Hello,

I have bought a new base plate for my sander because the discs kept
falling off the old one. I cannot get the old plate off. The
instruction booklet says to unscrew the screw in the centre of the
plate with the allen key provided. Is there not a spindle lock, like
you find on an angle grinder?

This is the first time I have tried to remove the base plate and the
screw was stuck rigid to begin with. I finally managed to loosen it
but I wonder if it is cross threaded? It turns without getting any
looser and clicks as it turns around.

Is there any cure for this or will I have to send it back to Bosch?

Thanks.

You need to hold the base plate firm against the sander. It has lugs
that stop it slipping.

BTW I have discovered that scrubbing a clogged plate with a scrubbing
brush does restore the grip to some extent. I think they get clogged
with fine dust.
