USING THE GENERATOR
If this is not your first time using the generator there are still steps you should take to prepare it for
operation each time you use it.
IMPORTANT: At this point you should be familiar with the procedures described in the first
portion of this section entitled “GENERATOR SETUP” If you have not yet read this section, go
back and read it now.
USING THE GENERATOR
AC Usage
●● You may connect electrical devices running on AC current according to their wattage
requirements.
●● The chart below shows the rated and surge wattage of your generator according to its model
number.
●● The rated wattage corresponds to the maximum wattage the generator can output on a
continuous basis.
●● The surge wattage corresponds to the maximum amount of power the generator can output for
a short period of time. Many electrical devices such as refrigerators require short bursts of extra
power, in addition the rated wattage listed by the device, to stop and start their motors. The
surge wattage ability of the generator covers this extra power requirement.
The total running wattage requirement of the electrical devices connected to the generator should
not exceed the rated wattage of the generator itself. To calculate the total wattage requirement of
the electrical devices you wish to connect, find the rated (or running) wattage of each device. This
number should be listed somewhere on the device or in its instruction manual.
If you cannot find this wattage, you may calculate it by multiplying the Voltage requirement by the
Amperage drawn: Watts = Volts x Amps. If these specifications are not available you may estimate
the Watts required by your device by using the chart on the next page.
Once you have found the rated wattage requirement of each electrical device, add these numbers
to find the total rated wattage you wish to draw from the generator. If this number exceeds
the rated wattage of the generator, DO NOT connect all these devices. Select a combination of
electrical devices, which has a total rated wattage lower than or equal to the rated wattage of the
generator.

CAUTION - The generator can only run at its surge wattage capacity for a very short time.
Connect only electrical devices requiring a rated (running) wattage equal to or less than
the rated wattage of the generator. Never connect devices requiring a rated wattage
equal to the surge wattage of the generator.
33
USING THE GENERATOR (CONTINUED)
1. Plug in devices
Plug in devices to the appropriate receptacle. When using
the generator in 120/240v mode, balance the load as closely
as possible. Placing more load on one side of the circuit will
reduce the breaker trip period.
2. Turn breaker on
Flip the circuit breaker up to the on position to allow power to
the receptacles.
34
Voltage Selector Switch
This generator features Power Boost Technology, which gives the user POWER BOOST
the ability to double the power in the generator for more heavy duty
applications.
The voltage selector switches the dual 120v AC windings of the generator
to produce “120V ONLY” or “120/240V”. If a 240V appliance is connected TECHNOLOGY
to the 4-prong receptacle, the switch must be in the “120/240V” position.
If only 120V appliances are being connected to the generator select the
“120V ONLY” position to double the 120v amperage and automatically balance the load.
WARNING - Only change the Voltage Selector Switch with the main AC Circuit Breaker
OFF. The generator can be seriously damaged if the Voltage Selector Switch is changed
with the breaker ON.
