Slitting - Challenge JO Instructions And Parts Manual

Reattach the pressure foot assembly using the two snap rings.
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.

10.3.2 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 the hole and proceed to the next slot
position.
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.
*Always make the first cut farthest from the side gage. This prevents draw on the paper that would
give irregular cuts.
