GENERAL PRECAUTIONS
Mistakes in operation are extremely dangerous.
Read the Operation and Maintenance Manual
carefully BEFORE operating the machine.
1. Before carrying out any greasing or repairs,
read all the precautions given on the decals
which are fixed to the machine.
2. When carrying out any operation, always
wear safety shoes and helmet. Do not wear
loose work clothes, or clothes with buttons
missing.
• Always wear safety glasses when hitting
parts with a hammer.
• Always wear safety glasses when grind-
ing parts with a grinder, etc.
3. If welding repairs are needed, always have a
trained, experienced welder carry out the
work. When carrying out welding work, al-
ways wear welding gloves, apron, hand
shield, cap and other clothes suited for weld-
ing work.
4. When carrying out any operation with two
or more workers, always agree on the oper-
ating procedure before starting. Always in-
form your fellow workers before starting any
step of the operation. Before starting work,
hang UNDER REPAIR signs on the controls
in the operator's compartment.
5. Keep all tools in good condition and learn
the correct way to use them.
6. Decide a place in the repair workshop to
keep tools and removed parts. Always keep
the tools and parts in their correct places.
Always keep the work area clean and make
sure that there is no dirt or oil on the floor.
Smoke only in the areas provided for smok-
ing. Never smoke while working.
PREPARATIONS FOR WORK
7. Before adding oil or making any repairs,
park the machine on hard, level ground, and
block the wheels or tracks to prevent the
machine from moving.
8. Before starting work, lower blade, ripper,
bucket or any other work equipment to the
ground. If this is not possible, insert the
safety pin or use blocks to prevent the work
equipment from falling. In addition, be sure
to lock all the control levers and hang warn-
ing signs on them.
9. When disassembling or assembling, support
the machine with blocks, jacks or stands
before starting work.
10. Remove all mud and oil from the steps or
other places used to get on and off the ma-
chine. Always use the handrails, ladders or
steps when getting on or off the machine.
Never jump on or off the machine. If it is
impossible to use the handrails, ladders or
steps, use a stand to provide safe footing.
Proper service and repair is extremely important for safe machine operation. The
service and repair techniques recommended by Komatsu and described in this manual
are both effective and safe. Some of these techniques require the use of tools specially
designed by Komatsu for the specific purpose.
To prevent injury to workers, the symbol ¤ is used to mark safety precautions in this
manual. The cautions accompanying these symbols should always be followed care-
fully. If any dangerous situation arises or may possibly arise, first consider safety, and
take the necessary actions to deal with the situation.

PRECAUTIONS DURING WORK
11. When removing the oil filler cap, drain plug
or hydraulic pressure measuring plugs,
loosen them slowly to prevent the oil from
spurting out.
Before disconnecting or removing compo-
nents of the oil, water or air circuits, first
remove the pressure completely from the
circuit.
12. The water and oil in the circuits are hot
when the engine is stopped, so be careful
not to get burned.
Wait for the oil and water to cool before
carrying out any work on the oil or water
circuits.
13. Before starting work, remove the leads from
the battery. Always remove the lead from
the negative (–) terminal first.
14. When raising heavy components, use a hoist
or crane.
Check that the wire rope, chains and hooks
are free from damage.
Always use lifting equipment which has
ample capacity.
Install the lifting equipment at the correct
places. Use a hoist or crane and operate
slowly to prevent the component from hit-
ting any other part. Do not work with any
part still raised by the hoist or crane.
15. When removing covers which are under in-
ternal pressure or under pressure from a
spring, always leave two bolts in position
on opposite sides. Slowly release the pres-
sure, then slowly loosen the bolts to remove.
16. When removing components, be careful not
to break or damage the wiring. Damaged
wiring may cause electrical fires.
17. When removing piping, stop the fuel or oil
from spilling out. If any fuel or oil drips onto
the floor, wipe it up immediately. Fuel or oil
on the floor can cause you to slip, or can
even start fires.
18. As a general rule, do not use gasoline to
wash parts. In particular, use only the mini-
mum of gasoline when washing electrical
parts.
19. Be sure to assemble all parts again in their
original places.
Replace any damaged parts with new parts.
• When installing hoses and wires, be sure
that they will not be damaged by contact
with other parts when the machine is be-
ing operated.
20. When installing high pressure hoses, make
sure that they are not twisted. Damaged
tubes are dangerous, so be extremely care-
ful when installing tubes for high pressure
circuits. Also, check that connecting parts
are correctly installed.
21. When assembling or installing parts, always
use the specified tightening torques. When
installing protective parts such as guards,
or parts which vibrate violently or rotate at
high speed, be particularly careful to check
that they are installed correctly.
22. When aligning two holes, never insert your
fingers or hand. Be careful not to get your
fingers caught in a hole.
23. When measuring hydraulic pressure, check
that the measuring tool is correctly assem-
bled before taking any measurements.
24. Take care when removing or installing the
tracks of track-type machines.
When removing the track, the track sepa-
rates suddenly, so never let anyone stand at
either end of the track.

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.
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" 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.
MAINTENANCE STANDARD
This section gives the judgement standards when inspecting disassembled parts.
The specifications contained in this shop manual are subject to change at any
time and without any advance notice. Use the specifications given in the book
with the latest date.
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.
FOREWORD GENERAL
6. 00-6
Shop manuals are issued as a guide to carrying
out repairs. They are divided as follows:
Chassis volume: Issued for every machine model
Engine volume: Issued for each engine series
Electrical volume:
Attachments volume:
These various volumes are designed to avoid
duplicating the same information. Therefore, to
deal with all repairs for any model , it is neces-
sary that chassis, engine, electrical and attach-
ment volumes be available.
DISTRIBUTION AND UPDATING
Any additions, amendments or other changes
will be sent to KOMATSU distributors. Get the
most up-to-date information before you start any
work.
FILING METHOD
