2. Placement: Place the compressor on a stable, level surface in a well-ventilated area. Ensure there is adequate space around the unit for air circulation.
3. Power Connection: Plug the power cord directly into a grounded 120 Volt AC electrical outlet. Avoid using extension cords if possible.
4. Connect Air Hose: Attach your air hose to the quick connect coupler. Ensure it is securely fastened.

6. Operating Instructions

1. Initial Start-Up: Before first use, ensure the drain valve is closed. Turn the pressure regulator knob counter-clockwise to the lowest setting.
2. Power On: Flip the On/Off switch to the 'On' position. The compressor will begin to fill the tank with air. It will automatically shut off once the maximum pressure (110 PSI) is reached.
3. Adjust Pressure: Connect your air tool to the air hose. While observing the regulated pressure gauge, slowly turn the pressure regulator knob clockwise to increase the output pressure to the desired PSI for your tool.
4. Operation: Use your air tool as needed. The compressor will cycle on and off automatically to maintain tank pressure.
5. Power Off: When finished, turn the On/Off switch to the 'Off' position. Disconnect the air tool.
6. Depressurize Tank: Open the drain valve to release all air pressure from the tank. This is important for safety and to prevent tank corrosion.

7. Maintenance

The McGraw air compressor features an oil-free pump, significantly reducing maintenance requirements. However, regular care is still essential for optimal performance and longevity.

• Drain Tank: Always drain the air tank after each use or daily. Open the drain valve at the bottom of the tank to release any accumulated moisture. This prevents rust and extends the life of the tank.
• Cleaning: Keep the compressor clean and free of dust and debris. Wipe down the exterior with a damp cloth. Do not use harsh chemicals or abrasive cleaners.
• Storage: Store the compressor in a clean, dry location. Utilize the cord wrap and hose retainer for tidy storage.
