INSTALLING KNIVES
CAUTION: Use care when working with
or around sharp knives. Make sure
power to the machine has been
disconnected.
When installing new knives, remove only one
knife at a time. Clean the knife slot and install the
new knife. Adjust and lock new knife in cutterhead
assembly before proceeding to next knife.
1.
Disconnect machine from power source.
2. Remove the old knives by loosening gib
screws with an 8mm wrench, and allowing
the springs to push the knife upward.
Remove knife and gib. See Fig. 13.
3. Clean the gib and the knife slot. Sandwich
new knife and gib together and drop into
slot.
4. NOTE: To position the knife for rabbeting
cuts, a 1/32 inch shop scale should be
placed flat on the end of the cutterhead or
the rabbet slot, whichever extends the
farthest. Slide the knife out until it is flush
with the end of the shop scale. Set the knife
locking gib 1/32 inch in from the end of the
knife. See Fig. 14.
The height of the knife in the slot must now be set
properly, to minimize the hazard of kickback.
Proceed as follows:
5.
Rotate the cutterhead (using the pulley) until
the tip of the knife is at the top of the
cutterhead arc. Place the knife setting gauge
(Fig. 15) over the cutterhead so the tip of the
knife contacts the center of the gauge, and
all four "feet" of the gauge rest firmly upon
the cutterhead, as the knife is pushed down
into its slot. The gauge will set the knives at
approximately .070" above the cutterhead.
Knife height should not vary more than .002-
.003" across the length of the cutterhead.
6.
Tightening the gib screws should be done in
increments, to prevent any distortion to the
cutterhead or buckling of knives. While
holding the gauge down on one knife, snug
down the five gib screws, beginning with the
center screw and working your way to the
ends. Do not fully tighten yet.
