Procedure Trigger Lock
Always engage trigger lock when you stop spraying to
prevent gun from being triggered accidentally by hand or
if dropped or bumped.
To engage trigger lock, release trigger and rotate lock
downward. See F
IG . 6.
To disengage trigger lock, rotate it upward. See F IG . 7.
1. Fully release gun trigger and engage gun trigger
lock. See F
IG . 6.
2. Shut off fluid supply pump.
3. Hold a metal part of gun firmly to side of a grounded
metal waste container. Disengage gun trigger lock.
See F
IG . 7. Trigger gun to relieve fluid pressure.
4. Fully release gun trigger and engage gun trigger
lock. See F
IG . 6.
5. Open pump drain valve to help relieve fluid pressure
in pump, hose, and gun. Triggering gun to relieve
pressure may not be sufficient. Have a container
ready to catch drainage.
6. Leave drain valve open until you are ready to dis-
pense again.
7. If you think the gun nozzle or fluid hose is completely
clogged or that pressure has not been fully relieved
after following the previous steps, very slowly loosen
hose end coupling and relieve pressure gradually,
then loosen coupling completely. Clear nozzle or
hose obstruction
Do not try to force trigger valve open with trigger
lock engaged. This could result in component fail-
ure.
