Equipment Description
Readthis manualcarefully and becomefamiliar
...... with yourgenerator. Knowitsapplications, its
limitationsand anyhazardsinvolved.
Thegeneratoris an engine-driven, revolvingfield, alternating
current (AC)generator. It was designedto supply electrical
power for operatingcompatible electricallighting, appliances,
tools and motor loads.Thegenerator's revolving field is
driven at about3,600 rpm by a twin-cylinder engine.
This generator incorporates GFCI(Ground Fault Circuit
Interrupter) outlet protection and has its neutral bonded to
ground to comply to OSHAinspections on job sites. This
generatorwill not function when connectedto a 2 pole
transfer switch since the home or building main breakerbox
also has a neutral bonded to ground. When both the
generator andthe home or building breakerbox contains a
neutral bonded to ground, the generators GFCIwill open and
no outlets will function.
_i, WARNING Removingthe neutral bond could result in
'_l_lJ death, bodily injury and/or property damage.
