Disassembly and assembly
The item numbers specified for the corresponding individual
components relate to chapter drawings.
Disassembly and cleaning
1 Unscrew both the pneumatic quick coupling pieces from the
distributor ring (item 8), and detach the distributor ring (item
8) from the spindle nose together with the bracket. Loosen
the chuck mounting screws (item 24) and lift the chuck from
the spindle nose with a crane using the supplied eye bolt
(thread on the chuck body circumference).
2 Remove both profile ring seals (item 47) from the distributor
ring (item 8) and check for wear. Before inserting the profile
ring seals (item 47) in the slots in the distributor ring, it is
recommended that you rub them with grease by hand so that
they remain elastic. There must be no visible grease residue.
When the profile ring seals (item 47) are reinserted, ensure
that air passage openings do not align with the pneumatic
connections of the distributor ring.
WARNING
Pressure in the chuck! Risk of injury due to ejected parts.
It is absolutely necessary to carefully remove the valve system
(item 13) before any further disassembly!
