Pressure Relief Procedure
Follow this Pressure Relief Procedure whenever instructed
to relieve pressure, stop spraying, check or service equipment,
or install or clean spray tip.
1. Turn OFF power and turn sprayer pressure control to lowest pressure setting.
2. Hold gun against side of flushing pail. Trigger gun into pail
to relieve pressure.
If you suspect spray tip or hose is 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. Clear
hose or tip obstruction.
