Operation

1. Shut off the power to the pump.
2. Close the bleed-type master air valve (required
with air powered pumps).
3. Actuate the gun to relieve pressure.
4. Open the pump drain valve (required in your
system) to help relieve fluid pressure in the dis-
placement pump. Actuating the gun to relieve
pressure may not be sufficient. Have a container
ready to catch the drainage.
5. Leave the drain valve(s) open until you are ready
to spray again.
