Safety notice
Important Safety Notice
Proper service and repair is extremely important for safe
machine operation. Some of the described service and re-
pair 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 ac-
companying these symbols must 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.
General Precautions
Mistakes in operation are extremely dangerous. Read the
OPERATION AND MAINTENANCE MANUAL carefully before
operating the machine! Always follow the safety rules valid
in your country carefully!
1. Before carrying out any greasing or repairs, read all the pre-
cautions 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 grinding parts with a
grinder, etc.
3. If welding repairs are needed, always have a trained, experi-
enced welder carry out the work. When carrying out welding
work, always wear welding gloves, apron, glasses, cap and
other clothes suited for welding work.
4. When carrying out any operation with two or more workers,
always agree on the operating procedure before starting. Al-
ways inform 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 re-
moved 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. Never smoke while
working. Smoke only in the areas provided for smoking.
Preparations for work
1. Before adding oil or making any repairs, park the machine
on hard, level ground, and block the wheels or tracks to pre-
vent the machine from moving.
2. Before starting work, lower blade, ripper, bucket or any other
work equipment to the ground and install the safety bar on
the frame. If this is not possible, insert the safety pin or use
blocks to prevent the work equipment from falling. In addi-
tion, be sure to lock all the control levers and hang warning
signs on them.
3. When disassembling or assembling, support the machine
with blocks, jacks or stands before starting work.
4. Remove all mud and oil from the steps or other places used
to get on and off the machine. Always use the handrails, lad-
ders 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 foot-
ing.
