The cutterhead is equipped with 36 indexable car-
bide inserts. Each insert 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 (see
Figure 43).
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. When the
reference dot revolves back around to its starting
position, the insert should be replaced.
To rotate or change a carbide insert:
1.
DISCONNECT MACHINE FROM POWER!
2.
Remove any sawdust from head of carbide
insert Torx screw.
3.
Remove Torx screw and carbide insert.
4.
Clean all dust and dirt off insert and
cutterhead pocket from which insert was
removed, and replace 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 Torx screw threads with a light
machine oil, wipe excess oil off threads, and
torque Torx screw to 48–50 in.-lbs.
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.
8.
Place straightedge in one of the positions
shown in Figure 38, and adjust eccentric
bushings under infeed table so straightedge
lies flat against both tables. Repeat this step
with each remaining straightedge position as
many times as necessary until infeed table is
parallel with outfeed table.
9.
Tighten set screws and re-install covers on
infeed table.
10.
Set outfeed table height (refer to
Setting
Outfeed Table on Page 41).
11.
Re-install cutterhead guard and fence.
