User manual NILFISK SCRUBTEC 233

[. . . ] Before performing any procedure on the machine, the operators and qualified technicians must read this Manual carefully. Alto will not be answerable for damages coming from the non-observance of this prohibition. The User Manual must be kept near the machine, inside an adequate case, away from liquids and other substances that can cause damage to it. The declaration of conformity, supplied with the machine, certifies the machine conformity with the law in force. [. . . ] Open the covers (51 and 58) and check that the tanks (60 and 61) are empty, otherwise empty them through the drain hose (10) and the tap (24). If a battery box is installed, place it on the left side of the machine, to allow the tank assembly (71) to be closed correctly. When starting the machine, check that between the deck (4 or 5) and the machine, or between the squeegee (12) and the machine, there is no foreign material which may prevent the deck or squeegee from lifting. This check is necessary because, if the machine has been turned off without lifting the deck and the squeegee, the deck and the squeegee will lift automatically at next machine start-up. The machine can be equipped with either the brush/pad-holder deck (4) or the cylindrical brush deck (5). for deck installation/removal see the procedure in Maintenance chapter. NOTE When the deck is installed/removed, it may be necessary to change the squeegee too, because they must have the same width. According to the kind of cleaning to be performed, the machine can be equipped either with brushes (88) or pad-holders (89) with pads (90) together with the appropriate deck. for the installation/removal , proceed as follows. Insert the ignition key (41) and turn it to "I". Before turning on the switch (34), always check that between the deck (4) and the machine there is no foreign material which may prevent the deck from lifting. Start scrubbing, by starting it with the hands on the steering wheel (2) and by pressing the pedal (3) as necessary. It is not necessary to lock the machine during stopping or parking, because the electromagnetic brake (27) turns on automatically when the gear pedal is not pressed. NOTE For correct scrubbing/drying of floors at the sides of the walls, Alto suggests to go near the walls with the right side of the machine as shown in figure 2. If necessary, stop the machine and turn the squeegee adjusting handwheel (16) so that the rear blade touches the floor along all its length. To avoid any damage to the floor surface, turn off the brushes/pad-holders when the machine stops in one place, especially when the extra pressure function is on. Working with brush/pad-holder extra pressure function turned on NOTE When the cylindrical brush deck is installed, the extra pressure function is not enabled. If the floor proves to be particularly difficult to clean, it is possible to turn on the brush/pad-holder extra pressure function by pressing the switch (35). To return to normal pressure, press the switch (35) again. The switch (35) is enabled only when the deck (4) is lowered and the switch warning light (34) is on. In case of brush/pad-holder motor overload, due to foreign bodies which prevent them from rotating, or to excessively aggressive floors/brushes, the safety system stops the brushes/pad-holders after about one minute of continuous overload. The overload is shown by the three warning lights (37a, 37b, 37c) flashing simultaneously. [. . . ] Connect the battery charger cable (8) to the electrical mains (the electrical mains voltage and frequency must be compatible with the battery charger values shown on the machine serial number plate). NOTE When the battery charger is connected to the electrical mains, all machine functions are automatically cut off. When the green warning light (H) turns on, the battery charging is completed. When the battery charging is completed, disconnect the battery charger cable (8) from the electrical mains and wind it round its housing (7). [. . . ]
