equipment.
SAFETY RULES
Study these SAFETY RULES carefully before installing, operating
or servicing this equipment. Become familiar with this Owner’s
Manual and with the unit. The generator can operate safely, effi-
ciently and reliably 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 warnings in this manual, and on
tags and decals affixed to the unit are, therefore, not all inclusive.
If a procedure, work method or operating technique is used that
the manufacturer does not specifically recommend, ensure that it
is safe for others. Also make sure the procedure, work method or
operating technique utilized does not render the generator unsafe.
n 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 respon-
sible and capable persons to install, operate or
maintain this equipment.
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.
n Parts of the generator are rotating and/or hot
during operation. Exercise care near running
generators.
GENERAL HAZARDS
For safety reasons, the manufacturer recommends that this •
equipment be installed, serviced and repaired by a Service
Dealer or other competent, qualified electrician or installation
technician who is familiar with applicable codes, standards
and regulations. The operator also must comply with all such
codes, standards and regulations.
Installation, operation, servicing and repair of this (and related) •
equipment must always comply with applicable codes, stan-
dards, 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, operat-
ed and serviced in accordance with the manufacturer’s instruc-
tions 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 monoxide 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 compli-
ance with applicable 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 in any room or building housing 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 seriously affect
safe operation of the generator.
Keep the area around the generator clean and uncluttered. •
Remove any materials that could become hazardous.
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 promptly repair or replace •
all worn, damaged or defective parts using only factory-
approved parts.
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. 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 dan-
gerous operating conditions 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 dan-
gerous voltages to the transfer switch as well as the 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 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.

Safety004 Rev. F 05/10
Safety Instructions
If personnel must stand on metal or concrete while installing, •
operating, servicing, adjusting or repairing 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 con-
nected 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 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 maximum electrical current (ampac-
ity) 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 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.
Stationary emergency 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 personnel, disable the generator’s automatic start cir-
cuit (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.
These generators 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.
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.

General Information
Data Label
This equipment is a revolving field, alternating current Stationary
Emergency Generator set. It is powered by a gaseous fueled
engine operating at 1800 rpm for 4-pole direct drive units, 3600
rpm for 2-pole direct drive units and 2300 - 3000 rpm for quiet
drive gear units. See the Specifications section for exact numbers.
The unit comes complete with a sound attenuated enclosure, inter-
nally mounted muffler, control console, mainline circuit breaker,
battery charger, and protective alarms as explained in the following
paragraph.
All AC connections, including the power leads from the alterna-
tor, 120 volt battery charger input and control connections to the
transfer switch are available in the main connection box.
The Stationary Emergency Generator incorporates the following
generator features:
• Rotor and Stator insulation is Class H rated as defined by NEMA
MG1-32.6, MG1-1.66. The generator is self ventilated and drip-
proof constructed.
• The voltage waveform deviation, total harmonic content of the
AC waveform and telephone influence factor have been evalu-
ated and are acceptable according to NEMA MG1-32.
The unit has been filled with 5W-20 engine oil at the factory. Use
a high-quality detergent oil classified “For Service SJ or SH.”
Detergent oils keep the engine cleaner and reduce carbon deposits.
When changing the engine oil, be sure to use 5W-30 engine oil
(synthetic oil is recommended).
Any attempt to crank or start the engine before
it has been properly serviced with the recom-
mended oil may result in an engine failure.
Use a mixture of half low silicate ethylene glycol base anti-freeze
and deionized water. Cooling system capacity is listed in the
specifications. Use only deionized water and only low silicate
anti-freeze. If desired, add a high quality rust inhibitor to the rec-
ommended coolant mixture. When adding coolant, always add the
recommended 50-50 mixture.
Do not use any chromate base rust inhibitor
with ethylene glycol base anti-freeze or chro-
mium hydroxide (“green slime”) forms and will
cause overheating. Engines that have been
operated with a chromate base rust inhibitor
must be chemically cleaned before adding eth-
ylene glycol base anti-freeze. Using any high
silicate anti-freeze boosters or additives will
also cause overheating. The manufacturer also
recommends that any soluble oil inhibitor is
NOT used for this equipment.
Do not remove the radiator pressure cap while
the engine is hot or serious burns from boiling
liquid or steam could result.
Ethylene glycol base antifreeze is poisonous.
Do not use mouth to siphon coolant from the
radiator, recovery bottle or any container. Wash
hands thoroughly after handling. Never store
used antifreeze in an open container because
animals are attracted to the smell and taste of
antifreeze even though it is poisonous to them.
