Flushing operations
After disassembling the equipment or when
q
changing the hydraulic oil with new one, flush
the system to remove the contaminant and
sludge left in the hydraulic circuit as well as the
oil which includes them. Normally, flushing is
performed twice. Primary flushing is performed
by use of the flushing oil and the secondary
flushing is performed by use of the specified
hydraulic oil.
Cleaning operations
q After repairing the hydraulic equipment (pump,
control valve, etc.) or when the machine is in
operation, perform oil cleaning to remove the
sludge or contaminant in the hydraulic oil cir-
cuit. The oil cleaning equipment can remove
the ultra fine (approximately 3 μm) particles
that the filter built in the hydraulic equipment
can not remove. So, it is an extremely effective
device.
