Operation
Pressure Relief Procedure
WARNING
SKIN INJECTION HAZARD
The system pressure must be manually
relieved to prevent the system from
starting or spraying/dispensing acciden-
tally. 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/dispensing,
 check or service any of the system equipment,
 or install or clean the spray tip/nozzle.
1. Lock the gun/valve trigger safety.
2. Close the bleed-type master air valve (required in
your system).
3. Unlock the gun/valve trigger safety.
4. Hold a metal part of the gun/valve firmly to the side
of a grounded metal pail, and trigger the gun/valve
to relieve pressure.
5. Lock the gun/valve trigger safety.
6. Open the drain valve (required in your system),
having a container ready to catch the drainage.
7. Leave the drain valve open until you are ready to
spray/dispense again.
If you suspect that the spray tip/nozzle or hose is
completely clogged, or that pressure has not been fully
relieved after following the steps above, very slowly
loosen the tip guard retaining nut or hose end coupling
and relieve pressure gradually, then loosen completely.
Now clear the tip/nozzle or hose.
