Unplug the machine from the power source, and place the machine upside down.
Unlock
the
lever
(

, Fig. 2), and then rotate the sleeve (

) to lower it as far as possible
and access the milling head. Use the special wrench

to loosen the roller, and then
use the screwdriver

to unscrew the inserts. Next, clean the sockets, push the inserts
into the sockets, and then retighten the inserts and roller. The entire bottom of the
insert must be in full contact with the socket (

To change the cutting edge, unscrew the insert, rotate it by 90°, push into the
socket, and tighten. If all cutting edges are worn, replace the inserts with new ones.
