26 Assemble the complete base jaws (2) and the chuck piston (3).
Be sure to observe the installation position for the base jaws
and the chuck piston. Make sure no parts fall out when in-
stalling the base jaw units.
27 Connect the clamping system to the air supply and move the
jaws to the OPEN position.
28 Screw down the chuck piston (3) and cylinder piston (4).
Tighten the screw (14) with a torque wrench
29 Attach the covering strip (7).
30 Check for leaks (see Chapter 9.2).
31 Check to see that the clamping block is functioning properly.
This requires the changing jaws (as WTR or WTG accessories).

Leak test
The following is needed to check for leaks:
pressure gauge, shut-off valve and quick coupler.
Check for leaks in the clamping block in the CLOSED position.
• 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.
1 Connect the components to the open CLOSED connection in
the following order:
pressure gauge, shut-off valve, coupling, supply line.
2 Pressurize the clamping block.
3 Close the shut-off valve and remove the supply line.
4 Let the clamping block sit clamped for 24 hours.
5 After 24 hours, the clamping block is:
- sealed if the pressure gauge indicates a drop in pressure of
less than 0.5 bar
- leaking if the pressure gauge indicates a drop in pressure of
more than 0.5 bar.
If the clamping system is leaking, check the screws first (e.g., with
Metaflux leak detection spray). Seal any leaking screws.
Once the screws are sealed, check for leaks and replace if
necessary (see Chapter
Maintenance and care
( 9.1, Page
