How do you break in a Mcgraw air compressor?

The break-in of a McGraw air compressor can be done by first turning the power switch off and unplugging the power cord. Fully open the regulator and drain valve before plugging the power cord in and turning the power switch on. You should then let the compressor run for 15 minutes and air will expel freely through the drain valve. After the 15 minutes have passed, you can turn the compressor off, unplug the power cord and close the drain valve.
