2.1 REPLACEMENT PARTS AND
WARRANTY INFORMATION
The replacement of any part with any other than a Sky
Trak authorized replacement part can adversely affect
the safety, performance, or durability of the vehicle, and
may void the warranty. Sky Trak International assumes
no liability whatsoever for unauthorized replacement
parts.
A warranty registration form must be filled out by the Sky
Trak distributor, signed by the purchaser, and returned to
Sky Trak when the vehicle is sold and/or put into use.
Registration activates the warranty period and helps to
assure that warranty claims are promptly processed. To
guarantee full warranty service, verify that the distributor
has returned the business reply card of the warranty reg-
istration form to Sky Trak.
2.2 SERIAL NUMBER LOCATIONS
When ordering replacement parts or making service
inquiries about the vehicle, various serial numbers are
required to help assure the provision of
correct parts and information. Before ordering parts or
initiating service inquiries, make note of the pertinent
serial numbers.
