3. Power Connection
- Ensure the power switch on the compressor is in the 'OFF' position.
- Plug the compressor's power cord into a standard 120V AC grounded electrical outlet.
- Avoid using extension cords if possible. If an extension cord is necessary, use a heavy-duty, grounded cord rated for the compressor's power requirements.
Operating Instructions
1. Starting the Compressor
- With the power cord connected and the air hose attached, turn the power switch to the 'ON' position.
- The compressor will start to fill the air tank. Allow it to run until it reaches its maximum pressure (110 PSI) and automatically shuts off.
- The tank pressure gauge will indicate the pressure inside the tank.
2. Adjusting Output Pressure
- Use the large red regulator knob to adjust the desired output air pressure for your tool. Turn clockwise to increase pressure, counter-clockwise to decrease.
- Monitor the outlet pressure gauge to set the correct pressure. Refer to your air tool's manual for recommended operating pressures.
