base jaws (2) can be pulled out of the base jaw guides from
the inside, through the piston bore hole in the chuck body.

guides in the chuck body, the base jaws and the piston on the
wedge hooks are greased with LINOMAX special grease paste.
SCHUNK offers complete sealing kits for the O-rings.
Assembly
The chuck is assembled in the same way, but in reverse order.
Observe the following points when doing this:
1 The base jaws (2), the base jaw guides in the chuck body (1)
and the hardened reversible jaws are all numbered 1, 2, and 3.
Insert the base jaws (2) in the corresponding guides to achieve
the same run-out accuracy.
