Immediately after using the lift truck, the oil is at high temperature. Do
not drain the oil or replace the filter when the oil is hot. Hot oil may spurt
out and cause burns.
When carrying out inspection and maintenance, wait for the oil
temperature to go down, and carry out the operation in the order given
in this manual.
Do not forget that the work equipment circuits are always under
pressure. Do not add oil, drain oil or carry out maintenance or inspection
before completely releasing the internal pressure.
If oil is leaking under high pressure from holes, it is dangerous if the jet
of high-pressure oil hits your skin or eyes. Always wear safety glasses
and thick gloves, and use a piece of cardboard or a sheet of plywood to
check for oil leakage.
Release the internal pressure before checking the accumulator piping.
If you are hit by a jet of high-pressure oil, consult a doctor immediately.
NEVER put your hands or feet into the mast structure. There is danger that
you will get caught in moving parts and be seriously injured.
Do not use the mast, load backrest or dashboard as a ladder. If you slip, there
is danger that you will fall.
