I have a older electric B & D Leaf Blower/Vac. I was using it yesterday to pick up the leaves leftover from the fall. It has been a real pita to get the collection bag off the blower/vac. I thought I had this issue fixed. But apparently not. I pretty much have to tap the collection bag off the blower/vac each time.
So I used my 1/4 sheet sander and sanded the the tube where the collection bag slides on. Then applied some paste wax to it. Seems this did the trick. It works like a charm. This blower/vac is nice to have. It does a good job mulching the leaves up. It makes much easy putting the leaves into leave bags and saves on the amount of bags you use.
