I have a 1HP HF dust collector hooked directly to my 3HP unisaw. Its not collecting dust very well. Whenever I make a cut there is lots of dust on the front of my shirt and pants. The bag fills up from time to time (have not been using the shop much lately) but I wonder what I should be looking for

Holes/air leeks in the saw
Perhaps the DC is just junk and needs an upgrade
Blade Plate may be to narrow
adding in over the blade dust collection

Im sure that I am not the only one who has had this issue. Please share how you have addressed it and what you have discovered.

Picture would help. Chips on your shirt are from the top side of the blade. You will need an over arm guard with chip collection to reduce that.

Yep, you won’t catch the dust the blade gullets carry out on to the top of the table without an over arm guard/dust pickup. I also suspect you are expecting more than such a small DC can deliver (speculation on my part). Effective DC requires moving huge amounts of air, and you may just need something with more arse.

I had decreased airflow due to a clog in the piping. Some chips jammed up in an elbow.

The bag could be plugged without being full of sawdust if it was ever used with really fine dust.

Has this collector ever done a good job?
Or, was it not adequate from the start?

I have one of the HF 1HP collectors and all I use it for is my router.
The HF 2 HP does a fine job on my table saw, jointer, band saw, etc.

Couldn’t hurt to wash the bag.
Depending on whether it is blinded (the term for a bag filter that is plugged) or not.
It might shrink. Put a spacer in the part that connects to the fan to prevent that.
