2. Getting started
This section is primarily aimed at you as a user of the device. It describes how to prepare
the device for use, adjust the seat height, charge electric models, and how to create good
conditions when moving. For care instructions, see 3. Caring for the device.
If you have any questions about your device or if something unexpected has happened, please
first contact your prescriber or dealer. You can find up-to-date contact details in Section 1.1.
Contact details. You are also welcome to contact us at Mercado Medic.
2.1. Before use
The device is always supplied with a seat,
backrest, armrest and brake. When delivered
from Mercado Medic, the backrest and brake
lever are not yet fitted. These should always
be fitted before the device is first used.
Brake lever
Insert the brake lever into the brake lever
bracket (A), see Figure 2.1. The brake lever
can be placed on the right or left side.
Backrest mechanism
Place the backrest support posts in the
backrest mechanism (B) and set the desired
height level, see Figure 2.1. Tighten all
controls (B).
Armrests
Loosen the armrest controls (C) and set the
desired height and width levels, see Figure
2.1. Tighten all controls (C).
Neck support
If the device is supplied with a neck support,
insert the neck support mechanism into the
backrest bracket (D) and set the desired
height level, see Figure 2.1. Tighten all
controls (D).
Battery
Before first use, the battery in electric
models must be activated and charged. This
is done by connecting the battery charger
to the device's charging socket and to a
wall outlet (E), see Figure 2.1. The charging
socket can be placed in different places
on the device. The most common is that
the device comes with the charging socket
mounted at the rear edge of the left armrest.
Wait until the battery is fully charged before
using the device. This normally takes 2 to 5
hours. When the battery is fully charged, the
LED on the charger lights up green. For other
charging instructions, see 2.3. Charging.

• The device must not be moved when the
seat is in the raised position.
• Emergency stop for control buttons:
If, for whatever reason, the system
does not interrupt a movement after
the corresponding control button has
been released, the movement can be
interrupted by pressing the button for
movement in another direction.
• Emergency stop for hand-held controller:
If, for whatever reason, the system
does not interrupt a movement after
the corresponding control button has
been released, the movement can be
interrupted by pressing any of the other
buttons on the hand-held controller.
• Button lock on hand-held controller:
To enable or disable the button lock
for a function, press and hold both of
the directional buttons of the relevant
function for at least three seconds.
The button lock locks only the current
function. To lock multiple functions, each
function must be locked separately.
Warning! As a user, you should
contact your prescriber, technical
aids centre or distributor if the
device shows reduced or altered
performance. A device showing a
loss of or change in performance
must immediately be taken out of
use in order to avoid an accident.
The device must not be used again
until an authorised technician has
examined the device.
Warning! To maintain safety, the
device should only be used by the
person and purpose for which it is
intended. The device is set up for a
single user. Changing settings may
affect the user's seating position,
which may result in damage or injury.
Warning! You are not permitted to
modify the device yourself. If you
would like individual customisation,
contact your prescriber or distributor.
If the device is modified, the CE
marking no longer applies and
Mercado Medic may no longer have
full device liability. Modifications
may affect the safety of the device
and lead to accidents.
Warning! The device may be
equipped with long cables or
wires that cannot be secured in
order for the device to function
properly. Cables and wires can pose
strangulation risks to small children,
for example. Do not leave the device
unattended with small children
nearby.
Warning! The device is equipped
with small parts such as screws that
can come loose. Small parts that
have come loose can pose choking
hazards for children and pets.
Warning! Metal surfaces may
become very hot if they are exposed
to direct sunlight. Skin contact with
hot surfaces can lead to burns. Avoid
exposing metal surfaces to direct
sunlight.
Warning! Always ensure that the
device’s brake is applied when
sitting down and getting up. If the
device is not braked, it risks rolling
away when you get up or sit down,
which can lead to fall injuries.

