20.1.7 Replacing jaws
To replace the jaws, you must open the lathe chuck with the chuck key. In the fully open
position, the jaws can then be removed one by one.
The following must be observed when
inserting the jaws:
 The threaded segments (2) of the jaws
are graduated as shown in the figure.
 In addition, they are numbered (1) from 1
to 3 to indicate the actual pitch in the
lathe chuck.
Therefore, make sure to mount the jaws in the correct order:
1. Arrange the jaws as shown in the figure above and insert them clockwise into the slots of
the lathe chuck in this order.
2. Hold the jaws and clamp them with the chuck key.
3. Close the chuck completely and check that the jaws meet in the middle.
If a jaw does not fit properly, open the lathe chuck, press firmly on the jaw and turn the chuck
key until the jaw is in the correct position. Check again that the jaws meet in the middle.
