What to do if my Porter-Cable Air Compressor has low discharge pressure?

If your Porter-Cable Air Compressor has low discharge pressure, it could be due to several reasons. Air leaks may be present, so tighten or replace any leaking fittings or connections, being careful not to overtighten. Another possible cause is restricted air intake; in this case, clean or replace the air filter element(s).
