Operation
Pressure Relief Procedure
1.
Shut off the fluid supply to the flow gun.
2.
Place a waste container beneath the nozzle to catch
the drainage.
3.
Actuate the flow gun. Wait until the fluid stops flow-
ing from the hose and gun.
4.
Shut off power to the fluid supply system.
If you suspect that the nozzle or hose is completely
clogged, or that pressure has not been fully relieved
after following the steps above, very slowly loosen the
nozzle or hose end coupling to relieve pressure gradu-
ally, then loosen completely. Now clear the nozzle or
hose.
Troubleshooting
The following table contains troubleshooting information.
The system pressure must be manually relieved to
prevent the system from starting or spraying
accidentally. Fluid under high pressure can be injected
through the skin and cause a serious injury. To reduce
the risk of an injury from injection, splashing fluid, or
moving parts, follow the
whenever you:
• are instructed to relieve the pressure,
• stop dispensing,
• check or service any of the system equipment,
• or install or clean the nozzle.
Problem
Cause(s)
Solution(s)
Gun fails to dispense or shut off
when actuator is tripped or
released.
Material lodged in nozzle.
Follow the
Pressure Relief
Procedure
(above). Clear nozzle of
blockage.
Fluid supply, hose, passages
clogged.
Check fluid supply settings, hoses,
etc. for proper material supply.
At initial set up, actuating hoses are
reversed.
Set up actuating hoses correctly by
reversing hoses.
Malfunction at actuator and
four-way valve.
Check actuator and four-way valve
for proper function.
Air supply inadequate; material
supply depleted.
Check air supply and material
supply.
Gun continues to fail when actuator
is tripped or released.
Seals and packings are worn.
Rebuild gun as necessary.
