Hi, I have a Roca W12 pantograph wiper system. Can I change the symetry of the movement so the wiper goes further right/left but keeping the parking position; I mean for example having 35 deg. on the left side but 45 deg on the right side.
Hi, due to the mechanical construction of the W12 gearbox, you can only have a symmetrical sweep from a centerline. You can have the centerline of the sweep off-center from the centerline of the window, but then the parking position will also change.
Is the wiper working ok before you started to change? It could be that the sweep angle plate is stuck to the plate behind if it has been operating for a while. Don't use more force by pulling the wiperarm. Try to loosen the angle plate gently with a screwdriver.

Thanks so much for your reply.
After loosening the screws I am unable to move the wiper. It does not move as easily as your demonstration. It won't move at all.

how to open
went through 3 of these in 2 years!! rubbish product. Now I will have to drill more holes to fit a proper wiper system on instead of these.
