What to do if my Blue Hawk 0300812 has low pressure?

  Erica WongAug 2, 2025
  If you're experiencing low pressure, not enough air, or the compressor doesn't stop with your Blue Hawk Air Compressor, several factors could be at play. Ensure the tank drain valve is closed. Check for leaks using soapy water and tighten or reseal any leaking connections, but avoid overtightening. Reduce air usage if it's excessive. Verify that the compressor is adequately sized for your accessories; if the air requirement of the accessory is higher than the CFM and the pressure supplied by the compressor, you need a larger compressor. Inspect the air hose for holes and replace if necessary. Finally, if the tank leaks, immediately replace it and do not attempt to repair.

What to do if the pressure drops when using my Blue Hawk 0300812 Air Compressor?

  If the regulated pressure gauge reading drops when the air accessory is being used with your Blue Hawk Air Compressor, adjust the regulator while the accessory is in use. Also, check the air requirement of the accessory. If it is higher than the CFM and the pressure supplied by the compressor, you need a larger compressor.

Why does the pressure relief valve open on my Blue Hawk Air Compressor?
- M

  If the pressure relief valve opens on your Blue Hawk Air Compressor, it's likely because the tank pressure exceeds the normal rating pressure or the pressure switch is stuck. In either case, the suggested solution is to replace the pressure switch.

  If air leaks from the regulator or the regulator does not regulate air pressure on your Blue Hawk Air Compressor, it is possible that the internal parts of the regulator are either dirty or damaged. Consider replacing the regulator or its internal parts.

Why won't my Blue Hawk Air Compressor motor run?
- O
  ortizmarieNov 13, 2025
  If your Blue Hawk Air Compressor's motor won't run, it could be due to several reasons. First, the tank pressure might exceed the preset pressure switch limit; the motor will start automatically when the tank pressure drops below the tank cut-in pressure. A blown fuse or tripped circuit breaker could also be the culprit; replace the fuse or reset the breaker, ensuring you're not using a higher-rated one. Also, check for low voltage and proper extension cord size, and try operating the compressor on a dedicated circuit. The check valve might be stuck; try removing and cleaning or replacing it. Ensure the cord has the correct wire gauge and the extension cord isn't excessively long. If the motor’s thermal overload protection has tripped, turn the air compressor off, unplug the power cord and...
