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, appliances, tools and motor loads. This manual
contains information for a generator that operates 120
and/or 240 Volt, single phase, 60 Hz devices that require up
to 3,500 watts (3.5 kW) of power that pull up to
29.2 Amps at 120 Volts or 14.6 Amps at 240 Volts.

CAUTION!

Do Not exceed the generator’s

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 3,500 watts. 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 3,500 watt generator has the following features:

• 120/240 Volt, 20 Amp locking type receptacle and a

120 Volt, 30 Amp locking type receptacle.

• 120 Volt, 15 Amp receptacles.

• Low Oil Shutdown: Automatically shuts down the engine

if oil drops below safe operation level.

• Four gallon overhead fuel tank with fuel gauge.

• The generator’s revolving field is driven at about

3,600 rpm by a Generac Power Systems 6.5 h.p. engine.

WARNING!

Do Not tamper with engine

governed speed. High operating speeds are
dangerous and increase risk of personal injury or
damage to equipment. The generator supplies
correct 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. When adequate
engine power is not available engine life may be
shortened.

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/distributor 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.

DANGER!

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 electric 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 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.

The engine exhaust from this product contains

chemicals known to the State of California to

cause cancer, birth defects, or other

reproductive harm.
