The various operating and indicator elements are described in Chapter 3.2 Operating and indicator elements. The working steps to fill the solution tank, empty the recovery tank and other maintenance tasks are described in Chapter 5 Maintenance and Service.

3.1 Method of operation

3.1.1 General information

The Scrubmaster B100R is a floor scrubbing vehicle conceived for the wet cleaning of hard floors.



Fig.3

Operation

3.1.2 Scrubbing

The figures in this operating manual generally illustrate the rotary brush head. The vehicle can also be equipped with a circular brush head.

The vehicle implements a brush head (Fig. 3/1) with two rotating brushes for the scrubbing operation. You must decide whether to use a brush head with circular brushes or roller brushes. When scrubbing mode is activated, the brush head is automatically lowered by an electric servomotor on starting to drive, the brushes start to rotate and solution supply to the nozzles is automatically activated. When the vehicle is stopped, the brush head is automatically raised and the brushes and solution supply are switched off. The solution tank (Fig. 3/2) provides the solution necessary for the scrubbing operation.

3.1.3 Vacuuming

After scrubbing, the resulting dirty water on the floor is normally vacuumed up. To do this, the adjustable squeegee

(Fig. 3/3) draws the waste water from the floor by means of a sealing strip. When vacuuming mode is activated, the squeegee is automatically lowered by an electric servomotor on starting to drive and the suction turbine is switched on. When driving in reverse, the squeegee remains in its raised position. The dirty water drawn up by the squeegee is fed into the recovery tank (Fig. 3/

4).

3.1.4 Driving

The vehicle is driven by an electric motor on the front wheel (Fig. 3/5). The electronic control unit converts the position of the throttle and throttle to driving speed, driving direction and deceleration. The vehicle is provided with the electrical power necessary for operation from batteries (Fig. 3/6). The batteries must be recharged regularly by means of an external charger.

3.1.5 Options

• Scrubbing-vacuuming tool for spraying, scrubbing and vacuuming. It serves to clean areas which the vehi cle cannot access.

To connect the scrubbing-vacuuming tool, disconnect the top end of the suction hose from the vehicle nozzles and connect the hose from the scrubbingvacuuming tool. The solution hose continues to be connected to the coupling beside the nozzles. The scrubbing-vacuuming tool is ready for operation after pressing the relevant switch below the steering wheel. A brush and suction adapter, which can be screwed out and changed, are mounted at the bottom end of the extendible telescopic rod. When the grip switch is pressed, a jet of the solution is sprayed out of the nozzle above the brush.

Fig.4

Operation

Solution tank (Fig. 4/1)

The solution tank contains the solution required for the scrubbing operation, the solution being made up of water and cleaning agents. The solution is supplied from a fresh water pipe at the bottom, the pipe connecting both sides of the tank. The solution is drawn by the solution pump and forced to the nozzles which are arranged in front of the rotary brushes. The electric valve prevents the tanks running empty when the vehicle has stopped. The solution tank has a volume of 100 liters.

Solution tank filling neck (Fig. 4/ 2)

The filling neck is closed by means of a screw cap and is used for filling the solution tank.

Solution tank indicator (Fig. 4/3)

A transparent hose connected to the solution tank serves as a fill level indicator.

Solution draining hose (Fig. 4/4)

In order to complete service work or transport the vehicle, for example, the solution tank can be emptied by means

of a draining hose.

Recovery tank (Fig. 4/5)

The recovery tank collects the waste water drawn up by the squeegee. It is fed to the recovery tank by means of the intake air current via the suction hose. Due to the tank volume, it acts as a separator, so that the waste water and waste vacuumed up fall from the air current. The air flows on via the air intake filter and fine particle filter to the suction turbine and is then discharged. The recovery tank has a volume of 96 liters.

Recovery tank locks (Fig. 4/6)

Locks on both sides fix the recovery tank, which can be tilted, firmly to the vehicle. The recovery tank may only be tilted when empty or almost empty. A strap restricts the tipping angle.

Waste water draining hose (Fig. 4/7)

The waste water can be drained from the recovery tank through the draining hose. The draining hose is connected directly above the base of the recovery tank so that to empty it, only the draining end of the draining hose needs to be

disconnected from the holder and laid to a floor drainage system, for example. A reducer can be mounted on the draining end to reduce the escaping flow, thus preventing the floor drainage system overflowing.

Waste water drain (Fig. 4/8)

The waste water drain serves for cleaning the recovery tank and removing larger pieces of waste vacuumed up. It is comprised of a flap and a plug, located directly behind, which is plugged into the drain inlet and tightened by means of a wing nut.

