ShearTec II CUTTERHEAD
Knife inserts are dangerously
sharp. Use extreme caution when inspecting,
removing, or replacing knife inserts.
The knife inserts on the 25” Planer 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. 9. 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.
Warning: Disconnect machine from power source.
