SERVICE AND MAINTENANCE
6DIHW\
Installations and adjustments can only be made by a
person with the required skills and quali
¿ cations and the
necessary knowledge of the machine in question.
Installations, adjustments and repairs must be undertak-
en with the engine stopped and the ignition key off.
All the moving parts must be in balance and stopped
and, when necessary, locked. Support the cutting table
and the reel in their top positions. Ensure that there is no
pressurized energy in the
À uid systems before opening
mechanical or hydraulic couplings. The gas accumulator
for the table, the air conditioning equipment, the radiator,
etc.
Double-check that there is no risk of injury when starting
the engine either during or after service measures.
Ensure that all periodic checks and cleaning are carried
out on time in compliance with the instructions so that no
such malfunctions may occur which can cause any risk or
hazard.
General Instructions
‡ Make sure you are skilled enough to service the
combine before undertaking any maintenance work.
If not sure, contact a quali
¿ ed service man.
‡ Get acquainted with the combine structure and the
following service instructions before undertaking any
work.
‡ Wear appropriate protective clothing.
‡ Use appropriate tools and other equipment.
‡ Handle the combine and any work materials in such
a manner that there is no risk of injuring yourself or
anybody else, or harming the environment.
WELDING
The regular service measures required do not involve
welding, but it may sometimes be necessary when doing
repairs. Only quali
¿ ed hot work operators are allowed to
weld.
Welding causes a considerable ¿ re risk. Clean the com-
bine carefully before undertaking any welding work and
make sure you have a
¿ re extinguisher handy. Appropri-
ate ¿ re watch shall be seen to.
The electrical system of the combine houses several
components with semiconductors. They get easily dam-
aged when there are voltage peaks caused by arc weld-
ing. The main principle is to detach any structures that
require welding. If any
¿ xed combine structures need to
be welded, take the following precautions:
‡ Switch off the master switch or disconnect one of
the battery cables.
‡ Disconnect connector A to the Comvision- display
unit inside the instrument panel. Fig. LH
‡ Disconnect the feeder cable to the control unit of
the Common-Rail motor. First remove the protec-
tive cover off the unit attached to the motor. Turn
the locking clip on the connector and pull the con-
nector open. Fig. CTA
‡ Disconnect the connector of SCR supply module.
