I just bought one too. Don’t think it’s gonna last a month. Make similar noise. I’m losing what faith I had in HF.

Sorry, but you get what you pay for. HF is only for short time use, disposable tools. ( IME)

Sounds like there is something in the impeller or it is rubbing against the houseing.. Did you take a hose off and look….or open the housing.

Tomorrow I’ll take a peak inside.
The sound is intermittent & rhythmic.. Yes, I need to look inside, but I was thinking this is like a vibration thing… Like something’s off center and triggering some harmonics, on and off..

You could try swapping out the bearings who knows what quality they are.

DC noise?
Sounds like fun! Not.

I’ll play the guessing game:

+1 remove the hose adapter and look inside. Could be a odd shape debris stick inside.
Had something similar as a long splinter of bark would get stuck on the housing weld, then rub until it was spinning around again; and repeated for several minutes till it broke into smaller pieces and was ejected.

+1 Pull the large impeller cover (yes, one with ALL those screws).
- Inspect for debris.
- inspect for loose impeller.
- remove the impeller and check for damage, loose rivets on fins, or bent impeller.
- spin the impeller on end of large screw driver, or shaft of socket extension; does it wobble?
- check inside of the housing for any rubbing.
- Is the motor mount perpendicular (90°) to the housing?

- Double check the mounting bolts to the sheet metal base. Could be loose.

- Now run the motor without impeller.
: IF noise is gone, figure out how impeller is making the noise.
: If noise is still there, then you have motor vibration issue. Could be lose motor mount, could be bad motor bearings, or even a bent motor shaft due rough handling during shipping.

Let us know what you find, and if I won a prize! LOL

Best Luck.

If you’re within the time limit, dint mess with it, just return it.

For a few bucks more buy a Grizzly.

New machine? If so, DO NOT TAKE IT APART. RETURN IT!! Why should you need to repair a new tool?

I would at least pull off the impeller cover to check the clearance and hand turn the impeller to check for any rubbing before hauling it back to HF. It could be a very simple fix.

If only there dust collectors were as good as that purple spray gun. For 40$, best value in the store.

Have your say...
