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. In addition, this section may contain hydraulic circuit diagrams, electric circuit diagrams, and maintenance standards.
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” with “Causes” are also included in this section.
DISASSEMBLY AND ASSEMBLY
This section explains the procedures for removing, installing, disassembling and assembling each component, as well as precautions for them.
MAINTENANCE STANDARD
This section gives the judgment standards for inspection of disassembled parts. The contents of this section may be described in STRUCTURE AND FUNCTION.
OTHERS
This section mainly gives hydraulic circuit diagrams and electric circuit diagrams. In addition, this section may give the specifications of attachments and options together.
