2. 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 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
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
recognise unsafe behaviour.
• Unauthorised persons.
Anybody who is authorised 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 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.
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 centre of gravity of
the hoist patient unit. On the other hand,
if the wheels are locked, the patient will
be dragged to the centre of gravity of
the hoist patient unit, which will result in
discomfort.

Making cutting-edge medical equipment affordable PAGE 05
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 behaviour 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,
immobilisation equipment and any other
specific measures.
2. When and for what purpose the patient
should be immobilised 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 immobilise a
patient, closely following the instructions
and advice provided by the manufacturer.
4. How a patient should be monitored or
immobilised, 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 is not interfered
when combined with other medical devices
that also comply with the electromagnetic
standards.
Some apparatus, particularly older devices,
that do not comply with electromagnetic
compatibility standards may, however, cause
or 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 authorised, qualified
personnel.

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).
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.
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 rayas will remain fixed
and then turn off.
Do not disconnect the charger plug by
pulling the cable as it could be damaged.

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.
