Pressure Relief Procedure
1. Set pump valve OFF. Turn engine OFF.
2. Turn pressure to lowest setting. Trigger gun into pail
to relieve pressure.
3. Open prime valve (vertical).
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.
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, page 2).
