9.1 Starting Procedure and Warm–up
Starting
The settings, start and warm–up procedures for the first start of a newly installed engine are
obviously to be treated with the greatest care. However, all engines supplied by Austro Engine
GmbH will have been fully run–in and performance–tested prior to shipping.
If the engine fails to start after three attempts (normal
maximum starter engagement per attempt of five seconds)
there is something incorrect!
(Fuel, ignition, or outside air temperature).
Starting between -5 °C and below may require assistance
for the aircraft battery!
1) Check coolant level
2) Check engine oil tank level is sufficient for flight / test
3) Check fuel level, fuel condition (no water contained); set fuel master “ON”
4) Set throttle slightly off the idle stop.
5) Switch on battery and alternator.
6) Switch on ignition – verify that all gauges / alarms are correct.
7) Switch on both fuel pumps – verify that all gauges / alarms are correct.
8) Switch on one ECU supply – verify error light on continuously (switch off).
9) Switch on second ECU supply and verify error light on continuously (switch off).
10) Switch on both ECU supplies and verify error light on continuously.
Ensure all personnel are clear of propeller and aware that
the engine is to be started.
9) Crank the engine for 5 seconds (or less if the engine starts).
10) If the engine fails to start, recheck switch positions and alarms.
11) If cold start – repeat (9) at 15 second intervals.
12) (See NOTES above for starting limitations).
13) Allow engine to warm up at approximately 3 000 RPM to 50 °C.
14) Check that the rpm rise is smooth and trouble free.
15) A sudden liquid coolant temperature rise indicates air trapped in the coolant system.
In this case the bleed procedure should be carried out (see 13.3)
