Cutterhead Maintenance
Rotate / Replace Cutter Inserts
CAUTION
Cutter inserts on the cutterhead are extremely sharp. Protect your hands with thick
leather gloves to avoid injuries.
1. Disconnect jointer from power source!!
2. Put on leather gloves.
3. Remove cutterhead guard.
4. Move fence assembly all the way back and
above the table to expose the cutterhead.
5. Remove dusts and resin accumulations on
cutterhead and areas nearby.
6. Rotate cutter inserts 90° clockwise when
they get dulled or nicked. Use a permanent
marker to mark the new edge to be used.
7. To rotate/replace a cutter insert, remove
the torx screw with a T-25 torx bit. Turn
COUNTERCLOCKWISE to loosen the screw.
8. With the cutter insert removed from its
platform, thoroughly clean the cutter insert
platform with a vacuum or compressed air.
IMPORTANT: Obstacles between the insert
and cutterhead platform will create uneven
pressure against the insert. This will lower
cut quality and may cause the insert to crack.
9. Reinstall the cutter insert with the marked
cutting edge facing out.
10. Inspect the torx screw. Replace any
damaged screws. Lubricate screw thread
with a thin coat of light weight machine oil.
IMPORTANT: Do not use excessive amount
of lubrication, or the torx screw and the
cutter insert will not sit properly.
11. Using a torque wrench, re-tighten the torx
screw with 52-60 lbs.-inch of torque.
IMPORTANT: Do not overtighten the screw
or the inserts may break. Do not use power
tools to tighten the torx screws as it can strip
the screws.
12. Reinstall cutterhead guard and remove all
tools from table when servicing is done.
