Voltmaster Engine-Driven Generators 23
Operation: Operating the generator
Plugs and connected equipment
Use only 3-prong grounded plugs, 3-wire extension cords, and
3-wire or double-insulated power tools with the generator.
Full-power switch
Some models are equipped with a switch that allows selection of
120-volt power only or both 120- and 240-volt power.
■
When using the generator to power only 120-volt equipment, put
the full-power switch in the 120V position. In this position:
❑
The generator windings are connected in parallel
❑
The output of the generator is 120 volts
❑
The 240-volt receptacles are not functional
❑
The voltmeter indicates 120V
■
When using the generator to power 240-volt equipment, put the
power switch in the 120/240V position. In this position:
❑
Each 120-volt receptacle has half the power output of the
generator
❑
The 240-volt receptacles are functional
❑
The voltmeter indicates 240V
■
Before changing the switch position, remove all electrical loads
from the generator.
Idler
Some models are equipped with an idler switch. When the idler is
on, the engine will slow down when there is no electrical load on
the generator, improving fuel usage and generator life.
The generator should be started with the idler turned off. After the
engine has warmed up for 2 to 3 minutes, turn the idler on. If there
is no load on the generator, the engine speed will decrease. On
some models there will be a delay of 10 to 12 seconds before the
engine slows down.
With the idler turned on, when an electrical load is applied, the
engine speed will automatically return to normal and produce the
generator’s rated voltage.
For the idler to function, a battery must be connected to the engine.
