3.2 The user
Driving an electric wheelchair requires
cognitive, physical and visual skills. The
user must be able to estimate and
correct the results of actions when
operating the wheelchair.
The wheelchair can not transport more
than 1 person at a time. The maximum
user weight is 120 kg. unless otherwise
indicated on the identification plate.
Additional weight, such as rucksacks,
accessories or medical apparatus must
be added to the user’s weight to
determine the maximum weight, which
cannot be exceeded.
The user must be informed of the
contents of this user manual before
driving the wheelchair. In addition, the
user of the wheelchair must be given
thorough instruction by a qualified
specialist before he or she participates in
traffic. The first sessions in the
wheelchair should be practiced under
supervision of a trainer/advisor.
•The user of the wheelchair is at all
times completely responsible for
complying with the applicable
local safety regulations and
guidelines.
•If you are under the influence of
medicines that can have an effect
on your ability to drive, you are not
permitted to drive a wheelchair.
•Adequate vision is required in
order to safely operate a
wheelchair in the user situation
concerned.
•Not more than one person at a
time can be seated in the
wheelchair.
•Do not allow children to ride in the
wheelchair unsupervised.
3.3 User environment
This wheelchair has been designed to
accommodate both indoor and outdoor
use (EN12184 (2009) class B). When
driving the wheelchair outdoors, drive
only on paved roads, pavements,
footpaths and bicycle paths. The speed
must be adapted to suit the environment.
With all adjustment options set to neutral
(table 3.1), it can be assumed that when
using an RWD Liam, a slope of ≤10˚
belongs to a normal user environment
with no danger of instability. In the
technical specifications, you will find this
under ‘maximum safe slope’.
•Drive carefully on slippery roads
resulting from rain, ice or snow!
•Prevent the wheelchair from
coming into contact with sea
water: sea water is caustic and
may damage the wheelchair.
•Prevent the wheelchair from
coming into contact with sand:
sand can permeate into the
moving parts of the wheelchair,
causing extensive wear on these
parts.
•You are required to turn on the
lights in case of limited visibility.
•When driving at higher speeds you
must be extra careful. Select a
lower maximum speed indoors, on
the pavement and in pedestrian
areas.
•Do not drive off high obstacles.
•Do not use the wheelchair if
temperatures are below: -10˚C or
above +50˚C.
•Do not attach a weight to the
wheelchair without the approval of
a qualified specialist. This may
negatively affect the stability of the
product.
•Do not push and/or tow any
objects with the wheelchair.
•Do not open doors using the
legrests.
•Do not drive through puddles of
water.

10
4 Wheelchair settings
The average wheelchair user does not
exist. This is why Handicare wheelchairs
can be adjusted according to the specific
needs of the user.
In this, we make a distinction between
wheelchair settings and wheelchair
adjustment options. Settings are carried
out only once and must be executed by
qualified specialists, unless explicitly
stated otherwise. Adjustment options can
be carried out by the user. These
adjustment options do not require the
use of tools.
Only to be carried out by qualified
specialists.
Adjusting the seating system
The extensive settings with respect to
the seating system allow for optimum
support of the body. The following setting
options are possible:
Seating system 

QLASS
•Seat depth, Seat width
•Backrest angle
•Armrest height
•Lower leg length
4.1 Seat angle, seat height
Depending on the specific circumstances
of the user of the wheelchair the seat
height can be set. Every optional seat
height lays within the 10˚ (17,5%)
maximum safe slope according to
EN12184 (2009) ClassB. Lowering the
seat height has a positive influence on
the (dynamic) stability.
Enlarging the seat height has a negative
influence on the (dynamic) stability,
because the centre point of gravity gets
higher.
4.2 Height and depth of the
controller
See 

QLASS
4.3 Programme of the control
system
Only to be carried out by qualified
specialists. Incorrect setting of the
parameters of the control system could
lead to very dangerous situations.

11
5 Checking the wheelchair
before putting into use
Be careful! Check the following before
driving:
•Are the tyres sufficiently inflated (Ch.
8.3).
•Are the batteries sufficiently
charged? The green lights on the
battery indicator must be on. 


CONTROLLER
•Are the lights on the direction
indicators functioning properly? 


CONTROLLER
•Ensure that the free wheel switch has
been set to ‘drive’.
•When operating the wheelchair,
ensure that your clothing does not
hamper the wheelchair (i.e. too
long). Before use, always check if
your clothing or accessories do
not come into contact with the
wheels or and other moving and/or
rotating parts in which they could
become entangled.
•In winter, batteries have a reduced
capacity. During a period of light
frost, the capacity is roughly 75%
of the normal capacity. At
temperatures below -5˚C this will
be roughly 50%. This will reduce
your range of action.

