If not, the packing can be disposed in accordance with current disposal laws.

4.4 LIFTING AND TRANSPORT: MACHINE,

BATTERY AND BATTERY CHARGER

( ! ) Never use a forklift truck to lift the machine. There are no places on the frame that can be used to lift the machine directly. Before preparing the packing and transporting the machine: - Empty the recovery tank and the detergent solu- tion tank. - Disassemble the squeegee and the brushes or scrapers. - Disconnect and remove the batteries. Place the machine on the original pallet (or an equivalent one that can bear the weight and is big enough for the machine’s overall dimensions) using an inclined surface. Solidly anchor the machine and the squeegee to the pallet using metallic brackets or other elements that can bear the weight of the parts. Lift the pallet with the machine and load it on the transport vehicle. Secure the machine and the pallet using ropes con- nected to the transport vehicle. As an alternative, when using private transport ve- hicles, use inclined ramps to push the machine without the pallet, making sure to protect all parts and the machine itself against violent impacts, hu- midity, vibrations and accidental movements dur- ing transport. The battery boxes have holes where tools can be hooked for handling.

) To lift or insert the battery (into the machine compartment), use only suitable personnel and equipment (cables, eyehooks, etc.) for the opera- tion and to bear the weight of the loads involved. When transporting, take the same precautions and follow the same instructions provided for the ma- chine together with those in the special manufac- turer’s manual. The battery charger can be transported on its sup- ports, both vertically and horizontally. Take the same precautions and follow the same instructions provided for the machine together with those in the special manufacturer’s manual.

5. INSTALLATION INFORMATION

5.1. BATTERY Regardless of the type of construction, battery per- formances are indicated with the term capacity, which always refers to a discharge period. Another important value is the number of possible dis- charges. The capacity is expressed in amps per hour (Ah), while the discharge period is generally indicated as 20 hours (C20 or 20h, or not expressly indicated) or 5 hours (C5 or 5h). The discharge/charge cycles indicate the number of times that the battery can hold a charge under the best conditions, i.e. they indicate the useful battery service life complying with all the necessary meas- ures. Therefore, the capacity of a battery varies depend- ing on how fast it uses energy (current). That’s why there’s such a variation in the capacity values ex- pressed as C5 or C20. These factors must be taken into account when comparing products available on the market with our own. This machine can be equipped with two types of batteries that differ in terms of their construction and features. - Pb-Acid battery with tubular armored modules: the electrolyte level in each element must be peri- odically checked! ( ! ) If one element is no longer covered by the acid solution it will oxidize in 24 hours, thus permanently affecting that element’s performance. () Refer to the battery manual to avoid physical damage and economic loss. - Gel module battery: this type of battery is main- tenance free and does not require special environ- ments for recharging (since it does not emit any harmful gases); therefore, it is highly recom- mended. ( ! ) It should not be taken for granted that batteries and battery chargers with the same technical features as those we offer will pro- duce the same results. Only perfect compat- ibility between these elements (Pb-Acid batteries, gel batteries and battery chargers) will safeguard the performances, the service life, the safety and the economic value in- vested.

) The technical features of the batteries used must match those indicated in the technical fea- tures section. Using different batteries may cause serious damage to the machine or may require them to be charged more frequently.

) During installation or when performing any type of battery maintenance, the operator must be equipped with adequate safety accessories to pre- vent accidents. Work far from open flames, do not short-circuit the battery poles, do not generate 31sparks and do not smoke. The batteries are normally supplied full of acid so- lution (for the Pb-Acid type) and ready for use. In any case, follow the steps indicated in the manual supplied with the battery and carefully follow the instructions regarding safety and operating proce- dures.

5.1.3 BATTERY INSTALLATION

To insert batteries in the battery compartment (Photo I - 2) it is necessary to lower the brush plate to the floor. To access to the battery compartment, pull the opening lever (Photo H - 1) and lift the recovery tank (Photo O - 3). Detach the spring clip (Photo I - 1) placed on the lifting cable of the brush plate. Place the batteries in the battery compartment (Photo I - 2) checking that they are in perfect con- ditions.

