4. Propeller (if applicable)
- AUTO.
5. Magneto / ignition switches
- on.
6. Fuel selector

open if not.
10. Propeller area
- clear of people and obstructions.
11. Starter
- engage (maximum 10 seconds).
Immediately after start-up:
12. Throttle
- adjust for smooth running
(approximately 2000 rpm).
13. Oil pressure
- increase within 10 seconds.
14. EFIS switch
- on and verify battery charging.
15. Avionics master switch

16. 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.
