generator is installed, operated and serviced in  
accordance with the manufacturer’s instructions  
and recommendations. Following installation, do  
nothing that might render the unit unsafe or in  
noncompliance with the aforementioned codes,  
standards, laws and regulations.  
• The engine exhaust fumes contain carbon mon-  
oxide gas, which can be DEADLY. This dangerous  
gas, if breathed in sufficient concentrations, can  
cause unconsciousness or even death. For that  
reason, adequate ventilation must be provided.  
This should be considered prior to installing the  
generator. The unit should be positioned to direct  
exhaust gasses safely away from any building  
where people, animals, etc., will not be harmed.  
Any exhaust stacks that ship loose with the unit  
must be installed properly per the manufacturer's  
instruction, and in strict compliance with appli-  
cable codes and standards.  
WARNING:  
This product contains or emits chemicals  
known to the state of California to cause  
cancer, birth defects or other reproductive harm.  
Study these SAFETY RULES carefully before install-  
ing, operating or servicing this equipment. Become  
familiar with this Owner’s Manual and with the unit.  
The generator can operate safely, efficiently and reli-  
ably only if it is properly installed, operated and  
maintained. Many accidents are caused by failing to  
follow simple and fundamental rules or precautions.  
The manufacturer cannot anticipate every possible  
circumstance that might involve a hazard. The warn-  
ings in this manual, and on tags and decals affixed  
to the unit are, therefore, not all inclusive. If a pro-  
cedure, work method or operating technique is used  
that the manufacturer does not specifically recom-  
mend, ensure that it is safe for others. Also make  
sure the procedure, work method or operating tech-  
nique utilized does not render the generator unsafe.  
DANGER  
Despite the safe design of this generator,  
operating this equipment imprudently, neglect-  
ing its maintenance or being careless can cause  
possible injury or death. Permit only responsible  
and capable persons to install, operate or main-  
tain this equipment.  
• 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 venti-  
lating air is critical in any room or building hous-  
ing the generator to prevent buildup of explosive  
gases and to ensure 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.  
• Keep the area around the generator clean and  
uncluttered. Remove any materials that could  
become hazardous.  
Potentially lethal voltages are generated by  
these machines. Ensure all steps are taken to  
render the machine safe before attempting to  
work on the generator.  
Parts of the generator are rotating and/or hot  
during operation. Exercise care near running  
generators.  
• When working on this equipment, remain alert  
at all times. Never work on the equipment when  
physically or mentally fatigued.

Important Safety Instructions  
• Before performing any maintenance on the gen-  
• 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.  
erator, disconnect its battery cables to prevent  
accidental start-up. Disconnect the cable from the  
battery post indicated by a NEGATIVE, NEG or (–)  
first. Reconnect that 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 dangerous operating con-  
ditions from leaking exhaust gases, fuel leakage,  
oil leakage, etc.  
• In case of accident caused by electric shock, imme-  
diately 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 imple-  
ment, such as a dry 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.  
• Never wear jewelry when working on this equip-  
ment. Jewelry can conduct electricity resulting in  
electric shock, or may get caught in moving com-  
ponents causing injury.  
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 well as the standby generator. Avoid contact  
with bare wires, terminals, connections, etc., on  
the generator as well as the transfer switch, if  
applicable. Ensure all appropriate covers, guards  
and barriers are in place before operating the gen-  
erator. 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  
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  
installing, operating, servicing, adjusting or repair-  
ing this equipment, place insulative mats over a  
dry wooden platform. Work on the equipment only  
while standing on such insulative mats.  
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 extin-  
guisher properly charged and be familiar with its  
use. If there are any questions pertaining to fire  
extinguishers, consult the local fire department.  
• The National Electrical Code (NEC) requires the  
frame and external electrically conductive parts  
of the generator to be connected to an approved  
earth ground. This grounding will help prevent  
dangerous electrical shock that might be caused  
by a ground fault condition in the generator set or  
by static electricity. Never disconnect the ground  
wire.  
• Wire gauge sizes of electrical wiring, cables and  
cord sets must be adequate to handle the maxi-  
mum 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 hazardous and pos-  
sibly fatal electrical shock.  
• Connecting this unit to an electrical system nor-  
mally 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 operat-  
ing. 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.  
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 com-  
bustible materials are left in the generator com-  
partment, or on or near the generator, as FIRE or  
EXPLOSION may result. Keep the area surround-  
ing 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 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 prop-  
erly installed, purged and leak tested according to  
applicable fuel-gas codes before placing this equip-  
ment into service.  
• Diesel fuels are highly FLAMMABLE. 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.
