4.1.2 Engine Start
1. Engine Master – “ON”
2. Glow plug lights – “ON”
3. Glow plugs – „OFF“ (the glow plug lights extinguish after not more than 15 seconds)
4. Propeller Area – Clear and Save
5. Engine – “Start”
Do not operate the starter for more than 10 seconds.
At ambient temperatures below -22°C it is possible that the engine will not run at the first
attempt. In this case wait 60 seconds between the start attempts.
6. Oil Pressure rise within 3 seconds
7. Voltage, Electric Load – Check indication
8. Alternator switch – “ON”
The alternator switch should not be turned ON before starting the engine. Turning the
alternator switch ON while the engine is not running reduces the service life of the
alternator system and drains the battery unnecessarily.
4.1.3 Warm Up
1. Oil Pressure – “CHECKED” (refer to chapter 2.5.6.1 and 2.5.7.1)
2. rpm (Propeller) – “CHECKED” 710 +/- 30 rpm
3. Idle – 30 seconds
4. Thereafter power as required, max. 50 % load until oil temperature >50 ºC (> 122 ºF) and
coolant temperature >60 ºC (> 140 ºF) and Gearbox Oil temperature >35 ºC (> 95 ºF).
At low oil temperature high oil pressure may occur which could lead to an oil pressure
warning. In this case reduce power setting until the caution disappears and conduct the
warm up with this reduced setting.
At low gearbox oil temperature it may occur that the ECU-Self Test is not performed
successfully. In this case warm up the engine and retry the ECU-Self Test at higher gearbox
temperatures.
