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 serious injury. To reduce the risk of an injury from injection, splashing fluid, or moving parts, follow the Pressure Relief Procedure whenever you:

D are instructed to relieve the pressure, D stop spraying,

D check or service any of the system equipment,

Dinstall or clean the spray tip.

1.Engage the gun safety latch.

2.Open the bypass valve.

3.Turn the ignition key to OFF.
