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 EC 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 5o
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.
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.
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
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.

3.2 Joining the
pre-assembled structures
Place the base structure on the floor with the
brakes on the rear wheels (3) on. Remove
the locking knob (14), 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 (14) back
in place, making sure it is tight and secure.
Check that the legs (4) open and close
correctly and that the wheels rotate freely.
The actuator (10) is supplied and mounted
on the hoist in the factory. If you need to
disassemble the actuator, loosen the ring (a)
securing the pin (b). To reassemble do the
opposite operation. (Picture 2)
Connect FIRMLY the hand control plug (c)
and the actuator jack (d) to the bottom of the

4. Operating
instructions
4.1 Spreading and narrowing
the legs
The hoist’s legs can be narrowed or spread
to allow access to a wheelchair. To spread
the legs, step on the left pedal (2). To narrow
the legs, step on the right pedal. While
transferring patients and to negotiate doors
and confined corridors, the legs should
preferably be narrowed.
4.2 Lifting and lowering
Lifting and lowering the patient is achieved
by the electric actuator’s action on the
hoist boom. These movements are easy to
control using the two buttons (up and down)
provided on the hand control. When the
boom reaches the upper or lower limit of its
run, it stops automatically. (Picture 4)
4.3 Emergency stop and
safety lowering
The electrical system includes a red
emergency stop button. When the red button
is in the out position, the battery will operate
normally. When the red button is depressed,
the power from the battery is cut off.
To reset the button to the out position, turn it
clockwise and release. (Picture 5)
The actuator is equipped with a quick release
device that allows lowering the patient
manually in the event of battery failure. To do
this, rotate the grey collar clockwise. The
patient will be lowered slowly. (Picture 6)
4.4 Braking and moving
When lifting or lowering a patient, it is
recommended to press and hold the
relevant button. Repeatedly pressing
and releasing the buttons will cause the
actuator motor to start and stop each time,
using more battery and shortening
its operating lifetime.
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.

4.5 Recharging the battery
If you only have one removable battery and
one charging base, place the hoist near an
electric socket, connect the power supply
cable to the charging base and plug into the
mains. While the battery is charging the
actuator fails, the emergency stop should
not be pressed and green LEDs “on” and
orange “charge” light. When fully charged
the orange LED “charge” will turn off. The
green light “on” will remain on until you
disconnect from the network.
If you have an extra charging base, you can
remove the battery from the charging base
mounted on the hoist and charge it using the
extra charging base, suitably located near a
mains electricity socket. (Picture 8)
4.6 Changing the battery
4.7 Overload
Control box beeps twice if the actuator is
overloaded (above the current limit), it will
cut the current and the actuator will stop.
The actuator can be started again when the
overload is removed.
If the hoist is used daily, it is recommended
to recharge the battery during the night.
The charger will not allow the battery to
overcharge.
When not using the hoist, it is
recommended to recharge the battery at
least once every three months to ensure it
is always in good working condition.
Do not disconnect the black charger
jack plug by pulling the cable. When not
recharging the battery, it is recommended
to keep the mains cable plugged into
the charging base to prevent any liquids
accidentally entering the socket.
(Picture 7)
To remove the battery from the charging
base, hold the upper handle, press and
remove carefully off its support. To place
the battery back in the charging base, slide
it on position, join the upper handle on the
support until you hear a click. (Picture 9)
