Glue a wooden wheel (4) on a wooden wheel (3) as shown. Look to it that the holes
are exactly above each other. (Check with the welding wire!)
Deburr the welding wire (10) at both ends with a engineer´s file. Then insert the
welding wire (10) into the hole (ø 4mm) as shown, so that it extends 20mm into the
base frame. .
Glue the switch (8) into the opening of the base plate (1). Agglutinate the complete
base out of the parts 1, 2a, 2b as shown. Let it dry well.
After drying glue both wheels centrical on the base. Drill the 2mm hole at a distance
of 5mm to the center of the wooden wheels as shown.

Cut o the PVC hose a 25 mm long piece and clip it on the welding wire (10). Moreo-
ver clip on the washer (14) of tree part 1. Place the wooden disc (3) over the washer.
Afterwards clip on tree part 1. See picture! . When you insert the battery into the
battery holder, the function of the LED´s can be checked.
Cut o the red an black welding wire (12 + 13) 5 pieces, each with a length of 70 mm.
Strip isolation on both sides and tin them.
Bend the legs of 6 LED´s by 90° as shown and attach them with the hot glue gun to
the indented folds of tree part 1.
Solder the anodes (long legs) of the LED´s with cables (red) together, so that all
anodes are linked. Do the same with the cathodes (short legs). Use the black cables.
In Addition cut o the red welding wire (13) a 200 mm long piece. Strip isolation
on both sides and tin them. Solder one end on an anode and thread the other end
upwards through the hole in tree part 1. Solder the red connection cable of the
resistor on the same anode.
Cut o the black welding wire (12) a 70 mm long piece. Strip isolation on both sides
and tin them. Solder one end on a cathode of the LED and attach the other end to a
washer (14). If the solder doesn´t hold on the washer remove the nickle layer with a
engineer´s file at the soldering point. Place the washer over the hole in the tree part.
Follow the circuit diagram (page 7).
Cut o the red welding wire (13) a approx. 100 mm long piece. Strip isolation on
both sides and tin them. Solder one end on the resistor (9) and thread the other end
upwards through the ø 2mm hole. Solder the free leg of the resistor on the external
switch connection and the red cable of the battery holder (11) on the middle switch
connector. Place a soldering point on the welding wire (10) at the lower part in the
underframe. Solder the black wire of the battery holder (11) on the welding wire
soldering point.
