9.7 Solving problems
9.7.1 Blockage of the discharge screw
If you notice that the shredder suddenly slows down a great deal, quickly check whether the
discharge screw is still rotating. In extreme cases, a piece of wood can become jammed and block
the screw. Unblocking the discharge screw
• Immediately stop wood feed by pushing the control
lever forwards.
• You can use a special handle (that is concealed
underneath the feed hopper) to change the direction
of rotation of the screw. To do this, move the small
handle forwards.
• Move the handle forwards and backwards so that
the screw alternately rotates to the left and to the
right for a short time.
Caution : You may only allow the screw to rotate in
the opposite direction for a short time. Otherwise,
chippings underneath the collector will be com-
pressed. This can result in deformation.
9.7.2 Blocking of the rotor
During the shredding, the machine has become “choked” and the engine has stopped. The
engine cannot be started because the rotor has become jammed on a piece of wood. In this case,
unblock the rotor as follows:
• Stop the engine and remove the start key (9,4).
• Remove the lateral safety covers (11.3.2).
• Open the shredding chamber (11.3.3).
• Unhook the lever found on the left-hand side of the machine.
• This lever has two functions for unblocking a jammed rotor:
a. To lift the feed roller in order to remove the garden waste that is located underneath the
roller.
b. To dislodge the rotor that is possibly jammed on a piece of wood.
a. Lifting the feed roller
• Fit the eye at one end of the lever down over the shaft journal on the left-hand side of the
feed roller.
