the sensor (236), you could disable the no-stress device through its switch (289). This
way you can work manually by using the control shackle (picture 5). Please contact
an authorized technician anyway.
EXCESSIVE VIBRATIONS
The possible reasons for such a failure could be: unbalance of the cutting unit caused
by the inclination of one or more shafts that support the hammers; breaking down of
one or more hammers ; loosen driving elements. Find out the source of the problem
and contact a technician for its repairing.
MAINTENANCE
(Use the exploded diagram and the list of components at the end of the manual)
Before each checking, maintenance or cleaning operation to be carried out at the end
of every working session, please switch the tractor off.
We strongly advise you to wear working gloves.
Cleaning of the shredding unit:
Clean the machine as described in the
previous paragraph “ Accidental cases and
what to do accordingly ” and remove all
possible residues left inside the bio-
shredder. When doing so, please act very
carefully since the cutting heads are very
dangerous. Assemble everything back.
Cleaning, checking and replacing the
apron conveyor:
After every working day, we advice you
remove the protection housing on one side
of the hopper (191) by unbolting the four nuts (118) so that you can clean the apron
conveyor (145) and the driven roller (185) through the inspection overlay of the
hopper (picture 7). Please make sure that the apron conveyor is not too stretched
(there should be a 3/ 4 cm subsidence when pressing the upper part of the apron
conveyor itself at around 15 cm from its beginning). If so, loosen it by using the
threaded bars (187).
A too stretched apron conveyor leads to the breaking down of its joints. It can also
cause a decrease in the performance level of the machine. Through the same
inspection overlay, it is possible to evaluate the wear of the tubes of the apron
conveyor. If the wear exceeds 3.5 mm, please replace the tubes. Loosen the apron
conveyor by using the threaded bars (187) and replace a louver (171-172) or the
entire apron conveyor (145). In order for you to do so, take down the hydraulic
engine (92) by unbolting the two screws (24) and by pulling out the spring washers
(173) from the upper part. You have to pull out four of them if you are replacing a
