Pressure Relief Procedures

INJECTION HAZARD

The system pressure must be manually relieved to pre- vent 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:

•are instructed to relieve the pressure

•stop spraying

•check or service any of the system equipment

•install or clean the spray tip

FIRE AND EXPLOSION HAZARD

NOTE: If you suspect that the spray gun or hose is com- pletely 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 it completely. Then clear the valve or hose.
