Pressure Relief Procedure
SKIN INJECTION HAZARD
The system pressure must be manually relieved to
prevent the system from starting or spraying 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,
•
check or service any of the system equipment,
•
or install or clean the spray tip.
1. Engage the gun safety latch.
2. Shut off the hydraulic power supply.
3. Close the supply line shutoff valve, and then the
return line shutoff valve.
4. Disengage the gun safety latch.
5. Hold a metal part of the gun firmly to the side of a
grounded metal pail, and trigger the gun to relieve
pressure.
6. Engage the gun safety latch.
7. Open the drain valve (required in your system), and
have a container ready to catch drainage.
8. Leave the drain valve open until you are ready to
spray again.
If you suspect that the spray gun or hose is completely
clogged or that pressure has not been fully relieved after
following the steps above, very slowly loosen the hose
end coupling and relieve pressure gradually, then loosen
completely, then clear the valve or hose.
