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:

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 adjustingscrew

Shredders model
BNG are equipped with belts type SPBX
:
tension
of
such belts 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.
