Page 5: Safety
2 Safety Observe the following guidelines for maintenance or repair work: Danger! Use caution near flammables or especially when holding lit cigarettes. The back upholstery and seat cushion may catch fire. Danger! When getting into or out of the wheelchair with power add-on drive, the electronic control must be switched off. Danger! When using lifting platforms, be sure that the wheelchair is standing centrically on the lifting platform area and that none of the wheelchair‘s components, such as the anti-tipper, are protruding into the danger area. Danger! Explosive gases can develop while the batteries are charging. For this reason, provide for sufficient ventilation when using the battery charger in closed rooms. Do not smoke when near the battery charger or handling the batteries. Avoid fire and sparks! Danger! When mounting the z50 wheel or manual wheelchair wheel, make sure before driving that the locking mechanism has engaged (see sections ‘Assembly of the z50 Wheel’ and ‘Assembly of the Manual Wheelchair Wheel’ in the Instructions for Use). Attention! After cleaning the z50 power add-on drive check its operating performance. Attention! Driving over a longer period of time with only 2 LEDs of the battery indicator lit will result in battery discharge. To avoid function failure and permanent damage, charge the battery of the z50 power add-on drive immediately. Attention! To avoid overheating the battery charger, make sure that the cooling ribs or vent slots are uncovered. Attention! To prevent uncontrolled driving through accidental joystick manipulation, switch off the wheelchair when nobody is using it or the driving function is not required. Attention! Do not use the footplates when getting into or out of the wheelchair. Attention! Never use a water hose or high-pressure cleaning apparatus for cleaning the wheelchair. - Page 6 Note!

Page 10: Battery Packs / Fuse
5.2 Battery Pack / Fuse Battery The z50 standard equipment includes a 2 Ah gel battery pack. A 6 Ah gel battery pack is available as an option. Except for battery charging, these battery packs do not require servicing. For installation of the battery case, first connect the battery cable plug into the battery case's receptacle and lock and engage the plug by rotating it to the right. Put the battery case into the carrying bag and secure with hook and loop flap. To disconnect the battery cable, slide the silver locking pin slightly to the rear and rotate the plug to the left until it reaches the stop. Remove the plug from the battery case to separate the battery from the wheelchair. Battery Charging The remaining battery capacity determines the distance range of the z50 power add-on drive. Many factors have an influence on the battery's capacity. Besides the ambient temperature, the age of the batteries and the time and extent of driving, the way you charge the batteries has considerable effects on the capacity and thus on the distance range. Driving over a longer period of time with only the red LEDs of the battery indicator lit will result in battery discharge and thus battery damage. In addition, there is the risk that the z50 may stop due to zero battery capacity and put the user in a dangerous situation. If the z50 is not used for a longer period of time, a charging cycle should be carried out once a week to maintain the battery's capacity. Note: The warranty is void in case of damages that result from a totally discharged battery. When the z50 is not used over extended periods of time it must be charged once a week. Only use the battery charger provided by Otto Bock. The indications on the type plate of the battery charger must be identical to the voltage of the mains supply of your country. Charging will start automatically. The current charging state is indicated by the LEDs of the battery charger. - Page 11 Battery charger . ON/OFF indicator 2. Charging indicator 3.

Solution: Check the mains cable and socket. Error 7: Battery fault. Solution: Battery replacement recommended. The battery charger features a programmed recharging phase. Once a discharged battery is completely charged, the battery charger can remain connected with no risk of damaging the battery. Before the z50 can be used, the wheelchair control must be switched off and on. Danger! Explosive gases can develop while batteries are charging. For this reason, provide for sufficient ventilation when using the battery charger in closed rooms. Do not smoke when near the battery charger or handling the batteries. Avoid fire and sparks! Attention! To avoid overheating the battery charger, make sure that the cooling ribs or vent slots are uncovered. The battery charger should only be used within the indicated ranges of temperature and humidity. Make sure that the rubber feet of the battery charger stand on level ground. When the battery charger is in use, it must be protected from direct sunlight, since this would additionally heat up the charger. Avoid dust and dirt from affecting the function of the battery charger. To clean the charger, use a dry cloth.
- Page 13 To charge the battery, plug the 3-pole plug into the charging receptacle of the z50. The charging receptacle is located on the underside of the control panel. The battery case is attached to the wheelchair frame with a special bag. Depending on the mounting position, the bag is attached in front or behind the crossbrace. The size of the battery bag depends on battery size (2 Ah or 6 Ah). For detailed instructions on the battery bag attachment, see technical data tables. The bag is provided with altogether eleven hook and loop flaps, allowing the bag position to be set individually. Four flaps are located on each the left and right side of the bag and are hung on the upper and lower frame tubes. The three last flaps are located on the rear side of the bag and are hung on the crossbrace tubes, thus increasing the stability of the bag. First attach the adhesive strips with hook surface Then attach the flaps and tighten them. for hook and loop connection to the frame in the Finally attach the flaps on the rear side of the bag spacing for the flaps.
