• Slow air pressure build-up

• Difficulty maintaining the required air pressure

• Air leaks around compressor connections

• Excessive oil carryover into the air system

• Unusual compressor noise or vibration

• Low-air-pressure warnings related to insufficient air supply

These symptoms may have other causes and should be confirmed through proper diagnostics.
