ADDING / CHECKING ENGINE 

FLUIDS AND FUEL

BEFORE ADDING/CHECKING ENGINE 

FLUIDS AND FUEL, REVIEW SAFETY 

SECTION STARTING ON PAGE 5.

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:

•  Level of Engine oil

•  Level of gasoline in the fuel tank

•  Secured connection to an undamaged LPG tank
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 

muffler 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 fill 

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 fill plug/

dipstick.

The unit as shipped does not contain oil in the engine. You 

must add engine oil before starting the generator for the first 

time. 

NOTICE

The engine does not contain engine oil as shipped.

Attempting to start the engine can damage engine components. 

The owner of the generator is responsible to ensure the proper oil 

level is maintained during the operation of the generator. Failure to 

maintain the proper oil level can result in engine damage.

NOTICE

During the first five hours of operating the generator make sure to 

not exceed 50% of the rated running watts until the unit is broken 

in properly. Make sure to vary to load occasionally to allow stator 

windings to heat and cool. Adjusting the load will also help seat 

piston rings. Check oil more often during the first couple times of 

operating the generator. 

NOTICE

Weather will affect engine oil performance. Change the type of 

engine oil used based on weather conditions to suit the engine 

needs.

ADDING GASOLINE TO THE FUEL TANK 

BEFORE ADDING GAS TO THE TANK 

PLEASE REVIEW FUEL SAFETY SECTION 

ON PAGE 7

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 fill the 

fuel tank:

1.  Shut off the generator.
2.  Allow the generator to cool down so all surface areas of 

the muffler and engine are cool to the touch.

3.  Move the generator to a flat 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 overfill the tank. The gasoline level should NOT 

be higher than the filler neck.

7.  Install the fuel cap by rotating clockwise until you hear 

a click, indicating the cap is completely installed.

CAUTION

Avoid prolonged breathing of gasoline vapors.
