High pitch noise 36mm hose
« on: June 29, 2017, 01:04 PM »
Just spoke with a rep, he tried telling me my hose or bag was clogged, which would be impossible, unless they came from factory. Vacuum and hose are new out of box. He also told me , I was first to complain about this problem? The noise is so high pitched, it actually hurts your ears. Any feed back would be appreciated.

Thank you,
Jason Medley

I would agree with him, it sounds like something is stuck in the hose.  Can you straighten it out and peer through it?

Try a broom handle.  Clog, if there is any, might be deep.

If you unhook the hose from the vac, does the noise persist? Trying to isolate noise to either vac or hose.

If noise is isolated to the hose, an obstruction is a possibility. I clear obstacles from the hose be dropping a 3/8" by 24" steel rod down through the hose. The rod has enough weight to clear obstacles.

Another hose possibility would be an air leak. A crack in the hose could whistle as you describe.

A pinball usually does the trick nicely for me, if not I just drop in more of them ;)

For my smallest sanders (Metabo SXE 400 Random & Bosch Delta) I use a small 19mm hose which is a more convenient push fit onto the tools and on the other end into the end of a 36mm Festo/ol hose.  It's also conveniently the right size & flexibility for clearing the flueways of my woodstove, whereas a 27mm hose is just too fat.

At high suction levels, the setup screams like a gas turbine jet engine such as fitted to a helicopter or small private jet or turboprop aircraft.  It too is somewhat beyond the threshold of pain.  My solution is to back off the suction until the noise disappears, which fortunately corresponds to an appropriate level of suction for the 6mm holes on the baby sanders' heads.

I too recommend the broomstick approach for clearing blockages, as a wooden dowel is quite easily manipulated, even when fully immersed in the hose, to remove recalcitrant blockages. I also recommend the exercise of caution here, as I've inadvertently punctured a couple of hoses with lodged nails and injudicious use of the dowel rod.
