Safety Rules

GENERAL HAZARDS

• For safety reasons, the manufacturer recommends that the

installation, initial start-up and maintenance of this equipment

is carried out by a Dealer.

• The engine exhaust fumes contain carbon monoxide, which

can be DEADLY. This dangerous gas, if breathed in sufficient

concentrations, can cause unconsciousness or even death.

Do NOT alter or add to the exhaust system or do anything that

might render the system unsafe or in noncompliance with appli-

cable codes and standards.

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

and other moving or hot parts. Never remove any drive belt or

fan guard while the unit is operating.

• Adequate, unobstructed flow of cooling and ventilating air is

critical to correct generator operation. Do not alter the instal-

lation or permit even partial blockage of ventilation provisions,

as this can seriously affect safe operation of the generator. The

generator MUST be installed outdoors.

• When working on this equipment, remain alert at all times.

Never work on the equipment when physically or mentally

fatigued.

• Inspect the generator regularly, and contact the nearest Dealer

for parts needing repair or replacement.

• Before performing any maintenance on the generator, discon-

nect its battery cables to prevent accidental start up. Disconnect

the cable from the battery post indicated by a NEGATIVE, NEG

or (–) first, then remove the POSITIVE, POS or (+) cable. When

reconnecting the cables, connect the POSITIVE cable first, the

NEGATIVE cable last.

• 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 dan-

gerous operating conditions from leaking exhaust gases, fuel

leakage, oil leakage, etc.

ELECTRICAL HAZARDS

• All generators covered by this manual produce dangerous

electrical voltages and can cause fatal electrical shock. Utility

power delivers extremely high and dangerous voltages to the

transfer switch as does the standby generator when it is in

operation. Avoid contact with bare wires, terminals, connec-

tions, etc., while the unit is running. Ensure all appropriate

covers, guards and barriers are in place, secured and/or locked

before operating the generator. If work must be done around

an operating unit, stand on an insulated, dry surface to reduce

shock hazard.

• Do not handle any kind of electrical device while stand-

ing in water, while barefoot, or while hands or feet are wet.

DANGEROUS ELECTRICAL SHOCK MAY RESULT.

• The National Electrical Code (NEC) requires the frame and external

electrically conductive parts of the generator to be connected to

an approved earth ground. Local electrical codes also may require

proper grounding of the generator electrical system.

• After installing this home standby electrical system, the genera-

tor may crank and start at any time without warning. When this

occurs, load circuits are transferred to the STANDBY (genera-

tor) power source. To prevent possible injury if such a start and

transfer occur, always set the generator's AUTO/OFF/MANUAL

switch to its OFF position before working on equipment and

remove the fuse from the generator control panel.

• 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 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

• For fire safety, the generator must be installed and maintained

properly. Installation must always comply with applicable

codes, standards, laws and regulations. Adhere strictly

to local, state and national electrical and building codes.

Comply with regulations the Occupational Safety and Health

Administration (OSHA) has established. Also, ensure that the

generator is installed in accordance with the manufacturer's

instructions and recommendations. Following proper installa-

tion, do nothing that might alter a safe installation and render

the unit in noncompliance with the aforementioned codes,

standards, laws and regulations.

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

Extinguishers rated "ABC" by the National Fire Protection

Association are appropriate for use on the standby electric

system. Keep the extinguisher properly charged and be familiar

with its use. Consult the local fire department with any ques-

tions pertaining to fire extinguishers.

EXPLOSION HAZARDS

• 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.

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

gas are extremely EXPLOSIVE. Install the fuel supply system

according to applicable fuel-gas codes. Before placing the

home standby electric system into service, fuel system lines

must be properly purged and leak tested according to applica-

ble code. After installation, inspect the fuel system periodically

for leaks. No leakage is permitted.
