5. Use a straight edge and feeler gauge to
check that the cutter head is parallel with
the outfeed table (shim if necessary)
(Fig.14) Place the straightedge in position,
on one side of the outfeed table and raise
or lower outfeed table until the
cutterhead body (not the insert) just
touches straightedge. (Fig.14)
Move the straightedge to the other side
to determine if one end of cutterhead
body is higher/lower than the other.
(Place feeler gauge between cutterhead
body and straightedge to determine the
height dierence.) Place shim under the
bearing blocks until parallel.

6. Remove the wooden blocks and bolt the
machine back onto stand.

7. Re-install the key onto the keyway, then
press pulley onto new cutterhead shaft

8. Ret the belt, belt cover, rear cover
and dust port (Ensure the Belt is in good
alignment).

CHANGING INSERTS

The cutterhead is equipped with indexable
inserts.
28 Inserts SHC6-28 (W761)

40 Inserts SHC8-40 (W763)

Each insert can be rotated to reveal one of
its four cutting edges. If one cutting edge
becomes dull or damaged, then rotate it
clockwise 90˚ to reveal a fresh cutting edge.
Each corner of the insert has a reference
mark. As the insert is rotated, the reference
mark 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
(Fig.16

INSTALLING OR ADJUSTING A HSS INSERT

1. DISCONNECT MACHINE FROM POWER!

2. Remove any sawdust from the insert and
the insert Torx screw.

3. Remove Torx screw and HSS insert.

4. Clean all dust and dirt o the insert and
cutterhead pocket and replace the insert
so a fresh, sharp edge is facing outward.
Note: Proper cleaning is critical to achieving
a smooth nish. Dirt or dust trapped
between the insert and cutterhead will 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 o threads,
and tighten the Torx screw.
Note: Excess oil may squeeze between insert
and cutterhead or in screw hole, thereby
lifting insert or screw slightly and aecting
workpiece nishes.
