Safety precautions

Any person using or assembling these items must first read and understand the assembly, operating, and cleaning instructions provided. Read all safety information contained in this manual (highlighted with the symbol ) carefully. Failure to follow these instructions may result in damage to property and/or personal injury.
2.1 Recommendations
Familiarise yourself with the safety controls and devices before operating the hoist. Use a sling that is CE marked and check that its size and other characteristics are appropriate to the patient. Do not use a sling that is frayed or worn, and always follow the instructions provided with it.
Check that the combined weight of the patient and the sling does not exceed the maximum working load displayed on the hoist. Preferably, the patient should be as close to the floor as possible prior to transferring him or her.
A loaded hoist should always be used on flat, smooth surfaces that are free of obstacles. If moving a patient along a sloping surface, the gradient must not be greater than 5° and it is recommended to use the assistance of a helper. Never leave a hoist loaded with a patient on a sloping surface. Transfer the patient with the hoist legs in a parallel position at a  maximum speed of 3 km/h (0.8 m/s). Keep the hoist away from water, humidity, splashes, and corrosive atmospheres (indoor swimming pools, the sea, etc.). Do not use the electric hoist in the shower or recharge the battery in the bathroom.
Do not force the safety controls and devices. Do not push the mast, the boom or the patient to move the hoist.
2.2 Braking and moving
**While the hoist is stationary, the brakes should always be on, except when lifting or lowering a patient. If the wheels are free to rotate during these operations, the hoist will find the center of gravity of the hoist patient unit. On the other hand, if the wheels are locked, the patient will be dragged to the center of gravity of the hoist patient unit, which will result in discomfort.
2.3 Before moving a patient
**Consider individual hazards, including:

• Risk of crushing/squeezing.
• Potential falls.
• Disturbed patients.
• Patients with learning difficulties.
• Small children and pregnant women.
• Persons without the mental capacity to recognize unsafe behavior.
• Unauthorized persons.

Anybody who is authorized to use the hoist must be able to do so in a safe and controlled way.
**Due to the continuous, smooth lifting action of the moving parts, there is a risk of entrapment. When operating these parts, the user and/or the carer must make sure that there are no body parts in the areas where they may become trapped.
2.4 Identifying risk patients**
The following recommendations are aimed at care personnel to help reduce the specific risks that may affect certain patients. These hazards are listed in a number of reports drawn up by national government agencies with recommendations to reduce them.
It is recommended to establish a patient admission procedure that enables identifying risk profiles and applying measures suited to the health condition and behavior of such patients. Risk profiles include:

• Elderly and/or disabled patients.
• Patients with dementia, mental illness, hydrocephaly or disorientation.
• Agitated and/or aggressive patients. The measures tested and approved include establishing a protocol with the following points:

1. When and for what purpose the hoist may be used, as well as the type of sling, immobilization equipment, and any other specific measures.
2. When and for what purpose the patient should be immobilized or the use of other means to reduce the risk of falls is required (e.g. laying foam on the floor).
3. If special means are used to immobilize a patient, closely follow the instructions and advice provided by the manufacturer.
4. How a patient should be monitored or immobilized, including during intervals.

2.5 Electrical safety precautions
All the hoist’s electrical connections must comply with the International Electrotechnical Commission (IEC) standards. The power supply should be equipped with an earth leakage circuit breaker with a maximum operating current of 30 mA, as prescribed by standard IEC 364-5-53.
This product complies with the standards EN 60601-1 and EN 60601-1-2 on electrical apparatus and the electromagnetic interference of medical devices. Therefore, it does not interfere or does not interfere when combined with other medical devices that also comply with electromagnetic standards.
Some apparatus, particularly older devices, that do not comply with electromagnetic compatibility standards may, however, causer be affected by interference when used with this hoist. If using such apparatus, you must make sure that any potential malfunction will not harm the patient or any other person.
****Before moving the hoist, make sure the power supply cable is unplugged from the mains. Any work on electrical parts may only be undertaken by authorized, qualified personnel.

