Rotate / Replace Cutter Inserts
CAUTION
Cutter inserts are extremely sharp. Wear thick leather gloves to avoid hand injuries.
1. Disconnect the jointer from the power
source!!
2. Put on leather gloves.
3. Remove cutterhead guard.
4. Move the fence all the way back and raise it
above the table to expose the cutterhead.
5. Remove dust and resin accumulations on
cutterhead and areas nearby.
6. Inspect the cutter inserts. Rotate the 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 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 lightweight machine oil.
IMPORTANT: Do not use an 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 lb-inch of torque.
IMPORTANT: Do not overtighten the screw
or the inserts may break. Do not use power
tools to tighten the Torx screws. Excessive
torque can strip the screws or damage the
cutter inserts.
12. Reinstall the cutterhead guard and remove
all tools from the table when servicing is
done.
