e) Installing the Propeller
The propeller (1) is already correctly installed at the aluminium tappet ex works. Push this unit onto the motor shaft.
Observe that one of the two grub screws of the tappet (3) can be screwed in on the flattened side of the motor shaft
(2).
Now tighten both grub screws with a matching hexagon socket wrench. The grub screws should be secured against
coming loose with a drop of threadlocker varnish.
