1 Introduction Dear customer, Thank you for choosing our patient hoist aks-dualo. With your aks-dualo you have opted for a hoist which combines the two functions of lifting patients and assisting them to stand in one product. It guarantees you mobility, independence and consequently an improved quality of life. Alongside a high degree of safety, it offers care staff support when performing lifting and moving duties. The mature technology and the convenient configuration ensure safe use. The following basic features are what distinguish the aks-dualo: Optional configuration as standard hoist (for lifting) or active hoist (for assisting to stand) Electromotive lifting and/or standaid function Spreadable chassis legs to increase stability 24 V system with a removable battery pack Can be folded up The aks-patient hoist is available in the following versions: aks-dualo aks-mini dualo Where descriptions and handling instructions in this operating manual refer to all aksdualo versions, we only specify the name of the basic model aks-dualo. Where information is given which is specific to particular versions, these versions, e.g., aks-mini dualo are mentioned explicitly. Read and observe this operating manual before every use. The present operating manual provides you with the information which is important for safe use. Keep the operating manual in the vicinity of the aks-patient hoist so that it is available for reference at any time. Include this operating manual in the case of change of ownership of the aks patient hoist. Page 3

2 Intended purpose General The patient hoist aks-dualo is an active class I medical device according to the EU Council Directive 93/42/EEC, Appendix IX. It can be employed in all areas of care work and is intended for use by care staff properly instructed in its operation. It is intended for short-term use not involving contact with injured skin and requires the use of a suitable aks-hoist sling. The patient hoist lift aks-dualo may be used for patients weighing up to max. 150 kg. The patient aks-dualo is only suitable for driving short distances within the patient's flat or area of activity on one floor. It must only be used on an even, horizontal floor. The climatic conditions must be an ambient temperature of 0 C to 40 C, humidity of 20% to 80%, air pressure of 700 hpa to 1060 hpa and in the range of normally composed atmospheric air. It is permitted to be used in wet areas. For example, this includes the toilet or the bath. This does not include using the patient hoist under the shower. The aks-dualo is not explosion protected and is not permitted to be used in potentially explosive areas. Clinical pictures such as osteogenesis imperfecta, osteoporosis or spinal column damage, as well as mental disorientation or epileptic seizures can represent contraindications. The aks-dualo is only permitted to be used after careful consideration of the individual patient by the doctor and the care personnel. Standard hoist In the standard hoist version the aks-dualo is solely to be used for lifting and transferring a patient in a suitable aks-sling. This is usually performed with the patient in a seated position, although it may also be performed when the patient is in a lying position if an aks-spreader bar and aks-sling for transport in the lying position are employed. Patients can even be lifted off the floor. Active hoist In the active hoist version the aks-dualo is solely to be used to assist a patient from a seated position to a standing position and then transfer them in a suitable aks-sling. It serves as an aid to the natural movement of standing up and sitting down and can be driven with the patient standing aboard so that they may still go to the toilet independently for example. Additionally, the patient s participation stimulates his residual mobility by strengthening his circulation and musculature. The use of the active hoist requires the active participation of the patient. The ability to hold on to the lifting arm tightly is particularly important. Missing limbs or functional limitations of the musculoskeletal system (e.g., paraplegia) can limit or rule out the use of an active hoist. This must be decided by the operator on a case-by-case basis. Page 4

3 General safety instructions Read the operating manual completely before commissioning in order to avoid damage due to incorrect operation or hazards. It contains important information and instructions which are necessary for the proper operation of the aks patient hoist. The Medical Devices Operator Regulations are binding for the operator / user of medical devices. Only use the aks-patient hoist in accordance with the present operating manual. Keep the operating manual safe for possible reference. Ensure the proper, fault-free condition of the aks-patient hoist and its accessories before every use. Adjustments, exchanging the lifting arm and patient transport must only be performed by care staff instructed in these procedures. The assembly and the maintenance of the aks-patient hoist must only be performed by specialists who have the corresponding knowledge in accordance with the Medical Devices Operator Regulations. The activation time and the maximum load must not be exceeded, otherwise safe operation can no longer be guaranteed (see Chapter 21 Technical Data). Protect the aks-patient hoist from direct sunlight and heat. Ensure that no moisture enters the electrical system. Charge the batteries in a well-ventilated place. In the case of unusual noises, damage or malfunction, the aks-patient hoist must not be further operated. Observe the storage conditions in Chapter 14 Storage if the system is not to be used for a long period of time. Page 5

