Nose Wheel .............................................CHECK condition & pressure.
10. “Pulling Through” The Engine
Before the first flight of the day the engine must be “pulled through” by hand. This is the process
of turning the engine over by turning the propeller by hand. The compression of each cylinder in
turn will be felt a resistance as the propeller is turned. The engine should be rotated for a count
of at least 8 compressions.
Master Switch............................................OFF
Ignitions.....................................................OFF
Throttle......................................................Closed
Propeller....................................................TURN by hand & observe engine for odd
noises or heavy movements. Check for
regular compression.
CAUTION:
Prior to pulling through the propeller by hand, the engine must be cold, both ignition circuits & the
Master Switch must be switched OFF, the brakes applied & throttle closed.
WARNING
A hot engine may fire with the ignition/s switched OFF.
DO NOT pull through a hot engine.
CAUTION
Several causes of irregular compression – such as poorly sealing valves – can lead to extensive
engine damage if not addressed. The Jabiru 3300 Engine Instruction & Maintenance Manual
provides additional details.
