INTRODUCTION

Thank you for purchasing the Modular Power System
by Generac Power Systems.

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 Generac 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 person-
nel to special instructions about a particular service or
operation that may be hazardous if performed incor-
rectly or carelessly. Observe them carefully. Their defi-
nitions are as follows:

After this heading, read instructions that, if not
strictly complied with, will result in personal injury
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 informa-
tion 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. Generac strongly recommends that
the operator read this Owner's Manual and thor-
oughly understand all instructions before using this
equipment. Generac 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 a Generac
Authorized Service Dealer. Normal maintenance serv-
ice 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
contribute to the need for maintenance service.

Proper maintenance and care of the generator(s)
ensures a minimum number of problems and keep
operating expenses at a minimum. See a Generac
Authorized Service Dealer for service aids and acces-
sories.

Operating instructions presented in this manual
assume that the standby electric system has been
installed by a Generac 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,
contact a Generac Authorized Service Dealer for
assistance. Service technicians are factory-trained
and are capable of handling all service needs.

When contacting a Generac Authorized Service
Dealer about parts and service, always supply the
complete model number of the unit as given on the
DATA CARD affixed to the unit.
