Starting The Engine - Volvo Penta TAMD63L Instruction Book

Starting the engine

To keep smoke on starting to a minimum, the TAMD71B is fitted with air preheating (a starter element). This
starter element is found in the inlet pipe, and its activation time is controlled by a timer relay. On the TAMD63,
TAMD73 and TAMD74, which all have higher compression, different combustion chambers and a modified in-
jection system, a starter element is not required.
The starter element should be on for approx. 50 s for preheating the inlet air before cold-starting. After starting,
the element is switched on automatically for a further 50 s to reduce exhaust smoke during warming up and to
make the engine run evenly.
Note: On the TAMD73P and TAMD74 the electronic diesel control (EDC) system minimizes exhaust emissions
during starting. To raise the combustion temperature before starting the starter motor turns over the engine ap-
prox. 1– 4 revolutions (temperature dependent) before fuel is injected.
To ensure smoother running on a cold engine the idle rpm is increased to 800 rpm for a maximum of 2 minutes
when the engine coolant temperature is below +15°C (59°F). When the coolant temperature rises above 15°C
(59°F) the idle rpm is gradually reduced to normal idle speed.
Warning! Never use start spray or similar to start the engine. There may be an explosion in the inlet man-
ifold. Danger of personal injury.

Single lever control: Check that the lever is in
neutral "N". This means that the throttle control is
set to idling and the reverse gear is disengaged.
Dual lever control: Move the forward/reverse
lever into neutral in order to start. Pull the throttle
lever right back (idling position).
Insert the key in the key switch. Turn it to the "I"
position (operating position). All warning lights
will come on. (The high coolant temperature
warning light will go off after 20 seconds).
TAMD73P and TAMD74:
Activate the control position to be used by
pressing the red "Active Station" button.
The red and green buttons ("Active Station" and
"Neutral" respectively) light up to confirm that
the control position is active.
NOTE! If the red button is flashing, the con-
trol lever is not in neutral.
NOTE! For safety reasons, the control po-
sition can only be activated when the con-
trol lever is in the Neutral position.
(The engine cannot be started until the
control position is activated).
TAMD71B:
Cold engine: Turn the key to position "II" (pre-
heating). Release the key when the "starter ele-
ment on" indicator lamp comes on. Activation
time is approx. 50 secs. (timer relay). Do not at-
tempt to start the engine until the indicator light
has gone out.
Hot engine: Turn the key directly to position "III"
to start.
