Starting and driving
Engine shutdown
There is risk of post boiling and of damage to the
turbocharger if the engine is switched off with-
out cooling. The power must not be switched off
before the engine has stopped.
If the engine is fitted with a battery master switch
and an SCR system, the SCR system must run for
a while after the engine has been switched off to
allow it to cool down. During this period the
power must not be cut using the battery master
switch.
The battery voltage must remain on for a few
seconds after the 15 voltage is switched off so
that the control units can store the values and
switch to standby mode.
10 prohibited engine shutdowns will cause a
torque reduction (70% of fuel volume). Reset the
engine by switching it off correctly once.
1. Run the engine without a load for a few min-
utes if it has been run continuously with a
heavy load.
2. Switch off the engine.
Checks after driving
Block the starting device when working on the
engine. If the engine starts unexpectedly, there is
a serious risk of injury.
There is always a risk of sustaining burns when
an engine is hot. Particularly hot parts are branch
pipes, turbochargers, oil sumps, and hot coolant
and oil in pipes and hoses.
Check the coolant level following the first start.
Top up with coolant as necessary.
1. Check that the power supply has been cut.
2. Top up the fuel tank. Make sure that the filler
cap and the area round the filler opening are
clean to avoid contamination of the fuel.
3. If the engine is equipped with an SCR sys-
tem: Top up the reductant tank. Make sure
that the filler cap and the area round the filler
opening are clean to avoid contamination of
the reductant.
4. If there is a risk of freezing, the cooling sys-
tem must contain enough glycol. See the sec-
tion Risk of freezing
.
5. If the temperature is below 0°C (32°F): Pre-
pare for the next start by connecting the en-
gine heater (if fitted).
