Irrigation system
A watering system with 255 litre tank can be installed to the rotary broom. The watering system reduces the amount of
sand dust, improves the cleaning outcome, lubricates the bristles, and decreases wearing off the bristles. Water is
sprayed to the area to be swept through the nozzles demonstrated on the pictures (picture 7). Detergents can be added
to the water to intensify the controlling of the amount of sand dust. The tank can be opened and closed from the faucet
behind the tank (picture 8). The faucet next to the pump (picture 9) can be used for, e.g., putting extra detergent back to
its container.
If the watering system is not used in a long time, empty the tanks, either by spraying or opening the faucet circled in
picture 9.
USING SALT WATER IS FORBIDDEN
