INTRODUCTION

Thank you for purchasing this model of the standby 
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 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 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 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 work-
manship 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 a Service Dealer for ser-
vice aids and accessories.

Operating instructions presented in this manual 
assume that the standby 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 capa-
ble of handling all service needs.

When contacting a Service Dealer 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.
