FOREWORD
GENERAL

• This shop manual has been prepared as an aid to improve the quality of repairs by giving the
  serviceman an accurate understanding of the product and by showing him the correct way to perform
  repairs and make judgements. Make sure you understand the contents of this manual and use it to full
  effect at every opportunity.
• This shop manual mainly contains the necessary technical information for operations performed in a
  service workshop. For ease of understanding, the manual is divided into the following chapters; these
  chapters are further divided into the each main group of components.

STRUCTURE AND FUNCTION
This section explains the structure and function of each component. It serves not only to give
an understanding of the structure, but also serves as reference material for troubleshooting.
TESTING AND ADJUSTING
This section explains checks to be made before and after performing repairs, as well as
adjustments to be made at completion of the checks and repairs.
Troubleshooting charts correlating “Problems” to “Causes” are also included in this section.
DISASSEMBLY AND ASSEMBLY
This section explains the order to be followed when removing, installing, disassembling or
assembling each component, as well as precautions to be taken for these operations.
MAINTENANCE STANDARD
This section gives the judgement standards when inspecting disassembled parts.
