SECTION 7: SERVICE
In addition, each cutter has a reference dot on
one corner. As the cutter is rotated, the reference
dot location can be used as an indicator of which
edges are used and which are new. When the
reference dot revolves back around to its starting
position, the cutter should be replaced.
Rotating/Changing
Carbide Cutters
To rotate or change a carbide cutter:
1. DISCONNECT THE PLANER FROM THE
POWER SOURCE!
2. Remove any sawdust from the head of the
carbide cutter Torx screw.
3. Remove the Torx screw and carbide cutter.
4. Clean all dust and dirt off the cutter and the
cutterhead pocket from which the cutter was
removed, and replace the cutter so a fresh,
sharp edge is facing outward.
Note: Proper cleaning is critical to achieving
a smooth finish. Dirt or dust trapped between
the cutter and cutterhead will slightly raise the
cutter, and make a noticeable marks on your
workpieces the next time you plane.
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
cutter and cutterhead, thereby lifting the cut-
ter slightly and affecting workpiece finishes.

The cutterhead is equipped with 72 indexable car-
bide cutters. Each cutter can be rotated to reveal
any one of its four cutting edges. Therefore, if one
cutting edge becomes dull or damaged, simply
rotate it 90˚ to reveal a fresh cutting edge, as
shown in
Figure 23.
