Hi, first time posting anything. I have a scroll saw that just recently is giving me a problem. The hose that blows the dust away near the blade stopped working. I took out the bellows thinking it was that but its perfectly fine. No pin holes or tears. Nothing. the hose itself is also fine. When I put it back in place, it works a few hours but then stops again. I do the same routine as stated earlier and it works again for a few more hours. However, this time it appears to stop working all together. Still no rips, tears, holes or cracks. Any suggestions besides buy a new bellows would be appreciated.
Thanks Cindy
