The valve system (13) must be removed before proceeding with

4 Check all the O-rings in the valve system for wear and replace
them if necessary.
5 Unscrew the hexagon socket screws (23) from the chuck
mount (7), then screw 3 of them into the threaded extraction
holes provided and use them to extract the mount. Remove
the mount and O-rings (39,44).
6 Undo the hexagon sockets screws (25) that connect the piston
cover (6) to the piston (3).
7 Screw three hexagon socket screws into the threaded holes on
the piston cover (6) and extract the piston cover (6) from the
piston (3).
