When making bevels of low width, the cutting inserts wear only on one, internal
corner. Then, the good action is to change the inserts between the rings of the milling
head (Fig. 14), which will extend the life of the inserts.

3.6. Replacing the milling head
Remove the milling head cover as shown in Fig. 12. Next, lock the rotation of the
spindle with the 32 mm flat wrench (Fig. 15), use the 8 mm hex wrench to unscrew
the screw, and remove the milling head. The 32 mm flat wrench is not included in
standard equipment.
