13. Avionics master switch
- on.
14. Warm engine
- 2 000 rpm for 2 minutes, then
2 500 rpm until oil temp is 50 °C
(122 °F).
CAUTION
The starter should be activated for a maximum of 10 seconds, followed by 2 minute pause
to allow the starter to cool.
Verify the oil pressure, which should increase within 10 seconds. Increase the engine
speed only if oil pressure is steady above 2 bar (29 psi).
At an engine start with low oil temperature continue to watch the oil pressure as it could
drop again due to the increased resistance in the suction line. Increase engine rpm only as
required to keep oil pressure steady.
To avoid shock loading, start the engine with the throttle lever set to idle or 10% open at
maximum, then wait 3 seconds for engine to reach constant speed before accelerating
engine rpm.
