6).
3 Remove the cylindrical screw (item 14) from the chuck piston.
4 Close the clamping block so that the jaws are in the CLOSED
position.

Remove the pressure line. There must be no more residual
energy in the clamping block.
6 Pull the plugs (item 8) out of the housing (item 1).
7 Loosen the screws (items 9, 19) and remove the clamping block
from the machine table. Residual air may escape at this point.
