      If your SGS Air Compressor motor is unable to run, running slowly, or getting hot, it could be due to several reasons: * A fault in the line or insufficient voltage. * A power wire that is too thin or too long. * A fault in the pressure switch. * A fault in the motor itself. * Sticking of the main compressor. To resolve these issues: 1. Check the power line. 2. Replace the power wire. 3. Repair or replace the pressure switch. 4. Repair or replace the motor. 5. Check and repair the main compressor.

    Why is the pressure insufficient in my SGS Air Compressor, or why has the discharge capacity decreased?
    • M
      Mrs. Jessica WeaverAug 16, 2025
      If your SGS Air Compressor's pressure is insufficient or its discharge capacity has decreased, several factors could be responsible: * The motor might be running too slowly. * The air filter could be clogged. * There might be a leakage in the safety valve or discharge pipe. * The sealing gasket could be damaged. * The valve plate might be damaged, stuck, or have carbon buildup. * The piston ring and cylinder could be worn or damaged. To address these issues: 1. Check and fix the motor's speed. 2. Clean or replace the air filter cartridge. 3. Inspect and adjust the safety valve. 4. Examine and repair the discharge pipe. 5. Check and replace the sealing gasket. 6. Replace the valve plate and clean any carbon buildup. 7. Repair or replace the piston ring and cylinder.

    Why is my SGS Air Compressor using excessive oil?
    • E
      Elizabeth TuckerAug 22, 2025
      Excessive oil consumption in your SGS Air Compressor can be attributed to: * An oil level that is too high. * A breather pipe that is clogged. * A worn or damaged piston ring and cylinder. To address this: 1. Maintain the oil level within the specified range. 2. Inspect and clean the breather pipe. 3. Repair or replace the piston ring and cylinder.

    What causes the main compressor of my SGS Air Compressor to stick?
    • J
      John BanksAug 28, 2025
      If the main compressor of your SGS Air Compressor is sticking, it could be due to: * Moving parts burnt due to insufficient oil. * Moving parts damaged or stuck by a foreign body. Check the crankshaft, bearing, connecting rod, piston, piston ring, etc., and replace if necessary.
