Cutterhead Removal

The entire cutterhead assembly may be removed
for cleaning or for bearing and blade replacement.
Some woodworkers keep a spare cutterhead with
replacement blades should the original cutterhead
have to be repaired.

Blades in the cutterhead are

sharp! Use extreme caution

when handling the removal of the cutterhead.
Failure to comply may cause serious injury!

studs, and housing) from the base casting:
