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, single phase, 60 Hz

devices that require up to 9,000 watts (9.0kW) of

power that pull up to 75 Amps at 120 Volts or

37.5 Amps at 240 Volts.

ACAUTION] 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 9,000 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 generator's revolving field is driven at about

3600 rpm by a twin-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.

ADANGER] Do not tamper with engine

governed speed. High operating speeds are

dangerous and increase the risk of personal

injuryor damage to equipment. The generator

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

aheavy load and, when adequate engine

power is not available, may shorten engine

life

are EXPLOSIVE. Never allow smoking, open

flames, sparks or heat in the vicinity while

handling gasoline. Avoid spilling gasoline on a hot

engine. Comply with all laws regulating storage and

handling of gasoline.

• Do not overfill the fuel tank. Always allow room for

fuel expansion. If tank is overfilled, fuel can

overflow onto a hot engine and cause a FIRE or

an EXPLOSION.

•Never store a generator with fuel in the tank where

gasoline vapors might reach an open flame, spark

engine. You could damage the unit or injure yourself.

•Never operate the generator:

in rain; in any enclosed compartment; if connected

electrical devices overheat; if electrical output is

lost; if engine or generator sparks; if flame or smoke

is observed while unit is running; if unit vibrates

excessively,

GROUNDING THE

GENERATOR

The National Electric Code requires the frame and

external electrically conductive parts of the generator

be properly connected to approved earth ground.

Local electrical codes may also require proper

grounding of the unit. A grounding wing nut (Figure 1)

is provided for this purpose.

Grounding

Wing Nut

Generally, connecting a No. 12 AWG (American Wire

Gauge) stranded copper wire to the grounding wing

nut and to an earth-driven copper or brass grounding

rod (electrode) provides adequate protection against

electrical shock. However, local codes may vary

widely. Consult with a local electrician for grounding

requirements in your area. Be sure to keep the ground

wire attached while you connect the electrode.

Properly grounding the generator helps prevent

electrical shock if ground fault conditions exists in the

generator or in connected electrical devices. Proper

grounding also helps dissipate static electricity, which

often builds up in ungrounded devices.

future, use only high quality detergent oil rated with

API service classification SE or higher. Use no special

additives. Select the oil's viscosity grade according to

instructionsgiven in the engine owner's manual.

=_m i=lllF4111F&'_II

To add oil to the generator:

•Make sure unit is on a level surface.

• Clean around oil fill cap and remove it

•Remove oil dipstick, wipe clean and fully reinsert in

engine block.

•Slowly fill engine with oil until it reaches the full

mark on the dipstick Stop occasionally to check oil

level Do not overfill.

•Install oil dipstick.

•Install oilfill cap. Hand tighten securely.

,_. CAUTION! Any attempt to crank or start the

engine before it has been properly serviced

with the recommended oil results in an engine

failure.

NOTE: The generator's revolving field rides on a

pre-iubricated and sealed bali bearing that requires

no additional lubrication for the life of the bearing.

Add Gasoline

ADANGER! NEVER fill fuel tank indoors.

NEVER fill fuel tank when engine is running or

hot. DO NOT light a cigarette or smoke when

filling the fuel tank.

,_ DANGER! Do not overfill the fuel tank.

Always leave room for expansion.

• Use regular UNLEADED gasoline in the generator.

DO NOT use premium gasoline. DO NOT mix oil

with gasoline. DO NOT overfill the gas tank.

• Clean area around fuel fill cap; remove cap.

• Fill fuel tank with clean, fresh, unleaded gasoline.

Be careful not to overfill Allow 1/2" of tank space for

fuel expansion (Figure 4).

1_" AirSpace _nk

• Install fuel cap and wipe up any spilled gasoline

IMPORTANT: It is important to prevent gum deposits

from forming in essential fuel system parts such as

the carburetor, fuel filter, fuel hose or tank during

storage. Also, experience indicates that

alcohol-blended fuels (called gasohol, ethanol or

methanol) can attract moisture, which leads to

separation and formation of acids during storage.

Acidic gas can damage the fuel system of an engine

while in storage. To avoid engine problems, the fuel

system should be emptied before storage of 30 days

or longer. See "Storage" on page 13. Never use

engine or carburetor cleaner products in the fuel tank

or permanent damage may occur.
