3.4 The FXG2 Tornado Gun must be inspected in conjunction with the
40K Remote Control Valve. With the nozzles removed from the nozzle
head, the system water should be turned on and both triggers of the
Tornado Gun should be squeezed and released. The 40K Remote Control
Valve should be checked for air leaks, and checked to make sure that the
Control Valve opens and closes correctly. If the Control Valve or the FXG2
Tornado Gun is not operating correctly, determine and correct the cause
before putting the FXG2 Tornado Gun into service.
PREVIOUSLY USED TORNADO GUN
Do not use a Tornado Gun that has not had the following
procedures and inspection previously performed on it.
The following cleaning and inspections must be performed on the gun
before the start of each working shift:
3.5 Inspect all components. The air and water hoses should be secure
and free of cracks, splits, or holes. Both triggers should move smoothly
and return positively to the trigger’s fully open position when released. If
the trigger action is not smooth and positive, determine and correct the
cause before putting the gun into service.
3.6 Inlet connection fitting and nozzle should be tight and in good condi-
tion. The hose support burst shield must be installed at the rear of the
gun at the water inlet connection.
3.7 Check the 40K Remote Control Valve’s operation in conjunction with
the Jetstream Tornado Gun. With the nozzles removed from the nozzle
head, the system water should be turned on and both triggers of the
Tornado Gun should be squeezed and released to confirm that water is
exiting the nozzle head and is being controlled by the valve. The 40K Re-
mote Control Valve should be checked for air leaks and checked to make
sure that the dump valve opens and closes correctly. If the Control Valve
is not operating correctly, determine and correct the cause before putting
the 40K Remote Control Valve into service.
