8.7 Flail replacement
If the ails are excessively worn, replace them. In the event of partial breakage of the ail, replace both it and the
diametrically opposite one in order to maintain equilibrium.
To change the ails, lift the machine and work below it.
Raise the head by means of the tractor lift and support it in order to guard against any unintentional lowering of the lift.
Do not rely on the holding power of the hydraulic lift: insert trestles or mechanical struts
between the machine and the ground, to avoid the accidental descent of the head.
WARNING
Make sure that the PTO is disengaged, apply the parking brake, switch o the engine and remove the key from the
dashboard.
When replacing the ails, DO NOT REMOVE THE BALANCING WEIGHTS from their
original position.
WARNING
If irregularities or strange noises are noticed after changing the ails, contact FERRI
immediately.
WARNING
Replace bent or broken ails with new ails.
For safety reasons, never attempt to straighten the ails or to perform welding on them
because this can reduce their strength.
DANGER
Use exclusively original FERRI spare parts.
CAUTION
