3. Raise the knife bar.
4. DISCONNECT THE POWER AND LOCK IT OUT! (See Power Lockout procedure, page 5.)
5. Use the cutting stick puller to remove the cutting stick. Turn the cutting stick to a new
surface.
6. Clear the cutter table and extension tables. Place chipboard directly under the knife to
prevent nicking if the blade hits the table.
7. Check to make sure that all three (3) of the knife adjusting screws have been backed out, see
step 3 of Knife Removal section 10.1.1.1 on page 41.
8. Place the knife scabbard on the cutter table.
9. Remove the knife retainer screws holding the knife in the knife scabbard. Insert the knife
lifters into the knife bolt holes on the knife (use the lowest holes) corresponding to the slots in
the knife bar. Turn the threaded portion of knife lifters into the threaded holes in the knife
until they contact the scabbard, then back off 1-1/2 turns.
10. Grasp the knife lifters, lift the blade, and insert the blade into the knife bar slot. Slowly guide
the blade into the cutter right end first, then bring the left end in parallel to the knife bar.
Raise the knife into the knife bar slot as high as it will go. Tighten the lifters to hold the knife.
NOTE: If the blade will not go in, either the lifters are screwed into the blade too far or the blade is
not centered over the table, and the end of the blade is hitting the end stop in the knife bar.
