NOTICE

This manual has been prepared by Yamaha primarily for use by Yamaha dealers and their trained

mechanics when performing maintenance procedures and repairs to Yamaha equipment. It has

repairs or service to the equipment could render it unsafe or unfit for use.

from the descriptions and illustrations given in this publication. 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.
