SAFETY NOTICE
IMPORTANT SAFETY NOTICE
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 k is used to mark safety precautions in this manual.
The cautions accompanying these symbols should always be followed carefully. If any danger-
ous 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 care-
fully 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 grinding
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, always wear
welding gloves, apron, hand shield, 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. Always 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 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 smoking. Never smoke while work-
ing.
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 fall-
ing. In addition, be sure to lock all the control
levers and hang warning 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 machine.
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 pro-
vide safe footing.
SAFETY SAFETY NOTICE
00-4
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 components
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 carry-
ing 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 nega-
tive (–) 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 pre-
vent the component from hitting any other part.
Do not work with any part still raised by the hoist
or crane.
15.When removing covers which are under internal
pressure or under pressure from a spring,
always leave two bolts in position on opposite
sides. Slowly release the pressure, 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 minimum of
gasoline when washing electrical parts.
19.Be sure to assemble all parts again in their origi-
nal 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 being
operated.
20.When installing high pressure hoses, make sure
that they are not twisted. Damaged tubes are
dangerous, so be extremely careful when install-
ing 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 par-
ticularly careful to check that they are installed
correctly.
22.When aligning two holes, never insert your fin-
gers 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 assembled before
taking any measurements.
24.Take care when removing or installing the tracks
of track-type machines.
When removing the track, the track separates
suddenly, so never let anyone stand at either
end of the track.
