Now you can adjust the sprinkler jet angle by changing the spacing of
the radius limiters. Spread them slightly so that you can turn them more
easily.
Position the limiters so that the metal bracket works between the two
limiters and the sprinkler faces in the desired direction. The further apart
the limiters are, the wider the range covered by the sprinkler. During
operation, the sprinkler head can independently move back and forth
between the limiters.
Now turn on the water. The device is ready to use.
Adjusting the jet of water:
Use the adjustment screw to adjust the jet of water as follows:
Turn the screw out – "direct" jet of water / turn the screw in – "wide"
jet of water.
If additional changes are required, repeat the preceding steps
correspondingly.
Attention: In order to maintain sensor functionality, regularly
clean the lens using a damp, lint-free cloth.
Do not leave the device outside when there is a risk of frost.
Please remove the batteries prior to storing the device.
