EQUIPMENT
DESCRIPTION

This generator is an engine-driven, revolving field,
alternating current (AC) generator. It was designed to
supply electrical power for operating compatible electrical
lighting, appliance, tool and motor loads.

This manual contains information for a generator that
operates 120 and/or 240 Volt AC, single phase, 60Hz
devices that require up to 5,000 watts (5.0 kW) of power
that pull up to 41.7 Amps at 120 Volts or 20.8 Amps at
240 Volts.

CAUTION!

Do Not exceed the generator’s

wattage/amperage capacity. Add up the rated watts of all
devices you will connect to generator receptacles at one
time. This total should not be greater than 5,000 watts for
this generator. Review “Don’t Overload the Generator” on
page 10.

The generator’s revolving field is driven at about 3600 rpm
by a single-cylinder engine.

Every effort has been made to ensure that information in
this manual is accurate and current. However, Generac
reserves the right to change, alter or otherwise improve
the product and this document at any time without prior
notice.

CAUTION!

Do Not tamper with engine

governed speed. High operating speeds are
dangerous and increase the risk of personal injury
or damage to equipment. The unit supplies correctly
rated frequency and voltage only when running at
proper governed speed. Incorrect frequency and/or
voltage can damage some connected electrical loads.
Operating at excessively low speeds imposes a
heavy load on the engine, and may shorten engine
life.

The Emission Control System for this generator is
warranted for standards set by the Environmental
Protection Agency. For warranty information refer to the
engine owner’s manual.

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 generator’s application, ask
your dealer or consult the factory.

The manufacturer could not possibly anticipate every
circumstance 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 manufacturer,
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.

WARNING!

You must isolate the generator

from the electric utility by opening the electrical
system’s main circuit breaker or main switch if this
unit is used for backup power. Failure to isolate
the generator from the power utility may
result in injury or death to electric utility
workers and damage to the generator 
due to a
backfeed of electrical energy. Whenever unit is
providing backup power, the electrical utility must be
notified.

DANGER

! Generator exhaust gases contain

DEADLY carbon monoxide gas. Carbon
monoxide, if breathed in sufficient
concentrations, can cause unconsciousness or
death. 
Operate this equipment outdoors where
adequate ventilation is available.

The engine exhaust from this product

contains chemicals known to the State

of California to cause cancer, birth

defects, or other reproductive harm.