5.4 Functional description The aks-dualo is a mobile patient hoist with an electrical lifting and/or standaid function. It is fitted with lifting arms which can be removed without the need for tools and, depending on the application required, can be assembled as a standard hoist for lifting or an active hoist for assisting patients to stand. The U-shaped chassis is equipped with four castors, the rear two of which can be locked. The chassis legs can be spread by pressing a foot pedal. It may be necessary to adapt the chassis legs to the width of the place where the patient is sitting or to increase stability. A mast is mounted on the chassis. This can be folded forwards for transport or storage purposes. An ergonomic handle is attached to the mast to facilitate pushing of the patient hoist. In addition, the control unit and a removable battery pack can also be found on the side of the mast. The lifting arm holder is mounted on the top end of the mast. It can be adjusted using an electric lift motor. The standard lifting arm or active lifting arm respectively can be inserted into the lifting arm holder. The inserted lifting arm is secured with a socket pin to prevent its falling out. The inserted lifting arm is secured with a tube clip against falling out. The pin is attached to the lifting arm holder via a wire to ensure that is does not go missing. The standard lifting arms of the aks-dualo and aks-mini dualo versions are of different lengths. For safety reasons they are designed in such a way that it is not possible to insert them into the wrong hoist. Various aks spreader bars can be mounted on the standard lifting arm. These accept the different aks-slings. The active lifting arm has hooks on it, into which the slings can be hung directly. The aks-dualo active hoist also has a removable footboard with a height-adjustable shin pad affixed to the chassis. The footboard also has a holder for the standard lifting arm not currently in use. The electromotive height adjustment of the lifting arm is performed by a linear motor, which also features a manual emergency lowering. This is controlled using a manual control unit. The required electrical energy is provided by a high performance, removable 24 V battery pack attached to the control unit. This can either be charged on the hoist or using a separate wall charging station. Page 10

6 6.1 Assembly Locking plate The aks-patient hoist is equipped with universal bolts and locking plates at several places. These locking plates allow you to mount and remove individual components quickly and without the need for tools, particularly in so far as the assembly and folding away of the hoist is concerned and when mounting or exchanging spreader bars. The correct application and disengaging of the locking plate is described below. Locking plate Applying the locking plate Slide the locking plate into the groove at the end of the bolt (Figure 04). The curved end of the plate slips over the bevel of the bolt. The locking plate is correctly positioned when it clicks into place audibly and can be rotated freely in the bolt s groove. The incorrect and correct positions are shown in Figures 05 and 06 respectively. Universal bolt Figure 04 Incorrect Correct Figure 05 Figure 06 Disengaging the locking plate Retract the curved end of the plate slightly and slide the locking plate out of the bolt s groove (Figure 07). Figure 07 2 1 Page 11

Release the locking plate on the mast holder and pull the bolt out (Figure 09). Bolt with locking plate Figure 08 Figure 09 3. 4. Pull the mast upright (Figure 10). Reinsert the bolt into the mast holder in order to lock the mast in place. Secure the bolt with the locking plate (Figure 11). Bolt with locking plate Figure 10 Figure 11 5. 6. Remove the cable tie which holds together the lifting arm holder, the lift motor and the mast for safety reasons during transport. Disengage the locking plate on the upper motor retaining fork of the lifting arm holder and pull the universal bolt out. Page 12

7. Swing the lifting arm holder up and secure the lift motor with the universal bolt on the motor retaining fork (Figure 12). Secure the universal bolt with the locking plate (Figure 13). 1 Lifting arm holder Motor retaining fork 2 Universal bolt with locking plate Lift tube Figure 12 Figure 13 8. Now remove the tube clip from the lifting arm holder. First fold down the clamp on the tube clip (Figure 15). 9. 10. Insert the uncoated end of the standard lifting arm into the lifting arm holder as far as it will go. The lifting arm of the aks-dualo has been designed so that it only fits in the lifting arm holder when correctly orientated (Figure 14). Secure the standard lifting arm using the tube clip. Insert it as far as the stop and fold down the clamp (Figure 15). The tube clip is correctly attached if the clamp encircles the lifting arm tube (Figure 18). Figure 14 Standard lifting arm Lifting arm holder Note: If the tube clip cannot be inserted, this can be caused by the holes not being exactly on top of each other. Pull back the standard lifting arm somewhat until the holes are exactly on top of each other. Figure 15 Standard lifting arm Socket pin Page 13

