Tools and materials

To replace the roller shutter belt winder, you only need one tool: a suitable screwdriver. Sensible because it also has to match the screws on the winder. Otherwise, there is a risk of unnecessary wear and tear. In our case, we need a PH2 screwdriver.

Remove the old belt winder.

First of all, the old belt winder has to be removed. But that’s pretty easy. When the housing is opened, you can see the more or less rolled-up belt inside. This is now carefully removed and unwound. It immediately shows where the problem was: The spring on the winder is broken.
