scabbard's knife retaining screws.
5. Grasp the knife lifters firmly and, at the same time, turn them counterclockwise to release the
knife from the knife bar. Lower the entire assembly down, then move the knife to the left slightly
then bring the knife out of the cutter, right end first. Put the blade in the scabbard immediately,
remove the knife lifter assembly, and secure the knife with the knife retainer screws.

dismemberment could result from careless handling procedures.
1. Make sure the knife and clamp are in the "up" position. Turn the main power switch off and
disconnect the machine power cord to prevent accidental power-up while servicing the cutter.
2. Pull out the cut stick and turn it to a new surface or replace with a new one.
3. Remove the retainer screws from the new blade and screw the knife lifters into the new
blade. Screw the lifters about half way into the knife.
4. Insert the knife assembly into position under the knife bar, left end first. Raise the knife into
the knife bar slot as high as it will go. Check both view holes to make sure knife is all the way
up (Figure 15). Then tighten the lifters.
NOTE: If the blade will not go in, make sure the lifters are not screwed into the blade too far.
