Pressure Relief Procedure

332234B

EN ti20999a

System pressure must be manually relieved to prevent it from starting or spraying accidentally. Fluid under high pressure can be injected into the skin and cause serious injury. To reduce risk of injury from injection, follow this procedure whenever you are instructed to relieve pressure, stop spraying, service equipment or install or clean spray tip. Read warnings, in operation manual.

1.

Set pump valve OFF. Turn engine OFF.

2.

Turn pressure to lowest setting. Trigger gun into pail to relieve pressure.

3.

Rotate handle counter-clockwise to open prime valve.

If you suspect that the spray tip or hose is completely clogged, or that pressure has not been fully relieved after following the steps above, VERY SLOWLY, loosen tip guard retaining nut or hose end coupling to relieve pressure gradually, then loosen completely. Then clean tip and hose.
