Loosen bolts (
A
, no.
4
) and (
B
, no.
1
) which fasten transmission to shredder frame.
Loosen adjusting screw counternuts (
H
and
D
).
Turn adjusting screw (
E
)
clockwise, and turn screw
(
G
), anticlockwise, up to get the tension desired (See the
table).
That operation allows transmission axis (
PR
) to be parallel to rotor axis.
Tighten bolts (
A
and
B
) and counternuts (
D
and
H
).
In order to check parallelism between transmission axis and rotor axis, follow the indications listed
below:
IF THE MACHINE IS COUPLED TO THE TRACTOR,
REMOVE THE CARDAN TRANSMISSION
Dismount the belt safety guard.
Put a scale on the edges of the rotor pulley and rotate it until it touches the edges of the other pulley.
Both pulley edges shall touch the scale; otherwise, screw or unscrew adjusting screw (
G
) accordingly, after
loosening screws (
A
and
B
).
Belt tension must be restored within the first 3 working hours.
Afterwards, check belt tension periodically.
If rotor rotation speed decreases and belt tension can not be restored correctly,
change belts.
