Helical 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. 33. 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.
