Replacing the knives and knife mountings
Worn and/or damaged knives should be immediately replaced (
Fig. 31
). Replace knives, if
necessary, only in sets. When replacing, carefully inspect a knife mounting. If knife mounting
(
Fig. 30
), is worn, immediately replace two mountings (tightening torque 130 Nm / 96 ft-lb (Bł

NOTICE:
When operating pay attention whether there are no excessive vibrations of the mower which
may indicate that the disc(s) operate with 1 cutting knife attached only. Long-term cutting
with insufficient amount of knives will cause permanent damage to the cutterbar, not
eligible for a repair under the warranty. When operating check knives for completeness.
WARNING!
When replacing knives, the engine must be stopped and the cutterbar must lie
on the ground. PTO shaft must be disconnected. Discs should be perpendicular
to cutterbar.

WARNING!
-
Due to various windrow widths in the mowers (and therefore various
rotation directions of the discs), before mounting the knives check rotation
directions of each disc (
Fig. 33
).
-
Improper mounting of knives will cause mower's choking. When mounting
pay particular attention to knife's free rotation on knife mounting.
