3. Preparation of the starter
Install the starting shaft to the
starter securely. Poor installation
swings the starting shaft, which is
dangerous.

Make sure that the starter rotates
to the direction shown in the
sketch. If the direction is reverse,
reverse the leads on battery.
Inserting the starter shaft

Insert the starting shaft into the
shaft cup securely.
Priming
6.
Without heating the glowplug, open
the throttle a little from the idling
position. Turn the engine using the
starter until the fuel is seen to reach
carburetor.
7.
Preparation of starting
Make sure that the transmitter
throttle stick is at the fully closed
position and the throttle trim at center
position, and make sure that idle-up
switch on the transmitter is off. Hold
the rotor head by hand so that rotor
cannot rotate when the engine is Started. Also,
steady the model with a foot on the landinggear skid.
Starting
8.
Connect the battery to the glowplug and start the
engine by applying the starter. When started, switch
off the starter and withdraw the starting shaft after
making sure the rotation of the starter shaft stops.
9. Stopping the engine
Fully pull down the throttle trim on the transmitter.
In case the engine does not stop.
Hold the rotor head, and pinch the silicone tube to
stop the fuel supply. If it still does not stop, pull off the
fuel tubing from the carburetor.
It is necessary to readjust the throttle linkage so that
the carburetor rotor is fully closed when the throttle
stick and throttle trim on the transmitter are fully
pulled Down.
