Replacing the sealing skirts
Direction of travel
The sealing skirts fulfil an important function. They retain the
partial vacuum in the area round the brushes which is es-
sential so that the sweeper can function properly. They
ensure that sweeping can take place without clouds of dust
being formed at the same time. If the sealing skirts are
damaged or worn out, they must be replaced immediately.

Remove the retaining screws and detach the sealing
skirts.

Fit new skirts, and align them as follows:
The side skirts should be adjusted so that they clear the
ground by 1–3 mm.
