9.4.3 Disc brush, setting the sweeping
pattern
To ensure an efficient sweeping pattern, it is
necessary to set the disc brushes so they are
at a certain angle to the sweeping surface. This
ensures that the bristles only come into contact with
the sweeping surface for a fraction of the sweeping
circle. The brush should be calibrated in accordance
with the diagram shown.
 Left brush (1)