5.1.4 BATTERY CONNECTION

( ! ) These operations must be carried out by spe- cialized personnel. Install and charge the batteries in a dry ventilated place, far from sources of heat and corrosive sub- stances. Make sure that the voltage between the batteries and the battery charger corresponds. Pro- tect the circuit with a delay switch or a fuse with a higher charge than the maximum absorption of the battery charger. Comply with the polarity of the bat- tery plug. Disconnect the Anderson connector of the battery wiring from the Anderson connector of the machine wiring (Photo D - 7) (Photo F - 8) . Always hold the connectors with the hands and never pull on the cables. Photo G show connection diagram of the batteries for B - BT machines. () Attach the battery wiring to the battery, connecting the terminals only on the poles marked with the same symbol (red wiring “+”, black wiring “-“)! A battery short-circuit may cause an explo- sion! After checking that all the controls on the panel are in position “0” or at rest, connect the battery con- nector to the machine connector. ( ! ) Close the battery compartment making sure not to crush any wires. Photo I - 3 show the correct connection of the bat- teries for B - BT machines.

Connect the patch cord to the power cable of the battery charger ( Photo L - 2 ) and to the mains power. On switching on a new battery charger of the CBHD1 series, the charger will check the battery voltage and decide whether to start the charging process. If the battery is not connected to the bat- tery charger, the red LED will flash ( Photo M - 2 ). If the result of the test is positive after 1 second the charging of the battery can start, with the red LED on. The progress of the charging process is shown by three LED’s: red, yellow and green, as in the whole range of the battery chargers. The green LED ( Photo M - 3 ) shows the end of the charging or the last phase in case of deep charging process; in the former case, the relay is opened to disconnect galvanically the battery from the battery charger. ( ! ) For further information refer to the use and safety manual of the battery charger provided by the manufacturer. If the machine is equipped with Pb-Acid batter- ies, charge only in a well-ventilated area, lift the superior cover and open the battery plugs. () Follow the steps indicated in the battery man- ufacturer’s operating and safety manual (see the battery maintenance section). If the machine is equipped with GEL batteries (maintenance free), follow the instructions indi- cated here below. If the machine is used regularly: Always keep the batteries connected to the battery charger when the machine is not being used. If the machine is not used for extended time peri- ods: Charge the battery during the night after the last work period, and then disconnect the battery from the battery charger. Charge the battery during the night before using the machine again. Intermediate or incomplete charging while working should be avoided. If the machine is equipped with Pb-Acid batter- ies, use a hydrometer to check the element liquid intensity on a regular basis: if one or more ele- ments are discharged and the others fully charged, the battery has been damaged and should be re- placed or repaired (refer to the battery service manual). Close the element plugs and lower the superior cover.

To fill the tank: - Pour into the tank the required quantity of the chemical product, considering the percentage indi- cated by the supplier, with reference to the full tank capacity listed on the product sheet.

) Use only those products suitable for the floor and the dirt to be removed. - Pour water in the filling opening placed in the front of the machine ( Photo H - 2, O - 2 ). Leave 2 cm between the filling opening and the liq- uid level. Do not fill beyond this point!

) The machine was designed to be used with non-foaming and biodegradable deter- gents made specifically for scrubber-driers. The use of other chemical products (such as sodium hypochlorite, oxidizers, solvents or 37hydrocarbons) may damage or destroy the machine. - Follow the safety regulations specified in the rel- ative section and indicated on the detergent con- tainer. - Contact the machine manufacturer to obtain a complete list of available and suitable detergents. - Do not leave the water hose unattended and in- sert it completely into the tank: the hose might move and get sensitive parts of the machine wet. Close the tank with its foam plug. To drain the tank: - Unscrew and remove the transparent cap of filter /regulator of the cleaning solution placed in the bottom of the tank (Photo Q - 1) and wait for the complete emptying. - After draining, replace and tighten the cap.

6.10.1 ADJUSTING THE OUTFLOW OF THE

CLEANING SOLUTION The solution water filter (Photo Q - 1) also has the function as a regulator of the flow of the cleaning solution; screwing the transparent cover increases the amount of flow, while unscrewing the lid redu- ces the flow.

6.11 DRAINING THE RECOVERY TANK

The dirty water must be drained in accordance with national regulations. The user is completely responsible for ensuring compliance with such rules. After the detergent solution is finished, always empty the recovery tank ( Photo O - 3) before fill- ing it again. In general, the recovery tank can be emptied when- ever required, and even during intermediate phases of the work cycle. The recovery tank volume is higher than the deter- gent solution volume, therefore a potentially dan- gerous situation for the suction motor should never occur. In any case, a safety float ( Photo P - 1) will stop the suction if the dirty liquid level is too high.

