6 . For D55170 and D55180 Only: Rotate manual lock on pilot valve
to a perpendicular position so pump will charge tanks.
7 . Allow compressor to pump up to "cut out" pressure.
N O T E : For constant run operation or units: after the compressor
reaches cut-out pressure the unit will continue to run but will not charge
a i r. A slight air noise may be heard which is the unloading of the air
through the pump head. For Stop/Start units: after the compressor
reaches cut-out pressure the unit will turn off and a slight air noise will
be heard which is the unloading of the head through the pressure
switch. If unit does not stop, refer to the Dual Control section in the
Common Procedures section.
N O T E : If any unusual noise or vibration is noticed, stop the
compressor and refer to the troubleshooting section.
8 . Attach hose and accessory.
9 . Adjust regulator to desired setting.

N O T E : If finished using compressor, follow steps 2 - 7 below.
2 . Unplug cord from wall outlet.
3 . Turn regulator knob counterclockwise until fully closed. Ensure
regulated pressure gage reads 0 PSI.
4 . Remove hose and accessory.
5 . Drain the air tank(s).
6 . Allow the compressor to cool down.

* To check for air leaks apply a solution of soapy water around joints.
While compressor is pumping to pressure and after pressure cuts out
look for air bubbles.
** The pump oil must be changed after the first 20 hours of operation.
