EQUIPMENT DESCRIPTION
This generator is an engine-driven, revolving field, alter-
nating current (AC) generator. It was designed to supply
electrical power for operating compatible electrical light-
ing, appliance, tool and motor loads. This manual
contains information for a generator that operates 120
volt, single phase, 60Hz devices that require up to 2000
watts (2.0 kW) of power that pull up to 15 amps at 120
volts.
CAUTION: Do not exceed the generators
wattage/amperage capacity. Add up the rated
watts of all devices you are connecting to
generator receptacles at one time. This total
should not be greater than 2000 watts for this
generator. In most cases rated watts of the
electrical device can be found on the device
nameplate. If the device nameplate gives
only volts and amps, multiply volts times
amps to obtain watts (volts x amps = watts).
The generators revolving field is driven at about 3600
rpm by a single-cylinder engine.
Every effort has been expended to make sure that the
information in this manual is both accurate and current.
However, Generac reserves the right to change, alter or
otherwise improve the product at any time without prior
notice.
DANGER: Do not tamper with engine gov-
erned speed. High operating speeds are
dangerous and increase risk of personal
injury or damage to equipment. The genera-
tor supplies correct rated frequency and
voltage only when running at proper gov-
erned speed. Incorrect frequency and/or
voltage can damage some connected electri-
cal loads. Operating at excessively low
speeds imposes a heavy load at such
reduced speeds, when adequate engine
power is not available, and may short engine
life.
SAFETY RULES
This generator set was designed and manufactured for
specific applications. Do not attempt to modify the unit
or use it for any application it was not designed for. If
you have any questions about your generators applica-
tion, ask your Dealer/Distributor or consult the factory.
The manufacturer could not possibly anticipate every cir-
cumstance that might involve a hazard. For that reason
warnings in the Manual and warnings on tags or decals
affixed to the unit are not all-inclusive. If you intend to
handle, operate or service the unit by a procedure or
method not specifically recommended by the manufac-
turer, first make sure that such a procedure or method
will not render this equipment unsafe or pose a threat to
you and others.
Read this manual carefully and become familiar with
your generator set. Know its applications, its limitations
and any hazards involved.
The generator produces a very powerful voltage that
can cause extremely dangerous electrical shock.
Avoid contact with bare wires, terminals, etc. Never
permit any unqualified person to operate or service
the generator.
Never handle any kind of electrical cord or device
while standing in water, while barefoot or while hands
or feet are wet. Dangerous electrical shock will result.
The National Electric Code requires the frame and
external electrically conductive parts of generator be
properly connected to an approved earth ground.
Local electrical codes may also require proper ground-
ing of the generator. Consult with a local electrician
for grounding requirements in your area.
Use a ground fault circuit interrupter in any damp or
highly conductive area (such as metal decking or
steel work).
Do not use any worn, bare, frayed or otherwise dam-
aged electrical cord sets with the generator. Using any
defective cord set may result in electrical shock or
damage to equipment and/or property.
Operate generator only on level surfaces and where
it will not be exposed to excessive moisture, dirt, dust
or corrosive vapors.
