k IMPORTANT SAFETY NOTICE
Proper service and repair is extremely important for the safe operation of your machine.
The service and repair techniques recommended by Komatsu Utility and describe in this manual are both ef-
fective and safe methods of operation. Some of these operations require the use of tools specially designed
by Komatsu Utility for the 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 carefully followed. If any danger arises or may possibly arise,
first consider safety, and take necessary steps to face.
GENERAL PRECAUTIONS
Mistakes in operation extremely dangerous.
Read all the Operation and Maintenance Manual carefully
BEFORE operating the machine.
1. Before carrying out any greasing or repairs, read all
the precautions written on the decals which are suck
on 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,
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 be-
fore starting. Always inform your fellow workers be-
fore 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 working.
PREPARATIONS FOR WORK
7. Before adding or making any repairs, park the ma-
chine on hard, level ground, and block the wheels to
prevent the machine from moving.
8. Before starting work, lower outrigger, bucket or any
other work equipment to the ground. If this is not pos-
sible, use blocks to prevent the work equipment from
falling down. In addition, be sure to lock all the control
levers and hang warning sign on them.
9. When disassembling or assembling, support the ma-
chine 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 provide safe footing.
PRECAUTIONS DURING WORK
11. When removing the oil filler cap, drain plug or hydrau-
lic pressure measuring plugs, loosen them slowly to
prevent the oil from spurting out.
Before disconnecting or removing components of the
hydraulic circuit and engine cooling circuit, first re-
move the pressure completely from the circuit.
12. The water and oil in the circuits are not hot when the
engine in stopped, so be careful not to get burned.
Wait for the oil water to cool before carrying out any
work on the cooling water circuits.
13. Before starting work, remove the leads from the bat-
tery. Always remove the lead from the negative ( – )
terminal first.
k SAFETY
WH6-1E0 WH7-1E0
00-6
k SAFETY
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 ca-
pacity. Install the lifting equipment at the correct
places.
Use a hoist or crane and operate slowly to prevent
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.
Damage wiring may cause electrical fires.
17. When removing piping, stop the fuel or oil from spill-
ing out. If any fuel or oil drips on to 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 original
places. Replace any damage 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 dan-
gerous, so be extremely careful when installing
tubes for high pressure circuits. Also, check that
connecting parts are correctly tightened.
21. When assembling or installing parts, always use
specified tightening torques.
When installing the parts which vibrate violently or
rotate at high speed, be particulary careful to check
that they are correctly installed.
22. When aligning two holes, never insert your fingers or
hand.
23. When measuring hydraulic pressure, check that the
measuring tool is correctly assembled before taking
any measurement.
24. Take sure when removing or installing wheels.
