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,
Qty
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 28).
— 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.
