out 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 care-
lessly. 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

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

The operator (driver) is responsible for proper and
safe use of the vehicle and its equipment, and the
safety of all vehicle occupants. We strongly recom-
mend that the operator read this manual and thor-
oughly understand all instructions before using this
equipment. We also strongly recommend instructing
other occupants in the vehicle to properly start and
operate the generator. This prepares them if they
need to operate the equipment in an emergency.
CONTENTS
This manual contains pertinent owners information,
including warranty, electrical diagrams, exploded
views and lists of repair parts for generator model
numbers 009600-5 and 009734-5. In addition, the

OPERATION AND MAINTENANCE
It is the operator's responsibility to perform all safe-
ty 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 ser-
vice 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 your generator
ensure a minimum number of problems and keep
operating expenses at a minimum. See your Generac
Authorized Service Dealer for service aids and acces-
sories.
