1 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 sections. These sections are further divided into each main group of components.
GENERAL:
This section lists the general machine dimensions, performance specifications, component weights, and fuel, coolant and lubricant specification charts.
STRUCTURE, FUNCTION AND MAINTENANCE STANDARD:
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 gives the judgement standards when inspecting disassembled parts.
STANDARD VALUE TABLE:
This section explains the standard values for new machine and judgement criteria for testing, adjusting and troubleshooting. This standard value table is used to check the standard values in testing and adjusting and to judge parts in 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:
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.
OTHERS:
This section has the foldout drawings for the machine.
