2. OIL RADIATOR AIR CONTROL SWITCH. The Oil Radiator Air Control switch controls the

electric actuator of the oil radiator air outlet flap, located midway along the bottom of the air scoop.

The switch has four possible positions: AUTOMATIC, OPEN, CLOSE, and OFF.

 AUTOMATIC. This is the standard position of the switch and should be set for all normal

operations. When set to AUTOMATIC, a thermostat automatically starts and stops the actuator

to move the oil radiator air outlet flap, depending on oil temperature.

 OPEN. The oil radiator air outlet flap can be opened manually by setting the switch to the OPEN

position in case automatic control of the flap fails, resulting in an abnormal oil temperature

reading on the Engine Gauge.

 CLOSE. The oil radiator air outlet flap can be closed manually by setting the switch to the

CLOSE position in case automatic control of the flap fails, resulting in an abnormal oil

temperature reading on the Engine Gauge.

 OFF. Control of the oil radiator air outlet flap is disabled.

3. LANDING LIGHT SWITCH. The Landing Light switch is used to turn the landing light on and off

by setting the switch to the corresponding position. Retraction and extension of the landing light is

controlled automatically by mechanical means when the gear is operated. A safety switch is

incorporated into the landing light circuit to cut off current to the light when it is retracted.

Keep ground operation of the landing light to a minimum to prevent overheating and

damaging the unit.

4. LEFT-HAND FLUORESCENT LIGHT RHEOSTAT. This switch controls the left fluorescent

instrument panel light. To turn the light on, first set the switch to the START position, then adjust

intensity between the ON and DIM settings. Note, the right fluorescent light is controlled by the

Right-hand Fluorescent Light rheostat located on the Electrical Control panel.
