Operation
Pressure Relief Procedure
INJECTION HAZARD
To reduce the risk of serious bodily
injury, including fluid injection, injury from
moving parts, or splashing in the eyes or
on the skin, always follow this procedure whenever
you shut off the pump, when checking or servicing
any part of the system, when installing or changing
dispensing devices, and whenever you stop dis-
pensing.
WARNING
1.
Close the pump air regulator.
2.
Close the pump’s bleed-type master air valve
(required in the system).
3.
Hold a metal part of the gun or valve firmly to a
grounded metal waste container and trigger to
relieve the fluid pressure.
If you suspect that the dispensing valve is clogged, or
that pressure has not been fully relieved after following
the steps above, very slowly loosen the dispensing
valve coupler or hose end coupling to relieve pressure
gradually, then loosen completely. Then clear the clog.
