BATTERY RECHARGER Make sure that the battery recharger is suitable for the installed batteries both for their capacities and type (lead/acid or GEL). In the plastic bag containing the use and maintenance you will find the coupling connector for the recharger. It must be assembled onto the cables of the recharger, following the instructions given by the manufacturer. INCORPORATED BATTERY RECHARGER (OPTIONAL) If the machine is equipped with the incorporated battery recharger (see under "OPTIONAL ACCESSORIES”) please refer to the instructions of the constructor of this accessory what the recharging operations concern. The battery recharger is connected directly to the battery poles. During the recharging operations a device is activated which does not permit the machine's functioning. The mains cable of the battery recharger has a maximum length of two metres and must be connected to a single-phase socket type CEE 7/7. In this way it will be possible to handle the batteries with suitable lifting equipment. BATTERY INSTALLATION The machine is equipped either with batteries in serial connection or elements of DIN-type assembled together and connected in series for a total of 24 Volt, placed in its appropriate compartment under the seat platform and must be handled using suitable lifting equipment (due to weight, considering the type of batteries chosen, and coupling system). The batteries must be in accordance with CEI 21-5 Norms. The machine and its battery check card foresee the use of traditional lead batteries. CHECK THE SETTING OF THE CHECK CARD (see under paragraph "BATTERIES CHARGE LEVEL INDICATOR"). In case of GEL batteries installation, it is necessary to MODIFY THE SETTING of the electronic check card (see under paragraph SETTING OF THE BATTERY CHECK CARD”). BATTERIES RECHARGING 1. Plug the connector (2) of the battery recharger into the battery connector (1). 2. Proceed for the recharging. Once that the battery recharging has been completed: 3. Disconnect the connector of the battery recharger (2) from the battery connector (1). 4. Connect then the battery connector (1) to the machine connector (3). Strictly follow manufacturer/distributor indications for the maintenance and recharge of the batteries. All installation and maintenance operations must be executed by specialized staff, using suitable protection accessories. 8 CONNECTION BATTERIES' CONNECTOR AND SWITCHING ON OF THE MACHINE Once that the battery recharging has been completed: 1. Disconnect the connector of the battery recharger from the battery connector (1). 2. Connect instead the machine connector (2). BATTERIES (OPTIONAL) RECHARGING WITH ON-BOARD CHARGER Bring the machine on a levelled surface near to a single-phase socket with tension 230V, frequency 50Hz, nominal current 10A. Switch off the switches of the brushes motor, the suction motor and the solenoid valve. 1. Insert the plug into the mains socket. 2. Proceed to the recharging keeping the seat base lifted (see under paragraph “ACCESS TO THE BATTERY COMPARTMENT” in “BEFORE USE”). 3. Do not take off the plug from the mains socket until the indication of the end of charge is not visualized. At the end of the recharging, take off the plug from the mains socket. BATTERIES CHARGE LEVEL INDICATOR To start any function of the machine, it is necessary to rotate clockwise the key switch (A). Rotating it counterclockwise any function will be switched off. WHEN THE MACHINE IS SWITCHED ON, ON THE DISPLAY (1) APPEAR IN SEQUENCE THE FOLLOWING INFORMATION: 1. the machine model (for example AdL). Never charge a GEL battery with a non suitable recharger. Strictly follow the instructions supplied by the batteries and recharger manufacturer. In order not to cause permanent damages to the batteries, it is necessary to avoid their complete discharge, providing for the recharging within a few minutes after that the batteries’ discharge signal starts blinking. NOTE: Never leave the batteries completely discharged even if the machine is not used. In case of traditional batteries, please check the electrolyte level every 20 recharging cycles and eventually top them up with distilled water. Never leave the batteries discharged for more than two weeks. 2. Danger of gas exhalations and emission of corrosive liquids. Fire danger: do not approach with free flames. BATTERIES DISPOSAL It is compulsory to hand over exhausted batteries, classified as dangerous waste, to an authorized institution according to the current laws. 9 the setting of the battery check card which can be: GE 24 (check card set for GEL batteries). or Pb 24 (check card set for lead batteries). 