6.3 Assembling the active hoist Steps 1 to 8 are the same for the assembly of the active hoist as they are for the standard hoist. 9. 10. Insert the uncoated end of the active lifting arm into the lifting arm holder as far as it will go (Figure 21). The lifting arm of the aks-dualo has been designed so that it only fits in the lifting arm holder when correctly orientated. Secure the active lifting arm with the socket pin (Figure 22). This is done by pressing the button and retaining it depressed whilst inserting the socket pin as far as it will go. The socket pin is in the correct position if the safety catches on the socket pin are visible on the opposite side (Figure 18). Active lifting arm Lifting arm holder Active lifting arm Socket pin Figure 21 Figure 22 Note: If it is not possible to insert the socket pin even though the button is depressed, it is likely that the holes are not correctly aligned. Retract the active lifting arm slightly until the holes are aligned exactly. The aks-patient hoist must only be operated with a correctly inserted socket pin! 11. Place the footboard on the crossmember of the chassis legs (Figure 23). Shin pad 12. Insert the shin pad into the holder tube on the footboard and secure it in place at the required height using the clamping lever (Figure 23). Clamping lever Footboard Figure 23 Page 15

8 8.1 Operation Parking brake The parking brakes are one of the important safety elements of an aks patient hoist. The rear castors are fitted with parking brakes which act directly on the wheels. To lock the castors, press the parking lever to the stop using your foot (Figure 28). The aks-patient hoist can no longer be pushed in this setting. To release the castors, press the parking lever pointing upwards (Figure 29). When locking the castors always ensure that both castors are locked! If only one castor is locked on a sloping floor, the unlocked wheel will roll downhill around the locked wheel. Depending on the slope of the surface, there is the danger that the aks patient hoist will tip over sideways. Locking lever Locking lever Castor locked Figure 28 Castor released Figure 29 Page 18

8.2 Spreader The chassis legs can be spread to increase stability during lifting and lowering. Press the right foot pedal down to spread the chassis legs (Figure 30). Press the left foot pedal down to return the chassis legs to their original parallel position (Figure 31). Moving the aks-patient hoist forwards and backwards gently makes it easier to spread the chassis legs. Ensure there is sufficient clearance from other objects when spreading the chassis legs. There must not be any objects or limbs located in the adjustment range. Foot pedal Foot pedal Figure 30 Figure 31 8.3 Emergency stop button The power supply to the motor of your aks-patient hoist is disconnected immediately by pressing the red emergency stop button on the control unit (Figure 32). This function enables you to avoid damage in emergencies. The button is unlocked again by turning it clockwise (direction of arrow). Figure 32 Emergency stop button Page 19

8.4 Mechanical emergency lowering The aks-patient hoist is equipped with mechanical emergency lowering in case of a defect in electrical parts or complete discharge of the battery pack. This is done by folding up the bar (Figure 33) at the fork head of the motor and turning the lift tube (as seen from above) clockwise. In this way, you lower the patient. 2 1 Bar Fork head Lift tube Figure 33 8.5 Manual control unit The manual control unit is used to control the lift motor. It is fitted with a rocker switch (Figure 34). Press the left side of the rocker switch (up arrow) to raise the lifting arm and the right side (down arrow) to lower it. Left switch: Raise lifting arm Right switch: Lower lifting arm 8.6 Batteries Figure 34 General The batteries used in the aks-patient hoists are lead gel batteries. These batteries must be permanently charged (similar to a car battery). There is no memory effect for the batteries. A deep discharge damages the batteries so severely that they become unusable. New, freshly charged batteries have a capacity of approx. 40 lifting cycles under full load. Attention: Always charge the batteries in a well ventilated place. Batteries must be completely charged before their first use. Connection Connect the mains battery charger (Figure 35) with the charging cable to the control unit (Figure 36) using the connection cable. Now plug the mains battery charger into a mains power socket with a connection value of 230 V / 50 Hz. Mains battery charger Connection cable Figure 35 Page 20

