P4 Raising and locking the feed roller
To unseize a rotor after jamming or to do specifi c servicing (anvil
replacement) it is most useful to be able to lock the feed roller in the
shredding chamber in its raised position. To do so, proceed as follows:
• An arm on both sides supports the feed roller. The L.H. arm (the one
with the drive components) has a latch.
• Turn the lip until the pen slides out.
(1)
• Hold the L.H. arm at the hydromotor by the handle and lift upwards
until the maximum lifting height is achieved.
(2)
• A stop securely locks the latching pin which causes the feed roller to
remain in this position.
• At that point, you can carry out the required maintenance work.
• To lower the feed roller simply release the latch. In order to prevent
the feed roller from dropping down hold the L.H. arm of the feed roller
whilst releasing the latch.
• Rotate the lip of the latch 180° until it engages in the small recess; this action will get the pin to
retract fully to allow to lower the feed roller.
• Finally, gently lower the arm of the feed roller to its lowest position.
Caution:
The feed roller is rather heavy and a gas spring keeps it in its lowest position.
When lifting, proper lifting procedures should be followed to avoid back injuries.

Removing chain guards
Caution:
Prior to removing a chain guard, always remember
to switch off the motor and to remove the key from the ignition.
This type of shredder has three chain drive. While all of these drive ar-
rangements are protected by large shielding panels, two of these chain
drives have each their own guard for reasons of dust sealing protection:
• Feed roller chain drive: This chain drive is integral with the arm which
supports the feed roller at the left-hand side. The cover is bolted down
into place with two M10 bolts (A/F 17). Remember to install the lock
washers when refi tting the cover, to prevent the bolts from coming loose.
