5.2 Changing the replaceable cut-
ting insert
CAUTION – Risk of injury from sharp
edges on the replaceable cutting
insert!
If the snap ring does not break apart despite
correct positioning of the CRI in the dismantling
tool, the cutting edge of the replaceable cutting
insert is dull. The replaceable cutting insert on
the spindle has two cutting edges. As soon as
one cutting edge is dull, the second cutting edge
can be used. This requires rotating the replace-
able cutting insert 180°.