3. The machine, if not specified otherwise, is supplied with the battery check card set for lead batteries. To modify this setting, it is necessary to: 1. Switch off and on the machine. 2. Immediately after having switched on, when on the display (1) the writing Pb24 appears, press simultaneously the push buttons (2) and (3) up to the blinking of the writing. 3. When the writing begins to blink, take off the fingers from the push buttons and press once the push button (3). 4. The writing GE24 appears blinking. 5. When the writing stops to blink, the setting is modified. 6. For the passage of the setting from gel batteries into lead batteries, repeat the procedure pressing button (2) instead of button (3). the version of the software programme of the card (for example 5-9). As the machine is a 24V model, do not set the batteries at 36V. 4. The batteries charge level indicator is digital and remains fixed on the display. The battery charge level starts from -100-, which indicates the 100% of the total charge and decreases from 10 to 10. When the charge level reaches -20-, the display starts blinking, so you are about the end of working. When the indication -10- appears blinking, automatically the brushes stop, while the suction continues to work. When visualizing the four lines blinking, also the suction will stop automatically. Instead, the traction system remains functioning to enable the transfer of the machine to the place provided for the tank emptying and for the recharge of the batteries. SETTING OF THE BATTERY CHECK CARD The setting of the battery check card can be: GE 24 (check card set for GEL batteries). or Pb 24 (check card set for lead batteries). 10 HOUR METER The machine is equipped with an hour meter located on the same display (1) of the battery charge level indicator. Keeping the button (2) pressed, the first data indicates the working hours and after a few seconds the working minutes are shown. The lower part of the rubber is not much bent Increase the pressure rotating the wing nut (6) clockwise. Check that the wheels which adjust the height do not rest on the floor, in this case adjust them as indicated in paragraph "Height adjustment". The bending is not uniform Adjust the squeegee inclination rotating counterclockwise the wing nut (7) to increase the bending in the central part, or clockwise to increase the bending on the extremities. Height adjustment Once that the pressure and inclination of the squeegee have been adjusted, it is necessary to fix this optimum condition making touch slightly the wheels onto the floor. Rotate the registers (8): clockwise to lower the wheels or counterclockwise to raise them. Both wheels must be adjusted in the same measure. SQUEEGEE ASSEMBLY 1. Maintain the squeegee support (1) slightly lifted from the floor. 2. Insert the threaded parts of the two knobs (2) making them slide inside the two slots present on the support. 3. Put the washers (3) into position, they are two for each knob, so that they are assembled one under and the other on each of the two slots present on the support. 4. Block the squeegee by rotating the two knobs (2) clockwise. 5. Insert the squeegee hose (4) into its coupling, respecting its position as indicated in the figure. Every type of floor requires a specific adjustment. For example, concrete floors (where the friction results to be high) need little pressure, while smooth floors (ceramics) need higher pressure. If the cleaning operations are made always on the same type of floor, the adjustment can change only in function of the rubber wear. SPLASH GUARD ASSEMBLY The two splash guards have to be assembled onto the brushes base group as indicated in the following figures. Insert the metal strips inside the suitable slots present on the rubber. Place the round hole at the extremity of the strip onto the pin (1) placed in the front part of the brushes base group. Secure the strips through the nut blocking it. Block the coupling lever (2) in the rear part of the brushes base group to the ring placed at the extremity of the metal strip still free. Please act as above for both splash guard rubbers. With the brushes assembled, the splash guard must slightly touch the floor. For the disassembly it is necessary to proceed inversely with abovementioned operations. ADJUSTMENT OF THE SQUEEGEE In order to have a perfect drying result through the squeegee, the rear rubber must have the lower bending uniformly adjusted in all its length. For the adjustment, it is necessary to put oneself in working condition and therefore the suction motor has to be switched on and the brushes have to function together with the detergent solution. The lower part of the rubber is too much bent Take off the pressure rotating the wing nut (6) counterclockwise. 