NOTICE
This manual has been prepared by the Yamaha Motor Company primarily for use by Yamaha
dealers and their trained mechanics when performing maintenance procedures and repairs to
Yamaha equipment. It has been written to suit the needs of persons who have a basic under-
standing of the mechanical and electrical concepts and procedures inherent in the work, for
without such knowledge attempted repairs or service to the equipment could render it unsafe
or unfit for use.
Because the Yamaha Motor Company Ltd. has a policy of continuously improving its prod-
ucts, models may differ in detail from the descriptions and illustrations given in this publica-
tion. Use only the latest edition of this manual. Authorized Yamaha dealers are notified
periodically of modifications and significant changes in specifications and procedures, and
these are incorporated in successive editions of this manual.
