The rotation wheel can be used to set the contact
pressure and for appliances without travel drive the
propulsion speed.
Contact pressure / reduce speed:

Turn the rotation wheel to the left.
Contact pressure / increase speed:

Turn the rotation wheel to the right.
If the rotation wheel is turned to the right, the thread-
ed rod pushes the contact roller hookup down and
the contact roller presses against the disc brush.
The disc brush is pressed onto the ground harder,
which increases the propulsion speed (only for appli-
ances without travel drive).