11 FLOOR CLEANING RECOVERY TANK Check that the cover of the suction filter (1) is correctly secured, after rotating the levers (2) and that the suction motor hose (3) is correctly connected to it. Verify also that the squeegee hose couplings (4/5) are correctly inserted into their seats and that the exhaust hose plug (6) placed in the rear part of the machine is well closed. BRUSHES ASSEMBLY To assemble the brushes it is necessary that the brushes base is in the lifted position. If it is not lifted, proceed as follows: Without the operator seated, turning the key switch clockwise, the display comes on and after 3 seconds all working groups come off automatically and are lifted from the floor. Switch off the machine turning the key counterclockwise. With the brushes base group in lifted position, insert the brushes into their plate seat underneath the brushes base turning them until the three metal buttons are properly seated in their slots; rotate energically the brushes to push the button towards the coupling spring until they get blocked. The figure shows the rotating sense for brushes coupling. DETERGENT SOLUTION TANK The capacity of the detergent solution tank is indicated in the technical data. Open the screw plug placed in the left part of the machine and fill the detergent solution tank with clean water at a maximum temperature of 50°C. Add the liquid detergent in the percentage and conditions foreseen by the manufacturer. To avoid excessive foam presence, which could cause problems to the suction motor, use the minimum percentage of detergent. Screw down the plug to close the tank. For a longer life of the brushes we suggest to invert daily their position. Whenever brushes result to be deformed we suggest to reassemble them in the same position, in order to avoid that the different inclination of the bristles causes excessive motor overload or troublesome vibrations. Use always low foam detergent. To avoid foam presence, before starting working operation, introduce into the recovery tank a minimum quantity of anti-foam product. Never use pure acid. 3SD SYSTEM SOLUTION SAVING SYSTEM DISPENSER (OPTIONAL) The system permits the predetermined dosing of the detergent percentage which will be mixed with the water of the solution tank. The detergent is contained in a transparent tank with a capacity of 8 litres, placed in the front part of the machine. Use only brushes supplied with the machine or the ones indicated in the manual “RECOMMENDED BRUSHES”. The use of other brushes can compromise the good washing result. 12 NOTE: when restarting with the work in mode 3SD, it is important that the solution valve (C) is closed, this to maintain the predetermined proportions water-detergent. NOTE: if the automatic dosing system is not being used for a long time, it is possible that the hoses of the detergent circuit are emptied and therefore at the first use, the detergent begins to come out onto the brushes with a certain delay compared to the water outlet. Through the solution valve (D) it is possible to empty the detergent tank and to recover the detergent. With the brushes moving, pressing once the push button (A) on the instrument board, on the display (1) the indication shows the detergent percentage which is being used. Pressing the same push button in succession, six different possibilities of settings can be selected and the display (1) visualizes always the percentage. The indication of the level corresponds to the following detergent percentages in the water: d 0.0 d 0.3 d 0.6 d 1.2 d 2.4 d 4.5 STARTING OF THE MACHINE A safety device avoids the machine’s movement if the operator is not seated correctly on the guiding place. To switch on the machine: 1. Sit on the guiding place. 2. Adjust the seat position through the release lever placed on the left. 3. Turn the key switch (1) clockwise to switch on the machine. Automatically, the machine gets ready in manual (MAN) mode and in forward movement with the quick speed (signal lamp 2). 