Carefully tap shaft W into cap U until it blocks.
If you find a rotary encoder assembly A8 inside this construction kit, you can continue with drawing 7. Insert the wires of R3 into the openings of component R2 as indicated in drawing 4, respecting the colour indications.
Solder the wires onto the rotary encoder R1, as indicated in drawing 5 and 6.
Place component W/U as assembled in drawing 1 onto t he rotary encoder shaft. There is a small indentation in the rotary encoder shaft. The opening of component U contains a small ridge, which fits exactly into this indentation. Make sure ridge and indentation fit completely.
Connect component M to component A8, making sure no glue comes into contact with the rotary encoder, with the rotary encoder shaft or with component W/U.

CAUTION! The servos cannot be connected as shown in picture 17, 18 and 19. The connector of the servos has to be cut off and the isolation of the wires should be removed somewhat to enable the wires to be soldered directly on the PC-Board, due to lack of space for connectors!

Place the plate with circuit board onto the lower casing, and guide out the rotary encoder assembly and the light between the casing and the circuit board. Mind the proper positioning of the plate. Use the positioning notch to find the right position. Cement the plate to the lower casing by applying a few drops of glue.
