OPERATION
ADDING / CHECKING ENGINE
FLUIDS AND FUEL
Before adding/checking engine
fl uids and fuel, review Safety on
page 7.
DANGER
Filling the fuel tank with gasoline while
the generator is running can cause
gasoline to leak and come in contact
with hot surfaces that can ignite the
gasoline.
Before starting the generator, always check the level of:
Engine oil
Gasoline in the fuel tank
Once the generator is started and the engine gets
warm, it is not safe to add gasoline to the fuel tank or
engine oil to the engine while the engine is running or
the engine and muffl er are hot.

Checking and / or Adding Engine Oil

WARNING
Internal pressure can build in the
engine crankcase while the engine
is running. Removing the oil fi ll plug/
dipstick while the engine is hot can
cause extremely hot oil to spray out
of the crankcase and can severely
burn skin. Allow engine oil to cool for
several minutes before removing the oil
fi ll plug/dipstick.
The unit as shipped does not contain oil in the
engine. You must add engine oil before starting the
generator for the fi rst time. See Checking Engine Oil
on page 30 and Adding Engine Oil on page 31
for instructions on checking engine oil level and the
procedure for adding engine oil.

NOTICE
The generator does not contain engine oil as shipped.
Attempting to start the engine without adding
engine oil can permanently damage internal engine
components.

Adding Gasoline to the Fuel Tank

WARNING
Never refuel the generator while the
engine is running.
Always turn the engine off and allow
the generator to cool before refueling.
Required Gasoline – Only use gasoline that meets the
following requirements:
Unleaded gasoline only
Gasoline with maximum 10% ethanol added
Gasoline with an 87 octane rating or higher
Filling the Fuel Tank – Follow the steps below to fi ll the
fuel tank:
1. Shut off the generator.
2. Allow the generator to cool down so all surface
areas of the muffl er and engine are cool to the
touch.
3. Move the generator to a fl at surface.
4. Clean area around the fuel cap.
5. Remove the fuel cap by rotating counterclockwise.
6. Slowly add gasoline into the fuel tank. Be very
careful not to overfi ll the tank. The gasoline level
should NOT be higher than the bottom of the fi ller
neck (see Figure 20).