) If water or foam starts leaking from under the tanks for any reason, immediately turn off the suc- tion motor and empty the recovery tank. To drain the tank: Drive the machine to a suitable location to drain the dirty water and preferably near a toilet or a sewer drain (comply with the national regulations for waste water disposal). Turn off the machine and remove the key from the panel. Detach the drain hose from the holder ( Photo B - 5, D - 6, F - 7 ) and, keeping it high, unscrew the plug. Lower the drain hose toward the selected drainage point. The emptying operation can be interrupted quickly and whenever required just by raising the drain hose. Check how much dirt is still in the tank and, if nec- essary, wash it inside through the inspection hole ( Photo P - 3). Fully tighten the drain hose with the screw plug and hang it on the support behind the machine. The drain hose plug must be airtight, otherwise the sub- sequent pressure loss will reduce drying efficiency.

The AC 230V model machine may be turned on only if the voltage indicated on the tag corresponds with the available voltage and that the electrical outlet is grounded (earthed). Do not damage the feed cable; do not crush or pull on it. Do not run over the feed cable with the machine. The cable could wind up in moving parts causing a short circuit. () ATTENTION !!! - The model AC 230V ma- chine has parts, which are connected to the current; contact with these could cause grave injuries or even death. - Before executing any type of operation on the ma- chine always disconnect it from the electrical source. - Never touch electric cables that are defective or worn. - Before gaining access to the electrical system it is always necessary to disconnect the machine from the electrical source. - In the case of defective, damaged, or cracked electric cables, replace immediately with authentic replacement parts. - The network of connections must be protected from water spray. - The patch cord for the connection of the machine to the mains power must conforms to current safety rules. - The electrical system to which the machine is con- nected must be equipped with a cutout box. - It is absolutely forbidden to use the machine in proximity to swimming pools or stretches of water.

) EMERGENCY SITUATIONS In case of emergency: - Immediately disconnect the machine from the power mains. - Immediately apply proper first-aid. If an accident should occur the machine must not be put into operation until a technician authorized by the manufacturer has examined it.

( ! ) Remember to lift the squeegee before driving reverse to avoid damaging it.

Remove any loose solid residue from the surface to be treated (using suitable tools, such as vacuum cleaners, sweepers, etc.). It this is not done, the solid dirt might prevent the squeegee from operat- ing correctly, reducing drying efficiency. Only trained personnel can drive this machine.

6.14.2 BATTERY CHARGE LEVEL CONTROLS

The sequence of lights of the battery charge control ( Photo C - 3, E - 1 ) progressively turns off until the battery is discharged . When the red light turns on ( Photo C - 3C, E - 1C ), turn off the brush motor, close the detergent solution outlet, finish drying the small residual moisture and go to the battery charg- ing area to charge the battery.

) The batteries may be irreparably dam- aged if the residual charge level drops too low (see the battery operating manual). Do not force the battery discharge beyond the safety limits, turning the key off and on or in any other manner.

Scrubbing and drying in a single pass. Prepare the machine as previously described and use it as described in paragraph 6.13. (☞) Never use the machine without the detergent solution: the floor might be damaged.

396.14.4 INDIRECT SCRUBBING OR FOR VERY

DIRTY SURFACES Scrubbing and drying in various passes. Prepare the machine as previously described. First set of operations: Wash the floor as described in paragraph 6.13, without drying the floor Allow the detergent solution to work on the dirty floor according to what is indicated in the information relative to the detergent used. Second set of operations: Proceed as explained in the previous “Direct Wash- ing” paragraph (6.14.3) to also proceed with drying the floor. (☞) Never use the machine without the detergent solution: the floor might be damaged.

6.14.5 POST-SCRUBBING OPERATIONS

Close the detergent solution outlet. Lift the brush unit and turn off the brush motor. After having completely dried any traces of water on the surface, wait a few seconds and then lift the squeegee and turn off the suction motor. Move to a suitable location to drain the tanks; empty and clean the tanks (as described in 6.11). Turn off the machine using the key and remove it from the control panel. If necessary, charge the battery (see the relative section).

) Turn the key, remove it from the control panel and disconnect the battery from the machine wiring.

) All work on the electrical system as well as all maintenance and repair operations (especially those not explicitly described in this manual) should be carried out only by authorized service centers or by specialized technical personnel who are experts in the sector and in the pertinent safety regulations. Performing regular maintenance on the machine, and carefully following the manufacturer’s instruc- tions, is the best guarantee for obtaining the best performances and extended machine service life.

Drain the two tanks as described in the relative sec- tions. Remove any solid dirt by filling and draining the tanks until all dirt has been eliminated: use a wash- ing hose or similar tool to do this.

