SQUEEGEE ADJUSTMENT
The squeegee must be perfectly adjusted to get a perfect floor drying. ICM 38 is equipped
with a V-shaped squeegee, as shown in (fig.). This type of squeegee performs very well in
collecting water from the floor to the suction hose, but is particularly sensitive to the paralle-
lism to the floor. Therefore, adjust first its angular position through the screws (fig.) so that its
rubber blades get the same slanting on the floor along its entire width. If blades are
more pressed at their ends than in their centers, unscrew the upper screws (fig.) and screw
the lower ones (fig.), then tighten the lock nuts. If, on the contrary, blades are more pres-
sed at their centers than in their ends, perform the opposite operation. After having rea- ched
the right angular position, adjust the pressure. Turn the ring nut (fig.) and tighten it to
increase pressure to the floor, or loosen to decrease it. The right pressure is got when the
edge of the rear blade touches the floor with a slanting of approx. 60°-45° referring to the
floor. If the pressure is too high, the rear blade will touch the floor with its side surface, and
not with its edge. If the pressure is too low, the edge doesn’t work well and lets some water
on the floor, particularly on an uneven floor. Of course the optimal adjustment is confirmed
by very good results of the drying operation, and the operator’s experience will contribute
to enhance such good results. Note that often drying is negatively affected by a wrong suc-
tion operation. If the suction hose doesn’t work well, drying will continue to be bad, even
with all adjustments attempts. In this case:
a) accurately clean the suction hoses, their inlets and filters and the squeegee itself
b) check the vacuum motors operation
c) confirm that all inspection openings of the tank are closed.
