OPERATION 

1

USING EFFICIENCY MODE

The inverter is equipped with an efficiency mode switch 

to minimize fuel consumption. In efficiency mode, the 

inverter will sense the load and adjust the engine RPM 

to the current load requirements. Efficiency mode 

should be used only after the inverter has been warmed 

up to operating temperature.
1. 

To turn on the efficiency mode, press the switch to 

the 

ON

 position).

2. 

If no load is present, the inverter RPM will drop 

down to an idle speed.

3. 

As a load is applied, the inverter will sense the load 

and engine RPM will increase according to the load 

applied.

4. 

To run the inverter at maximum power and RPM, 

press the efficiency mode switch to the 

OFF

 

position.

OVERLOAD RESET

An electrical overload or short circuit will trip the 

overload protection system by disconnecting the 

generator’s AC output even though the engine is still 

running. If this occurs, the overload alarm light will be 

illuminated red and the output indicator light will be off. 

The AC output can be restored as follows:

1. 

Turn off and unplug any electrical devices or 

cords from the 120-Volt AC 

receptacle on the 

control panel.

2.  Press the generator reset button on the control 

panel until the overload alarm light goes off and the 

output indicator light is illuminated green.

3. 

Check that the intended electrical running and 

starting loads do not exceed the generator’s 

capacity or have a licensed electrician rectify any 

fault causing a short circuit in the load.

4. 

Reconnect any electrical devices or cords to the 

receptacles on the control panel and then turn on 

the electrical loads as required.

SWITCHING FUEL SOURCES 

PLEASE REVIEW FUEL SAFETY 

SECTION ON PAGE 

The below assumes that the propane fuel line is already 

attached to the generator securely and safely.

While the unit is running simply turn the 

FUEL 

SELECTOR

 knob to the desired fuel source. If you 

want to switch from gasoline to propane make sure the 

propane tank valve is open before you switch. When 

you move from propane to gasoline shut the propane 

valve after you have switched to gas. 

NOTICE

If you do not plan on operating the unit on propane do not leave 

the propane tank valve open.

When starting on propane the engine may run rough for a few 

seconds while it purges gasoline in the carburetor. 

If the engine fails when switching fuel sources simply restart the 

unit on the fuel source that you switched to. 

STOPPING THE INVERTER

Normal Operation

During normal operation, use the following steps to 

stop your inverter:

1. 

Remove any connected loads from the control 

panel receptacles.

2. 

Allow the inverter to run at “no load” to reduce and 

stabilize engine and alternator temperatures.

3. 

Press and hold the Push Start/
