Yesterday when I powered up my Makita MAC2400 compressor, it free flowed through the regulator. After a bit of fooling with it, I finally took apart the regulator and observed the following.
There was a mix of yellow and black goo and some water in it. Some of the metal parts were rusted.
Cleaned it up as best I could, and put it all back together and turned it on. Freee flow through the regulator still.
Took it apart again and put some air tool oil on all the seals including the one on the plunger. Put it all back together again and turned it on. First time around, it worked fine, drained air and tried again, this time it free flowed, drained and tried again and this time it worked fine. Left it pressured up and unplugged over night. Tank pressure dropped from 140 psi to 130 psi which seemed pretty good.
So my question is, why might it be intermittent in either holding pressure, or free flowing?
Is there something different I should have done when cleaning / sealing the regulator.
