KNIFE SETUP
Flattened view of knife drum with
standard setup with 20 knives.
This setup gives a balanced
rotation of the knife drum. The
scrapers are placed on both
sides of the segment with fewer
knives, as shown on the first row
on figure 12.
REPLACING KNIVES
The knives are secured with a bolt and a nut that
goes into a keyhole slot in the drum. To replace the
knife, loosen the bolt a little bit, the knife is then
loose and can be pushed up and taken out the wide
part of the keyhole. The nut is held by the geometric
design of the keyhole. Make sure not to loosen too
much, the nut will then fall off and into the drum.
New knives are assembled by placing bolt and nut in
the wide end of the keyhole, push down and secure
the knife by tightening the bolt. Make sure the pin
on the back of the knife is placed in the slot on the
drum.