) Water hotter than 50°, a high-pressure cleaner or excessively powerful sprays may damage the tanks and the machine. Leave the plugs of the tanks open (only while the machine is not being used) so that they can dry and thus prevent the formation of foul odors.

Detach the suction hose from the squeegee ( Photo N - 3). Now you can wash the hose and remove any ob- structions. Firmly insert the hose on the squeegee body.

( ! ) Do not handle the squeegee with bare hands: wear gloves and any safety clothing needed to carry out the operation. Detach the squeegee from the machine and clean it under running water using a sponge or a brush. Check the efficiency and the wear on the strips in contact with the floor. They are designed to scrape the film of detergent and water on the floor and to isolate that portion of the surface to enhance the vacuum of the suction motor: this ensures that the machine will dry very efficiently. Working constantly in this manner tends to round or to deteriorate the sharp edge of the strip, thus reducing drying effi- ciently. This is why the squeegee strips must be re- placed. To replace the worn blades, follow the instructions in the relative section. Turn the blades around to wear down the other sharp corners or to install new ones.

Remove and clean the brushes or the scraper disks. ( ! ) To avoid damaging the floor and the machine, carefully check if foreign matter, such as metallic parts, screws, chips, cords or similar items, has be- come jammed. Check that the brushes are flat as they work on the surface (check for any irregular wear on the brushes or on the abrasive disks). If necessary, ad- just the slant of the action on the floor. Use only the accessories recommended by the manufacturer: other products may reduce operat- ing safety.

Use a sponge or a soft cloth to clean the exterior of the machine and, if necessary, a soft brush to elim- inate tough dirt. The machine’s shockproof surface is rough to make it harder to see scratches caused during use. However, this does not make it easier to remove tough stains on the surface. It is prohibited to use steam machines, hoses with running water and high-pressure cleaners.

PB-Acid batteries Carry out maintenance operations in accordance with the manufacturer’s instructions and with all the 40other instructions provided in this manual. Exposing the element plates (not completely im- mersed in the acid solution) will lead to rapid oxi- dation and irreparably reduce the element’s operating capacities. An overflowing acid solution may corrode the ma- chine. Use battery chargers recommended by the manu- facturer and, in any case, those that are suitable for the type of battery to be charged. Always charge batteries in well-ventilated rooms: there is an explosion risk! The use of gel or maintenance-free batteries is highly recommended. GEL batteries Carry out maintenance operations in accordance with the manufacturer’s instructions and with all the other instructions provided in this manual. Use only those battery chargers recommended by the manufacturer.

7.7 THERMAL BREAKERS

The machine is equipped with electric protection devices on the main operating components to avoid costly malfunctions. Thermal breakers are installed to protect the drive motor wherever foreseen and the brush motor. When one of these breakers trips automatically, the disabled function can be reactivated by fully de- pressing the button of the breaker. When the thermal breakers trip, especially when the machine is used during the first few weeks, it might not be caused by actual machine malfunc- tions. However, a specialized technician should check the device if the relative breaker continues to trip.

7.8 PERIODIC MAINTENANCE

For all the operations described herein, refer to the instructions and detailed warnings in the relative sections.

7.8.1 DAILY OPERATIONS

Disassemble and check the brush or the pad driver disk (with the abrasive disks mounted). Check that there are no foreign bodies that may im- pede the movement or efficiency of all cleaning parts. Check the squeegee: clean the blades and check their condition/wear. If Pb-Acid batteries are used, carefully carry out the operations described by the battery manufacturer. Charge the batteries.

7.8.2 WEEKLY OPERATIONS

Check and, if necessary, replace the splash guard. Carefully check the profile of the squeegee blades and replace them, if necessary. Check that the suction hoses and conduits are not clogged; Thoroughly clean the solution and recovery tanks. For other models with the Pb-Acid battery: check the level of the electrolyte in all elements and, if necessary, top up with distilled water. Refer to the battery manufacturer’s detailed instructions. Lift the filter compartment cover and check under the impermeable sponge filter for any signs of liq- uid; if there is any, drain it off into the dirty water tank.

7.8.3 OPERATIONS AT EXTENDED INTER-

VALS Even though the machine was built with great pre- cision and conforms to the most severe quality tests, the electrical and mechanical parts will in- evitably be subjected to wear and aging after ex- tended periods of use. For safe and problem-free operation, your machine should be carefully checked every year by our au- thorized technical service centre (or by a specialist in the sector familiar with all the pertinent safety regulations contained in this manual). This type of work may have to be carried out more frequently if the machine operates in particular/dif- ficult situations and/or if required maintenance was not performed.
