-4- T24631 6" spiral Cutterhead
When correctly set, the carbide insert will just
touch the straightedge when the insert is at
its highest point of rotation (figure 9).
—if your outfeed table is correctly set, no
adjustments are necessary.
—if the insert lifts the straightedge off the
table or the table is below the straight-
edge, adjust the outfeed table height with
the handwheel until the straightedge just
touches an insert at its highest point of
rotation.
20. Lock the outfeed table, then re-install the
fence.
21. install the cutterhead guard back over the
cutterhead, making sure that the spring ten-
sion in the guard is properly set so the guard
springs back over the cutterhead when it is
pulled back and released.
22. re-adjust the infeed table.
in addition, each insert has a reference dot on
one corner. as the insert is rotated, the reference
dot location can be used as an indicator of which
edges are used and which are new. The insert
must be replaced when all four edges are dull.
installing or adjusting a carbide cutter:
1. disConneCT JoinTer FroM PoWer!
2. remove any sawdust from the head of the
carbide insert Torx screw.
3. remove the Torx screw and carbide insert.
4. Clean all dust and dirt off the insert and the
cutterhead pocket from which the insert was
removed, and replace the insert so a fresh,
sharp edge is facing outward.
note: Proper cleaning is critical to achieving
a smooth finish. Dirt or dust trapped between
the insert and cutterhead will slightly raise the
insert, and make noticeable marks on your
workpieces the next time you cut.
5. Lubricate the Torx screw threads with a
light machine oil, wipe the excess oil off the
threads, and torque the Torx screw to 48-50
inCh pounds.
note: Excess oil may squeeze between the
insert and cutterhead or in the screw hole,
thereby lifting the insert or screw slightly and
affecting workpiece finishes.

The cutterhead is equipped with 40 indexable car-
bide inserts. each inser t can be rotated to reveal
any one of its four cutting edges. Therefore, if one
cutting edge becomes dull or damaged, simply
rotate it clockwise 90˚ to reveal a fresh c utting
edge (figure 10).

19. Place a straightedge on the outfeed table
so it extends over the cutterhead, and rotate
the cutterhead pulley until one of the carbide
inserts is at top-dead-center (TdC), as shown
in figures 8 & 9.
