Side brushes
Side brush angle
The correct angle of the side brush is
approx. 5-8° towards the front and side,
it is setup at the factory and cannot be
altered.
Adjusting the side brush contact
It may be necessary to readjust the side
brush contact surface depending on the
wear of the bristles:

sweep/vacuum unit on/off (Fig. 20/4)
to lower the side brush and rotary
brush.
