Maintenance intervals
Lubrication of the grease areas:
Lubrication interval Strain
every 25 hours normal / coolant utilization
every 8 hours high / coolant utilization
after 1200 hours or
as needed
Total cleaning with disassembly of the
chuck, depending on type and degree of
contamination
Technical condition
With the smallest possible actuating pressure (hydraulic cylinder),
the base jaws should move evenly. This method only provides a
limited indication and is not a substitute for measuring the
clamping force.
If the clamping force has dropped too far or if the base jaws and
clamping piston no longer move properly, the chuck has to be dis-
assembled, cleaned and relubricated.
Disassembly and assembly of the chuck
The item numbers specified for the corresponding individual
components relate to chapter drawings.

• Unscrew the screws (item 18) from the mount (item 7) for sizes
400 and 500.
• Undo the screws (item 20) several thread turns and hammer
gently on the screw heads using a rubber mallet. The mount
(item 7) is thus released from the centering for the chuck body
(item 1). Unscrew the screws (item 20) and remove the mount
(mark position of the chuck cover to chuck body).
• Remove the safety bolts (item 9) with compression springs
(item 29) and balls (item 23) from the chuck body.
• Remove the jaw-change bolts (item 8) with balls (item 23) and
unscrew the chuck piston (item 3).