Assembly

**No tools are necessary to assemble the hoist, although some parts are considerably heavy. It is therefore advisable to use the assistance of a helper when handling such parts. Pay attention to avoid being knocked or trapped.

3.2 Joining the pre-assembled structures
Carefully remove the packaging.
Place the base structure on the floor with the brakes on the rear wheels (3). Remove the locking knob (15)(B), DON’T REMOVE THE GREY PLASTIC PIECES OF THE MAST BASE, and insert the mast-boom structure in the mast base (1). Align the holes in the mast (6) and base and put the locking knob (15)(B) back in place, making sure it is tight and secure.
Check with the buttons (H) that the legs open and close normally and that the wheels rotate correctly. Check that the spreader bar rotates and swings freely and is firmly stened to the arm.

4. Operating Instructions (see images on page 08)

4.1 Spreading and narrowing the legs
To open/close the legs you have to use the lower buttons of the control box or the control (H), which activate the motors (Q). These two motors work simultaneously using a Y-type cable(P). To transfer patients and/or pass between doors or through narrow corridors it is recommended that the legs are closed.
4.2 Lifting and lowering
Use the top buttons (G) on the box or control for lifting or lowering the hoist arm. During the descent or hoisting of the patient, it is recommended that the wheels are not braked. In this way, the patient-hoist assembly will look for the center of gravity avoiding discomfort to the patient.
When the arm reaches its lower or upper limit it stops automatically.
It is advisable to avoid repeatedly pressing the buttons (G-H), since the successive start-ups of the motor consume more battery, reducing its useful life.
The computer goes into standby mode if no button is pressed. To reactivate it, press any button.
4.3 Emergency stop and safety lowering
The electrical equipment has a red emergency stop button (F). With the button released the battery is ready to work. With the button pressed the battery does not act. To release, the button must be rotated clockwise and released. In case of battery failure, the actuator has a manual emergency descent system. To do this, the red wheel (E) of the actuator must be pressed down, while turning clockwise to slowly descend the patient.
4.4 Recharging the battery
During hoisting or descent, the load state pilots (I) of both the load base and the command are illuminated. Two green pilots indicate capacity between 66-100%, 1 green pilot indicates capacity between 33-66% and 1 orange pilot indicates capacity less than 33%).
The system emits an acoustic warning when the battery is about to run out, allowing several complete cycles to be performed. If you only have a removable battery and a charging base you must bring the hoist to a power outlet and connect the cable to the charging base (N) and then connect to the network (220V-240V).
**While the battery is being recharged the hoist motor is not working, the emergency stop should not be pressed and the pilot (I) of the control box and the control light up. The stripes of the battery flash. When it is fully charged the 3 rays will remain fixed and then turn off.
Do not disconnect the charger plug by pulling the cable as it could be damaged.
If you use the hoist daily it is recommended to recharge the battery at night. The charger does not allow the battery to be overloaded. If you are not going to use the hoist for a long time it is advisable to recharge the battery at least every three months so that it is in its optimal state of use.
If you have an additional charging base (on request) you can recharge the battery by removing it from the charging base installed on the hoist and placing it in an additional charging base (O) installed next to a power outlet.
4.5 Changing the battery
To remove the battery, hold it by the top handle (J) and release the metal guide from the control box holder. To place it back in the charging dock, rest the battery in the charging dock and insert the guide again until you hear a “click”.
4.6 Overload
The control box stops working if the actuator is overloaded (due to excess load or excess continuous operating time). It will work again after a few minutes when the overload has been removed. Duty cycle approx.: 2 minutes in continuous use and 18 minutes in rest.
4.6 Improper use**
Improper use of this hoist may cause injury to users and/or deteriorate equipment, in addition to invalidating the product warranty. Examples:

• Use by a person who has not read this manual or who has not been trained by an authorized team member.
• Use of the hoist, functions, accessories, or movement of the hoist by persons not qualified to use it safely.
