Air Compressor break in

[cloud71]

Hello, OK figured out the impact problem, now trying to figure out compressor problem errr.

Here goes, OK the air compressor is new, its the kobalt 155psi 30 gallon at Lowes, I did a proper break in, and waited another 30mins of use give or take before changing oil.

After changing oil I looked at the dirty oil and it has metal shavings in it, here's a pic

The black pieces are the metal shaving's , is this normal?

Not sure, it seems those are more like machining chips. Wear from initial start-up would be more like small particles. The 13 year old Chinese girl must not have cleaned yours out so good is my thought.

Lol, gotta love Chinese stuff,, seems to be running OK but I don't wanna keep it if this is not good,, as I got 2 more weeks to take IG back to Lowes

Just a thought. Give it another week, change the oil again and see if there are any more metal shavings. That way if there are, you can still take it back

Yea I was thkin that, it doesn't seem to be running bad, it has gotten a little louder maybe, with some hissing sounds give or take.

Another thing is after break in it shut off at 155 psi once, then after that I had to adjust it to get to 155, also now after it shuts off at 155 it will go down to between 150-145,

As the air cools down, it takes less volume, so pressure drops. I assume the drop is not instant, but is over few minutes or so? I would blame cooling.

Sometime it will go go down 10 psi but not all the time, 2 days ago it shut off and only went down 5 give or take but is now reading 155, I didn't thk it would drop 10psi.

And sometimes it does take over night

use some soapy water and spray around the fittings...you got a leak maybe.

I've been chasing down leaks in my system for 3 months. Hope you have better luck than me!

really soapy water in a spray bottle..let it set for a few minutes you will see --foam for real small leaks and bubbles for massive ones.

Also I never have my compressor set above 130 PSI..not really needed.
compressor is at 130psi and my regulator for tools set around 100psi

BTW

Cloud71----what fixed your impact troubles ?

For most all single stage compressors, I agree with you on the max PSI.
However, my 2-stage Champion is factory set to on at 140 and off at 175. Of course I regulate it to abot 100PSI.
Although I do have a straight tap for those bolts that just don't want to move.

Try finding and pricing seperators and regulators rated for over 150PSI.

Yep I did that, all fitting are good, I tho it maybe either be check valve or unloader valve, it doesn't drain all the time after a fill the last time it never went down at all.

Nothing yet, I'm going to re grease it, with. Super tech multi duty high temp grease, last I used green synthetic ball joint grease.

See if that helps the wrench work like it should, if not I'm just going to buy another impact
