Adjust parallel brush pattern
Check/adjust the brush pattern
– Coat a flat surface with chalk and move the
unit over the chalked area.
– Lower the brush head using the test mode and
allow the brushes to rotate for approx. 3 sec.
– Raise the brush head and move the unit away
from the chalked area.
– Check the brush pattern (2, 3).
– The brush pattern of both brush rollers must
be parallel. They are adjusted using the side
adjusting screws (1).
– The brush pattern of the rear brush (2) should
be set so that it is approx 1cm wider than that
of the front brush (3). This prevents the front
brush from being overloaded in cleaning mode.
– If necessary readjust the brush head setting in
the oblong hole of the bracket (see Page 57,
position 6).
