1.3.2 Points to remember when handling hydraulic equipment
1. Be careful of the operating environment
Avoid adding hydraulic oil, replacing
fi
lters,
or repairing the machine in rain or high
winds, or places where there is a lot of
dust.
2. Disassembly and maintenance work in
the fi eld
If disassembly or maintenance work is
carried out on hydraulic equipment in the
field, there is danger of dust entering the
equipment. It is also difficult to check the
performance after repairs, so it is desir-
able to use unit exchange. Disassembly
and maintenance of hydraulic equipment
should be carried out in a specially pre-
pared dust-proof workshop, and the perfor-
mance should be checked with special test
equipment.
3. Sealing openings
After any piping or equipment is removed,
the openings should be sealed with caps,
tapes, or vinyl bags to prevent any dirt or
dust from entering. If the opening is left
open or is blocked with a rag, there is
danger of dirt entering or of the surround-
ing area being made dirty by leaking oil so
never do this. Do not simply drain oil out
onto the ground, but collect it and ask the
customer to dispose of it, or take it back
with you for disposal.

With the increase in pressure and precision
of hydraulic equipment, the most common
cause of failure is dirt (foreign material) in the
hydraulic circuit. When adding hydraulic oil, or
when disassembling or assembling hydraulic
equipment, it is necessary to be particularly
careful.
