@ fa: Yes indeed it is inspired from the north young blood but the step will be different. Very small board for my girlfriend...
@ OAC & doughboyshredder: I will check the wires and post a photo :-) It would be very nice if I dont have to turn and readjust everything because I have nearly finished the machine...

feeding the sander from the backside is really very dangerous
DO NOT TRY IT
the motor i used can be changed from clockwise spinning to anticlockwise by swapping contacts
It depends if there's a reversible motor in the machine, if there is...just switch red and white. If not? You may be hosed unless you want to dis-assemble the motor.

No.
240v. Reversing L1 and L2 does nothing. With a 110v motor you would be correct.
Is there a nameplate on the motor? If so make sure it only says 220 and not 110/220. Pretty sure from the picture and wire description you posted, that it is a single voltage dual rotation motor. If I am correct you need to switch the black and the red. So you would end up with L1 (Line voltage 1) going to blue and red, and then L2 (the other Line voltage wire) going to black and yellow.
Now it looks more like a 3-phase motor "1-phase enabled"...?
Nameplate?
Where is the capacitor?
I don't know about your electrical system in Switzerland. There should be three(3) cables feedeing the motor, in a 1-phase system.
The swedish example:
In Sweden we have:
L = phase
N= zero (in a perfect system this is 0V and NOT ground) Always blue.
and ground (green/yellow)
Three phase motors up to approximately 0.75 kW can be converted to single-phase motors, the installation of a capacitor that is connected between two of the motor connections. 1-phase net then connected to one of these, and for the vacant connector. Direction changed by 1-phase net connected to the second capacitor connection.
The engine must be Δ-connected, 1-phase effect gets about 75% of three-phase power and starting torque is approximately 30% of the rated torque at the three phase.
The system in Switzerland is the same as in Sweden.
I know that the motor was mounted on a steam cleaner before. I will try to decipher the Nameplate. From the seller it got these informations: 220V, 1PS, 1425U/min

Single phase 240 is two Line Voltage wires and a ground.
Follow my instructions and you'll be fine.
btw, I am a licensed electrician and I work with motors regularly.
