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, contact the near-
est Authorized Service Dealer for starting, 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 personnel to special instructions about a particular
service or operation that may be hazardous if performed incor-
rectly or carelessly. Observe them carefully. Their definitions are
as follows:
INDICATES A HAZARDOUS SITUATION OR
ACTION WHICH, IF NOT AVOIDED, WILL RESULT
IN DEATH OR SERIOUS INJURY.
Indicates a hazardous situation or action which,
if not avoided, could result in death or serious
injury.
Indicates a hazardous situation or action which,
if not avoided, could result in minor or moderate
injury.
NOTE:
Notes contain additional information important to a procedure
and will be found within the regular text body of this manual.
These safety warnings cannot eliminate the hazards that they
indicate. Common sense and strict compliance with the special
instructions while performing the action or service are essential to
preventing accidents.
Four commonly used safety symbols accompany the DANGER,
WARNING CAUTION and blocks. The type of information each
indicates is as follows:
n
This symbol points out important safety
information 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 equip-
ment. The manufacturer strongly recommends that the operator
read this Owner's Manual and thoroughly understand all instruc-
tions before using this equipment. The manufacturer also strongly
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 workman-
ship 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-yourselfproject.
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 a dealer about parts and service, always supply
the complete Model Number, Serial Number and Type Code (where
applicable) from the DATA LABEL that is affixed to the unit.

The Maintenance Disconnect Switch and the
AUTO/OFF/MANUAL switches (if so equipped)
must be set properly, or the generator will
crank and start as soon as the utility power to
the transfer switch is turned off. Refer to appli-
cable control panel and transfer switch manuals
for more information.
n
Do not proceed until certain that utility source
voltage is available to the transfer switch and
the transfer switch main contacts are set to
UTILITY.
Do not attempt manual operation until all
power supplies to the transfer switch have been
positively turned off, or extremely dangerous -
possibly lethal - electrical shock will result.
Transfer switch enclosure doors should be kept
closed and locked. Only authorized personnel
should be allowed access to the transfer switch
interior. Extremely high and dangerous voltages
are present in the transfer switch.
nDo not crank the engine continuously for lon-
ger than 30 seconds, or the heat may
damage the starter motor.
