4. Ensure the two professional silencers are securely attached to the motor's air intake ports.

3.2 Initial Checks

• Verify that the power switch is in the "OFF" position.
• Ensure the drain valve at the bottom of the tank is fully closed.
• Confirm that the pressure regulator knob is turned counter-clockwise to its lowest setting.

3.3 Connecting to Power

• Plug the compressor's power cord directly into a grounded 110V/60Hz electrical outlet. Avoid using extension cords if possible.

4. Operating Instructions

Familiarize yourself with the controls and operating procedures before using the compressor with air tools.

4.1 Starting the Compressor

1. Ensure all connections are secure and the drain valve is closed.
2. Flip the power switch to the "ON" position. The compressor will begin to fill the air tank.
3. Monitor the tank pressure gauge. The compressor will automatically shut off when it reaches its maximum pressure (approx. 115 PSI).

4.2 Adjusting Output Pressure

1. Connect your air tool to the quick-connect coupler.
2. Turn the pressure regulator knob clockwise to increase the output pressure to the desired setting for your tool. The output pressure will be displayed on the tool pressure gauge.
3. Turn the knob counter-clockwise to decrease the pressure.

4.3 Using Air Tools

• This compressor is suitable for staple guns, brad nail guns, roofing nail guns, framing nail guns, spray guns, blow guns, air drills, HVLP spray guns, and electrical automatic screwdrivers.
• Always refer to your air tool's manual for specific pressure requirements and operating instructions.

5. Maintenance

Proper maintenance ensures the longevity and optimal performance of your air compressor.

5.1 Draining the Air Tank

• Moisture accumulates in the air tank during operation. Drain the tank daily or after each use to prevent corrosion.
• Disconnect power and release all air pressure from the tank.
• Open the drain valve located at the bottom of the tank to release accumulated moisture. Close the valve once all moisture is drained.

5.2 Cleaning Air Filters

• Regularly inspect and clean the air filters to ensure optimal airflow and prevent motor strain. Refer to the included manual for specific cleaning instructions.

5.3 Oil-Free Design

• This compressor features an oil-free motor, eliminating the need for oil checks or changes. This contributes to environmental friendliness and reduced maintenance.

6. Troubleshooting

Refer to this section for common issues and their solutions.

6.1 Compressor Not Starting

• Check if the power cord is securely plugged into a live outlet.
• Ensure the power switch is in the "ON" position.
• Check for tripped circuit breakers or blown fuses.
• If the motor hums but does not start, the overload protector may have tripped. Disconnect power, wait a few minutes, and press the reset button (if available).

6.2 Low Air Pressure or Slow Recovery

• Verify the pressure regulator is set to the desired output pressure.
• Check for leaks in air hoses, fittings, or tool connections.
• Inspect air filters for clogging and clean or replace if necessary.
• Ensure the power supply is adequate and not experiencing voltage drops.

6.3 Excessive Noise or Vibration
