by Yamaha dealers and their qualified mechan-
ics. It is not possible to put an entire mechan-
ic’s education into one manual, so it is
assumed that persons using this book to per-
form maintenance and repairs on Yamaha
Multi-Purpose Engine have a basic under-
standing of the mechanical precepts and pro-
cedures inherent to Multi-Purpose Engine
repair technology. Without such knowledge,
attempted repairs or service to this model may
render it unfit for use and/or unsafe.
Yamaha Motor Powered Products Co., Ltd. is
continually striving to further improve all mod-
els manufactured by Yamaha. Modifications
and significant changes in specifications or
procedures will be forwarded to all Authorized
Yamaha dealers and will, where applicable,
appear in future editions of this manual.
