Operation
Diagnostic information
The indicator for the diagnostic button starts to flash if the
diagnostic function registers malfunction in the EDC sys-
tem.
Corrective action:
1. Reduce engine speed to idle.
2. Acknowledge the message by pressing the diagnostic
button.
3. Release the diagnostic button and make a not of the
diagnostic trouble code (DTC) that is flashed out.
The diagnostic trouble code (DTC) remains stored as
long as there is a malfunction and can be noted later.
4. Look up the diagnostic trouble code (DTC) in the “Diag-
nostic function” chapter and carry out the recommended
remedies accordingly.
Alternatively: If the gear control, warning display and
other instrumentation is functioning normally, the opera-
tor can continue the journey and remedy the malfunction
at a later time.
NOTE! In the “Diagnostic function” chapter there is more
information about the diagnostic function, reading off diag-
nostic trouble codes (DTCs) etc.
Cruising speed
Avoid running at full speed to obtain the best operating
economy. We recommend a cruising speed of at least 10%
lower than the maximum rpm at full speed (wide open throt-
tle). The maximum rpm at full speed can vary depending
on choice of propeller, load and sea conditions, etc., but
should be within the wide open throttle range.
Wide open throttle range:
KAD/KAMD44P .................................. 3700–3900 rpm
KAD/KAMD300 ................................... 3700–3900 rpm
There could be several reasons for the engine failing to
reach the wide open throttle range, see the chapter “Trou-
bleshooting”. Use a propeller with a greater pitch if the en-
gine speed exceeds the wide open throttle range. Get in
touch with your Volvo Penta dealer for advice.
Overloading
In all parachute towing, water skiing, etc. full throttle speed
must not be less than 3600 rpm.
Towing must only be done at half throttle.
