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 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, Damaged wiring may cause
electrical fires.
17. 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.
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 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.
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 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 partic-
ularly careful to check that they are installed
correctly.
22. When aligning two holes, never insert your fingers 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.
