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-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 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.

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.
