MIKRON III A OPERATING INSTRUCTIONS
5.0. Operating Instruction
Observing instructions for operation and maintenance is a prerequisite
for engine operational reliabi ty.
5.1. Before Starting the Engine
-- 'Ignition magnetos nOFF"
-
Daily Service completed ?
Open throttle and check throttle lever for free motion within full
range of its travel
Open choke, check for free motion within full· range of travel and
shut choke
Turn the propeller by hand for several revolutions and make sure the
starting spark boost mechanism is operating properly
Check for any irregular sound or engine turning resistance reason

Adjust engine speed to 1 000 rpm as soon as-the engine starts. Shut the
choke and make sure that oil pressure is indicated within 10 seconds.
Starting of the M III A engine is accomplished by turning of the
propeller on the ground and the MIll AE engine by pulling at the
starter lever. If the engine is equipped wi th both magneto's without
starting spark boots mechanism, if is necessary to switch on the
starting buzzer when starting theeingine.
It is appropriate, when starting a cold engine in low ambient
temperatures, to provide for a slight fuel excess by turning the engine
several times with ignition magne~tos' swi tched O~F and the fuel cock
OPEN, eventually to inject fuel into the inlet manifold by means of the
acceleration pump actuated.by repeated rapid opening of the throttle.
Preheating the engine and oil tank by means of hot air is recommended
in ambient air temperatures N=low - 5 deg. C.
