INTRODUCTION:

• To insure a long life for the machine and the engine and to prevent failure and problems,
  proper operation, maintenance and repairs are indispensable.
• This service manual includes an “outline,” “structure and operation,” “inspection and
  adjustment,” “disassembly and assembly,” “standard maintenance,” and “repair and replacement
  of parts” of the machine which are necessary to carry out the inspections and
  repairs in the repair shop.
• We hope that this manual helps you to efficiently and effectively carry out repairs by
  providing and accurate description of the product and the correct repair techniques.

PRECAUTIONS ON MAINTENANCE:
1. Correct operation:
Correct operation means to follow the correct “procedure” and “method.”
Procedure focuses on speed and accuracy of each job.
In the method, are addressed what type of facility, tools, instruments, materials, oil should
be used, how and which part should be checked, adjusted or disassembled, and what
matters to attend to.
2. Precautions on operation:
1. Safety check
Check that stoppers and sleepers are correctly installed for the vehicle jack-up
operation.
2. Preparation
Prepare all of the tools and inspect and adjust the instruments.
3. For efficiency
1) Understand the state before disassembly.
What is the problem? Is disassembly absolutely necessary?
2) Before disassembly
Determine whether match marks are necessary. For the electrical system, disconnect
the cable from the battery terminal.
3) Precautions for disassembly:
In stead of checking all of the disassembled parts at once, check each part
individually as it is disassembled. When removing the hydraulic unit or the hoses,
mount a dust cap on the connection.
4) Repair of disassembled parts
Keep the disassembled parts in order. Clearly distinguish the parts to be replaced
with new parts from those to be reused. Packings, seals, rings, split pins must be
replaced.
