I have this wood polisher a Bosch PSS240A. Issue is the the polishing sheet cannot stick at the front, even after locking it.
Each time I'm starting to polish wood, the sheet is ok as you can see
But after a few seconds of polishing , the sheet is out as the clipping cannot hold the sheet
How come? Is there anything I can do to fix it quickly without needing to go to a repairshop?
