13.2.10)Venting of lubrication system
Fill oil tank with approx. 2 litres (0,53 gal.US) motor oil. See Chapter 8). Start
engine and observe oil pressure indication. Within 10 seconds the oil
pressure must rise to min. 2 bar (30 psi). Otherwise stop the engine instantly
and vent suction line between oil tank and oil pump.
Remove suction line from oil tank and refill with oil using a funnel. By a few
manual turns of the propeller the pump sucks oil.
▲ WARNING: For safety, switch off ignition and remove ignition key!
Refit oil line and start engine again. After short idling, stop the engine and refill
oil level in the tank to max. mark. Do not overfill, otherwise oil would exit
through vent bore during operation. At oil level check the max. mark must not
be exceeded.
▲ WARNING: Always observe the engine while running from a secure
place.
