There are 2 types of adjustments that can be carried out on
the squeegee:
Inclination adjustment (ALL VERSIONS) with knob
(position 1).
It adjusts the inclination of the squeegee in order to have
a constant pressure over the entire length of the blade
(position 2).
Turn the knob counter-clockwise if there is too much
pressure on the outer points and little pressure on the
central area.
Turn the knob clockwise if there is little pressure on the
outer points and too much pressure on the central area.
To make the adjustment lower the squeegee, turn on the
suction fan and drive forward slowly. Examine the
pressure distribution on the blade and if necessary
correct the inclination as described above.
