AND FUNCTION” is helpful in not only understanding the structure of each component but performing
troubleshooting.
20 STANDARD VALUE TABLE
This section describes the standard values for new machine and failure criteria for testing and adjusting, and
troubleshooting. Use the standard values table to check the standard values for testing and adjusting, and judge
troubles in troubleshooting.
30 TESTING AND ADJUSTING
This section describes the measuring tools and measuring methods for testing and adjusting as well as the adjusting
method of each part. The standard values and repair limit for TESTING AND ADJUSTING are described
in “STANDARD VALUE TABLE”.

disassembly, and assembly of the components and parts. In addition, tightening torques, quantity, and
weight of the coating materials, lubricants, and coolant necessary to these works are shown.
60 MAINTENANCE STANDARD
This section describes the maintenance standard value of each component. The maintenance standard shows
the criteria and remedies for disassembly and assembly.
80 THE OTHER INFORMATION
This section describes the structure and function, testing and adjusting, and troubleshooting for all of the other
components or equipment which cannot be separately classified in the appendix.
90 Circuit diagrams
This section describes hydraulic circuit diagrams and electrical circuit diagrams.

General precautions
If the machine is handled incorrectly, it is dangerous. Read and understand what is described in the
operation and maintenance manual before operation. Read and understand what is described in this
manual before operation.
• Read and understand the meaning of all the safety labels stuck to the machine before performing any
greasing or repairs. For the locations of the safety labels and detailed explanation of precautions, see Operation
and Maintenance Manual.
• Tools and removed parts in the workshop should be well organized. Always keep the tools and parts in their
correct places. Always keep the work area clean and make sure that there is no dust, dirt, oil, or water on
the floor. Smoke only in the designated areas. Never smoke while working.
• Keep all tools in good condition, learn the correct way to use them, and use the proper ones. Check the
tools, machine, forklift truck, service car, etc. thoroughly before starting the work.
• Always wear safety shoes and helmet when performing
any operation. Do not wear loose clothes, or clothes with
buttons missing.
• Always wear the protective eyeglasses when hitting parts
with a hammer.
• Always wear the protective eyeglasses when grinding
parts with a grinder, etc.
• When performing any operation with multiple workers, always
agree on the operating procedure before starting. Be
clear in verbal communication, and observe hand signals.
Hang “UNDER REPAIR” warning tag in the operator’s
compartment Before starting work.
• Work and operation which require license or qualification
should be performed by qualified workers.
• Welding repairs should be performed by trained and experienced welders. When performing welding work,
always wear welding gloves, apron, welding goggles, cap and other clothes suited for welding work.
• Warm up before starting the work with exercise which increases alertness and the range of motion in order
to prevent injury.
• Avoid prolonged work, and take a rest at times to keep up a good condition. Take a rest at designated safe
area.
Precautions for preparatory work:
• Place the machine on a firm and level ground, and apply the parking brake and chock the wheels or tracks
to prevent the machine from moving before adding oil or making any repairs.
• Lower the work equipment (blade, ripper, bucket, etc.) to the ground before starting work. If this is not possible,
insert the lock pin or use blocks to prevent the work equipment from falling. In addition, be sure to
lock all the control levers and hang “UNDER REPAIR” warning tag on them.
• When performing the disassembling or assembling work, support the machine securely with blocks, jacks,
or stands before starting the work.
• Remove all mud and oil from the steps or other places for going up and down on the machine. Always use the handrails, ladders or steps when for going up and down on the machine. Never jump on or off the machine. When the scaffold is not provided, use steps or stepladder to secure your footing. Do not use handrails, ladders, or steps if they are damaged or deformed. Repair it or replace it immediately.