The aks-patient hoist does not function with a mains battery charger connected! For the charging, always connect the mains battery charger to the aks patient hoist first and not to the mains power supply until afterwards. Failure to observe can result in damage to the unit! After the charging, disconnect the mains battery charger from the mains power supply first and then from the aks patient hoist. Indicator lamps on the control unit Green LED The correct connection of the mains battery charger to the control unit is indicated by the green LED on the control unit (Figure 36). If the green LED does not light, there is no charging voltage present, i.e., the mains battery charger or the connection is defective. Yellow LED Yellow LED Green LED Charging cable The yellow LED indicates the charging process (Figure 36). It also lights every time the mains Figure 36 battery charger is connected. When the batteries are completely charged, the yellow LED goes out and the mains battery charger automatically switches to standby mode. If the battery capacity is less than a specified value after some time, the mains battery charge switches on again automatically and the yellow indicator lamp is lit again. If the batteries are almost fully charged, the yellow indicator may flash for a short time. This is not a fault. Charging time and capacity indicator lamp on the manual control unit The batteries of the aks-patient hoist should always be charged when not in use. Depending on the condition of the batteries, the charging process can take up to 24 hours, however 12 hours are usually sufficient. The batteries should be completely charged at least once per month in order to avoid a deep discharge, which can result in the destruction of the batteries. If the battery capacity drops below a minimum value, when the switch is pressed the capacity indicator lamp on the manual control unit (Figure 37) changes from green to red and a warning tone is given at the same time. In this case, the batteries must be charged immediately. Figure 37 Capacity indicator lamp (green / red) When red Page 21

When the green capacity indicator on the manual control unit is lit and the batteries are connected for charging, it only takes a few hours for the batteries to be fully charged again (fast charge). If the manual control unit indicator changes from green to red, the aks-patient hoist must not be operated further. A lifting cycle already started can, of course, be completed. Further operation in this condition (i.e., capacity indicator lamp lit red) results in a deep discharge and can thus result in damage to the batteries. If the batteries are now connected for charging, the charging voltage is reduced for the protection of the batteries. In this condition, the charging time is significantly increased (up to max. 3 days). If the batteries are not completely charged after 3 days, they are defective and must be replaced. Do not use the aks-patient hoist any more for lifting if the capacity control indicator is lit red or if a warning tone sounds during manual control. Failure to observe may damage the batteries. Removing and inserting the battery pack The battery pack on the aks-patient hoist can be removed without the need for tools. This gives you the possibility to exchange the battery pack quickly or charge it separately in a wall charging station. 1. 2. 3. Insert your fingers into the recessed grip on the battery pack from above and pull the unlocking lever upwards (Figure 38). Simultaneously pull the battery pack off the mounting rail and then upwards and out of the holder (Figure 38). To insert, repeat the process in the reverse order. Ensure that the unlocking lever clicks into place in the mounting rail and the battery pack lies securely flush to the mounting rail (Figure 39).

9 9.1 Patient transport Safety instructions Observe the following safety instructions before every lifting / assisting to stand and conveying of the patient: The member of care staff (user) must have the corresponding expert knowledge to select and use a suitable aks-sling. For use as a standard hoist, check the permissibility of the combination of spreader bar and sling before use based on the Table 04 in Chapter 10 Accessories/ Combinations. Check the correct sling size and sling form in relation to the patient. Check the safe condition of the sling before every use. The sling must have neither tears in the material nor damaged seams. Check whether the correct loop combination has been attached. All loops have 3 different mounting levels: long - medium - short. Each loop pair (e.g., leg loops, shoulder loops, etc.) must only show the following mounting combination: long - long, medium - medium or short - short. Check whether all loops are mounted in the hooks. Lock the wheels of the wheelchair, homecare bed, stretcher etc., in order to be able to raise and lower the patient safely. In doing so, leave the castors of the aks-patient hoist unbraked. Plan the patient transport to be as short as possible and never leave the patient unsupervised when suspended in the sling or positioned on the footboard. Supervise the patient during the transfer. Sharp movements of the patient or holding on to objects during the transfer can pose risks. Only lift the patient as high as is necessary. Ensure that the patient is positioned stably on the footboard when using the active hoist to assist him to stand and transport him. Employ a calf strap if necessary. Keep the hoist slings away from extreme heat and naked flames; they are not flame-retardent. Page 26

