INTRODUCTION

Thank you for purchasing this model of the Guardian product line 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, acoustical metal
enclosure that is intended exclusively for outdoor installation. This
generator will operate using either vapor withdrawn liquid propane
(LP) or natural gas (NG).

READ THIS MANUAL THOROUGHLY

If you do not understand any portion of this manual, contact Generac
or your nearest Generac/Guardian Authorized 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 you to special instruction about a particular operation
that may be hazardous if performed incorrectly or carelessly.
Observe them carefully. Their definitions are as follows:

After this heading, you can read instructions that, if not strictly
complied with, will result in personal injury or property damage.

After this heading, you can read instructions that, if not strictly
complied with, may result in personal injury or property damage.

After this heading, you can read instructions that, if not strictly
complied with, could result in damage to equipment and/or property.
NOTE: After this heading, you can read explanatory statements
that require special emphasis.

These safety warnings cannot eliminate the hazards that they
indicate. Common sense and strict compliance 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 follows:

This symbol points out important safety information that, if

not followed, could endanger personal safety and/or
property of you and others.

This symbol points out potential explosion hazard.

This symbol points out potential fire hazard.

This symbol points out potential electrical shock hazard.

SAVE THESE INSTRUCTIONS – The manufacturer suggests

that these rules for safe operation be copied and posted
near the unit’s installation site. Safety should be stressed to
all operators and potential operators of this equipment.

Study these 

SAFETY RULES

carefully before installing, operating or

servicing this equipment. Become familiar with this 

Owner’s Manual

and with the unit. The generator can operate safely, efficiently and
reliably only if it is properly installed, operated and maintained. Many
accidents are caused by failing to follow simple and fundamental
rules or precautions.

Generac cannot possibly anticipate every possible circumstance 
that might involve a hazard. The warnings in this manual, and on 
tags and decals affixed to the unit are, therefore, not all-inclusive. If
you use a procedure, work method or operating technique Generac
does not specifically recommend, you must satisfy yourself that it is
safe for you and others. You also must make sure the procedure,
work method or operating technique that you choose does not 
render the generator unsafe.

Despite the safe design of this generator, operating this 
equipment imprudently, neglecting its maintenance or being 
careless can cause possible injury or death. Permit only 
responsible and capable persons to operate or maintain this 
equipment.

Potentially lethal voltages are generated by these machines.
Ensure all steps are taken to render the machine safe before 
attempting to work on the generator.

Parts of the generator are rotating and/or hot during operation.
Exercise care near running generators.

The engine exhaust from this product contains chemicals known 
to the state of California to cause cancer, birth defects or other
reproductive harm.
