  • Air Filter Replacement: The air filter plays a critical role in protecting the engine from dirt and debris. Clean or replace the filter as needed to maintain optimal performance.
  • Check for Leaks: Periodically inspect the machine for oil or fuel leaks. Tighten connections and replace worn seals to prevent further leakage.
  • Service the Compressor: Regularly check the compressor airend and replace any worn parts such as seals, bearings, and gaskets. Clean the cooling system to prevent overheating.
  • Battery and Electrical Check: Ensure that the battery terminals are clean and secure. Inspect wiring and connections for any signs of wear or corrosion.
  • Pressure and Temperature Monitoring: Regularly monitor the pressure gauges and temperature indicators to ensure that the compressor is operating within optimal parameters.
4. Troubleshooting
If the Sullair 185 is not performing as expected, consider the following troubleshooting tips:
  • Low Air Pressure: If you're experiencing low air pressure, check for blockages in the intake filter or air supply hose. Also, verify that the compressor is operating at full speed.
  • Hard Starting or Stalling: If the engine is difficult to start or stalls frequently, check the fuel system for clogs or contamination. Make sure the fuel lines are free of debris, and ensure the battery is charged.
  • Overheating: If the compressor is overheating, ensure the cooling system is clean and functioning properly. Check the coolant levels and replace the coolant if needed.
  • Excessive Vibration or Noise: Unusual vibrations or noises might indicate that internal parts are worn out or misaligned. A professional inspection is recommended if you notice these symptoms.
