Rotating/Replacing
Cutterhead Inserts
(G0889Z)
The spiral 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 25.

Items Needed
Phillips Screwdriver #2 ...................................... 1
Wrench or Socket 12, 13mm ............................. 1
Torque Wrench .................................................. 1
T-Handle Torx Wrench T-25 .............................. 1

To rotate or replace a spiral cutterhead insert:
1.
DISCONNECT MACHINE FROM POWER!
2.
Remove dust port, top cover, and belt cover.
3.
Put on heavy leather gloves to protect your
fingers and hands.
The carbide inserts are very sharp and
can quickly cut your hands. ALWAYS use
caution and heavy leather gloves when
handling these parts to reduce the risk of
personal injury.
Model G0889/G0889Z (Mfd. Since 12/18)
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 achieving
a smooth finish. Dirt or dust trapped between
insert and cutterhead will raise insert, and
make marks on your workpiece when 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 25).
— 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 the threads,
excess oil will attempt to squeeze out of the
threaded hole and raise insert during installa-
tion, bringing it out of height alignment.