Instruction manual for the use of medical bariatric work chairs Getting started
21-08861-UK-01
2.2. Electrical and manual height
adjustment
Depending on the model, the device has
electric or manual height adjustment.
Electric height adjustment is controlled by
the hand-held controller or by the control
button located under the right armrest,
see Figure 2.2. Manual height adjustment
is controlled by controls placed under the
seat or under the right armrest, see Figure
2.3. See 5. Configurations and settings for
detailed information about all the features
and controls of the device.
2.3. Charging
For electric models, the battery should
be charged once a day. Fully charging the
battery on a daily basis will take 2 to 5 hours.
It is important that the battery is never
completely discharged, as this helps to
prolong the life of the battery. Daily charging
of the battery is especially important on the
configurations that have an electric brake, to
ensure that, as a user, you can always get in
and out of the device safely. The device emits
a low battery level warning sound, for both
low and critical. Low battery is indicated by a
short signal. Critical battery level is indicated
by a short signal that ends with a loud beep.
If the device is equipped with a hand-held
controller, the battery level can also be
determined by checking the indicator lights,
see Figure 2.4.
The device must be charged in a safe manner.
The electrical functions cannot be used
when the device is charging. For this reason,
choose an easily accessible wall socket to
plug the charger into. The charger cable to the
wall socket is 1 metre long and must not be
extended. In case of emergency, disconnect
the device from the mains by unplugging the
charger from the wall socket.
Figure 2.3. Controls on the manual model.
Figure 2.2. Controls on the electric model.
Figure 2.4. Battery level indicator on hand-held controller.

10
Instruction manual for the use of medical bariatric work chairs Getting started
21-08861-UK-01
How to charge the device
1. Connect the charger plug into the charging
socket, see Figure 2.5. The charging
socket is normally located at the rear
edge of the left armrest, but can also be
located under the seat, for example.
2. Connect the charger plug into the wall
socket. The LED on the charger will
indicate that charging is underway.
3. The battery is fully charged when the
LED on the charger changes colour from
red to green. If you are using the hand-
held controller, this will also be indicated
by the three green battery LEDs on the
controller, which will start to flash at the
same time.
If the electrical functions have not been
used for 7 days, the battery switches off
automatically. To reconnect the battery,
connect the battery charger to the charging
socket and the wall outlet and wait at least
5 seconds before unplugging the charger. It
is recommended to charge the battery fully
after the battery has been disconnected.
If no electrical functions are working, try
charging the battery. If electrical functions
still do not work, contact your prescriber or
distributor, see 1.1. Contact details.
2.4. Transfers
When moving around while sitting in the
device, it is important to make good contact
with the floor. For example, rubber-soled
indoor shoes can provide better grip and thus
facilitate movement. Rugs and carpets make
the movement more difficult. It is therefore
recommended to remove rugs or carpets if
you want to move while sitting.
Do not sit on the product when crossing
thresholds, mouldings and gaps.
Warning! Always ensure that the
device’s brake is applied when
sitting down and getting up. If the
device is not braked, it risks rolling
away when you get up or sit down,
which can lead to fall injuries.
Figure 2.5. Connecting the plug to the charging
socket under the armrest.

3. Caring for the device
Clean the device in accordance with the instructions in this section in order to maintain
functions and service life. If you still have issues that cannot be resolved using available home
resources, please contact your prescriber or distributor for reconditioning.
PLEASE NOTE! Do not wash the device with water or other liquids and chemicals.
3.1. Padded parts
To maintain good device hygiene, the device’s
padded parts should be cleaned regularly.
Ifpadded parts are not regularly cleaned, the
device may require reconditioning.
Plush padded parts
Use a foam cleaner to clean plush padded
parts. Start by removing any loose debris.
Then use a cloth to distribute a thin layer of
foam. Wipe with a clean, damp cloth. Finish by
vacuuming the upholstery after it has dried.
Synthetic leather padded parts
Use soap and water or surface disinfectant
to clean synthetic leather padded parts.
Start by removing any loose debris. Then
use a cloth to clean the upholstery with soap
and water or surface disinfectant. If the
upholstery is cleaned using soap and water,
finish by wiping with a clean, damp cloth.
Leather padded parts
Use water to clean leather padded parts.
Start by removing any loose debris. Then
clean the upholstery with a clean, damp
cloth. For best effect, padded parts should
be cleaned immediately after something
is spilled on it. To extend the service life
of padded parts, avoid direct contact with
chemicals or prolonged sunlight.
3.2. Castors and brake feet
Regular cleaning of castors and brake feet
is required to maintain the operation of the
device. Wipe castors and brake feet with
a damp cloth. Remove any hair from the
castors using a thin crochet needle or similar
implement.
3.3. Other parts
Do not clean lifting devices and actuators on
any electric brake installed on the device, see
Figure 3.1. This is because there is a risk that
the grease required for these mechanisms
to function as intended might be removed
during cleaning.
If necessary, a dry cloth can be used to
remove dust from any electronic parts of
the device. Clean the other non-electronic
parts of the device once a week or when
