PREFACE

This manual has been prepared by the Yamaha Motor Company, Ltd. 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 understanding 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.
