4.8 TINES
The blades fitted on the implement are suitable for soil of a nor-
mal consistency. Check them daily to make sure that they are in
a good condition and not worn. If the blades should accidentally
bend (or break) during work, they must be immediately replaced.
Make sure that the new blades are mounted in exactly the same
positions as the old ones. If several blades must be replaced, it
is advisable to demount and remount them one at a time in
order to avoid positioning errors. The sharp side of the blades
must point towards the direction in which the blade rotor turns.
DANGER
Blade replacement is a dangerous operation.
Proceed in the following way to change the blades:
▪
Park the tractor on a flat surface with the machine
hitched, then raise the machine with the power lift
▪
Insert two strong bearing stands at the sides of the ma-
chine
▪
Lower the machine on to the stands, turn off the tractor
engine and apply the parking brake
CAUTION
If blades must be changed, make sure that the new ones are
mounted in the same positions as the old ones.