Air intake filter (Fig. 4/9)

The air intake filter in the recovery tank prevents larger pieces of waste being drawn into the suction turbine.

Suction turbine fine particle filter (Fig. 4/10)

The fine particle filter located above the suction turbine ensures that no particles of dirt can enter into the suction turbine.

Operation

Waste water service access  (Fig. 4/11)

The waste water service access enables access to the inside of the recovery tank and, in particular, to the preliminary filter.

Scrubbing-vacuuming tool water connection

This water connection supplies solution to the scrubbing-vacuuming tool (option) if connected.

Solution pump (Fig. 4/13)

The solution pump feeds the fresh water from the solution tank to the nozzles near the brushes.

Solution filter (Fig. 4/14)

While solution flows from tank to the nozzles, it is cleaned by the filter element.

Operation

Rotary brush head (Fig. 5/1)

The rotary brush head is lowered and raised by means of a servomotor. The arrangement of rods for parallel extension ensure that the rotary brush head touches down parallel to the floor. Two rollers, driven in opposite directions individually by electric motors, rotate inside the rotary brush head. A jet of solution is sprayed from four nozzles located in front of the head. Larger items on the floor are swept into the waste container as a result of the rotation movement.

Side sealing strips (Fig. 5/2)

In the case of the rotary brush head, the side sealing strips prevent the sprayed solution splashing to the side under the vehicle and feed the splashed solution to the squeegee. The side sealing strips are made of rubber and screwed to the holders. They are symmetrical so that all four edges can be used by turning them before the sealing strips are worn out.

Star-sharped knob for side sealing strips (Fig. 5/3)

The star-sharped knob hold the pivoting holders for the side sealing strips in position.

Star-sharped knobs for side sealing strips (Fig. 5/4)

The two star-sharped knobs can be used to adjust the side sealing strips so that they form a seal at the bottom but are not worn too quickly as a result of too high a pressing force.

Brush cover (Fig. 5/5)

The brush covers on both sides of the brush head serve as a seal and bearings for the rotary brushes. After removing the three knobs, the brush covers can be removed and the rotary brush mounted on it pulled out of the brush head.

Rotary brushes (Fig. 5/6)

The two rotary brushes are identical. They are provided with two slits on one side which serve as holders for the drive, they are held by the brush covers on the other side.

Waste container (Fig. 5/7)

The waste container collects the items swept up by the rotary brushes.

Nozzles (Fig. 5/8)

Solution is applied to the front rotary brush by means of the four nozzles.

Deflection roller, front (Fig. 5/9)

The deflection rollers prevent damage when cleaning against walls. It also simplifies driving adjacent to walls.

Circular brush head (Fig. 5/10)

The circular brush head is extended in the same way as the rotary brush head. Two circular brushes, driven by an electric motor, rotate in the circular brush head. Each circular brush is supplied with solution from a nozzle located near the pivoting axle.

Circular brushes (Fig. 5/11)

The two circular brushes are identical. They are equipped with hooks which are hooked in the drives when changing the circular brushes.

Operation

Covers (Fig. 5/12)

The covers must be removed in order to change the circular brushes.

Star-sharped knobs for sealing strip (Fig. 5/13)

The sealing strips are fixed to the covers by means of star-sharped knobs so that they can be vertically adjusted.

The sealing strips on the squeegee are made of PU. They are fixed to the squeegee by tightening straps and lugs which project through breakouts in the sealing strips. The sealing strips are symmetrical so that all four edges can be used by turning them before the

sealing strips are worn out and have to be changed.

Deflection rollers, rear (Fig. 6/6)

The deflection rollers prevent damage when cleaning against walls. They also simplify driving adjacent to walls.

Deflecting bar (Fig. 6/7)

The deflecting bar prevents getting caught by obstructions.

Ball-head rods (Fig. 6/8)

The two ball-head rods ensure the squeegee remains in the correct position to draw up the waste water even when driving around corners.

Hanger (Fig. 6/9)

The squeegee hangs on a servomotor and is lowered or raised by it. The spring serves as a buffer and gives way in the case of obstacles.

Angle adjustment (Fig. 6/10)

The angle adjustment is used to set the squeegee so that it is held tipped slightly towards the rear, thus ensuring both sealing strips make correct contact with the floor.

Pivoting axle (Fig. 6/11)

When adjusting the angle, the squeegee is turned about the pivoting axle.
