First start of the motor
Properly attach the motor to the model or the test stand using all four screws. We don´t recomended
long running on stand due to vibrations, which is another than in case of mounting in the fuselage. If
you use testing stand, do not screw the engine hard, for example on a steel weldment, but always
use at least a wooden board, etc., but not the silentblocks! Connect the ignition source (4.8 - 9V, min.
capacity of 1500 mAh). Connect the fuel tank.
Make sure that the ignition is switched off
-
close the choke
-
5-6 x crank the motor in order to suck fuel

If after about 5 attempts, the engine does not start, repeat the procedure again
Note : ignition is equipped with a security protection function, because if it is turned on and the
motor is more than a minute at rest, the ignition is switched off. In this case, it is only the ignition off
and on again. For more information see the instructions of electronic ignition.
