Testing the leakage and tightness of the hydraulic system
The following is needed to check for leaks:
hydraulic unit or manually actuated hydraulic pump, pressure
gauge, shut-off valve and quick couplers.
• Check for leaks in the clamping system in the OPEN and CLOSED
positions.
Connect the components for the leakage and tightness test on the
clamping system in the following order:
1 Adjust the hydraulic unit with pressure gauge and shut-off
valve to minimum pressure.
2 Connect the hydraulic screw fittings to the
frontal
OPEN and
CLOSED connections.
3 Link the supply line and hydraulic coupling to the hydraulic
screw fittings.
The leakage and tightness test is to be performed in the following
order:
1 Actuate the clamping force block with reduced hydraulic
pressure.
Check the clamping force block for free movement by opening
and closing the jaws several times.
2 Check the clamping force block with the maximum permissible
hydraulic pressure.
3 Inspect the outside of the TANDEM clamping force block for
visible signs of damage and oil leakage.
Measures in the event of a leaking hydraulic system
If the clamping system is leaking, check the fittings first.
Seal any leaking fittings. Once the fittings are sealed, check the
seals in the clamping force block for leaks and replace if necessary.
