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 single-cylinderengine.
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_J death, bodily injury and/or property damage.

Capacity
You must make sureyour generator cansupply enough
rated (running) and surge (starting) watts for the items you
will power at the same time. Follow these simple steps:
1. Selectthe itemsyou will power at the same time.
2. Total the rated(running) watts of these items. This is
the amount of power your generator must produce to
keepyour items running. Seethe table on the right.
3. Estimatehow many surge (starting) watts you will need.
Surge wattageis the short burst of power neededto
start electric motor-driven tools or appliancessuch asa
