Do not attempt to perform any of these tasks yourself. Performing these
tasks incorrectly could result in severe injury or death.
WARNING
!
Note: Most complaints regarding continual slow flow rate from the dispenser are caused by clogged
filters.
Only ASC/CSC only can perform this
task.

1 Trip the valve.
2 Authorize the hose at the console, if required.
3 Lift the operating handle.
4 Place the discharge nozzle in an approved container.
5 Squeeze the nozzle operating lever

defective and must be serviced or replaced.

7 Open and close valve with a wrench several times.
8 Place valve back in service.
Note: If repair is required, call an ASC/CSC to make the repairs.
If you are not sure which device is the shear valve or have not been
trained regarding its use or service, have the ASC/CSC inspect and
lubricate this device for you.
CAUTION
Do not attempt to make these repairs yourself. Doing so could result in
severe injury or death.
