SHEAR BAR ADJUSTMENT - FIGURE 197
After knives have been ground and when the shear bar
is readjusted, only the screw (item 3) is used. As the
rounded tip screws (item 2) are resting on the oblique
shape of the shear bar, it moves slantwise and towards
the cutter head knives while remaining in a parallel pos-
ition (see arrow).
The shear bar (item 1) cuts as much material as all the
knives together. This bar has two tungsten covered cut-
ting edges (item 4). If and when one of these edges
grows blunt, turn the bar over and use the new cutting
edge.
DAILY ADJUSTMENT - FIGURE 196
(AFTER KNIVES HAVE BEEN GROUND)
To adjust the shear bar (item 1):
1. Loosen (slightly) the threaded rod (item 2) to remove
pressure on top of the shear bar.
2. Loosen the lock nut (item 4) and make the adjust-
ment by turning the bolt (item 5) until the shear bar
comes in contact with the cutting edge on the knives.
Then, loosen slightly the bolt (item 5) to eliminate
any possible contact with the shear bar.
3. Rotate the cutter head manually to verify the adjust-
ment. The recoended gap between the shear bar
and the cutting edges is ”zero”.
4. Securely tighten the threaded rod (item 2) and the
lock nut (item 4).
5. Manually check one more time if the cutter head
turns freely.
NOTE
: All bolts used for the shear bar adjustment are
special. Never used standard bolts.
