Replacing the clamping jaws on the lathe chuck

The clamping jaws and the three-jaw chuck
are provided with numbers. Check before
the change, if the numbers are readable
and, if necessary, mark the jaws and their
primary position. Insert the clamping jaws at
the correct position and in the right order into
the three-jaw chuck.

After the replacement, bring the jaws com-
pletely together in order to see if they are
inserted correctly.