4. Check the charge level of the batteries on the display (3). 5. Pressing the push button (7) the functioning of BREAK WASHING is chosen and the transfer operations of the machine are carried out (see under paragraph “FORWARD AND BACKWARD MOVEMENT"). When the signal lamp (6) is on, then the machine is in BREAK WASHING mode. 6. Pressing the push button (8) the automatic (AUTO) functioning is chosen, while pressing the push button (5), the functioning of the machine becomes manual (MAN). A. When the signal lamp (9) is on, the machine is functioning in automatic (AUTO) model and the machine activates and deactivates all the working functions in an automatic mode (see under paragraph “WORKING IN AUTOMATIC MODE”). B. When the signal lamp (4) is on, the machine is functioning in manual (MAN) mode and it is possible to choose if: I. to carry out the only transfer of the machine without activating or deactivating the working functions. II. to activate separately only the controls relative to the washing function with the brushes (see under paragraph “WORKING IN MANUAL MODE”). III. to activate separately only the controls relative to the drying function with the squeegee (see under paragraph “WORKING IN MANUAL MODE”). The dosing adjustment set remains stored by the system also with the machine stopped. The water flow is adjusted through the 8-way commutator (B): one OFF position and 7 operating positions from a minimum of 1,2 litres/min to a maximum of 3,7 litres/min. In OFF position both the water flow and its relative detergent flow is interrupted. When the commutator (B) is in OFF position, an auxiliary water system can be activated, that permits the traditional use of the machine and therefore the filling of the solution tank with water and detergent. In this case it is necessary to open and adjust manually a solution valve (C) placed under the machine. In this situation the push button (A) handles the command of the solenoid valve in manual function. 13 WORKING BRAKE To stop the machine during normal working situations, it is sufficient to release the accelerator pedal, because the machine has got an electronic brake system. To restart, press again the accelerator pedal. In manual mode every function of the machine has to be activated or deactivated manually. EMERGENCY-PARKING BRAKE In case of an emergency press the pedal of the emergency and parking brake (1) placed on the left side. To insert the parking brake press the brake pedal (1) and simultaneously move downwards the lever (2) placed on the left side of the steering column. On the instrument board the signal lamp (3) comes on which signals that the parking brake is inserted. To release the parking brake, it is sufficient to press the brake pedal (1) and automatically it is released. FORWARD AND BACKWARD MOVEMENT It is recommended to carry out always the mere transfer of the machine in mode (BREAK WASHING). To proceed to activate the movement of the machine: 1. Sit on the guiding place. 2. Turn the key switch (1) clockwise to switch on the machine. 3. Check the charge level of the batteries on the display (5). 4. Pressing the push button (7) the functioning of BREAK WASHING is chosen to carry out the mere transfer of the machine. In fact, in this mode the washing functions of the machine are not working and only the traction system functions. When the signal lamp (6) is on, then the machine is in BREAK WASHING mode. 5. Check through the signal lamp (9) that the parking brake is not inserted and eventually release it (see under paragraph EMERGENCY-PARKING BRAKE”). 6. Positioning the selector (8) forward, the forward drive is chosen, while positioning it back, the rear drive is chosen. 7. Press the accelerator pedal placed on the right part of the platform to start the machine. 8. Adjust the movement speed in forward pressing every time the push button (2) to choose the slow one (at the maximum 3,6 km/h is reached) or the fast one (at the maximum 5 km/h is reached). The signal lamp (3) indicates that the fast drive is selected, while signal lamp (4) indicates that the slow drive is selected. 