Introduction

This Operation Manual contains the information you will

need to operate the engine correctly. Check that you have the
correct Operation Manual for your engine.

Read the book carefully before operating or servicing

the engine.

 Incorrect operation or servicing of the engine

could result in personal injury or material damage as well as
damaging the engine itself. 

If you do not understand or are

uncertain on any operation in this book, contact your
dealer who can explain or demonstrate the procedure for
you.

Warning and Caution

In this manual and on the engine you will find the follow-

ing special warning symbols.
