9. HYDRAULICS
The collecting sweeper can be connected to a 2-hose or a 4-hose hydraulic system. The device 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.
The collecting sweeper is attached to the base machine with 2 or 4 hoses. In a 2-hose system (figures 1 and 2), the flow
control valve is used to choose whether to rotate the brushes or open/close the bottom plate. In a 4-hose system (figures
3 and 4), both actions can be controlled by the base machine’s hydraulics and a separate valve is not needed.
The brush rotation speed is adjusted by the flow control valve. If the base machine has a flow control feature, the control
valve in the attachment can be set to position 10.
