10.3.4) Engine start
▲ WARNING! Do not take the engine into operation if any person
is near the aircraft.
Fuel cock.................................... open
Starting carb.............................. activated
◆ NOTE: If the engine is already in operating temperature,
start the engine without choke.
Throttle lever. ............................ set to idle position
Master switch. ........................... on
Ignition. ...................................... both circuits switched on
Starter button. ........................... actuate
■ CAUTION: Activate starter for max. 10 sec. only (without
interruption), followed by a cooling period of 2
minutes!
As soon as engine runs, adjust throttle to achieve smooth running at
approx. 2500 r.p.m.
Check if oil pressure has risen within 10 seconds and monitor oil
pressure. Increase of engine speed is only permitted at steady oil
pressure readings above 2 bar (30 psi).
At an engine start with low oil temperature, continue to observe the oil
pressure as it could drop again due to the increased flow resistance
in the suction line. The number of revolutions may be only so far
increased that the oil pressure remains steady.
De-activate starting carb.
■ CAUTION: Since the engine comprises a reduction gear with
shock absorber, take special care of the following:
To prevent impact load, start with throttle lever in
idle position or at the most up to 10% open. For the
same reason, wait for around 3 sec. after throttling
back to partial load to reach constant speed before
re-acceleration.
For checking the two ignition circuits, only one
circuit may be switched off and on at times.
■ CAUTION: Do not actuate starter button (switch) as long as
the engine is running. Wait until complete stop of
engine!
