Starting the engine
32
Start the engine
Start using the ignition switch
Turn the key to position III. Release the key and let it
key spring back to position I as soon as the engine has
started.
Starting with the starter button
Press the starter button. Release the button as soon
as the engine has started. Please note that if you start
from an alternative control station, the starter key at
the main control station must be in position I.
Overheating protection
If the starter motor is engaged for its maximum activa-
tion time (30 seconds), the starter motor circuit is cut
automatically to protect the starter motor from overhea-
ting. Leave the starter motor to cool for at least five
minutes (if possible) before making a new start at-
tempt.
Read the instruments and warm the
engine up
Allow the engine to idle for the first ten seconds, and
check that instruments and warning displays show nor-
mal values. Check that no warning lamps flash on the
alarm display.
Then warm the engine up at low speed and low load, so
that reaches normal operating temperature before full
power is used.
IMPORTANT! Never race the engine when it is
cold.
