CAUTION: 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
other people 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 tight-
ened. Others entering the area may not be
aware of the dangers. Never attempt to
hone, polish, or service the knife in any way.
Failure to follow safety procedures may re-
sult in severe lacerations or dismemberment.
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 signifi-
cantly shorten knife blade life. Cutting pure
paper, such as bond paper with no recyled content
will cause less wear on the cutting blade. In all
cases the operator should continually check the
quality of the cut to determine when the knife
needs to be sharpened. Some characteristics that
indicate a blade needs sharpening are:
The knife hesitates or stalls while making a
cut.
The top sheets are not all cut to the same
length (usually the top few sheets are longer
than the rest of the sheets - this is sometimes
called "draw")
Cut marks appear on the cut face of the pa-
per.
The knife and/or drive makes a "rough" sound
as the knife passes through the paper.
Nicks are visible on the cutting edge of up-
per or lower knife.
Store knives in a dry environment to prevent corro-
sion.
Never attempt to service a knife in any way with-
out proprer training. It is recommended to main-
tain a spare set of knives as a back up.