9. In backward movement, when the machine is moving, an intermittent warning device is activated, selecting the backwards movement the squeegee is brought automatically to the upper position. It will then lower again in the following forward movement. This happens both in automatic as in manual mode in order to protect the integrity of the squeegee. WORKING IN AUTOMATIC MODE The automatic operation is useful to simplify the operator’s work. 1. Activate the machine (see under paragraph “STARTING OF THE MACHINE”). 2. Pressing the push button (3) the automatic (AUTO) functioning is chosen. When the signal lamp (4) is on, then the machine is functioning in automatic (AUTO) mode. 3. Check that the knob of the solution valve (5) is in the position of optimum flow, depending on the type of floor and the type of dirt (see under the paragraph “FLOW ADJUSTMENT OF THE DETERGENT SOLUTION”). 4. Position the selector (2) forward to choose the forward drive. 5. Adjust the movement speed in forward with the push button (1) (see under paragraph "FORWARD AND BACKWARD MOVEMENT"). 6. Pressing the accelerator pedal, the machine begins to proceed and in automatic mode all the working functions are activated. In fact, automatically both the brushes base and the squeegee go down, the brushes begin to turn, the solenoid valve opens to permit the detergent solution to flow down onto the brushes and the suction system is activated to recover the dirty water from the floor. Positioning backwards the selector (1) to choose the rear drive and pressing the accelerator pedal the rear drive starts, the squeegee lifts automatically and will then return to lower itself during the next forward movement. If the accelerator pedal is released for more than 3 seconds, automatically all the functions are being switched off and both the brushes base and the squeegee are being lifted. Pressing again the pedal, the machine starts to move again and in automatic mode all the working functions are reactivated. HORN The machine is equipped with a horn which is activated pressing the push button (1). 14 WORKING IN MANUAL MODE The manual mode is useful when, in special cases, it is necessary to carry out separately only the washing with the brushes or only the drying of the floor. 1. Activate the machine (see under paragraph “STARTING OF THE MACHINE”). 2. Pressing the push button (2) the functioning of manual (MAN) mode is chosen. When the signal lamp (1) is on, then the machine is functioning in manual (MAN) mode. WORKING ADJUSTMENTS Both in automatic as in manual mode, during the first metres check: 1. that the squeegee adjustment guarantees a perfect drying result (see under paragraph “ADJUSTMENT OF THE SQUEEGEE”). 2. that the adjustment of the detergent solution flow is sufficient to wet the floor uniformly avoiding the leakage of detergent from the splash guards (see under paragraph “FLOW ADJUSTMENT OF THE DETERGENT SOLUTION”). 3. that the brushes pressure permits an efficient washing action in function of the dirt and the speed (see under paragraph “ADJUSTMENT OF THE BRUSHES PRESSURE”). TO CARRY OUT THE WASHING WITH ONLY THE BRUSHES: 1. Check that the knob of the solution valve (8) is in the position of optimum flow, depending on the type of floor and the type of dirt (see under the paragraph “FLOW ADJUSTMENT OF THE DETERGENT SOLUTION”). 2. Press the push button (6) of up/down of the brushes base to lower the brushes. Once that it is lowered, the brushes begin to turn. The blinking signal lamp (7) indicates that the brushes base is lowering or lifting (it remains on when the brushes base is in working position), while the signal lamp (5) signals that the brushes are turning. 3. Press the switch (4) to open the solenoid valve and permit the detergent solution to lower onto the brushes. The signal lamp (3) will come on, to indicate that the solenoid valve is open. FLOW ADJUSTMENT OF THE DETERGENT SOLUTION To adjust the detergent solution quantity that flows down onto the brushes it is necessary to act upon the solution valve knob (1) placed on the right of the steering column, rotating counterclockwise to increase it and clockwise to reduce it up to close the flow. It is better to adjust the water flow during work and at every adjustment of the brushes pressure. ADJUSTMENT OF THE BRUSHES PRESSURE Through the knob (4 it is possible to adjust the brushes pressure onto the floor in three pre-set pressure levels. We can visualize on the display (1) the pressure in kg previously set by pressing the push button (3). The adjustment occurs in this way both in automatic and in manual mode. TO CARRY OUT THE FUNCTION OF ONLY DRYING: 1. Press the push button (14) of up/down squeegee to lower the squeegee. The blinking signal lamp (13) indicates that the squeegee is lowering or lifting (it remains on when the squeegee is in working position). 