The indications for monitoring important engine-parameters during operation are integrated within two instruments (CED 125; AED 125) in the right half of the instrument panel. The engine can only be operated with the ENGINE MASTER switch ON. The ECU receives its electrical power from the battery even if the battery is disconnected from the electric power distribution system by the ELECTRIC MASTER switch.

7.9.2 OPERATING CONTROLS
Power lever
The engine performance is controlled by the power lever, situated on the large center console. ‘Front’ and ‘rear’ are defined in relation to the direction of flight. Friction can be adjusted by pulling up the friction handle (high friction) or pressing the button (low friction) on top of the lever.
This lever is used to set the desired engine power LOAD (%)
Lever forward (MAX) = Full power
Lever to rear (IDLE) = Idle
The ECU controls manifold pressure, injected fuel quantity and propeller speed according to the desired engine power preselected with the power lever.
The propeller governor is flanged onto the front of the engine. The propeller governor oil circulation is a separate oil circulation system. Following a loss of oil pressure the blades go to the finest possible pitch (maximum RPM), thus allowing continuation of the flight according to 3.2.6 -DEFECTIVE RPM REGULATING SYSTEM.
CAUTION
Following governor failure the RPM should be adjusted using the power lever. Every effort should be made not to exceed 2500 RPM.
CAUTION
The power lever should be moved slowly, in order to avoid over-speeding and excessively rapid RPM changes. The light wooden propeller blades produce more rapid RPM changes than metal blades.
Doc. No. 6.01.05-E Revision 3 26-May-2003 Page 7 - 22
WARNING
It is possible that the propeller blades remain in the position of highest pitch in case of a malfunction of the engine control unit. In this case the reduced engine performance should be taken into consideration.
ELECTRIC MASTER
The key can be switched into three positions:
OFF
disconnecting battery power
ON
connecting battery power to the power distribution system
START
starting the engine
ENGINE MASTER
The engine can only be cranked with the ENGINE MASTER switched to ON. To shut down the engine the ENGINE MASTER is switched to OFF.
