Important safety notice
Proper service and repair are 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

k
k
is used to mark safety precautions in this manual. The
cautions accompanying these symbols should always be followed carefully. If any dangerous situa-
tion arises or may possibly arise, first consider safety, and take the necessary actions to deal with
the situation.
1.
General precautions
k
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 safety plates stuck to
the machine. For the locations of the
safety plates and detailed explanation of
precautions, see the Operation and Main-
tenance Manual.
2)
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, water,
or oil on the floor. Smoke only in the areas
provided for smoking. Never smoke while
working.
3)
When carrying out any operation, always
wear safety shoes and helmet. Do not
wear loose work clothes, or clothes with
buttons missing.
q
Always wear safety glasses when hit-
ting parts with a hammer.
q
Always wear safety glasses when
grinding parts with a grinder, etc.
4)
When carrying out any operation with 2 or
more workers, always agree on the oper-
ating procedure before starting. Always
inform your fellow workers before starting
any step of the operation. Before starting
work, hang UNDER REPAIR warning
signs in the operator's compartment.
5)
Only qualified workers must carry out work
and operation which require license or
qualification.
6)
Keep all tools in good condition, learn the
correct way to use them, and use the
proper ones of them. Before starting work,
thoroughly check the tools, machine, fork-
lift, service car, etc.
7) If welding repairs are needed, always
have a trained and experienced welder
carry out the work. When carrying out
welding work, always wear welding
gloves, apron, shielding goggles, cap and
other clothes suited for welding work.
8) Before starting work, warm up your body
thoroughly to start work under good condi-
tion.
2.
Preparations for work
1) Before adding oil or making any repairs,
park the machine on hard and level
ground, and apply the parking brake and
block the wheels or tracks to prevent the
machine from moving.
2) Before starting work, lower the work
equipment (blade, ripper, bucket, etc.) to
the ground. 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 warning signs on them.
