I have a Dewalt 421 that I have had for like 12 or 15 years and it has been a good little sander.
I did replace the pad and that made all the difference in the world, it sanded so much better.
But it is a old sander and just was not picking up the dust in the bag like it used to but well I under stood that, it was old.
Well I put a new filter on my little shot air compressor and wanted to try it out, the sander was handy so I pick it up and started blowing it out.
WOW, I could not believe how much dust came out of it, from the top around the brushes and then when I hit the exhaust port it fogged the shop and just kept coming out with more and more every time I hit it with the air. After about 10 shots with 120 psi of air in the exhaust port I started blowing air back though the exhaust for the bag and more dust came out.
After I got all the dust out I then gave it a try and I could not believe how much better it picked up the dust and just generally sanded so much better then it had in the past.
So I guess what I am saying is, it may be time to blow the old sander out, you just may be really surprised how much better it sands.
