Just bought the little angle grinder from Aldi. Got it home, took it out to have a play (the AG!) and it rattled. Didn't like the idea of something locking the motor during use so opened up the handle end. There was a spare screw for the case in there, but fortunately in a 'compartment' with no functional parts in it and no way to any other place. I did wonder if it was deleberate (as it was harmless) so RTFM. No mention so removed the screw. A spare button on a shirt is one thing but...!
