SAFETY SAFETY NOTICE PRECAUTIONS DURING WORK 20. 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 in- stalled. 11. When removing the oil filter 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. 21. When assembling or installing parts, always use the specified tightening torques.
When in- stalling protective parts such as guards. or parts which vibrate violently or rotate at high speed, be particulary careful to check that they are installed correctly. 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 carrying out any work on the oil or water circuits. 22. When aligning two holes, never insert your fin- gers or hand. Be careful not to get your fingers caught in a hole. 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 he correct places. Use a hoist of 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. 23. When messuring hydraulic pressure, check that the messuring tool is correctly assembled for 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. 15.
When removing covers which are under inter- nal 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 oil or fuel drops 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, only use the minimum of gasoline when washing electrical parts. 19.
Be sure to assemble all parts again in their original places. Replace any damaged parts with new parts. When installing hoses and wires, be sure that the will not be damaged by contact with oter parts when the machine is being operated. 00-4
