FOREWORD
- 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 chapters for each main group of components; these chapters are further divided into the following sections.
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.
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.
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.
This section gives the judgement standards when inspecting disassembled parts.
