The photo shows the direction of rotation for releasing the right brush. Rotate in the opposite direction
for the left brush.
ATTENTION: This operation must be carried out using gloves to protect
against contact with dangerous solutions.
You are advised to invert the right and left-hand brushes every day. If the brushes are not new however, and
have deformed bristles, it is better to reassemble them in the same position (the right-hand one on the right,
and the left-hand one on the left), to prevent the different inclination of the bristles producing an overload on
the brush motor as well as excessive vibrations.
