EQUIPMENT

DESCRIPTION

Read this manual carefully and become familiar

with your generator. Know its applications, its
limitations and any hazards involved.

Thisgenerator is an engine-driven, revolving field, alternating

current (AC) generator.It was designed to supply electrical
power for operating compatible electrical lighting,appliances,
tools andmotor loads.Thegenerator's revolvingfield is

driven at about 3,600 rpm by a single-cylinderengine.

WARNING

The engine exhaust from this product contains I
chemicals known to the State of California to cause

cancer, b rth defects, or other reproduct ve harm.

DANGER

CAUTION! Do Not exceed the generator's
wattage/amperage capacity.See"Don't Overload the

Generator" on page I I.

Everyeffort hasbeenmade to ensurethat information inthis

manualisaccurateand current However,Generac reserves
the right to change,alter or otherwise improvethe product

and this document at anytime without prior notice.
The EmissionControl Systemfor this generator iswarranted

for standardsset by the Environmental Protection Agency.For
warranty informationrefer to the engineowner's manual.

SAFETY RULES

The safety alert symbol (_k) isusedwith a signalword
(DANGER, CAUTION,WARNING), a pictorial and/or a
safety messageto alert you to hazards.DANGER indicates

a hazardwhich, ifnot avoided,will result in death or serious
injury. WARNING indicatesa hazard which, if not avoided,

couldresult in death or serious injury.CAUTION
indicatesa hazardwhich, ifnot avoided,might result in

minor or moderate injury.CAUTION, when used
without the alert symbol, indicates a situation that could

Operate generator ONLY outdoors.
Keep at least 2 feet of clearance on all sidesof generator for

adequateventilation.
Do not operate generator insideany building or enclosure,

includingthe generator compartment of a recreational vehicle
(RV).

DANGER

National ElectricCode requires generator to be properly
grounded to an approved earth ground. Call an electrician for
local grounding requirements.

DANGER

When usinggenerator for backup power, notify utility
company.Use approved transfer equipment to isolate
generator from electric utility.

Use aground fault circuit interrupter (GFCI) in any damp or
highly conductive area,such as metal decking or steel work.

Do not touch bare wires or receptacles.
Do not usegenerator with electrical cords which are worn,

frayed,bare or otherwise damaged.
Do not operate generator in the rain.
Do not handle generator or electrical cords while standing in

water, while barefoot, or while handsor feet are wet.
Do not allow unqualified persons or children to operate or

service generator.

, WARNING

, WARNING

WHEN ADDING FUEL

Turn generator OFF and let it cool at least2 minutes before

removing gascap.Loosen cap slowly to relievepressure in tank_
Fill fuel tank outdoors.

Do not overfill tank.Allow spacefor fuel expansion.
Keepgasoline away from sparks,open flames, pilot lights, heat,

and other ignition sources.

Do not light a cigarette or smoke.

NHEN OPERATING EQUIPMENT

Do not tip engine or equipment at anglewhich causes

gasoline to spill.

tHEN TRANSPORTING OR REPAIRING EQUIPMENT

Transport/repair with fuel tank EMPTY or with fuel shutoff
valve OFE

Disconnect spark plug wire.

NHEN STORING GASOLINE OR EQUIPMENT WITH

FUEL IN TANK

Store awayfrom furnaces,stoves,water heaters, clothes
dryers or other appliancesthat have pilot light or other

ignition source becausethey can ignite gasoline vapors.

Do not touch hot surfaces.
Allow equipment to cool before touching.

CAUTION

Do not tamper with governed speed.Generator supplies
correct rated frequency and voltage when running at governed
speed.

Do not modify generator in any way.

CAUTION

See"Don't Overload Your Generator" on page I h
Start generator and let engine stabilize before connecting

electrical loads.
Connect electrical loads in OFF position, then turn ON for

operation.
Turn electrical loads OFF and disconnect from generator

before stopping generator.

DANGER

Do not allow any openflame, spark, heat, or lit cigarette

during andfor several minutes after charging a battery.
Wear protective goggles,rubber apron, and rubber gloves.

