Check first
Always check on following points, before starting the
engine:
• Oil level
• Coolant level
• Is the raw water seacock opened?
• Is the main electrical switch ‘on’?
• Is the gearbox lever in the neutral position?
The starting procedure
1. Prior to starting the engine, position the throttle lever
at half of its travel, without engaging the gearbox.
2. Turn the key from the ‘off’ position one step further
to the right, to the ‘on’ position. The monitoring lights
for oil pressure, charging currents and pre-heating
will light up and the buzzer is audible.
3. From the ‘on’ position turn the key one step further
to the right, to the ‘pre-heating’ position. Now only
the pre-heating monitoring light is burning. Keep the
key about 6 seconds in this position (at an ambient
temperature of 15° C or more).
Note
:
The time required for pre-heating the engine is de-
termined by the ambient temperature. The lower the
temperature, the longer the pre-heating procedure will
take. At freezing temperature, it may take as long as 20
seconds; and up to 10 seconds at temperatures of up to
7 degrees. Do not pre-heat the engine any longer than 1
minute maximum.
4. The turn the starter key one step further to the right,
to the ‘start’ position and release the key as soon as
the engine springs to life; the key will return auto-
matically to the ‘on’ position, where it will remain
parked as long as the engine is running. Have the
engine running at idling revolutions during a short
period of time, so that the engine will warm-up to
some extent.
Stop the starting procedure if the engine
does not come to life within 10 seconds.
Release the key and wait till the starter
motor has come to a complete stand-still
before giving it another try.
Do not have the starter motor running during more than
30 seconds, in order to avoid damage by overheating.
