Starting the engine
To start the engine, pull on some working gloves. Never start the engine alone! Ask a
reliable and strong person to hold your model. Do not trust mechanical anchorage in
the ground, on fences or something similar. Approx. 20 kp of thrust is an enormous
force!
The rst start of the day:
1. Close the Choke valve completely.
2. Open the throttle a bit more than required for normal idle.
3. Ask a reliable and strong person to hold your model.
4. Switch on the ignition
5. Flip the engine, without any extra sucking in! The engine will start, when the car-
buretor has sucked in enough gasoline with closed choke and will stop after a few
revolutions.
6. Flip the engine a second time with closed choke.
7. Open the choke.
8. Flip the engine, until the engine starts to run constantly.
9. Run the engine with increased idle for about 10 seconds.
10. Accelerate to 25% throttle, to warm the engine up for about 30 seconds until you
taxi to the runway.
If your engine had run during the last hour:
1. Close the choke valve completely
2. Open the throttle valve a bit more than required for normal idle.
3. Ask a reliable and strong person to hold your model.
4. Flip the engine once with the ignition switched o.
5. Open the choke valve.
6. Switch on the ignition.
7. Flip the engine, usually it will start immediately.
8. Warm up the engine as described above.
Ignition safety shut o
Due to a safety shut o feature, the ignition will automatically shut o after one min-
ute without turning the propeller. This safety feature can easily become a trap, if you
get disturbed by anyone, while starting your engine. If you go on after a minute and
forgot to switch the ignition o and on again, you will ood your engine more and
more with every ip...
Switch o your ignition with the battery switch, after every ight. A small current is still
owing, when the ignition is on stand by. This small current will discharge your bat-
tery. The ignition has to be switched o after every ight with the ignition switch!