2. Press the switch (12) of the suction motor to start the suction system. The signal lamp (11) indicates that the machine is drying. 3. Position the selector (9) forward to choose the forward drive. 4. Adjust the movement speed in forward with the push button (10) (see under paragraph "FORWARD AND BACKWARD MOVEMENT”). 5. Pressing the accelerator pedal, the machine begins to proceed forward and to work according to the set functions. In order not to overload the brushes motor, it is convenient to reduce the brushes pressure going from smooth floors to rough ones (ex. concrete). The visualization of the blinking led (2) indicates an overload of the brushes motor. It is therefore necessary to reduce the pressure up to the level where the blinking warning stops. In manual mode every function of the machine has to be activated or deactivated manually. 15 ELECTRIC PROTECTION The machine is equipped with an electronic system of protection for all components that carry out functions of power or control. This device blocks the defective component and indicates on the display (1) the corresponding alarm from ”A1”, “A2” and on. To restore the functioning of the component, turn off and on again the machine acting upon the key switch. If the problem persists, please contact the authorized technical assistance. Starting again the cleaning operation: A. by pressing the push button (4) the automatic (AUTO) functioning is chosen to start working in automatic mode. B. by pressing the push button (3) the manual (MAN) functioning is chosen to start working in manual mode and all functions have to be re-established manually. OVERFLOW DEVICE In order to avoid serious damages to the suction motor, the machine is equipped with a mechanical float that intervenes when the recovery tank is full, closing the air flow of the suction. When this happens, it is necessary to empty the recovery tank (see under paragraph “RECOVERY TANK EMPTYING AND CLEANING”). AFTER CLEANING OPERATION IN AUTOMATIC OR MANUAL WORKING MODE: 1. A the end of the washing cycle, pressing the push button (1), the functioning of BREAK WASHING is chosen. When the signal lamp (2) is on, then the machine is in BREAK WASHING mode. In this way automatically the brushes lift, the solenoid valve shuts down and it is possible to finish the drying operation for a total time of about 15 seconds, afterwards also the squeegee is lifted and the suction stops. DAILY MAINTENANCE NOTE: all these phases are carried out with the machine operating, so that the squeegee can dry the interested cleaning area from the “drying phase of the brushes” and furthermore can dry the suction hose of its dirty water. At any time it is possible to interrupt the procedure BREAK WASHING by stopping the drive. 2. 2. 3. 4. 5. RECOVERY TANK EMPTYING AND CLEANING 1. 3. 4. 5. During the phase of BREAK WASHING, when the accelerator pedal is released for more than 3 seconds, the squeegee raises itself and the suction switches off automatically. After three seconds, the accelerator can be pressed again, if a machine's transfer has to be made (you can anyway make the transfer even if the pedal is not lifted once that 15 seconds have passed). Turn the switch key counterclockwise to switch off the machine. Insert the parking brake (see under paragraph “EMERGENCYPARKING BRAKE”). 6. The mode (BREAK WASHING) is specific for the transfer at the end of the cleaning operation. 16 Hold the exhaust hose (1) placed in the rear part of the machine after having taken it off from its fixing support. Take off the plug (2) from the exhaust hose acting upon its lever (3) and empty the recovery tank into appropriate containers, in compliance with the respective rules what the liquid disposal concerns. Take off the suction cover (4) after rotating the blocking levers (5). Take off the filter and the filter protection (6). Rinse the inside of the tank with a water jet through the hole become free of the filter. Reassemble all parts. BRUSHES CLEANING Disassemble the brushes and clean them with a water jet (for the brushes disassembly see under paragraph “BRUSHES DISASSEMBLY”). SQUEEGEE CLEANING Keeping the squeegee clean guarantees always the best drying result. For its cleaning it is necessary to: 1. Take off the squeegee hose (5) from the coupling. 