4.1 - RUNNING IN
4.1.1 - The following precautions should be taken
during the running in period
1. Experience has shown that the first 50 hours of tractor
operation have a significant effect on the performance
and life of the engine.
2. From the first operation, the tractor must run at almost
full load of the engine. The engine should always be
allowed to reach a temperature of 60°C (140°F) before
being subjected to full load.
3. It is quite normal for oil consumption to be relatively
high during the running in period. During running in
therefore, check the engine oil level twice a day during
the first 50 hours of operation to avoid the risk of lubri-
cation failure.
4. During running in, frequently check the tightness of all
nuts, bolts and screws. The wheel nuts must be
retightened daily until their torque has stabilised (see
chapter 6).
4.2 - START-UP
IMPORTANT: Before starting the tractor, refer to the
Service Guide, chapter 5.
IMPORTANT: Before starting, never run the engine in a
closed space. Never run the engine unless you are sat
at the steering wheel of the tractor.
CAUTION: After a long standstill, to ensure
lubrication of the turbocharger bearings run
the engine on the starter for about ten sec-
onds.
4.2.1 - Starting the engine
1. Turn on the ignition key, the TC and DC symbols flash
on the right-hand screen of the instrument panel (Fig.
1).
NOTE: The numbers under T.C. and D.C., required for
the service engineer, correspond to the software ver-
sion.
2. Fully press down the clutch pedal (Fig. 2).
