5. Turn the Power Switch ON.

6. Allow the Air Compressor to build up pressure until it cycles off.
   Note : At the beginning of the day’s first use of the Air Compressor, check for air leaks by applying soapy water to connections while the Air Compressor is pumping and after pressure cut-out. Look for air bubbles. If air bubbles are present at connections, tighten connections. Do not use the Air Compressor unless all connections are air tight, the extra air leaking out will cause the compressor to operate too often, increasing wear on the compressor.
   Note : As long as the Power Switch is ON, the operation of the Air Compressor is automatic, controlled by an internal pressure switch. The Compressor will turn on automatically when the air pressure drops to 135 PSI, and will turn off automatically when the air pressure reaches 175 PSI.
   WARNING! TO PREVENT SERIOUS INJURY AND DEATH FROM EXPLOSION : Do not adjust the internal pressure switch. Any change to the automatic pressure levels may cause excess pressure to accumulate, causing a hazardous situation.

7. Adjust the Regulator Knob so that the air output is enough to properly power the tool, but the output will not exceed the tool’s maximum air pressure at any time. Turn the knob clockwise to increase the pressure and counter-clockwise to decrease pressure. Adjust the pressure gradually, while checking the air output gauge to set the pressure.

8. Make sure the air tool’s throttle or switch is in the off position. Connect the air tool to the air hose.

9. Open the in-line Shutoff Valve.

10. Use the air tool as needed.

11. After the job is complete, turn the Power Switch OFF.
