INTRODUCTION
Thank you for purchasing this model of the stationary emergency
generator 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 nearest
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 service are essential to prevent-
ing accidents.
Four commonly used safety symbols accompany the DANGER,
WARNING and CAUTION 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.
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.
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 a
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 con-
tribute 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 a Service Dealer for service aids and accessories.
Operating instructions presented in this manual assume that the
generator electric system has been installed by a 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
a 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.
