My Porter Cable keeps hissing
My Pancake comp.(Porter Cable) keeps hissing and sounds like it wants to start up.
This happens after I run it for an hour or two.
It will start pressuring up then shut off, but when it shuts off it will start losing air slowly. ( a light hissing noise) Then it will start trying to start, but only for a second or two. This will continue until I shut it off.
I thought it just burned up or went out; but when I brought it home it had been off and unplugged for 5 or 6 hours(I also completely depressurized it). I plugged it in; it ran fine for an hour or two then started doing the same thing. Anyone have any answers or ideas anything will be appreciated
