With the Turbo-Driven Pop-Up Sprinklers 200 and 380 the jet rotates backwards and forwards in a circle. The pop-up sprinkler rotates backwards and forwards with the same speed both with smaller sectors or angles, e.g. 90? and with larger sectors, e.g.360?.
To achieve a uniform sprinkling density on a lawn with several simultaneously operating pop-up sprinklers, the sprinklers with a large angle, e.g. 360? require nozzles with a greater output.
Reason: Within a given time, a pop-up sprinkler with the small angle e.g. 90? covers a square metre of lawn with its oscillating jet more often than one with a large angle.
Because of this, the pop-up sprinkler includes 4 nozzles with different water consumption. These should be adjusted according to the operating instructions or the packaging.
Technically, these pop-up sprinklers could sprinkle each sector with each of the 4 different nozzles.
T 380 nozzle adjustment: For this, the cover must be removed (central screw). Then the range adjustment mechanism is held with one hand and the nozzle selector disc is turned with the other hand until the required nozzle is in the range adjustment mechanism.
