5.3 Readjusting the main brooms
The height of the main brooms can be adjusted to obtain the best possi-
ble cleaning results of the area to be swept and to effectively exploit the
efficiency of the main brooms.
The main brooms need to be lowered once the sweeping performance
starts to wane due to wear and tear of the main brooms, or if the area to
be swept is not level.
If pushing the sweeper seems to become harder and you can hear the
main brooms scratching the ground, you will have to raise the main
brooms to ensure you use the sweeper ergonomically and to prevent
the main brooms from wearing prematurely.
On principle, the main brooms should be set to ensure that they touch
the ground at slight pressure.
