SAFETY 00
Safety Notice 00
General Precautions 00
Mistakes in operation are extremely dangerous. Read the
Operation & Maintenance Manual carefully BEFORE
operating the machine. In addition, read this manual and
understand its contents before starting the work.
1. Before carrying out any greasing or repairs, read all the
precautions given on the labels which are fixed to the
machine. For the locations of the safety labels and a
detailed explanation of precautions, see the Operation &
Maintenance Manual.
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,
shielding goggles, 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; learn the correct way
to use them; and use the proper ones. Before starting
work, thoroughly check the tools, machine, forklift,
service car, etc.
6. Only qualified workers must carry out work and
operations which require license or qualification.
7. 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.
8. Avoid continuing work for long hours and take rests at
proper intervals to keep your body in good condition.
Take rests in specified safe places.
Safety Points
Important Safety Notice 00
Proper service and repair is extremely important for the safe operation of your machine. The service and repair techniques
recommended and described in this manual are both effective and safe methods of operation. Some of these operations
require the use of tools specially designed for the purpose.
To prevent injury to workers, the symbols and are used to mark safety precautions in this manual. The cautions
accompanying these symbols should always be followed carefully. If any dangerous situation arises or may possibly arise,
first consider safety, and take the necessary actions to deal with the situation.
WARNING! Never modify, weld, cut, or drill
on any part of a ROPS
structure. Doing so may
weaken the structure which
could lead to possible failure in
a rollover situation

4. FOREWORD SAFETY
00-4 ➁
Preparations for Work 00
1. Before adding oil or making repairs, park the machine
on hard, level ground, and block the wheels or tracks to
prevent the machine from moving.
2. 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 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, 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 00
1. 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 release the pressure completely from
the circuit.
2. The coolant and oil in the circuits are hot when the
engine is stopped; be careful not to get burned. Wait for
the oil and coolant to cool before carrying out any work
on the oil or water circuits.
3. Before starting work, remove the leads from the battery.
ALWAYS remove the lead from the negative (-)
terminal first.
4. When raising heavy components (in excess of 25 kg
(55 lb)), 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
hitting any other part. Do not work with any part still
raised by the hoist or crane.
5. When removing a cover which is under internal pressure
or under pressure from a spring, always leave two bolts
in position on opposite sides. Loosen the bolts gradually
and alternately to release the pressure, and then remove
the cover.
6. When removing components, be careful not to break or
damage the wiring, Damaged wiring may cause
electrical fires.
7. When removing piping, stop the fuel or oil from spilling
out. If any fuel or oil drips on the floor, wipe it up
immediately. Fuel or oil on the floor can cause you to
slip, or can even start fires.
8. Gasoline or other fuels should never be used to clean
parts. Clean parts with appropriate solvents.
9. Be sure to assemble all parts again in their original
places. Replace any damaged parts or parts that must not
be reused 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.
10. When installing high pressure hoses, make sure that
they are not twisted. Damaged tubes are dangerous, so
be extremely careful when installing tubes for high
pressure circuits. Also check that connecting parts are
correctly installed.
11. 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.
12. When aligning two holes, never insert your fingers or
hand. Be careful not to get your fingers caught in a hole.
13. When measuring hydraulic pressure, check that the
measuring tool is correctly assembled before taking any
measurements.
14. Take care when removing or installing the tracks of
track-type machines. When removing the track, the
track separates suddenly; never let anyone stand at
either end of the track.
15. When jump-starting the machine, only use a machine of
similar size and voltage. Never use an arc welder or
other electrical generating equipment to jump-start the
machine. Carefully review the safety procedures for
jump starting the machine.
16. Before starting work, stop the engine. When working on
or around a rotating part, stop the engine. When
checking the machine without stopping the engine
(measuring oil pressure, revolving speed, temperature,
etc.), be extremely careful not to get rolled or caught in
rotating or moving parts.
17. If the engine is operated for a long time in a place which
is not ventilated well, you may suffer from gas
poisoning. Before starting the engine, open the windows
and doors so that the area is well ventilated.
