Squeegee System 105 Service Manual – SC3000
Squeegee System
Functional Description
The squeegee system cleans the liquid off the floor, which is then collected by the recovery system.
The squeegee is mounted on castors and the weight of the system presses it down on the floor.
The squeegee is held in place by two quick-fit wing nuts in the squeegee support slots. In case of fixed ob-
stacles, the quick-fit system allows for squeegee immediate removal.
The squeegee support is held on the frame by two tie rods and a centring spring, allowing some lateral move-
ment.
The angle of the squeegee and the correct adherence of the blades on the floor can be adjusted with a knob.
The front blade has an opening in the bottom edge so the squeegee can collect the water on the floor. The design
and the central duct make it easy for the squeegee to clear the water. The bottom edge of the blade is smooth.
All 4 functional edges of each blade can be used before it needs replacing.
The squeegee is lifted and lowered by a cable on a winch in the solution tank. It is activated at the same time
as the brush deck.
The squeegee actuator (M6) has 2 limit microswitches (not accessible). Every time it is raised or lowered, the
actuator is activated by the electronic board for 10 seconds. The squeegee must reach the correct limit switch
by the end of this time.
In any case the electronic board cuts off the power supplied to the actuator after 10 seconds, to prevent damag-
ing the actuator.
