INTRODUCTION
Thank you for purchasing this model of the Stationary
Emergency Generator set product line.
Every effort was expended to make sure that the
information and instructions in this manual were
both accurate and current at the time the manual was
written. However, the manufacturer reserves the right
to change, alter or otherwise improve this product(s)
at any time without prior notice.
READ THIS MANUAL THOROUGHLY
If any portion of this manual is not understood, con-
tact the nearest Authorized Service Dealer for start-
ing, operating and servicing procedures.
Throughout this publication, and on tags and decals
affixed to the generator, DANGER, WARNING,
CAUTION and NOTE blocks are used to alert person-
nel to special instructions about a particular service
or operation that may be hazardous if performed
incorrectly or carelessly. Observe them carefully.
Their definitions are as follows:
DANGER
After this heading, read instructions that, if not
strictly complied with, will result in serious person-
al injury, including death, or property damage.
After this heading, read instructions that, if not
strictly complied with, may result in personal
injury or property damage.
After this heading, read instructions that, if not
strictly complied with, could result in damage to
equipment and/or property.
NOTE:
After this heading, read explanatory statements
that require special emphasis.
These safety warnings cannot eliminate the hazards
that they indicate. Common sense and strict compli-
ance with the special instructions while performing
the service are essential to preventing accidents.
Four commonly used safety symbols accompany the
DANGER, WARNING and CAUTION blocks. The type
of information each indicates is as follows:
This symbol points out important safety infor-
mation that, if not followed, could endanger
personal safety and/or property of others.
This symbol points out potential explosion
hazard.
This symbol points out potential fire hazard.
This symbol points out potential electrical shock
hazard.
The operator is responsible for proper and safe use
of the equipment. The manufacturer strongly recom-
mends that the operator read this Owner's Manual
and thoroughly understand all instructions before
using this equipment. The manufacturer also strong-
ly recommends instructing other users to properly
start and operate the unit. This prepares them if they
need to operate the equipment in an emergency.
OPERATION AND MAINTENANCE
It is the operator's responsibility to perform all safety
checks, to make sure that all maintenance for safe
operation is performed promptly, and to have the
equipment checked periodically by an Authorized
Service Dealer. Normal maintenance service and
replacement of parts are the responsibility of the
owner/operator and, as such, are not considered
defects in materials or workmanship within the terms
of the warranty. Individual operating habits and usage
contribute to the need for maintenance service.
Proper maintenance and care of the generator ensure
a minimum number of problems and keep operating
expenses at a minimum. See an Authorized Service
Dealer for service aids and accessories.
Operating instructions presented in this manual
assume that the generator electric system has been
installed by an Authorized Service Dealer or other
competent, qualified contractor. Installation of this
equipment is not a “do-it-yourself” project.
HOW TO OBTAIN SERVICE
When the generator requires servicing or repairs,
simply contact an Authorized Service Dealer for
assistance. Service technicians are factory-trained
and are capable of handling all service needs.
When contacting an Authorized Service Dealer or the
factory about parts and service, always supply the
complete model number of the unit as given on the
front cover of this manual or on the DATA LABEL
affixed to the unit.

Stationary Emergency Generator
Important Safety Instructions
Safety 001 Rev. B 10/08
• Before performing any maintenance on the gen-
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.
ELECTRICAL HAZARDS
• All Stationary Emergency 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 generator.
Avoid contact with bare wires, terminals, connec-
tions, etc., on the generator as well as the transfer
switch, if applicable. Ensure all appropriate cov-
ers, guards and barriers are in place before operat-
ing 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
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.
• 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 danger-
ous electrical shock that might be caused by a
ground fault condition in the generator 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.
• Stationary Emergency Generators installed with
an automatic transfer switch will crank and start
automatically when normal (utility) source volt-
age is removed or is below an acceptable preset
level. To prevent such automatic start-up and pos-
sible 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 generator control panel
and on the transfer switch.
• 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.
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.
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 generators may operate using one of sev-
eral 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.
