OPERATION

FUEL SELECTOR SWITCH 

Position the fuel selector switch on the front control panel 

to the desired fuel choice. 

Push the fuel selector switch fully upward for gasoline 

operation.
Push the fuel selector switch fully downward for propane 

operation. 

BREAK-IN PERIOD

For  proper  break-in,  do  not  exceed  50%  of  the  rated 

running  watts  (6000  watts)  during  the  first  five  hours  of 

operation.
Vary the load occasionally to allow stator windings to heat 

and cool and help seat the piston rings. 

LOW IDLE

NOTICE

Always start the generator with Low Idle OFF. Allow the 

engine speed to stabilize before switching Low Idle ON.

NOTICE

Frequency output of the generator is dependent on 

engine speed. DO NOT use Low Idle when powering 

sensitive electronics or large surge loads, such as an 

air conditioner, electric pump, refrigerator, or when 

connected to a home transfer switch.

Low Idle minimizes fuel consumption, noise, and engine 

wear by lowering the engine RPM to idle (2400 RPM) when 

electrical loads have been turned off and automatically 

returns to rated speed when loads are turned back on.  
Turn Low Idle ON when powering intermittent, non-

electronic loads, such as power tools at a construction site. 

BEFORE STARTING THE GENERATOR

Verify that:

•  The generator is placed in an safe, appropriate location. 
• 

The generator is on a dry, flat, and level surface.

• 

The engine is filled with oil.

•  All loads are disconnected.

Fire and explosion hazard. DO NOT move or tip the 

generator during operation.

STARTING THE ENGINE: GASOLINE

During Push-Button or Remote Start the engine will 

automatically set the choke and begin the start sequence. 

If the engine fails to start, the generator will attempt to 

start the engine two more times. The battery switch can be 

turned off at any time during the automatic start sequence 

to abort the engine start attempt.
If the cranking speed drops after each unsuccessful 

attempt, then the battery may not be adequately charged. 

See BATTERY MAINTENANCE section
