Flushing operations
After disassembling and assembling the equipment, or changing
the oil, use flushing oil to remove the contaminants, sludge, and
old oil from the hydraulic circuit. Normally, flushing is carried out
twice: primary flushing is carried out with flushing oil, and
secondary flushing is carried out with the specified hydraulic oil.

Cleaning operations
After repairing the hydraulic equipment (pump, control valve, etc.)
or when running the machine, carry out oil cleaning to remove the
sludge or contaminants in the hydraulic oil circuit. The oil cleaning
equipment is used to remove the ultra fine (about 3 µ) particles that
the filter, built in the hydraulic equipment, cannot remove; it is an
extremely effective device.
