The changeover nozzle should be fitted to the
spray lance so that the marking line (5) is at the
top.
In this position, the two balls inside the changeo-
ver nozzle seal the two upper nozzles so that the
water jet always comes out at the lower nozzle.
The marking line always indicates the symbol of
the jet concerned. The type of jet is selected by
turning the nozzle guard (1) with the three nozzles
to the required position, with the hand gun clo-
sed.
