• The coolant and oil in the circuits are hot when the engine
is shut down. Be careful not to get scalded. Wait for the oil
and coolant to cool before performing any work on the oil
or coolant circuits.
• Before starting work, shut down the engine. When working
on or around a rotating part, in particular, shut down the
engine. When checking the machine without shutting down
the engine (measuring oil pressure, revolving speed, tem-
perature, etc.), take extreme care not to get caught in ro-
tating parts or moving parts.
• When raising a component heavier than 25 kg), use a hoist
or crane. Before starting work, check that the slings (wire
ropes, webbing slings, chains, and hooks) are free from
damage. Always use slings which have ample capacity
and install them to proper places. Operate the hoist or
crane slowly to prevent the component from hitting any
other part. Do not work with any part still raised by the
hoist or crane.
• When removing a part which is under internal pressure or
under reaction force of a spring, always leave 2 bolts in di-
agonal positions. Loosen those 2 bolts gradually and alter-
nately to release the pressure, and then remove the part.
• When removing components, do not break or damage the
electrical wiring. Damaged wiring may cause a fire.
• When removing piping, do not spill the fuel or oil. If any
fuel or oil drips onto the floor, wipe it off immediately. Fuel
or oil on the floor can cause you to slip and can even cause fires.
• Do not use gasoline to wash parts as a general rule. Do not use gasoline to clean electrical parts, in partic-
ular.
• Be sure to assemble all parts again in their original places. Replace any damaged parts and parts which
must not be reused with new parts. When installing hoses and wiring harnesses, be sure that they will not
be damaged by contact with other parts when the machine is operated.
• When installing high pressure hoses and tubes, make sure that they are not twisted. Damaged hoses and
tubes are dangerous, so be extremely careful when installing hoses and tubes for high pressure circuits. In
addition, check that high pressure hoses and tubes are correctly installed.
