1In the Interest of Safety

This manual outlines the construction,

function and servicing procedures of

the Briggs & Stratton Power Products®

“Hand-Held” generator series. It is

structured for use by trained

technicians that are working in a

properly equipped shop. Familiarity

with the proper method of using tools,

measuring equipment and workshop

procedures are essential to performing

successful maintenance and repair on

this equipment.

Ensure that all specified tools and/or

equipment are available before

attempting to service this equipment.

For a detailed discussion of the

fundamental principles involved with

the physics of electrical power

generation, refer to the "Familiarization

and Troubleshooting Guide

(Publication #86262 Revision 3 or

later)". This manual is available

through your Briggs & Stratton Central

Distributor.

Safety Alert Symbols

NOTE: This notation is used to

inform you of a method, reference

or procedure that could assist with

specific operations or decisions.

HAZARD SYMBOLS AND MEANINGS

Toxic Fumes Electrocution

Hot Surface Chemical Burns

Explosive Pressure

Kick Back Entanglement

Disconnect

Spark Plug

Fire

Read Goggles

Explosion

• Operate generator ONLY outdoors.

• Keep at least 2 feet of clearance on all

sides of generator for adequate

ventilation.

• Do not operate generator inside any

building or enclosure, including the

generator compartment of a

recreational vehicle (RV).

Running generator gives off

carbon monoxide, an

odorless, colorless, poison

gas.

Breathing carbon monoxide

will cause nausea, fainting or

death.

The safety alert symbol ( ) is used

to identify safety information about

hazards that can result in personal

injury. A signal word (DANGER,

WARNING, CAUTION) is used

with the alert symbol to indicate the

potential severity of injury. In addition,

a hazard symbol may be used to

represent the type of hazard.

DANGER: Indicates a hazard

which, if not avoided will result

in death or serious injury.

WARNING: Indicates a hazard

which, if not avoided could

result in death or serious

injury.

CAUTION: Indicates a hazard

which, if not avoided might

result in death or serious

injury.

CAUTION: When used without the

alert symbol, indicates a situation that

could result in damage to equipment.

DANGER

• When using generator for backup

power, notify utility company. Use

approved transfer equipment to isolate

generator from electric utility.

• Use a ground circuit fault 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 use generator 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 hands or feet are

wet.

• Do not allow unqualified persons or

children to operate or service

generator.

Generator produces

powerful voltage.

Failure to isolate generator

from power utility can result

in death or injury to electric

utility workers due to

backfeed of electrical energy.

DANGER

• National electric code requires

generator to be properly grounded to

an approved earth ground. Call an

electrician for local grounding

requirements.

Failure to properly ground

generator can result in

electrocution, especially if the

generator is equipped with a

wheel kit.

DANGER

Introduction • Section 1

Hand-Held Series Generators • Familiarization & Troubleshooting Guide

Safety Practices

• Generator exhaust gases contain

DEADLY carbon monoxide gas.

This dangerous gas, if breathed

in sufficient concentrations, can

cause unconsciousness or even

death. Operate and service this

equipment only in the open air

where adequate ventilation is

available.

• These generators were designed

and manufactured for

recreational 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 manuals and warnings on tags

or decals affixed to the units are

not all-inclusive. If you intend to

handle, operate or service a unit

with a procedure or method not

specifically recommended by the

manufacturer, make sure that

such a procedure or method will

not render the equipment unsafe

or pose a threat to you and

others.

• Read these procedures carefully

and become familiar with your

generator set. Know its

applications, its limitations and

any hazards involved.

• Do not allow any open flame, spark,

heat, or lit cigarette around battery

during, and for several minutes after

charging.

• Wear protective goggles, rubber

apron, and rubber gloves.

Storage batteries give off

explosive hydrogen gas

during recharging.

Hydrogen gas stays around

battery for a long time after

battery has been charged.

Slightest spark will ignite

hydrogen and cause

explosion.

You can be blinded or

severely injured.

Battery electrolyte fluid

contains acid and is

extremely caustic.

Contact with battery fluid

will cause severe chemical

burns.

DANGER

• Do not touch hot surfaces.

• Allow equipment to cool before

touching.

Running engines produce

heat. Temperature of muffler

and nearby areas can reach

or exceed 150°F (65°C).

Severe burns can occur on

contact.

DANGER

• This generator does not meet U.S.

Coast Guard Regulation 33CFR-183 and

should not be used on marine

applications.

• Failure to use the appropriate U.S.

Coast Guard approved generator could

result in bodily injury and/or property

damage.

WARNING

WHEN ADDING FUEL

• Turn generator OFF and let it cool at

least 2 minutes before removing gas

cap. Loosen cap slowly to relieve

pressure in tank.

• Fill fuel tank outdoors.

• Do not overfill tank. Allow space for

fuel expansion.

• Keep all fuel away from sparks, open

flames, pilot lights, heat, and other

ignition sources.

• Do not light a cigarette or smoke.

WHEN OPERATING EQUIPMENT

• Do not tip engine or equipment at

angle which causes fuel to spill.

WHEN TRANSPORTING OR

REPAIRING EQUIPMENT

• Transport/repair with fuel tank EMPTY

or with fuel shutoff valve OFF.

• Disconnect spark plug wire.

• Do Not operate generator in a moving

vehicle or watercraft, because motion

can cause fuel to spill.

WHEN STORING FUEL OR

EQUIPMENT WITH FUEL IN

TANK

• Store away from furnaces, stoves,

water heaters, clothes dryer or other

appliances that have pilot light or other

ignition source because they can ignite

fuel vapors.

Fuel and its vapors are

extremely flammable and

explosive.

Fire or explosion can cause

severe burns or death.

WARNING

The engine exhaust from this product

contains chemicals known to the State of

California to cause cancer, birth defects,

or other reproductive harm.

WARNING

• Hand-held generators produce a very powerful

voltage that can cause an extremely dangerous

electrical shock. Avoid contact with bare wires,

terminals, etc. Never permit an untrained person to

service or assist with the procedures discussed in this

guide.

• Never handle any kind of electrical cord or device

while standing in water, while barefoot, or while

hands or feet are wet.

• Do not use worn, bare, frayed or otherwise damaged

electrical cord sets with any generator set. Using a

defective cord may result in an electrical shock or

damage to the test equipment and/or the unit.

• 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.

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

expansion. If the tanks are over-filled, fuel can overflow on

`to a hot engine and cause FIRE or EXPLOSION.

• These units require an adequate flow of cooling air for their

continued proper operation. Never operate or service any

unit while inside any enclosure where the free flow of

cooling air into and out of the unit might be obstructed.

Without sufficient cooling airflow, the units quickly

overheat, damaging the generator and/or nearby property.

• Never start or stop a unit with electrical loads connected

to receptacles and with the connected loads turned ON.

Start the engine and let it stabilize before connecting any

electrical loads. Turn OFF and disconnect all electrical

loads before shutting down any generator.

• This entire book is filled with important safety information

- please read it carefully.
