Operation
Pressure Relief Procedure
WARNING
SKIN INJECTION HAZARD
The system pressure must be manually relieved to prevent the system from
starting or spraying accidentally. Fluid under high pressure can be injected through the skin and cause a serious injury. To reduce the risk of an injury from injection, splashing fluid, or mov- ing parts, follow the Pressure Relief Procedure whenever you:
Dare instructed to relieve the pressure,
Dstop dispensing,
Dcheck or service any of the system equipment,
Dor install or clean the nozzle.
1.Fully release the gun trigger and lock the gun trigger safety by rotating the safety forward. See Fig. 1.
2.Shut off the fluid supply pump.
3.Hold a metal part of the gun firmly to the side of a grounded metal waste container. Unlock the gun trigger safety by rotating the safety backward. See Fig. 2. Trigger the gun to relieve fluid pressure.
4.Fully release the gun trigger and lock the gun trigger safety by rotating the safety forward.
5.Open the pump drain valve to help relieve fluid pressure in the pump, 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 open until you are ready to dispense again.
7.If you think that the gun nozzle or fluid hose is completely 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. Clear the nozzle or hose obstruction.
Gun Trigger Safety
WARNING
SKIN INJECTION HAZARD
To prevent accidental triggering of the gun and reduce the risk of a serious
injury, including fluid injection or splash- ing in the eyes or on skin, lock the gun trigger safety when you stop dispensing.
To lock the gun safety, release the trigger and rotate the safety toward the trigger as shown in Fig. 1.
NOTE: Do not try to force the trigger valve open with the safety engaged. This could result in component failure.
