SAFETY NOTICE FOR OPERATION
•
Release the remaining pressure from the circuit before starting the work of disconnecting and removing of
oil, fuel, water, or air from the circuit. When removing the cap of oil filter, drain plug, or oil pressure plug, it
should be done slowly otherwise the oil spills.
•
When removing or installing the checking plug or the piping in the fuel circuit, wait 30 seconds or longer
after the engine is shut down and start the work after the remaining pressure is released from the fuel cir-
cuit.
•
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 heavy 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.