9.2 Patient transport with standard hoist In order to lift and convey a patient with the aks-dualo, it must be assembled as a standard hoist. Further prerequisites for this use are a suitable aks-spreader bar and suitable aks-sling. The type and size of the sling always depends on the stature of the patient and the type of use. aks provides several different spreader bars and a wide range of slings (see Chapter (10 Accessories/Combinations) which are adapted to the respective requirements. The attachment of an aks-standard sling (Figure 52) in combination with an aks-standard spreader bar on a patient in the lying position is described below. aks-standard sling Shoulder loop Manoeuvring handle Back panel of sling Leg strap Leg loop Figure 52 1. 2. 3. 4. 5. If the patient is lying on his back, roll him on to his side so that he is facing away from you. Fold the aks-standard sling in half down the middle. Place the aks-standard sling with the folded side down the back of the patient. When doing so, the aks logo and the labels must face downwards. Ensure that the bottom edge of the back panel of the sling reaches the coccyx and the top edge is at the patient's shoulders. Now roll the patient back over the aks-standard sling on to his other side. Now pull the folded half of the aks-standard sling under the patient and position it correctly. 6. 7. 8. Return the patient to his back. The patient is lying correctly on the aks-standard sling if his back is completely on the back panel of the sling and the leg straps are next to the thighs. Now raise the back part of the homecare bed until the patient is sitting almost upright. Page 27

9. 10. 11. 12. 13. 14. 15. Pass the leg straps from the outside to the inside around the patient's respective thighs. Position your aks-patient hoist with the aks-standard spreader bar so that the aks-standard spreader bar is at eye level in front of the patient. Ensure that the aks-standard spreader bar is not too close to the patient's face. Before attaching the sling to the spreader bar make sure that both the shoulder loops and both the leg loops are at the same height. Now hang both the shoulder loops on the outer hooks of the aks-standard spreader bar. Then hang both the leg loops crossed over on the inner hooks. Raise the lifting arm of the aks-patient hoist somewhat until the leg and shoulder loops become taut. Now check whether the aks-standard sling is attached correctly and comfortably. You can now lift the patient. Use the manoeuvring handle located on the top edge of the back panel of the sling for easier manoeuvring. 9.3 Patient transport with active hoist In order to assist a patient to stand and convey a patient with the aks-dualo, it must be assembled as an active hoist. A suitable aks-standaid sling is also needed for this application. The size of the sling always depends on the patient's stature. Attaching an aks-standaid sling with chest loop (Figure 53) in combination with the aks-calf strap and the bringing of a seated patient to a standing position from a chair are described below: aks standaid sling with chest loop Underarm padding Sling loop Chest loop Figure 53 Page 28

1. 2. 3. 4. 5. 6. 7. 8. 9. Undo the Velcro on the chest loop on the aks-standaid sling and place the sling behind the patient. The stuck-on aks logo must be visible on the outside from behind and the underarm pads must be nestled in the armpits. Close the chest loop over the patient's chest with the Velcro. Now spread the chassis legs of the akspatient hoist and position it in front of the patient. Ensure that the patient lifts his feet beforehand. The akspatient hoist is orientated correctly if Figure 54 the patient's feet are comfortably and completely positioned on the footplate of the footboard. Knee pad Calf strap (optional) Clamping lever Footplate Release the clamping lever on the shin pad and adjust the correct height of the shin pad (Figure 54). The top edge of the shin pad must be just below the patient's kneecaps. Undo the Velcro on the aks-calf strap and place this around the patient's calves. Close the Velcro again. Now lower the lifting arm if necessary and attach both sling loops of the aks-standaid sling to the hooks of the lifting arm. Raise the lifting arm of the aks-patient hoist somewhat until the sling loops become taut. Now check whether the aks-standaid sling is attached correctly and comfortably. The patient must now grasp the handles of the lifting arm tightly with both hands. You can now assist the patient to stand and transport him to the desired place. Page 29

11 Troubleshooting / fault clearance Should a fault occur and the aks-patient hoist no longer function, check the fault using Table 05. If the cause of the fault cannot be established and corrected, inform your aks authorised dealer. Table 05 Fault Possible causes Action Emergency stop button pressed Unlock emergency stop button Manual control unit cable not plugged in or plugged in Plug in manual control unit cable aks-patient hoist does not lift incorrectly (LED on the manual control unit does not light) aks-patient hoist does not lift (LED on the manual control unit lights green) aks-patient hoist does not lift Hoist connected to charger unit Battery pack discharged Battery pack defective Motor cable not plugged in or plugged in incorrectly Battery pack discharged Wait until the charging process is complete, then disconnect the charger unit from the hoist Charge battery pack Replace battery pack Plug in motor cable Charge battery pack (LED on the manual control lights red) Battery is not charged (green LED on the manual control does not light) Battery pack defective No correct connection between charging cable and mains battery charger Connection cable or mains battery charger defective Replace battery pack Check plug connections Replace defective part Page 32

