4. Setup

4.1 Initial Break-in Procedure

Before initial use, it is recommended to perform a break-in procedure to properly seat the piston and ensure optimal performance:

1. Ensure the tank drain valve is fully open.
2. Plug the compressor into a suitable power outlet.
3. Turn the compressor ON.
4. Allow the compressor to run with the drain valve open for approximately 20 minutes. This allows the internal components to lubricate and seat correctly without building pressure.
5. After 20 minutes, turn the compressor OFF and unplug it.
6. Close the tank drain valve. The compressor is now ready for normal operation.

4.2 Placement and Electrical Connection

• Place the compressor on a stable, level surface in a well-ventilated area.
• Ensure the power switch is in the OFF position before plugging the unit into a standard 120V AC outlet.
• Avoid using excessively long extension cords, as this can lead to voltage drop and affect compressor performance. If an extension cord is necessary, use a heavy-duty, grounded cord rated for outdoor use.

5. Operating Instructions

5.1 Connecting Air Tools

To connect an air tool:

1. Ensure the compressor is OFF and unplugged.
2. Attach your air hose to the quick connect outlet.
3. Connect your air tool to the other end of the hose.

5.2 Powering On and Adjusting Pressure

1. Plug in the compressor and turn the power switch ON. The compressor will begin to build pressure.
2. Monitor the Tank PSI gauge to see the internal tank pressure.
3. Use the Pressure Regulator Dial to set the desired output pressure for your air tool. Turn the dial clockwise to increase pressure and counter-clockwise to decrease it.
4. Monitor the Regulator PSI gauge to confirm the set output pressure.

5.3 Using the Compressor

Once the desired pressure is set, you can operate your air tool. The compressor will cycle on and off automatically to maintain pressure in the tank.

6. Maintenance

6.1 Draining the Air Tank

Moisture accumulates in the air tank during operation. To prevent corrosion and ensure safe operation, drain the tank daily or after each use:

1. Turn the compressor OFF and unplug it.
2. Place a suitable container under the tank drain valve.
3. Slowly open the tank drain valve to release air and moisture.
4. Once all air and moisture have been expelled, close the drain valve.

6.2 General Cleaning

Keep the compressor clean and free of dust and debris. Use a dry cloth to wipe down the exterior. Do not use solvents or harsh chemicals.

7. Troubleshooting

If you encounter issues with your Makita AC001, refer to the following common problems and solutions:

• Compressor not supplying enough air: This can occur due to prolonged excessive air usage or if the compressor is not adequately sized for the air requirement of the accessory. Check the accessory's air requirement (SCFM or pressure) and ensure it does not exceed the compressor's capacity (0.58 CFM at 40 PSI, 0.45 CFM at 90 PSI). Consider reducing air usage or using a larger compressor for demanding tasks.
• Air leaks: Inspect all fittings, hoses, and connections for leaks. Tighten any loose connections. A soapy water solution can help identify small leaks.
• Compressor runs continuously or frequently: This may indicate an air leak in the system or a faulty pressure switch. Check for leaks first.
• Compressor does not start: Ensure the power cord is securely plugged in and the power switch is ON. Check for tripped circuit breakers.
