To do this, you must open the drawer of the device and check if there are any broken sheets Once located, all you have to do is push it back to its initial position.

It lowers itself

The reason for this problem is that the dustpan does not perform its function properlyi.e. it does not hold the belt properly. To fix it, you have to remove the wall-mounted dustpan, in the case of folding models you have to open it.

At this point you should check whether the tape that passes through a slit in the dustpan has something that hinders itIf this is the case, you can try to rectify this mistake and make this small tab stick to the area where the tape passes through.

However, you must be very careful not to close it all the way so that the tape has enough space to move around.

Breakage of slats

This tends to happen in areas where it hails quite frequently. In this case, sorry to say, there is no other option than to replace damaged sheets for new ones in perfect condition.

Breakage of the roller shutter motor
