2.3 General principle of operation

Scrubmaster B120 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 unit. When the machine is moving forwards, the used waste water is absorbed by the squeegee and conveyed into the waste water tank.

2.3.1 Solution tank

The solution tank Fig. 9-6 is filled via the filling opening Fig. 4-20. The solution tank has a capacity of 120 litres. The level can be determined via a transparent hose Fig. 10-30. If there are only 10 litres of fresh water left in the tank, the ball cock symbol flashes in the display panel and a warning sound (approx. 30 seconds) requests refilling.

2.3.2 Brush unit

The brushes in the brush unit Fig. 9-8 are driven by two electric motors. The brush unit is lowered with the brush unit button Fig. 5-36. When actuating the accelerator pedal, the brush motors and the water supply are switched on. The floor is cleaned by the rotating brushes and the supply of cleaning solution. For maintenance purposes, the brushes in the rotating brush unit can be decoupled via the foot lever brush decoupler Fig. 8-7.

3.4.6 Useful cleaning tips

Sweep the floor before carrying out wet cleaning. This not only enhances the cleaning effect but also reduces wear of the machine's working tools. If the floors are really dirty or wax needs to be removed, treat the floor twice. In the first step, scrub the floor with a detergent suitable for the degree of soiling; the squeegee remains raised for this. Leave the detergent for approx. 5 to 10 minutes; subsequently scrub the floor again and work with a lowered squeegee.

Note

• Only use detergents suitable for automatic machines (foam retarded). We recommend use of our detergents and care agents specifically developed for the machine. These products meet the requirements of the German Detergent and Cleaning Agent Act (WRMG).

• Observe correct dosing of the detergent. Correct dosing saves money and protects the environment. Strong foam formation is a sign of excessive dosing and impairs machine operation.
