Pressure Regulator Adjustment
Start the compressor and adjust the service valve to
maintain service air pressure approximately at 1 psi
over rated pressure. Turn the inlet valve regulator
adjusting screw until air just begins to escape from
the control air orifice (located at the bottom of the
regulator; refer to Figure 6-5). Lock the adjusting
screw in place with the locknut. The regulator is now
properly set.

Water Condensate Drain Maintenance
If your compressor is fitted with the standard solenoid
condensate drain valve, it is necessary to periodically
clean the strainer. Remove the knurled cap from the
strainer and remove the strainer screen. Clean the
screen and reinstall. If the screen is damaged, the
strainer assembly must be replaced (P/N 241772).
