maintenance of this equipment be performed by an

Authorized Dealer. Inspect the generator regularly,

and contact the nearest Authorized Dealer forparts

needing repair or replacement.

•Operate generator only on level surfaces and

where it will not be exposed to excessive moisture,

dirt, dust or corrosive vapors.

•Keep hands, feet, clothing, etc., away from drive

belts, fans, and other moving parts. Never remove

any fan guard or shield while the unit is operating.

•Do NOT operate generator in the rain.

•Do not alter the construction of the generator or

change controls which might create an unsafe

operating condition.

•Never start or stop the unit with electrical loads

connected to receptacles AND with connected

devices turned ON. Start the engine and let it stabi-

lize before connecting electrical loads. Disconnect

all electrical loads before shutting down the gener-

ator.

•Do not insert objects through unit’s cooling slots.

•When working on this equipment, remainalert at all

times.

•Never work on the equipment when physically or

mentally fatigued.

•Never use the generator or any of its parts as a

step. Stepping on the unit can stress and break

parts, and may result in dangerous operating con-

ditions from leaking exhaust gases, fuel leakage,

oil leakage, etc.

1.5 — Exhaust and Location Hazards

•Adequate, unobstructed flow of cooling and venti-

lating air is critical to correct generator operation.

Do not alter the installation or permit even partial

blockage of ventilation provisions, as this can seri-

ously affect safe operation of the generator. The

generator MUST be operated outdoors.

•This exhaust system must be properly maintained.

Do nothing that might render the exhaust system

unsafe or in noncompliance with any local codes

and/or standards.

•Always use a battery operated carbon monoxide

alarm indoors, installed according to the manufac-

turers instructions.

•If you start to feel sick, dizzy, or weak after the gen-

erator has been running, move to fresh air IMME-

DIATELY. See a doctor, as you could have carbon

monoxide poisoning.

Figure 1-2. Hearing Hazard

(000103)

DANGER

Owner’s Manual for Portable Generator 3

1.6 — Electrical Hazards

•The generator produces dangerously high voltage

when in operation. Avoid contact with bare wires,

terminals, connections, etc., while the unit is run-

ning, even on equipment connected to the genera-

tor. Ensure all appropriate covers, guards and

barriers are in place before operating the genera-

tor.

•The National Electric Code (NEC) 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 the 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 dam-

aged electrical cord sets with the generator.

•Before performing any maintenance on the genera-

tor, disconnect the engine starting battery (if

equipped) to prevent accidental start up. Discon-

nect the cable from the battery post indicated by a

NEGATIVE, NEG or (–) first. Reconnect that cable

last.

•In case of accident caused by electric shock,

immediately shut down the source of electrical

power. If this is not possible, attempt to free the vic-

tim from the live conductor. AVOID DIRECT CON-

TACT WITH THE VICTIM. Use a non-conducting

implement, such as a rope or board, to free the vic-

tim from the live conductor. If the victim is uncon-

scious, apply first aid and get immediate medical

help.

1.7 — Fire Hazards

•Gasoline is highly FLAMMABLE and its vapors are

EXPLOSIVE. Do not permit smoking, open flames,

sparks or heat in the vicinity while handling gaso-

line.

•Never fill fuel tank indoors. 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 over-filled, fuel can over-

flow 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. Allow unit to cool entirely before storage.

•Wipe up any fuel or oil spills immediately. Ensure

that no combustible materials are left on or near

the generator. Keep the area surrounding the gen-

erator clean and free from debris and keep a clear-

ance of five (5) feet on all sides to allow for proper

ventilation of the generator.

•Do not insert objects through unit’s cooling slots.

•Do not operate the generator if connected electri-

cal devices overheat, if electrical output is lost, if

engine or generator sparks or if flames or smoke

are observed while unit is running.

•Keep a fire extinguisher near the generator at all

times.

1.8 — Unit Identification Label

See Figure 1-3. Information from the Unit Identification

Label is required when requesting information or ordering

service parts. For quick and easy reference, record the

Serial and Model numbers printed on the label in the

space provided on the front cover.
