Start the engine
If a station is locked the engines can only be started
and stopped from this station.
Start using the ignition switch
Start using the ignition switch III. Release the key and
let it spring back to position I as soon as the engine has
started.
If repeated start attempts are needed, the key must be
turned back to position 0 first.
Stop cranking if the engine does not start within 20
seconds.
Starting with the starter button
Press the starter button for each engine. Release the
button as soon as the engine has started.
If you start from a secondary station, the starter key at
the main control station must be in position I.
Stop cranking if the engine does not start within 20
seconds.
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 over-
heating. If possible, leave the starter motor to cool for
at least five minutes before making a new start attempt.
Read the instruments and warm the
engine up
Allow the engines to idle for the first ten seconds.
Check that instruments and warning displays show
normal values.
Check that no messages are displayed and no warning
signs are showing. If a fault is registred, please refer
to section Fault Handling page 55 for further infor-
mation and recomended actions.
Warm the engine up at low speed and low load, so
normal operating temperature is reached before full
power is used.
IMPORTANT!
Never race the engine when it is cold.
