Adjusting the counter-knives (if fitted)
To work correctly, the counter-knives must be positioned at least 5 mm from the flails. Make sure this distance is
complied with.
WARNING!
This operation is best performed with the machine folded in the road travel position and rested on
the ground.
Where necessary, pull the counter-knives forward, making sure you loosen all the screws, see Figure 6.4, that fasten
them to the enclosure. This operation should also be performed when the tools become worn following several hours of
operation and the height is no longer correct.

DANGER!
Adjusting the counter-knives involves lifting the machine and must therefore be carried out using
suitable equipment at a workshop a
