04-4.9.5 B REPLACEMENT OF BATTERIES 3 4
04- REPLACEMENT OF BATTERIES B 4.9.5 WARNING! The charger must be disconnected from the supply mains when removing the battery. NO TOOLS NEEDED! REPLACE/CONNECT The batteries are placed inside the battery cases. NOTE! Never remove the battery from the battery case. The method of replacing batteries is to first disconnect the wires connecting the batteries to the cleaner. This is done by twisting and then pulling the clamping circuit until the wires from the cleaner are separated from the wires to the batteries. Then remove the battery case from belt. This is done by lifting up the flap and pushing the button on the backside of the battery case so that the case is separated from the belt. TEST AFTER REPLACEMENT After repair, please check that the vacuum cleaner is functioning to Nilfisk specifications and to any local authorised precautions. NOTE! NEVER REMOVE THE BATTERY FROM THE BATTERY CASE. Refit new batteries in reversed order. SCRAPPING OF BATTERIES The batteries must be removed from the appliance before the appliance is scrapped. The battery is to be disposed of safely and in accordance with all locally approved precautions and environmental regulations. Recycle packing material and all assemblies according to local regulations. DISPOSAL OF BATTERIES Return batteries to a disposal plant. If the batteries are leaking, return batteries to a disposal plant or a similar local facility. Any leakage from the batteries can be removed with household paper. Leaking batteries and fouled household paper should be placed in a sealed plastic bag and then handled according to all locally approved precautions and environmental regulations. If leakage from the batteries has been in contact with skin, eyes or clothes - remove battery leakage with water.

04- CHARGING OF BATTERIES B 4.9.5 4 BEFORE CHARGING First disconnect the wires connecting the batteries to the cleaner. This is done by twisting and then pulling the clamping circuit until the wires from the cleaner are separated from the wires to the batteries. Then remove the battery case from belt. This is done by lifting up the flap and pushing the button on the backside of the battery case so that the case is separated from the belt. Battery packs should be used and charged together as a set. Do not mix battery packs. Do not take the battery packs out of their battery case. No battery maintenance is required. The battery packs should not be altered in any way. Use and store the battery packs indoors and in a dry environment. Operating temperature is 3 F to 04 F (0 C to 40 C) and storage temperature is 5 F to F (-5 C to 50 C). Battery life will be reduced if exposed to extreme temperatures, over 40 F (over 60 C). Do not unplug the battery packs from the machine or charger by pulling on the cord. To unplug, grasp the plugs, not the cord. Do not drop the battery packs. If the battery packs appears faulty, has been dropped, damaged, left outdoors or has been exposed to water, return it to an authorized service center. Let the battery pack completely discharge every 0th cycle as a minimum, by running the machine until the machine automatically stops because of low voltage. THE CARGER The Backuum Battery / Acro-Batt is supplied with a fully automatic charger. After the battery packs have discharged from use they can be connected to the charger. The charger will automatically begin charging when the proper temperature, 3 F to 04 F (0 C to 40 C), is reached. The LEDs on the charger will blink (Green LED) rapidly when the batteries are ready for use (95% charged) and blink slowly when the batteries are completely charged (00%). When the battery packs are fully charged the charger will automatically switch into trickle charge mode and will not overcharge the batteries. Charger should be located in an area with adequate ventilation. CHARGER LED STATUS TABLE CHARGING OF BATTERIES The machine is equipped with low voltage sensor and a high temperature sensor. The machine will not operate if the battery packs are too hot or if a low voltage condition exists. Battery packs should be used and charged together as a set. Do not mix battery packs if using more than sets of battery packs. It is a good idea to mark the sets. After the battery packs have discharged from use they can be connected to the charger. The charger will automatically begin charging when the proper temperature, 3 F to 04 F (0 C to 40 C), is reached. Do not disconnect battery packs from charger while charger is running. To obtain full run time from the battery packs after charging the temperature must cool to approximately 04 F (40 C). This typically takes 0,5 hour at room temperature. If the battery packs are connected before they are cooled down, run time will be reduced due to the temperature sensor within the machine.
