6.2. Blade replacement
Worn or damaged blades should always be replaced according to the guides on Pict 17 and 18. Blades
should be replaced in pairs in order to maintain disc balance. During blade replacement carefully

ATTENTION:
During operation pay attention if the mower is vibrating which would indicate
that the disc (discs) is operating with only one blade. Long-term mowing in this
state will result in permanent damage to the cutting bar. This is not covered by
the warranty. Take breaks while mowing and check weather all the blades are
present.
WARNING:
During blade replacement the tractor engine must always be stopped.
