Starting and running
Charge air temperature
The engine management system has the follow-
ing alarm levels for high charge air temperature.
• Alarm at 70 C (158°F).
• Alarm or engine shutdown at 80°C (176°F).
Charging indicator lamp
If the lamp comes on during operation: Check
and adjust the alternator drive belt according to
the section
.
If the charging indicator lamp is still on, this
could be due to an alternator fault or a fault in the
electrical system.
Belt transmission
When the belt transmission is new, it may make
a squeaking noise when running. This noise is
normal and disappears after 50-100 hours of op-
eration. The noise does not affect the service life
of the belt transmission.
Engine shutdown
IMPORTANT!
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.
1.
Run the engine without load for 3 minutes at
the nominal engine speed.
2.
Switch off the engine via the coordinator and
allow the engine to run until the gas has run
out and the engine stops.
3.
Close the manual fuel cock.
Checks after running
WARNING!
Block the starting device and switch off the man-
ual fuel cock 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 turbo-
chargers, oil sumps, hot coolant and oil in pipes
and hoses.
IMPORTANT!
Check the coolant level following the first start.
Top up with coolant as necessary.
1.
Check that the manual fuel cock is turned off.
2.
Check that the power supply has been cut.
3.
Check that the cooling system contains
enough glycol according to the Scania in-
structions. See the section
4.
If the temperature is below 0°C (32°F): Pre-
pare for the next start by connecting the en-
gine heater (if fitted).