12 Care / cleaning The aks-patient hoist can be cleaned manually using a damp cloth. Cleaning and care materials suitable for plastic furniture can be used as cleaning materials. Thereby, observe the following points: Do not use any abrasive agents or cleaning materials containing ammonium chloride. Only use dermatologically tested materials. Do not use any basic and alkaline cleaning agents. Do not use any aggressive cleaning agents (e.g., solvents) or hard brushes etc. Do not dip the electrical components in water; clean these with a barely damp cloth. Only use alcohol-free and chlorine-free disinfectants and methods from the RKI (Robert-Koch Institut) list or the disinfectants list of the VAH (Verbund für Angewandte Hygiene e.v.) for spraying and wiping disinfection. Observe the instructions and safety precautions from the manufacturers of the cleaning and disinfectant materials. Never clean the aks-patient hoist, especially the electrical system, with a high pressure cleaner, water hose or similar because doing so could damage the surfaces and seals, and water could enter. Page 33

13 When not in use If the aks-patient hoist is not needed, it should always be connected to the mains battery charger in order to ensure the full capacity of the batteries for the next use. The integrated charging electronics prevent overcharging of the batteries and switch to trickle charging when the batteries are completely charged. Always charge the batteries in a well ventilated place. 14 Storage Store the aks-patient hoist in as cool and dry a place as possible. The ambient conditions of the storage location should be at an ambient temperature of between 0 C and 40 C, humidity of between 20% and 80% and air pressure of between 700 hpa and 1060 hpa. Avoid direct sunlight. Use the original packaging for the storage. In the case of long periods of storage, it must be ensured that the batteries are completely charged at least once per month to avoid a possible deep discharge. A deep discharge results in destruction of the batteries. 15 Reuse The aks-dualo patient hoist is suitable for repeated use. The aks-patient hoist must be cleaned, disinfected and serviced according to Chapter 20 Maintenance at the very latest just before the reuse. Page 34

16 Service life The service life of the aks-patient hoist is largely dependent on the quantity of lifting procedures performed each day, the device s being used correctly and regular maintenance. The aks-patient hoist has been tested for long-term functional capacity with 11,000 lift procedures according to DIN EN ISO 10535. Please note that the factory warranty of your aks-patient hoist is valid for 24 months from the date of purchase (see Chapter 18 Guarantee). 17 Disposal If the aks-patient hoist has outlived its purpose, the electrical components must be treated as waste electrical equipment according to the WEEE Directive (Waste Electrical and Electronic Equipment) and disposed of properly. This is indicated by the symbol in Figure 55. In the case of electrical equipment brought into circulation as new equipment after 13/08/2005, the owner is legally obliged not to give their electrical components to municipal collecting points but to return them directly to the manufacturer. Our General Terms and Conditions are applicable for the return. Unusable batteries must not be disposed of in domestic waste. These must be disposed of in accordance with the regulations for the return and disposal of used batteries. The used plastic and metal parts of the aks-dualo must be disposed of separately and properly. Contact your local disposal company for this. Figure 55 Page 35

20 20.1 Maintenance General maintenance instructions The service life of the patient hoist is basically influenced by the handling. In order to ensure safe operation, a visual inspection and functional check according to the maintenance plan must be carried out at least annually by suitable qualified personnel. If the patient hoist is not regularly maintained properly, safe use is no longer guaranteed. Wear, damage or also loosening of connecting elements can thus not be detected. The Medical Products law (MPG) and the Medical Products Operator Regulations are applicable in Germany. The corresponding national requirements are applicable in other countries. EN 62353 in the respective current version must be used as test specification for this medical product. In the case of damage to load-bearing parts, electrical cables or parts of the electrical system, the patient hoist must no longer be used. Press the emergency stop button and remove the battery pack. In the case of damage and defects, inform your authorised dealer who will replace these parts. Connection or disconnection of electrical components must only be done when the power supply is disconnected. Press the emergency stop button for this. Only original aks spare parts and aks accessories which have been approved for this product are permitted to be used, otherwise any warranty and product liability are excluded. You must not make any technical modifications and additions without permission from aks. Page 37
