Changing the rotary brushes
Check the rotary brushes on a
weekly basis for signs of wear.
When a rotary brush has worn to a diam-
eter of approx. 3.9 in, the rotary brushes
must be replaced by new ones (diameter
of new rotary brush: 5.4 in).
To protect the floor surface, the
rotary brushes are equipped
with a wear restriction facility.
When the minimum diameter is
reached, the rotary brush head
lowers onto a vertical stop. The
full cleaning performance can no
longer be achieved when in this
position.
