00SAFETY
00SAFETY NOTICE
00GENERAL PRECAUTIONS
Mistakes in operation are extremely costly and dangerous.
Read the OPERATION & MAINTENANCE MANUAL
carefully BEFORE operating the machine.
1. Before carrying out any greasing or repairs, read all the
precautions given on the decals attached to the machine.
2. When carrying out any operation, always wear proper
safety equipment specified for the operation you are
performing. Do not wear loose fitting work clothes, or
clothes with buttons missing.
• Always wear safety glasses when striking 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 operations, 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. Always inform your fellow workers
before starting any step of the operation. Before starting
work, lock and tag all controls in the operator’s compart-
ment.
5. Keep all tools in good condition.
6. Decide on 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 there is no dirt or oil on the floor. Smoke
only in the areas provided for smoking. Never smoke
while working.
00PREPARATIONS FOR WORK
1. Before adding oil or making repairs, park the machine
on hard, level surface, and block the wheels or tracks to
prevent the machine from moving. Lower all work
impliments to the ground and remove iginition key
2. Before starting work, lower blade, ripper, bucket or any
other work equipment to the ground. If this is not possi-
ble, 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.
00PRECAUTIONS DURING WORK
1. When removing the oil filler cap, drain plug or hydrau-
lic pressure measuring plugs, loosen them slowly to pre-
vent the oil from spurting out. Before disconnecting or
removing components of the oil, coolant or air circuits,
first relive the pressure completely from the circuit.
2. The coolant and oil in the systems are hot when the
engine is stopped, so be careful not to get burned. Wait
for the oil and coolant to cool before carrying out any
work on the oil or coolant systems.
3. Before starting work, remove the leads from the battery.
ALWAYS remove the lead from the negative (-) termi-
nal first.
00IMPORTANT SAFETY NOTICE
Proper service and repair is extremely important for the safe operation of your machine. The service and repair procedures
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 accom-
panying these symbols should always be followed carefully. If any dangerous situation arises or may possibly arise, first con-
sider safety, and take the necessary actions to deal with the situation.
4. FOREWORD SAFETY
00-4 WA250-5L WA250PT-5L
124. 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 prevent the component from hitting any other part. Do not work with any part still raised by
the hoist or crane.
5. 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.
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 to the floor, wipe it up
immediately. Fuel or oil on the floor can cause you to slip, or can even start fires.
8. Never use flamable liquids to clean parts, always use approved non-flamable solvents to clean parts.
9. Be sure to assemble all parts in their original locations. Replace any damaged part 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, be sure that they are not twisted. Damaged tubbing is dangerous, be extremely
careful when installing tubes for high pressure circuits. Also make sure parts are correctly installed.
11. When assembling or installing parts, always use the specified tightening torques and sequences. When installing
protective parts such as guards, or parts that may vibrate or rotate at high speeds, be particularly careful to check ther
installation carefully.
12. When aligning two holes, never insert your fingers or hand. Use approperate tools to alighn parts.
13. When measuring hydraulic pressure, be sure the measuring tool is correctly assembled before taking any measurements.
14. Take care when removing or installing the tracks on track-type machines. When removing the track, the track separates
suddenly, never let anyone stand at either end of the track.
