4.4.3 Knife Spacers
CAUTION
The knives must be adjusted after every knife
change. Improper knife adjustment may cause
damage to the machine.
CAUTION
All three knives are a set. They must be sharp-
ened as a set. Damage or poor performance
may result if knives are not from the same set.
WARNING
Changing knives can be very dangerous un-
less safety precautions are observed and ex-
treme care is taken when handling knives.
Keep handling of unprotected knives to an
absolute minimum. Have the scabbard
nearby and insert knife immediately. Warn
people of any unprotected knife.
WARNING
Knife changing is a ONE PERSON
OPERATION! More than one person chang-
ing a knife creates safety hazards.
WARNING
Even used knives are extremely sharp! Use
extreme care when handling new/re-ground
knives and used knives.
Each time a set of knives are sharpened, a small
amount of material is removed. Once the knife
height (Figure 4-16) gets below approximately 2-
5/8” (67mm), the knives will not cut all the way
through books, even when the knife depth is ad-
justed as far down as it will go. When this hap-
pens, knife spacers may be placed on top of
each knife as shown in Figure 4-16 prior to in-
stalling the knives. The spacers are located in-
side the lower rear left door.
WARNING
When knife spacers are used, the knife
edges should never be below the surface of
the clamps once installed. If this happens,
the knives are too tall and the spacers
should be removed. Failure to do so creates
safety hazards, and damage to the machine
could result.
