OPERATION 3.10 STARTING THE ENGINES
237
3.10.1 STARTING PROCEDURE
EMARK
Start the engines one after another, e.g. first rear engine (1)
then front engine (2). Both engines are started in the same way.
1. Insert battery main switch keys and turn to operating position.
EMARK
Start the engines with the safety lock lever (13), illustration
Z25492 in the fully rear LOCKED position. When the engines are
running move the safety lock lever fully to the front in FREE posi-
tion.
2. Insert key into the switch (1) and turn to operating position.
The warning buzzer (2) must give an acoustic test signal. If
the buzzer fails to function, corrective action must be taken.
3. Observe ECS display (3). Normally the basic display appears
on screen (3). If a FAULT message or INFORMATION item is
displayed, proceed according to section "ELECTRONIC
MONITORING AND CONTROL SYSTEM ECS" on page 92.
4. Set toggle switch (4) to low idle speed position.
5. Sound the signal horn (5).
6. Start the engines by turning starter switches (6 and 9).
EMARK
Each engine is equipped with a prelubrication system which
is activated by the starter switch (6/9). Turning and holding the
switch in the start position sends current to the prelubrication
starter solenoid which then prelubricates the engine. This sole-
noid timer prevents current from flowing to the conventional start-
ing motor until 17 kPa (2.5 psi) oil pressure has been achieved in
the cam oil rifle. After a subsequent 3 second delay, current is
then directed to the starting motors for cranking the engine.
7. Cold Weather Starting
To facilitate starting at low outside temperatures (below 0° C)
and with the engines cold, use the cold starting aid. Take into
account, that the prelubrication period will be longer at low
ambient temperatures. Inject starting fluid only after the prelu-
brication period is finished and the engine starts to crank.
Engage the starter and while cranking, apply metered
amounts of starting fluid using switch (8/11) until the engine
idles smoothly.
CAUTION
Use the cold starting aid only during starting and with the
engines cold.