CAUTION

Use generator only for intended uses.
tf you have questions about intended use,askdealer or

contact Generac.
Operate generator only on level surfaces.

Do not expose generator to excessive moisture, dust, dirt, or
corrosive vapors.

Do not insert any objects through cooling slots.
tf connected devices overheat, turn them off and disconnect

them from generaton
Shut off generator if.'

-electrical output is lost;

-equipment sparks,smokes,or emits flames;

-unit vibrates excessively.

Your generator requires some assemblyand is ready for
use after it has been properly serviced with the

recommended oil and fuel.

If you have any problems with the assembly of your

generator, please call the generator helpline at

1-800-270-1408.

IMPORTANT: Any attempt to run the unit before it has

been serviced with the recommended oil wilt result in an
engine failure.

REMOVE G EN ERATOR

FROM CARTON

• Set the carton on a rigid flat surface with "This SideUp"
arrows pointing upward.

• Carefully open the top flaps of the shipping carton.

Review"Cold Weather Operation" on page9.

• Cut down corners at one end of carton from top to
bottom and laythat side of carton down flat.

• Remove all packing material, carton fillers, etc.

• Remove the generator from the shipping carton.

INSTALL WHEEL KIT

To installthe wheel kit, the following tool is required:

• Socket wrench with I/2" or 13mmsockets.

• Needle-nose pliers.
Install Wheel Kit as follows: (SeeFigure I)

• Placethe bottom of the generator cradle on a flat, even
surface.Temporarily place unit on blocks to ease
assembly.

• Slide axle through both axle mounting brackets on cradle
frame, as shown.

• Slide a wheel over the axle.

NOTE: Besure to installboth wheels with the air
pressure valve on the outboard side.

• Retain wheel on axle with the e-ring usinga needle-nose
pliers.You may add the fiat washer if desired.

• Repeat step 3 and 4 to secure second wheel.

• Remove the existing hardware from the vibration
mounts with 13mmwrench. Use the same hardware to

attach the mounting leg.

• Removethe temporary blocks.

• Center the handle bracket on generator frame at control
panel end of cradle.

• Attach handle bracket with two capscrews and two hex
nuts. Use two 13mm wrenches to tighten hardware.

• Check that all fasteners are tight andthe tires are
inflated between 15-40 PSI.

BEFORE STARTING THE

ENGINE

Add Oil

CAUTION! Any attempt to crank or start the engine

before it has been properly filled with the recommended
oil may result in an engine failure.

To fill your engine with oil:

• Place generator on a level surface.

• Follow the oil grade recommendations and oil fill
instructions given inthe engine owner's manual.

NOTE: The generator's revolving field rides on a
prelubricated and sealed ball bearing that requires no
additional lubrication for the life of the bearing.

Add Gasoline

_ ARNING! Never fill fuel tank indoors. Never

fill fuel tank when engine is running or hot.Allow

unit to cool for two minutes before refueling. Do
Not light a cigarette or smoke when filling the fuel

tank.

• Use regular UNLEADED gasolinewith the generator
engine.Do Not use premium gasoline. Do Not mix oil

with gasoline.

• Clean areaaround fuel fill cap,remove cap.

• Slowly add unleaded regular gasoline to fuel tank. Be
careful not to overfill.Allow about I/2" of tank spacefor
fuel expansion (Figure 2).

112" Air

Install fuel capand wipe up any spilled gasoline.

IMPORTANT: It is importantto prevent gum deposits
from forming in essentialfuel system parts,such asthe

carburetor,fuel filter,fuel hose or tank during storage.Also,
experience indicatesthat alcohol-blended fuels (called

gasohol,ethanol or methanol) canattract moisture, which
leadsto separation and formation of acids during storage.

Acidic fuel can damagethe fuel system of an enginewhile
in storage.

To avoid engine problems, the fuel system should be
emptied before storage of 30 daysor longer.See"Storage"
on page 12.Never useengine or carburetor cleaner
products in the fuel tank or permanent damagemay occur.

,_ WARNING! Do Not overfill the fuel tank.

Always allow room for fuel expansion.

KNOWYOUR GENERATOR

Read this owner's manual and safety rules before operating your generator.
