protects the
battery charging circuit. A short circuit will
trip the circuit breaker. The circuit breaker
will also trip if you install the battery wrong.
Push circuit breaker button to reset. The
fuse is located inside of the Keyswitch box.
