Makita M992 Belt Sander

[Bernie Summers]

My belt sander seems to get a blocked outlet, to the dust bag, very easily. It then throws dust mainly out the front of the belt. I pull the bag off & clean out the outlet & it goes fine for about 2 mins.
Anybody got any ideas on how to fix it?

Try giving the bag a good clean as it sounds like it is not 'breathing', just a thought.
