Replacing The Cutting Inserts - Promotech BM-16 Operator's Manual

3.6. Replacing the cutting inserts

Unplug the machine from the power source, and place the machine upside down.
Next, loosen the clamping screw (1, Fig. 8) to access the milling head, and lower the
sleeve as far as possible by rotating it to the right (2). Then, use the screwdriver supplied
with the milling head to unscrew the screw (3), and remove the cutting insert (4).
Clean the socket, and then rotate the insert and install again or replace with a new
one if all possible to use edges are worn. Next, push and tighten the insert. The entire
bottom of the insert must be in full contact with the surface of the socket (5).
Before replacing the cutting inserts of the radius milling head, press and hold the
spindle lock button 6 and loosen the guiding roller with the 5 mm hex wrench (7).
