Replace if the leakage exceeds 1.0 litre/min
(0.22 gal/min) with the handle in the neutral
position or 2.0 litre/min (0.44 gal/min)
during operation.
Replace when the sliding contact faces are
worn more than 0.01 mm (0.0004 in) or
more than the non-sliding contact faces.
Replace if the
tip is worn
more than 1
mm (0.039 in).
Replace the parts if the wear in the pin and
joint lead to loose movement of more than
2 mm (0.079 in).
Investigate if abnormal noises, jerky
operation or drops in primary pressure are
experienced during operation. Replace the
valve if the problem cannot be solved.
Note
Condition:
Primary pressure 29 bar
(30 kgf/cm
2
426.5 lbf/in
2

Oil viscosity 23 cSt.
The conditions are approximately
the same as for the leakage
