The jet direction of the nozzles can be adjusted using the special device HAZET 4850-1 or with a needle. The jet of washing liquid from the nozzle must reach the upper edge of the glass cleaning zone of the windshield wiper blades. The rear window washer nozzle on the lever axis can be adjusted with a screwdriver (see illustration 40.0).
