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 serious injury. To reduce the risk of an injury from injection, splashing fluid, or moving parts, follow the Pressure Relief Procedure whenever you:
Dare instructed to relieve the pressure,
Dstop spraying/dispensing,
Dcheck or service any of the system equipment,
Dor install or clean the spray tip/nozzle.
1.Lock the gun/valve trigger safety.
2.Close the pump air bleed valve (required in your system).
3.Shut off the main air bleed valve (required in your system).
4.Unlock the gun/valve trigger safety.
5.Hold a metal part of the gun/valve firmly to the side of a grounded metal pail, and trigger the gun/valve to relieve pressure.
6.Lock the gun/valve trigger safety.
7.Open the drain valve (required in your system) and/or the pump bleeder valve, having a container ready to catch the drainage.
8.Leave the drain valve open until you are ready to spray again.
If you suspect that the spray tip/nozzle or hose is completely clogged, or that pressure has not been fully relieved after following the steps above, very slowly loosen the tip guard retaining nut or hose end coupling and relieve pressure gradually, then loosen completely. Now clear the tip/nozzle or hose.
