INTRODUCTION

Thank you for purchasing this model of the QuietSource standby generator set product line by Generac Power Systems.

Every effort was expended to make sure that the information and instructions in this manual are both accurate and current at the time the manual was writ- ten. 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:

DANGER

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-

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 ensures a minimum number of problems and keep operating expenses at a minimum. See the Generac Authorized Service Dealer for service aids and accessories.

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.
