10.4.10Knife replacement
Replace knife lock-nuts and bolts when they
have been removed 5 times.
Replace immediately all worn or distorted
knives. Never straighten a bent knife.
Always replace both knives per disc.
- Clean the nut case.
- Place a wooden wedge between two discs to stop
them from rotating.
- Loosen nut using box spanner supplied with the
machine.
- Remove bolt through opening located at the front of
the disc guard.
Knives can be turned over on the same disc to use
the other cutting edge or replaced. On each knife, an
arrow indicates the disc's direction of rotation.
- Make sure that the securing nut and bolt are in
good condition and if necessary, replace them.
- Torque knife locknut to 12 daN m (89 lbf ft).
Dull knives require more horse power and have a
negative effect on the cut quality.
