3 Operating the Machine
3.1 Application
Generator
application
This machine is a heavy-duty, compact, sound-attenuated generator designed to
provide single and three-phase power for construction, commercial, and industrial
applications where reliable power is needed.
.
Safety notices Do not exceed the power output of the generator. Damage to tools or generator
will occur. Refer to Technical Data.
When using the generator as a standby or substitute power supply, make sure
the voltage and phase rotation of the line connections match those of the mains
lines. Failure to match phase rotation and voltage may cause equipment con-
nected to the generator to operate incorrectly! This could create unsafe operat-
ing conditions.
Do not exceed the rated current limit of any receptacle.
