Replacing brushes

Two brushes are installed in the device which should be
replaced when they become worn.
One brush is replaced from the left-hand side and the

other from the right-hand side. The procedure is the
same.
9.6.1 Adjusting the sweeping level (brush contact pressure)
Clean the roller brush retainers before inserting the

new brushes.
The brushes are inserted in the reverse sequence.

The sweeping level should be between 5-6 cm.

The adjustment of the sweeping level (brush contact pres-
sure) is set with the rotary potentiometer in the control pan-
el.
Rotate the potentiometer to the right until the lowering

brushes exhibit the correct sweeping level (brush con-
tact pressure).
Is the sweeping level too large, rotate the potentiometer

back.
