If you do not understand any portion of this manual, contact your

nearest GENERAC/GUARDIAN

®

Authorized Dealer for starting,

operating and servicing procedures.  
Throughout this publication, and on tags and decals affixed to the

generator, DANGER, WARNING, CAUTION and NOTE blocks are

used to alert you to special instruction about a particular operation

that may be hazardous if performed incorrectly or carelessly.

Observe them carefully. Their definitions are as follows:

After this heading, you can read instructions that, if
not strictly complied with, will result in personal injury
or property damage.

After this heading, you can read instructions that, if
not strictly complied with, may result in personal
injury or property damage.

After this heading, you can read instructions that, if
not strictly complied with, could result in damage to
equipment and/or property.

NOTE:

After this heading, you can read explanatory statements

that require special emphasis. These safety warnings cannot

eliminate the hazards that they indicate.  Common sense and

strict compliance with the special instructions while performing

the service are essential to preventing accidents.
Four commonly used safety symbols accompany the 

DANGER,

WARNING

and 

CAUTION

blocks. The type of information each

indicates follows:

This symbol points out important safety 

information that, if not followed, could endanger 
personal safety and/or property of you and others.

This symbol points out potential explosion hazard.

This symbol points out potential fire hazard.

This symbol points out potential electrical shock 
hazard.

The operator is responsible for proper and safe use of
the equipment. We strongly recommend that the
operator read this 

Owner’s Manual

and thoroughly

understand all instructions before using this
equipment. We also strongly recommend instructing
other users to properly start and operate the unit.  This
prepares them if they need to operate the equipment
in an emergency.

CAUTION!

Always disconnect spark plug wire and place the

wire where it cannot contact the spark plug to prevent accidental

starting when setting up, transporting, adjusting or making

repairs to your generator.
•  The generator produces dangerously high voltage that can

cause extremely hazardous 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 the generator be properly

connected to an approved earth ground. Local electrical codes

may also require proper grounding 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 worn, bare, frayed or otherwise damaged electrical

cord sets with the generator.

•  Operate generator only on level surfaces and where it will not

be exposed to excessive moisture, dirt, dust or corrosive

vapors.

•  Gasoline is highly 

FLAMMABLE

and its vapors are

EXPLOSIVE

. Do not permit 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.

•  Never add fuel while unit is running.
•  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 

FIRE

or an 

EXPLOSION.

•  Never store generator with fuel in tank where gasoline vapors

might reach an open flame, spark or pilot light (as on a

furnace, water heater or clothes dryer). 

FIRE

or

EXPLOSION

may result.

•  Generator exhaust gases contain 

DEADLY 

carbon monoxide

gas.This dangerous gas, if breathed in sufficient

concentrations, can cause unconsciousness or even death.

Operate this equipment only in the open air where adequate

ventilation is available.

•  Allow at least 2 feet of clearance on all sides of generator or

you could damage the unit. Never operate the unit inside any

room or enclosure where the free flow of cooling air into and

out of the unit might be obstructed. Review “Cold Weather

Operation” on page 12.

For the purpose of this warranty "consumer use" means personal residential household use by original purchaser. This does not apply to units
