See Pressure Relief Procedure on page 6.
PROBLEM CAUSE SOLUTION
Compressor does not start
Trapped air pressure Relieve air pressure by connecting air hose and
opening gun air valve.
Improper power supply Connect to power supply rated for your sprayer.
Tripped thermal overload in motor Check extension cord. Allow unit to cool down and
try again.
See Grounding and Electrical Requirements on
page 7.
NOTE: Remove extension cord and plug unit di-
rectly into outlet. If unit operates correctly, this indi-
cates an extension cord problem.
Clean filter, air cooler and cooling fan. Allow unit to
cool down and try again.
Have motor serviced.
No material output from pot. Pot is empty Refill pot. NOTE: Plate (45) shuts off material flow
to prevent air from entering hose.

the pot to maximum. Turn regulator clockwise to in-
crease.

Turn off the fluid supply valve. Relieve fluid pres-
sure from the hose. Remove gun from material
hose and slowly open fluid valve.

cycling material through the hose with the gun re-
moved.
Hose plugged or too long Relieve pressure. Clean hose or reduce hose
length.
