Introduction
We want you to be completely satisfied with your

Authorized Service Dealer for help with service,

Whenever you contact your Authorized Service
Dealer or the factory, always know the model and
serial numbers of your product. These numbers will
help the Service Dealer or Service Representative
provide exact information about your specific
product. You will find the model and serial number
plate located in a unique place on the product as

.
The warning system in this manual identifies
potential hazards and has special safety messages that
help you and others avoid personal injury, even death.
DANGER, WARNING and CAUTION are signal
words used to identify the level of hazard. However,
regardless of the hazard, be extremely careful.
DANGER signals an extreme hazard that will cause
serious injury or death if the recommended
precautions are not followed.
WARNING signals a hazard that may cause serious
injury or death if the recommended precautions are
not followed.
CAUTION signals a hazard that may cause minor or
moderate injury if the recommended precautions are
not followed.
Two other words are also used to highlight
information. “Important” calls attention to special
mechanical information and “Note” emphasizes
general information worthy of special attention.