2. Disassemble the squeegee (2) from its support (1) by loosening the knobs (4) counterclockwise and making slide the threaded parts in the appropriate slots up to their release. 3. Clean with care the internal part of the squeegee inlet eliminating eventual dirt residuals. 4. Clean with care the squeegee rubbers. 5. Reassemble all parts paying attention to put the washers (3) into position, they are two for each knob, so that they are assembled one under and the other on each of the two slots present on the support. SUCTION FILTER CLEANING 1. 2. 3. 4. 5. Take off suction cover (4) after rotating the blocking levers (5). Take off the filter (8) and its filter protection (6). Clean all parts with a water jet and especially the inside surfaces and the filter bottom. Carry out cleaning operations carefully. Reassemble all parts. WEEKLY MAINTENANCE REAR SQUEEGEE RUBBER CHECK BRUSHES DISASSEMBLY Check the squeegee rubber wear and eventually turn or replace it. For the replacement it is necessary to: 1. Lift the squeegee (see under paragraph “STOP OF THE MACHINE AFTER CLEANING OPERATION”). 2. Release the hook (1) of the rubber holder blade and take off the rubber. 3. Turn the rubber to a new side or replace it. To reassemble the squeegee repeat inversely the operations mentioned above, inserting the rubber on the guides and blocking it with the rubber holder blade. With the brushes base in lifted position (see under paragraph "BRUSHES ASSEMBLY"), rotate the brushes energically in order to release the button from the coupling spring until it becomes free and wash them with a water jet. The figure shows the rotating sense for brushes release. 17 SQUEEGEE “V” TYPE (OPTNIONAL) Alternatively to the standard squeegee, a “V”-shaped squeegee is available, especially indicated for floors with large joints. This squeegee is interchangeable with the standard one, same assembly on the machine, same adjustment in height, pressure and inclination. Different though are the methods in assembly and disassembly of the squeegee rubbers. CLEANING SOLUTION TANK AND OUTER FILTER 1. Bring the machine to an appropriate place for the detergent solution draining. 2. Unscrew the solution tank cap (1). 3. Unscrew the cap of the exhaust filter (2) and take off the filter. Be careful not to lose the gasket of the cap. 4. Open the solution valve (see under paragraph “FLOW ADJUSTMENT OF THE DETERGENT SOLUTION”), so that the detergent solution flows down into appropriate containers. 5. Rinse with a water jet the solution tank and the components of the filter. 6. Reassemble all parts. NOTE: in case of need it is possible to wash only the components of the outer solution filter as above-mentioned by closing the solution valve adjustment (see under paragraph “FLOW ADJUSTMENT OF THE DETERGENT SOLUTION”), so that the detergent solution remains in the solution tank. SQUEEGEE “V” (OPTNIONAL): REAR RUBBER REPLACEMENT Check the squeegee rubber wear and eventually turn or replace it. For the replacement it is necessary to: 1. Lift the squeegee (see under paragraph “STOP OF THE MACHINE AFTER CLEANING OPERATION”). 2. Unscrew the tie rods (1) on the terminals (2) of the rubber holder blade and disengage the terminals. 3. Unscrew the wing nuts (3) and take off the rubber holder blade (4). 4. Turn the rubber (5) to a new side or replace it.

The employed material and the bristles diameter are the elements that distinguish different types of brushes. MATERIAL CHARACTERISTICS PPL (Polypropylene) Good wear resistance. Maintains characteristics with hot water up to 50°C. It is not hygroscopic. NYLON Excellent wear resistance, even with hot water. It is hygroscopic. TYNEX Nylon bristles with grains of abrasive material. Use with caution in order not to mark the floor or ruin the polishing. BRISTLES THICKNESS Thicker bristles are more rigid and must be used on smooth floor or floor with small joints. On irregular floors with deep joints or relieves, it is recommended to use softer bristles which penetrate more easily and deeper. Please be aware that when brush bristles are worn out and therefore too small, they become rigid and unable to penetrate and clean deeper. This may also happen with thicker bristles creating brush vibration. PAD HOLDER It is equipped with anchor points which permit the blocking of the abrasive pad during work. The pad is recommended to clean smooth floors.
