I CAUTION

The generator is an engine-driven, revolving field,
alternating current (AC) generator. It was designed to
supply electrical power for operating compatible electrical
lighting, appliances, tools and motor loads. The generator's
revolving field is driven at about 3,600 rpm by a singlecylinder engine. The generator is operated on liquefied
propane (LP) gas. It can operate on natural gas (NG) fuel
only after conversion by a licensed professional gaseous
fuel technician.
This generator incorporates GFCI (Ground Fault Circuit
Interrupter)
outlet protection and has its neutral bonded
to grounding fastener to comply to OSHA inspections on
job sites.

DANGER

This product is intended for residential use as an allweather temporary source of electric power. It is capable
of supplying power to loads such as heating, refrigeration
systems, and communication
systems. This product does
not qualify for emergency standby as defined by NFPA 70
(NEC). DO NOT use this generator for anything other
than it's intended purpose.
Every effort has been made to ensure that the information
in this manual is both accurate and current. However, the
manufacturer reserves the right to change, alter or
otherwise improve the generator and this documentation
at any time without prior notice.

Ground

Fault

Protection

WARNING

The generator's receptacles are equipped with Ground
Fault Circuit Interrupter
(GFCI) protection. This GFC[
device meets applicable federal, state and local codes.
The GFCI protects against electrical shock that may be
caused if your body becomes a path in which electricity
travels to reach the ground. This could happen if you
touch a "Live" appliance or wire, or are touching plumbing
or other materials that connect to the ground.
When protected by a GFC[ device, one may still feel a
shock, but the GFC[ should cut current off quickly enough
so that a person in normal health should not suffer any
serious electrical injury.

Only qualified
electricians
and gaseous
fuel
technicians
should attempt
fuel conversion
or
