damaged, if situation speed is too high.
While moving the broom longer distances, lock the roll to upper position in order to avoid bouncing of the broom.

Sivu 13 / 20
7.7. 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.

9. HYDRAULICS
The rotary broom can be connected in two different ways, either with two (figure 1) or four (figure 2) hoses. When
connecting with two hoses, the hydraulics of the basic machine is connected to quick connectors and a separate switch
is used to choose whether the broom is rotated or turned. When connecting with four hoses, a rotation cylinder and the
rolling of the engine are connected separately to the hydraulics of the basic machine. This means that the lifting and
rotating of the broom can be done with the hydraulics of the basic machine, and no separate control valve is needed.
The rotation speed of the broom is adjusted with the valve shown on figure 1. The suitable position is usually found
between 5 and 8. If there is a flow controller in the basic machine, the speed control valve can be set to position 10.
The shock absorber cylinder, which is inside the chassis, must be air-free if it needs to be released, so the cylinder must
be moved to its maximum positions when it is attached to the system. If there is air left in the cylinder, the shock
absorption does not work, and the broom starts to “jump”. Also, a too slow a rotation speed of the broom causes the
broom to “jump”
The rotary broom is equipped with a complex closed hydraulic system, which has been tested and adjusted by the
manufacturer. Any repairs to the system are to be performed by replacing one component at a time by a professional in
hydraulics. Any alterations or modifications to the hydraulic system are on the sole responsibility of the client.
