OPERATION 3.9 STARTING THE ENGINES 3.9.1 STARTING PROCEDURE REMARK 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. 2. Insert key into the switch (1), illustration Z 21758 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 80. 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). REMARK 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. Use the cold starting aid only during starting and with the engine cold. REMARK Never operate the starter longer than 30 seconds at a time in order to avoid damage.
If the engine does not start within the first 30 seconds, wait 2 minutes before cranking again. 8. As soon as the engines are running, check display (3) for messages. 213 CAUTION
