Next, attach the knife assembly. Align the blades to
the already drilled holes and tighten the holder socket
screw.
Reattach the pressure foot assembly using the two
knurled screws.
For best results, lay a sheet of chipboard underneath
your work and set the depth-of-cut so it just makes it
through the chipboard. The blades should not cut into
the wood block when slotting or slitting.
Slitting
For slitting work, remove the knife thrust block, take
out the left hand knife and set it aside.
Remove the right hand knife and position it in the left
hand knife slot.
Place the knife holder in the right hand knife slot and
replace the thrust block and screw. Replace the knife
holder in the mounting bracket and turn the holder in
the bracket to cut a straight slit. Make your first slit
farthest from the side guide*, then slit the other side of
F.330-J/APR 97
the hole and proceed to the next slot position.
For narrow slots, position the side guide stops for the
first cut farthest from the side gage*. Leaving the side
gage at the same position, lift the side guide face and
turn it around.
Jog the stock square against the back and side gages
and make the second cut. Your slot is now complete.
Remember to return the side guide face to the standard
position before making the next slot.
*Always make the first cut farthest from the side gage.
This prevents draw on the paper that would give
irregular cuts.
NOTE: Maximum slitting and slotting capacity is
1/2" (13 mm). Be sure to check the stroke adjustment
to prevent the knives from cutting too deep into the
cutting block.
