14. Restore power to machine and turn power on.
15. Press CLEAR. This will raise the knife and clamp to the up position.
16. Turn the power off and lockout power to machine.
17. Tighten all knife bolts securely.
18. Restore power to machine and turn power on. Make a test cut through a full lift of paper and
make minor adjustments if necessary by repeating steps 9 through 17. NOTE: If the knife
ends cut but the middle doesn’t, you could have dips or uneven spots in the knife and/or
cutting stick. These can be eliminated by placing 1/2” strips of paper in the table slot beneath
the cutting stick to shim it.
19. Send the dull knife to a knife grinder. Do not attempt to sharpen your own knives! See the
Knife Care Tips Section below to determine the knife bevel angle.
7.3 Knife Care Tips
! KNIFE SAFETY ! Knives are DANGEROUS!!! They are heavy and very
sharp, even after use. Keep the edge away from your body and keep the area clear of others when
handling knives. Never touch the cutting edge! To prevent personal injury and damage to the knife,
always keep knives in their holders with screws tightened. You are aware of the dangers, but others
may not be. Never attempt to hone, polish, or service the knife in any way. Failure to follow safety
procedures may result in severe lacerations or dismemberment.
7.3.1 Knife Blade Life
Knife blade life, or the time between sharpenings, can be affected by many factors. One important
factor is the type of paper being cut. Abrasive paper, such as recycled paper, soft paper such as
newsprint paper, and bound books can all significantly shorten knife blade life. Also, if the knife depth
is set too deep, the knife will cut too deep into the cutting stick and can dull the knife blade.
A knife can last between 2,000 and 5,000 cuts before it needs to be sharpened. Cutting soft paper
(such as newsprint paper) or paper with high post-consumer recycled content can cause the knife to
need sharpening after only 2,000 to 3,000 cuts. Cutting pure paper, such as bond paper with no
recycled content, or hard paper can allow the knife to be used for as many as 5,000 cuts before it
needs to be sharpened. In all cases, the operator should continually check the quality of the cut to
determine when the knife blade needs to be sharpened. Some characteristics that indicate a blade
needs sharpening are:
