STARTING: check visually again that the propeller area is clear and call "Clear Prop" loudly. Pause. Turn on
the key switch, set the contacts to ON, then push the button in 5 seconds bursts. Release the button as soon
as the engine fires.
If the engine refuses to start after 5 or 6 attempts, close the controls and switch OFF the ignition before
investigation.
WARNING
!
Do not attempt to start the motor with the
throttles open.
Although unlikely, it is possible that an electrical circuit fault will allow the ignition circuit to remain live
with the ignition switches in the off position, it is therefore essential that before attempting to clear a
flooded engine with the foot throttle set to OPEN, you ensure that the aircraft has adequate clear
space forward for the operator to react to an inadvertent engine start up and to close the throttles. If
in any doubt, then chock the aircraft before carrying out this procedure.
Never attempt to hand start an engine by swinging the propeller! This practice is very dangerous
and could result in injury or death.
6.4. ENGINE WARM-UP
ROTATING PROPELLERS ARE ALMOST INVISIBLE AND CAN CAUSE INJURY OR DEATH!
Extreme care must be exercised during engine warm-up. Ensure that all spectators/children/pets
are kept well clear of the propeller and the propeller arc.
