3.3 Placement and Electrical Connection

• Place the compressor on a firm, level surface in a clean, well-ventilated area.
• Ensure the power switch is in the "OFF" position.
• Connect the power cord to a grounded 110V/60Hz electrical outlet. Do not use extension cords unless absolutely necessary, and if so, ensure it is rated for the compressor's power requirements.

4. Operating Instructions

4.1 Initial Start-Up

• Open the tank drain valve (located at the bottom of the tank) to ensure no pressure is present.
• Turn the power switch to the "ON" position. The compressor will start to build pressure.
• Allow the compressor to run until it reaches its maximum pressure and automatically shuts off. This may take approximately 81 seconds.
• Close the tank drain valve.

4.2 Connecting Air Tools

• Ensure the air tool is rated for the compressor's pressure output.
• Connect your air hose to the compressor's air outlet.
• Attach the air tool to the other end of the hose.
• Adjust the regulator knob to the desired operating pressure for your tool. The pressure gauge will display the current output pressure.

4.3 Shutting Down

• Turn the power switch to the "OFF" position.
• Disconnect the air hose and tools.
• Slowly open the tank drain valve to release all air pressure from the tank. This is crucial to prevent corrosion and ensure safety.
• Close the drain valve once all air has been released.

5. Maintenance

Regular maintenance ensures the longevity and safe operation of your air compressor. This oil-free unit requires minimal maintenance.

5.1 Daily Maintenance

• Drain Moisture from Tank: Open the tank drain valve after each use to release accumulated moisture. This prevents rust and corrosion inside the tank.
• Inspect for Leaks: Check all connections and hoses for air leaks. Tighten any loose fittings.

5.2 Weekly Maintenance

• Clean Air Filter: Inspect and clean the air filter as needed. A clogged filter can reduce efficiency.
• Check Fasteners: Ensure all nuts, bolts, and screws are tight.
