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.
NOTE !
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 -10 °C may require assistance for the
aircraft battery!
1)
Check coolant level, that the engine oil tank level is sufficient for flight / test and that
the fuel is sufficient, on, and water free.
2)
Set throttle slightly off the idle stop.
3)
Switch on battery and alternator.
4)
Switch on ignition – verify that all gauges / alarms are correct.
5)
Switch on both fuel pumps – verify that all gauges / alarms are correct.
WARNING !
Ensure all personnel are clear of propeller and aware that the
engine is to be started.
6)
Operate fuel primer to aircraft manufacturers instructions (if installed)
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 (6 & 7) at 15 second intervals.
12)
See NOTES above for starting limitations.
13)
Allow engine to warm up at approximately 3000 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 system. In this
case the bleed procedure should be carried out without further running (see 13.3).
CAUTION !
During cold starts not more than 5 x 5 second start attempts in
any 3 minute period.
