Maintenance and Servicing Waste water tank Fig. 22: 5.5.1 Emptying the waste water tank Empty the waste water tank Fig. 22-18 daily, as required or when an acoustic signal is output (increased suction turbine speed). Environmental danger Observe applicable laws and local regulations when disposing of cleaning agents! Fig.
Maintenance and Servicing 4. Remove the drain hose from the holder. Push the suction hose Fig. 23-A slightly to the side so that the waste water tank can be emptied fully via the drain hose. 5. Bend the squeeze nozzle in the front section Fig. 23-B. 6.
Maintenance and Servicing 5.5.3 Cleaning the suction filter Check the function of the suction filter Fig. 24-17 daily and clean it as required. 1. Remove the suction filter from the neck. 2. Clean the suction filter under running water. 3. Mount the suction filter on the neck again. 5.5.4 Checking the gasket at the drain hose Fig.
Maintenance and Servicing Brush head 7175.1x 7175.2x/.30 Fig. 27: 5.6.1 Cleaning the brushes Clean the brushes Fig. 27-A in the brush head Fig. 27-9 daily or as required. 1. Decouple the brush, see section 5.6.3. 2. Thoroughly clean the brush under running water. 3.
Maintenance and Servicing 5.6.2 Changing the brushes Use the indicator Fig. 28-A on the brush head to: • determine the wear of the brushes. • determine whether the brushes have been assembled. Fig. 28: Change the brushes at the latest when the red pointer is in the red zone. 1.
Maintenance and Servicing 5.6.4 Coupling the brushes Variant 7175.1x: 1. Turn on the machine. 2. Position the brushes centrally to the brush head. 3. Push the brush head button Fig. 27-36 or the brush head and squeegee button Fig. 27-37. 4.
Maintenance and Servicing Squeegee Optimum vacuuming is achieved through: • Clean and undamaged or not worn sealing strips. • Correctly set inclination angle and correct height adjustment of the sealing strips. Fig. 30: 5.7.1 Cleaning the squeegee Check the squeegee Fig. 30-23 daily for soiling and foreign particles and clean it as required.
Maintenance and Servicing 5.7.2 Replacing the sealing strips Check the sealing strip Fig. 31-G and slot strip Fig. 31-H at the squeegee weekly for wear and intactness. If the used sealing edge of the sealing strip is worn or damaged, turn or replace the sealing strip. Each sealing strip can be used four times before it needs replacing.
Maintenance and Servicing 5.7.3 Adjusting the sealing strips Inclination adjustment The correct inclination adjustment is decisive for: • Ensuring that the sealing strips of the squeegee rest evenly with the complete contact surface on the ground. • Ensuring that the squeegee runs smoothly and evenly during the suction process.
Page 69
Maintenance and Servicing Height adjustment The height adjustment (X) of the supporting rollers Fig. 34-F has been set to 3 mm in the factory. If striping still occurs despite optimum inclination adjust- ment, set the distance of the supporting rollers to the lower edge of the sealing strip by adjusting the number of washers under the supporting roller holder.
