Apply new piston detector (8) to the adapter
(7) and tighten gently.
Avoid uncontrolled tightening of
the piston detector.
:
This could cause damage.
Maintain tightening torque of
7
0.5
Nm
.
• Tighten the piston detector (
8
) with a
torque of
7
0.5
Nm
.
See Figures 1 and 7
• Depressurize the lubrication system and
metering device
• If possible, place a drip pan for the dis-
charging lubricant below the correspond-
