  • Page 50: Settings

    9.2. Settings For good sweeping results a correct setting of the following: • the suction mouth, • the brush angle, and • the brush pressure is essential. 9.2.1. Adjusting the suction mouth The degree of suction power is influenced by the setting of the suction mouth. The distance between the suction mouth and the road surface is determined by the guide wheel attached to the suction mouth.
  • Page 51 When the brushes are set a forward angle, the rear of the brush does not touch the surface. This brings the rubbish in front of the suction mouth so that it does not revolve with the brush. The sideways angle is adjusted to the shape of the surface or the degree of brush wear. Some vehicle models are equipped with a hydraulic sideways adjustment which can be operated from the cabin.

  • Page 52: Maintenance After Sweeping
