How do I use the portable compressor feature to inflate tires?

Screw the Sure Fit® nozzle onto the tire valve stem without overtightening. Press the Compressor Power Button, then use the "+" and "–" Pressure Control Buttons to set your desired pressure (3-120 PSI). Press the Compressor Power Button again to begin inflating. The compressor will automatically stop when the preset pressure is reached. Unscrew the nozzle and allow the unit to cool before storing. (Page 9)
