  If your Porter-Cable Air Compressor isn't supplying enough air, this could be due to prolonged excessive air use, meaning the compressor might not be large enough for your needs. First, try decreasing air usage. Check the air requirements of your accessories; if they exceed what your compressor provides, you'll need a larger compressor. Also, inspect the hose for holes and replace it if necessary. Clean or replace the check valve if it's restricted, and tighten any loose fittings to prevent air leaks.

  If your Porter-Cable Air Compressor has air leaks in the air tank, at the air tank welds, between the head and valve plate, or from the safety valve, the air tank must be replaced. Do not attempt to repair the leak, drill into, weld, or modify the air tank, as this can weaken it and cause it to rupture or explode. Contact a Trained Service Technician. Operate safety valve manually by pulling on ring. If valve still leaks, it should be replaced.

  If the safety valve on your Porter-Cable Air Compressor pops off due to excessive tank pressure, it may be because the pressure switch isn't shutting off the motor when the compressor reaches its cut-out pressure, or the pressure switch cut-out is set too high. Set the On/Off switch to OFF (O). If the unit still doesn't shut off, contact a Trained Service Technician.

  It's normal for some pressure drop to occur on the regulated pressure gauge of your Porter-Cable Air Compressor when an accessory is in use.
