Shredding quality, machine integrity and
safety
depend on the care which will be devoted to these elements.
They must be replaced immediately if damaged.
Normal wear (specially rapid on sandy grounds or working with the machine too low) and bumps against obstacles
can cause distortions or cracks in the blades or rams, which can lead to:
• Worsening in the work quality,
• Increase in vibrations and consequent mechanical damages in the machine,
• Total or partial break of the blades and rams with consequent
projection of fragments at high speed.

Worn blades or rams:
The hole (
F
)
of the pin
should not be ovalized over 2mm from the
original diameter.
The length (
L
) of the blade or ram should not be reduced over 20
mm.
The pin fixing can be carried out with split pins or nuts,
according to the model of the machine.
Pins should be replaced if:
They are clearly bent or damaged in the thread: in particular check
(if welded) the welding integrity of the plate (
S
).
The tracking made by the wear of the blade or ram (
H
) is greater of
2 mm.
During assembly:
The selflocking split pins or nuts should be
changed every time.
Torque wrench setting for M16 nut: 100 Nm
Torque wrench setting for M20 nut: 250 Nm
Check that the pin with tooth or the pin with hexagonal head, CANNOT rotate in their seat on
the support, because this could cause an abnormal consumption.
Blades or rams: to be checked always before using the machine
to be checked immediately after an obstacle
