Rotating/Replacing
Cutterhead Inserts
The helical cutterhead is equipped with indexable
carbide inserts that can be rotated to reveal any
one of their four cutting edges. If one edge of the
insert becomes dull or damaged, simply rotate it
90° to reveal a fresh cutting edge, as shown in
Figure 31.

To rotate/replace cutterhead insert:
1.
DISCONNECT MACHINE FROM POWER!
2.
Remove dust port housing if installed on
top of outfeed table (see Figure 32), rotate
cutterhead guard over infeed table, and
secure with lock-out.

3.
Put on heavy leather gloves to protect your
fingers and hands.
Carbide inserts are very sharp and can
quickly cut hands. ALWAYS use caution and
heavy leather gloves when handling these
parts to reduce risk of personal injury.
4.
Remove any sawdust or debris from head of
insert, Torx screw, and surrounding area.
5.
Remove Torx screw and insert, then clean all
dust and debris from both parts and pocket
they were removed from.
Note: Proper cleaning of insert, Torx screw,
and cutterhead pocket is critical to achiev-
ing a smooth finish. Dirt or dust trapped
between insert and cutterhead will raise
insert, and make marks on your workpiece
when jointing/planing.
Tip: Use low-pressure compressed air or
a vacuum nozzle to clean out cutterhead
pocket.
6.
Rotate insert 90° and install so that a fresh
cutting edge faces outward (see Figure 31).
— When all four insert cutting edges have
been used, replace insert with a new one.
Always position insert reference dot in
same position when installing a new insert
to aid in rotational sequencing.
7.
Lubricate Torx screw threads with a very
small amount of light machine oil, wipe
excess off, and torque screw to 50–55 inch/
pounds.
Note: If too much oil is applied to threads,
excess oil will attempt to squeeze out of
threaded hole and raise insert during installa-
tion, bringing it out of height alignment.
8.
When finished, re-install dust port housing
and release lock-out so guard will swing back
over cutterhead.
