    Now that you are prepared, follow these steps to check the oil level through the sight glass.

    1. Clean the sight glass with a cloth to remove any dirt or condensation.

    2. Use a flashlight to illuminate the sight glass for a clearer view.

    3. Observe the oil level in the sight glass. It should be within the marked range.

    Oil Level Status Action Required
    Below Minimum Add oil immediately
    Within Range No action needed
    Above Maximum Drain excess oil

    Adding Oil to Maintain Compressor Performance

    Maintaining the proper oil level in your air compressor is crucial for optimal performance and longevity. This section will guide you through the process of adding oil using the sight glass, ensuring your compressor runs smoothly and efficiently. Understanding this simple task can help prevent potential damage and costly repairs.

    If the oil level is below the minimum mark, you must add oil. Selecting the correct oil type is crucial for the compressor’s performance. Always refer to the manufacturer’s specifications for the appropriate oil.

    1. Select the proper oil based on the manufacturer’s recommendations.

    2. Remove the oil fill cap located near the sight glass.
