CAP60P-OF no pressure & whistling sound
by Ric Hall
CAP60P-OF all of a sudden lost pressure after running.
It will usually hold pressure for a day or so before the pressure bleeds off.
This morning it bled off in a few minutes. Then later I turned it on just to nail a few small brads. I was able to do this, but pressure never went over 70 psi.
There was a high pitched whistling noise. this noise was also made each time I turned the compressor crank by hand.
