Operation

Method Of Operation
General
The E26 is a vacuum scrubbing machine for wet cleaning of hard surfaced floors.

1. Scrub Head Assembly
   Lower the scrub head assembly (Fig. 3/1) via pedal before scrubbing. The brushes will rotate and the water supply turns on automatically. When the forward/reverse lever is in the neutral position & machine is stopped, the scrub brushes & water supply is switch off automatically. Figure 3 represents the Disc scrub Head type machine. A Cylindrical Scrub Head machine is also available.

2. Clean Water Tank
   Fill the clean water tank (Fig. 3/2) after folding up the opening. The clean water tank holds approximatly. and the filling level can be seen looking through the transparent hose. Regulation of water amount is available via adjustment handle.

3. Squeegee
   The movable squeegee (Fig. 3/3) consists of the squeegee lift handle, the vacuum motor and the squeegee blades. The dirty water is cleaned from the floor by means of the squeegee blades.

A second actuation of the lever lifts the squeegee up again and the vacuum motor is automatically switched off with a delay of 15 seconds.

4. Dirty Water Recovery Tank
   The dirty water is moved from the squeegee to the dirty water recovery tank (Fig. 3/4) by a vacuum motor and suction hose. For cleaning and collecting water in places where access is diffi cult, the machine is equipped with a handheld suction hose.

5. Drive System
   The machine features a continuous drive (Fig. 3/5). The electronic drive controls travel speed and direction as well as dynamic braking.

6. Batteries and Charger
   The machine is equipped with maintenance- free 180 Ah batteries (Fig. 3/6), , an automatic charger (Fig. 3/7) and a low discharge signal sender (LDS) for protection against low discharge.

7. Options

   • Extraction hose including suction pipe, joint nozzle and wet suction nozzle.

4. Suction hose
5. Fastening device
6. Washers for height adjustment

• Cleaning the Squeegee
  Check the squeegee (Fig. 11/1) daily and clean as necessary. To clean it lift the squeegee out, pull off the suction hose (Fig. 11/4), loosen the two star- shaped knobs (Fig. 11/2) and remove the squeegee.

• Changing the Squeegee Blades
  Check the inner and outer squeegee blades on the squeegee (Fig. 11/1) weekly for signs of wear. The squeegee blades can be re-used by turning them.

1. Lift the squeegee out.
2. Pull off the suction hose, loosen the two star-shaped knobs and remove the squeegee.
3. Unlock the fastening device (Fig. 11/5) and remove the outer squeegee blade. Turn the squeegee blade or install a new one, as necessary. Change the inner squeegee blade in the same way.

• Adjusting the Blades Angle Adjustment
  The angle adjustment is the decisive factor in ensuring that the squeegee blades on the squeegee lie evenly on the floor.

1. Park the machine on a level surface and lower the squeegee.
2. Loosen the counternut on the adjusting screw (Fig. 12/1) and adjust the squeegee using the adjusting screw so that the ends of the squeegee blades have contact with the floor.  

Figure A: Turn the adjusting screw counterclockwise: The clearance between squeegee blade and floor is reduced in the center.
Figure B: Turn the screw clockwise: The clearance between squeegee blade and floor is increased in the center.

3. Switch the machine on and check the suction pattern. When the machi-ne is in operation, the entire surface of the sealing strips (center and outer areas) must be applied as evenly as possible.
4. Tighten the counternut on the adjusting screw at 5 lb ft.

Height Adjustment
The height adjustment is set to 3mm at the factory. If streaks are produced, despite an optimum angle adjustment, the clearance between the casters and floor must be adjusted by changing the number of washers on the holder.

• In case of very smooth floors, e.g. fi nished floors, PVC, linoleum, etc. Number of washers = 2. This corresponds to a clearance of approximately 2mm.
• In cases of very uneven floors, e.g. poorly laid tiles (water does not run off ) Number of washers = 4. This corresponds to a clearance of approximately 4mm.

The squeegee is equipped with two additional casters which are adjusted at the factory to a distance of 10mm to the floor by means of spacers.
