To avoid cavitation, make sure that the pump output is higher than the water
outlet volume set on the nozzle.
The pump can cavitate through the discharge of too much extinguish-
ing agent.
Loose ground can be softened by rain or fire fighting water and can ef-
fect the stability.
Watch the extinguishing agent jet.
Reduce flow rate to prevent cavitation.
Change location if stability is insufficient.
The nozzle can be opened or closed via the bracket shift lever.
Slowly and in a controlled manner, push the bracket shift lever of the
nozzle into the rear position to open the nozzle.
Bracket shift lever points towards the broad side of the pictogram.

Pressure outlet of the nozzle is opened.
Slowly and in a controlled manner, push the bracket shift lever of the
nozzle into the forward position to close the nozzle.
Bracket shift lever points in direction of the pointed side of the pic-

togram.
Pressure outlet of the nozzle is closed.
Flow rate at a working pressure of 6 bar.
Adjust the flow rate adjustment to the desired flow rate.
