4 - OPERATING INSTRUCTIONS
STARTING THE UNIT
Starting the engine
Your tractor will guarantee reliable service if care is taken
during the running−in period (first 50 hours of work), and
if the maintenance recommendations in section 7 (Main-
tenance) are carefully followed.
Before operating the tractor, ensure that you are thor-
oughly familiar with the location and operation of the con-
trols.
Starter switch
To obtain the three starter key-switch (1) functions, press
the key and turn it to the following positions:
A No power supply to any of the circuits (key can be re-
moved). Engine stopped: automatic activation of fuel in-
jection cut-off.
B Standby for engine start up. Operation of indicators and
instrument cluster. Power supplied to various circuits.
C Engine starting: if released, the key returns automati-
cally to position (B) .

Starting the engine
1. To start the engine it is first necessary to connect the
battery to the electric system with the specific device
(external mechanical isolator or push-button inside the
cab).
2. If the tractor has not been used for some time, or is
started up for the first time in low outside temperature
conditions, operate the fuel pump starting lever ap-
proximately twenty times and allow the engine to run
for
5 ÷ 10 seconds with the injection pump in the “stop”
position.
3. Press down the clutch pedal, place the shuttle con-
trol lever in neutral to close the starting safety device
switch.
4. Move the throttle lever to around the half way position.
5. Turn the starter key to position (C) figure 1 . Release
the key as soon as the engine starts.
NOTICE: If one of the warning lights illuminates to signal
a fault, check and repair the faulty part. If the warning light
continues to signal a fault, have the machine checked by
your dealer.
Before accelerating or starting the tractor, allow the en-
gine to idle at
1000 RPM for 30 seconds to ensure that
the turbocharger is correctly lubricated.
When starting the engine after extended periods of non-
use, avoid using the hydraulic system immediately. All the
moving parts need to be lubricated properly before they
are subjected to full load.
Especially when the external temperature approaches
0 °C ( 32.0 °F ), run the engine at 1300 - 1500 RPM for
approximately 5 minutes in order to heat the oil in the
rear transmission to working temperature.
Starting in low outside temperature
When the outside temperature is low and the engine is
cold, cover the radiator before starting so that the engine
coolant can quickly reach the correct temperature. Then
remove the cover. Note too the following warnings:
• To avoid running down the battery, any single engine
starting attempt should not last longer than 15 s ; if,
however, the engine fires but does not start, continue
the attempt up to a maximum of
30 s .
• Wait at least one minute between attempts to start the
engine.
• To avoid excessively running down the battery, do not
make more than six attempts to start the engine.
With outside temperatures below 0 °C ( 32.0 °F ), in order
to prevent separation of the paraffin components in the
diesel fuel, leading to a reduction in fluidity and subse-
quent fuel supply problems (especially when starting the
engine), mix the diesel fuel with the antifreeze (or a simi-
lar product) in the proportions described on the container.
The antifreeze must be mixed with the diesel fuel before
there is any sign of paraffin separation; adding it later will
have no effect on an engine if the cold has already caused
the engine to stop running or prevent it being started.
Put the antifreeze in the tank first, followed by the diesel
fuel.
The antifreeze will ensure that there is an optimum fuel
supply to the engine without reducing performance,
even where the external temperature drops below
-20 °C
( -4.0 °F ).
