SHEAR-TEC II Cutterhead
Knife inserts are dangerously
sharp. Use extreme caution when inspecting,
removing, or replacing knife inserts.
The knife inserts on the Jointer are four-sided.
When dull, simply remove each insert, rotate it 90°
for a fresh edge, and re-install it. No further
adjustment is necessary. Use the two provided
torx
wrench
to remove the knife insert screw. Use one
of the torx wrenches to help hold the cutterhead in
position, and the other to remove the screw. See
Fig. A. It is advisable to rotate all inserts at the
same time to maintain consistent cutting. However,
if one or more knife inserts develops a nick, rotate
only those inserts that are affected.
Each knife insert has an etched reference mark so
you can keep track of the rotations.
IMPORTANT: When removing or rotating inserts,
clean saw dust from the screw, the insert, and the
cutterhead platform. Dust accumulation between
these elements can prevent the insert from seating
properly, and may affect the quality of the cut.
Before installing each screw, lightly coat the screw
threads with machine oil and wipe off any excess.
Securely tighten each screw which holds the knife
inserts before operating the jointer!
Make sure all knife insert screws are tightened
securely. Loose inserts can be propelled at high
speed from a rotating cutterhead, causing injury.
