Pressure Relief Procedure
Pressure Relief Procedure
Follow the Pressure Relief Procedure
whenever you see this symbol.
This equipment stays pressurized until pressure
is manually relieved. To help prevent serious
injury from pressurized fluid, such as skin injection,
splashing fluid and moving parts, follow the
Pressure Relief Procedure when you stop spraying
and before cleaning, checking, or servicing
equipment.
Heated fluid can cause severe burns and can
cause equipment surfaces to become very
hot. Wear protective gloves and clothing when
operating this equipment in a heated system. Allow
the equipment to cool thoroughly before servicing.
1. Lock the gun/valve trigger safety.
2. Close all air bleed valves (required in your
system) to shut off the air supply to the pump.
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 pump bleeder valve (required in your
system), having a container ready to catch the
drainage.
7. Leave the pump bleeder 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 retaining nut or hose end
coupling and relieve pressure gradually, then loosen
completely. Now clear the tip/nozzle or hose.
