• Do not handle any kind of electrical device while standing

in water, while barefoot, or while hands or feet are wet.
DANGEROUS ELECTRICAL SHOCK MAY RESULT.

• If personnel must stand on metal or concrete while install-

ing, operating, servicing, adjusting or repairing this equip-
ment, place insulative mats over a dry wooden platform.
Work on the equipment only while standing on such insula-
tive mats.

• The National Electrical Code (NEC), Article 250 requires

the frame and external electrically conductive parts of the
generator to be connected to an approved earth ground
and/or grounding rods. This grounding will help prevent
dangerous electrical shock that might be caused by a
ground fault condition in the generator set or by static elec-
tricity. Never disconnect the ground wire.

• Wire gauge sizes of electrical wiring, cables and cord sets

must be adequate to handle the maximum electrical current
(ampacity) to which they will be subjected.

• Before installing or servicing this (and related) equipment,

make sure that all power voltage supplies are positively
turned off at their source. Failure to do so will result in haz-
ardous and possibly fatal electrical shock.

• Connecting this unit to an electrical system normally sup-

plied by an electric utility shall be by means of a transfer
switch so as to isolate the generator electric system from
the electric utility distribution system when the genera-
tor is operating. Failure to isolate the two electric system
power sources from each other by such means will result
in damage to the generator and may also result in injury or
death to utility power workers due to backfeed of electrical
energy.

• Generators installed with an automatic transfer switch will

crank and start automatically when NORMAL (UTILITY)
source voltage is removed or is below an acceptable pre-
set level. To prevent such automatic start-up and possible
injury to personnel, disable the generator’s automatic start
circuit (battery cables, etc.) before working on or around
the unit. Then, place a “Do Not Operate” tag on the genera-
tor control panel and on the transfer switch.

• In case of accident caused by electric shock, immediately

shut down the source of electrical power. If this is not pos-
sible, attempt to free the victim from the live conductor.
AVOID DIRECT CONTACT WITH THE VICTIM. Use a
nonconducting implement, such as a dry rope or board,
to free the victim from the live conductor. If the victim is
unconscious, apply first aid and get immediate medical
help.

• Never wear jewelry when working on this equipment.

Jewelry can conduct electricity resulting in electric shock,
or may get caught in moving components causing injury.

FIRE HAZARDS

• Keep a fire extinguisher near the generator at all times.

Do NOT use any carbon tetra-chloride type extinguisher.
Its fumes are toxic, and the liquid can deteriorate wiring
insulation. Keep the extinguisher properly charged and be
familiar with its use. If there are any questions pertaining
to fire extinguishers, consult the local fire department.

EXPLOSION HAZARDS

• Do not smoke around the generator. Wipe up any fuel or

oil spills immediately. Ensure that no combustible materi-
als are left in the generator compartment, or on or near
the generator, as FIRE or EXPLOSION may result. Keep
the area surrounding the generator clean and free from
debris.

• These generator sets may operate using one of several types

of fuels. All fuel types are potentially FLAMMABLE and/or
EXPLOSIVE and should be handled with care. Comply with
all laws regulating the storage and handling of fuels. Inspect
the unit’s fuel system frequently and correct any leaks
immediately. Fuel supply lines must be properly installed,
purged and leak tested according to applicable fuel-gas
codes before placing this equipment into service.

• Gaseous fluids such as natural gas and liquid propane (LP)

gas are extremely EXPLOSIVE. Natural gas is lighter than
air, and LP gas is heavier than air; install leak detectors
accordingly.
