INTRODUCTION
Thank you for purchasing this model by Generac
Power Systems Inc.. This model is a compact, high
performance, air-cooled, engine-driven generator
designed to automatically supply electrical power to
operate critical loads during a utility power failure.
This unit is factory installed in an all-weather, metal
enclosure that is intended exclusively for outdoor instal-
lation. This generator will operate using either vapor
withdrawn liquid propane (LP) or natural gas (NG).

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 opera-
tion that may be hazardous if performed incorrectly
or carelessly. Observe them carefully. Their defini-
tions are as follows:

that they indicate. Common sense and strict compli-
ance with the special instructions while performing
the service are essential to preventing accidents.
