1.

Shut off the power to the pump.

2.

Turn off the air and fluid supply to the gun.

3.

Close the bleed-type master air valve (required in 
the system).

4.

Trigger the gun into a grounded metal waste con-
tainer to relieve the fluid pressure.

5.

Open the pump drain valve (required in the system) 
to help relieve fluid pressure in the displacement 
pump. In addition, open the drain valve connected to 
the fluid pressure gauge (in a system with fluid regu-
lation) to help relieve fluid pressure in the hose and 
gun. Triggering the gun to relieve pressure may not 
be sufficient. Have a container ready to catch the 
drainage.

6.

Leave the drain valve(s) open until you are ready to 
spray again.

7.

If you suspect that the spray tip or hose is com-
pletely clogged or that pressure has not been fully 
relieved after following the steps above, very slowly 
loosen the hose end coupling and relieve pressure 
gradually, then loosen the coupling completely. Now 
clear the tip or hose obstruction.

Adjust the system control device, if it is automatic, so the 
gun starts spraying just before meeting the workpiece 
and stops as soon as the workpiece has passed. Keep 
the gun a consistent distance, 8 to 10 in. (200 to 250 
mm), from the surface of the object being sprayed.

To achieve best results when applying fluid:

•

Keep gun perpendicular and 8 to 10 inches (200 to 
250 mm) from object being sprayed.

•

Use smooth, parallel strokes across surface to be 
sprayed with 50% overlap. See F
