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.
2.3.1 Solution tank
The solution tank Fig. 9-5 is filled via a hinged opening. The solution tank has
a capacity of 75 litres. The level can be determined via a transparent hose
Fig. 9-6. Fresh water metering can be set via an adjusting lever Fig. 8-21.
2.3.2 Brush head
The brushes in the brush head Fig. 9-9 are driven by an electric motor. The brush head is lowered with the brush head 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 can be decoupled via the foot
lever brush decoupler Fig. 7-8.

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.
2.3.4 Waste water tank
The vacuumed waste water is conveyed via a suction hose Fig. 10-28 from the squeegee into the waste water tank Fig. 10-18. A manual suction tool is
optionally available for cleaning and water absorption in difficult-to-reach positions.
2.3.5 Drain hose for waste water
The waste water is drained from the waste water tank with the drain hose
Fig. 10-26.

3.4.2 Useful clean in g 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 cleaning agent suitable for the degree of soiling; the squeegee remains raised for this. Leave the cleaning agent for approx. 5 to 10 minutes; subsequently scrub the floor again and work with a lowered squeegee.
3.4.3 Turning off the machine
1. Slowly bring the accelerator pedal to the zero position. The machine slows down to standstill. A better braking effect is achieved when the machine is slowed down by applying the brake.
2. Bring the driving direction selector switch to the zero position.
3. Switch off the cleaning functions.
4. Turn off the machine with the key switch and hold it with the parking brake.
Note
• Use only cleaning agents suitable for automatic machines (foam retarded). We recommend use of our cleaning and care agents specifically developed for the machine. These products meet the requirements of the German Detergent and Cleaning Agent Act (WRMG).
• Observe correct metering of the cleaning agent. Correct metering saves money and protects the environment. Strong foam formation is a sign of excessive metering and impairs machine operation.
Note
Remove the key when leaving the machine to prevent unauthorised use.
