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.

Do not cover these plates for any reason and immediately replace them if damaged. Turn off the machine by turning the ignition key (41) to "0". Press and hold the switch (36), then turn on the machine by turning the ignition key (41) to "I". Release the switch (36) at least 5 seconds after starting the machine. Within three seconds, press the switch (36) again for a few seconds and check that the warning light for the required setting is flashing. Turn the selector (C) to WET or GEL according to the type of batteries installed. 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. 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). 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. If the overload takes place when the extra pressure function is on, the system automatically reduces the pressure on the brushes/pad-holders, thus turning the extra pressure function off. To start scrubbing again after a brush/pad-holder stop due to overload, stop the machine by turning the ignition key (41) to "0". [. . . ] Remove the transparent cover (A), then remove the filter strainer (E) under the machine, in front of the right rear wheel. NOTE The filter strainer (B) must be correctly positioned on the housing (D) of the support (C). NOTE Charge the batteries when the yellow or red warning light (37b or 37c) turns on, or at the end of every working cycle. When the batteries are discharged, charge them as soon as possible, as that condition makes their life shorter. [. . . ]
