INTRODUCTION
Thank you for purchasing this Guardian model by Generac
Power Systems Inc.. This model is a compact, high per-
formance, 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 installation. This genera-
tor will operate using either vapor withdrawn liquid propane (LP)
or natural gas (NG).
This unit meets the 1998 and later California emissions reg-
ulations. To ensure that the engine continues to meet these
regulations, refer to the following information and instruc-
tions in this owner’s manual.

Period referred to on the Emissions Compliance label indi-
cates the number of operating hours for which the engine
has been shown to meet federal emission requirements.

125 hours, B = 250 hours, and A = 500 hours.
For engines 225 cc or more, Category C = 250 hours, B =
500 hours, and A = 1000 hours.

Throughout this publication, and on tags and

cial instructions about a particular operation that may be
