6. Taking care not to strip Torx screw, care-
fully remove Torx screw and insert, then thor-
oughly clean away all dust and debris from
insert and insert pocket in cutterhead.
IMPORTANT: This step is critical for achiev-
ing a smooth finish with cutting operations.
Dirt or dust trapped under insert during instal-
lation will slightly raise insert in cutterhead,
which will leave marks on final workpiece.
Tip: Use low-pressure compressed air or
vacuum nozzle to clean cutterhead pocket.
7. Re-install insert with a sharp cutting edge
facing outward. Make sure insert is properly
seated in cutterhead pocket before securing.
— If all four insert cutting edges have been
used, replace insert with a new one.
Always position reference dot in same
position when installing a new insert to aid
in rotational sequencing.
8. Install Torx screws and torque screws to
48–50 inch/pounds.
Tip: To help avoid leaving inserts loose or
unrotated, use a paint pen to mark completed
inserts.
9. Close chain drive access door and and
replace upper cutterhead dust hood and belt
cover.
