Operation 2.3 General principle of operation Scrubmaster B75 R is a ride-on scrubber-drier for wet cleaning hard floor surfaces. In cleaning mode, the cleaning solution is supplied from the solution tank to the rotating brushes in the brush head. Fresh water metering takes place manually via an adjusting lever. When the machine is moving forwards, the used cleaning agent is absorbed by the squeegee and conveyed into the waste water tank. 5 6 25 8 9 Fig. 9: 2.3.1 Solution tank The solution tank Fig.
Operation 2.3.3 Squeegee The movable, hinged squeegee Fig. 9-25 is lowered and switched on with the squeegee button Fig. 5-35. The squeegee withdraws the waste water from the floor using a sealing strip. The suction turbine vacuums the waste water from the floor. If the machine passes through narrow sections, e. g. checkout areas, the squeegee can be removed by loosening the star-shaped handle and hooked into the cover Fig. 10-A of the waste water tank.
