. 2. Turn off the bleed-type master air valve
(D).
3. Unlock the gun trigger.
4. Hold a metal part of the gun firmly to a grounded
metal waste container. Trigger the gun to relieve
fluid pressure.
5. Lock the gun trigger.
6. If you suspect that pressure has not been fully
relieved after following the steps above, check the
following:
a. The spray tip may be completely clogged. Very
slowly loosen the air cap retaining ring to
relieve pressure in the cavity between the
ball/seat shutoff and the plugged tip. Clear the
tip orifice.
b. The gun fluid filter or the fluid hose may be
completely clogged. Very slowly loosen the
hose end coupling at the gun and relieve
pressure gradually. Then loosen completely to
clear the obstruction.
c. After following the steps above, if the spray tip
or hose still seems completely clogged, very
slowly loosen the tip guard retaining nut or
hose end coupling and relieve pressure
gradually, then loosen completely. With tip
removed, trigger gun into waste container.
