Question about Air Tools & Compressors
LOW AIR PRESSURE IN TANK
This is a fairly common problem in small pancake compressors. I would start by making sure no air is escaping from the condensation drain valve on the bottom of the tank.
Next Pump it up as much as it will hold and turn it off. Listen for air leaks around the fitting on the bottom of the regulator that screws into the tank. These really need teflon tape and to be screwed in well.
Next check the regulator itself. These are rather inexpensive and don't last long when the compressor is used a lot. Also it doesn't take much of a bang when jostled around.
Is the regulator for tank pressure set correctly? Thump the glass covering the dial with your finger. Sometimes it sticks and you'll think it's set correctly when it isn't.
Lastly, check each connection for tightness with teflon tape. If all looks good, gamble about $20 on a new regulator. Odds are that's where the problem lies. This has happened to me a few times.
