4.10.2 Adjusting the Camlock bolts to the workpiece holder
Insert all of the bolts in the screwed flange of the chuck, until the reference mark, the circular
reference line (F) is in line with the wall of the chuck flange surface and the semicircular
grooves are in line with the holes of the safety screw (E).
Fit the safety screw (E) into each bolt and tighten.
Make sure that the two contact sides (plate and shaft) are free from impurities.
Now the chuck can be mounted.
Before coupling the chuck to the shaft nose, check that the clamp bolts are in an unlocked posi-
tion.
Fasten the workpiece holder by turning the clamping bolts clockwise.
INFORMATION
The reference mark (F) on each Cam-lock bolt serves as an orientation for the correct
adjustment.

Lathe chuck
The workpieces must be clamped firmly and securely onto the lathe before they are machined.
The clamping force should be strong enough to ensure that the workpiece is moved correctly,
but not so tight that it is damaged or deformed.
Spare chucks must be designed for the maximum rotational speed of the machine, the permis-
siblechuck speed must be marked on the chuck. The minimum distance to the machine bed
must not be less than 25 mm.
WARNING!
Do not clamp any workpieces that exceed the permitted chucking capacity of the lathe
chuck. The clamping force of the chuck is too low if its capacity is being exceeded. The
clamping jaws may loosen. Only use lathe chucks designed for the speed of the
machine. Do not use lathe chucks with an external diameter that is too large.
CAUTION!
When clamping workpieces or assembling heavy weight lathe chucks and rests,
reasonable stress loads on the operator or assembler may be exceeded.
