Pre-heating engine and oil
It is permissible to start an engine without pre-heating if the outside air temperature is not below
41
°F
(+5
°C). Pre
-heat the engine and oil if air temperature falls below
41 °F
(+5
°C). Use suitable air
heater or a dryer.
WARNING
Never use open fire to pre-heat an engine!
Blow hot air from the front into the hole around the prop (engine covered with fiberglass cowlings).
The temperature of the hot air should not exceed
212 °F
(100
°C) at air heater output. Warm up
the oil tank along with the oil in the engine. Pre-heat until cylinder head and oil temperatures
exceed
68 °F
(+20
° C).
Engine starting
1. Turn the propeller by hand (ignition switched off!)
2. Open the fuel valve
3. Set throttle lever to idle
4. Open the choke
5. Master switch to "ON"
6. Turn the key in the switch
7. Switch on ignition switches to "RUN"
8. Push the starter button to start the engine
9. Adjust engine RPM after starting
10. Close the choke

CAUTION
If the cylinder head and oil temperatures fall during parking. Start and warm up engine from time to
time between flights. Do not open choke when starting a hot engine.
Parking and taxiing
Check wheel brakes for freezing when parked outside and temperature is below zero. Check
wheels free rotation prior to taxiing (Grasp the propeller and pull the airplane). Heat the brakes
with hot air (to melt snow or ice). Frozen materials should not be removed by forced towing.
After winter operation
Clean the airplane thoroughly (hinges, especially the suspensions)
Lubricate airplane per Lubricating Chart
