• 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 hazardous and pos-

sibly fatal electrical shock.

• Connecting this unit to an electrical system normally supplied

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 generator 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 preset level. To

prevent such automatic start-up and possible injury to person-

nel, 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 generator 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

• Properly ventilate any room or building housing the generator to

prevent build-up of explosive gas.

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

spills immediately. Ensure that no combustible materials 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.

• All fuel types are potentially FLAMMABLE and/or EXPLOSIVE

and should be handled with care. Comply with all laws regulat-

ing 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.

• Diesel fuels are highly FLAMMABLE.