12
6 Use of the wheelchair
6.1 Getting in and out of the
wheelchair
Getting in and out of a wheelchair is
sometimes called making a transfer.
Be careful! Before a transfer is made,
ensure that:
•The controller has been switched off


 CONTROLLER
•That the freewheel switch has been
switched to ‘drive’ (ch. 6.6)
•Do not stand on the foot-plates.
These have not been designed to
accommodate the full weight of a
person. In addition, this could cause
the wheelchair to topple over.
Forward transfer
1. Flip the footplates up (fig 6.1).
2. Swing the calf plates to the side (if
applicable) (fig 6.1).
3. If possible, swing the legrests to the
side (fig 6.2).
4. Seat yourself in the chair.
Sideways transfer
1. Push the lever to the back to unlock
the armrest (fig 6.3).
2. Take the armrest out (fig 6.3).
3. Seat yourself in the chair.

6.2 Driving the wheelchair
•As a wheelchair user, you are
vulnerable in traffic. Keep in mind
that other participants in traffic
may not always notice you. Keep
to the applicable traffic
regulations.
•Avoid out-of-the-way routes so
that help can be quickly on its way
when needed.
•Adapt your driving style and speed
to the circumstances.
Electric wheelchairs are driven by means
of a controller. The controller has its own
user manual 

 CONTROLLER , which
has been included with this wheelchair.
•Switch on the controller 


CONTROLLER
•Set the maximum speed limit 


CONTROLLER
•Move the joystick into the direction
you would like to go
•Moving the joystick even further
forwards will cause the wheelchair to
move faster
Curves
•Never take curves at full speed.
Decrease your speed before taking a
curve.
•Use the indicators when changing
direction.
Braking/Emergency stop
To brake, the joystick must be moved
into the neutral position or released
completely. The wheelchair will brake
automatically. An emergency stop can
also be made by releasing the joystick.
An emergency stop can be made by
releasing the joystick. The following
should be avoided when driving:
•Do not push the on/off button
•Do not move suddenly in the
opposite direction. The wheelchair
will come to an abrupt standstill
with a sudden jolt. Not only is this
uncomfortable, it could lead to
tipping over if you are on a slope.
6.3 Driving on a slope
With all adjustment options set to the
neutral position (table 3.1), it can be
assumed that when using an RWD Liam,
a grade of ≤10˚ (17,5%) belongs to a
normal user environment with no danger
of instability. In the technical
specifications, you will find this under
‘maximum safe slope’.
Slopes steeper than the normal user
environment
Driving on slopes whose grade is
steeper than the maximum safety limit
can lead to safety risks with respect to
stability. This requires great care and
complete control of the user. Always
drive carefully and never take
unnecessary risks! Follow the
instructions next to the warnings
carefully!
The stability and performance of a
wheelchair depend on a number of
variables. Wheelchairs are adapted
according to the needs of individual
users. This is why variables will differ
from wheelchair to wheelchair. Ask your
dealer to inform you about the
instructions for use and the specific
settings and adjustments that can
influence the driving characteristics of
the wheelchair.

14
Driving on a slope
•When driving on a slope, always
drive carefully and with the utmost
concentration.
•Avoid sudden and jerky
movements.
•Avoid making emergency stops on
a slope.
•Avoid changing direction on a
slope whenever possible.
•Do not turn on a slope.
•Only drive up a slope with all the
adjustment options set to the
neutral position.
•Driving on a slope in reverse can
be extremely dangerous.
•Do not drive on slopes with loose
gravel or a sandy surface, as one
of the driving wheels could
slip/spin.
•Driving on a slope too long can
cause overheating of the motor.
Uphill
•If you notice a strong decrease in
speed when driving up a slope,
take a less steep route.
Downhill
•Prevent the wheelchair from
gaining too much speed.
6.4 Obstakels
Driving up a kerb
•Choose the place where the kerb is
at its lowest (see chapter 10 ‘climbing
capacity for obstacles’)
•Drive straight up to the kerb (20 cm in
front of the kerb).
•Move the joystick forwards. Drive up
the kerb without changing direction.
•As soon as the front wheels are on
the pavement, you must maintain
speed in order to get onto the
pavement with all wheels. If it is
impossible to drive onto the
pavement, find a lower place where it
is possible.
Driving down a kerb
•Choose the place where the kerb is
at its lowest. In case of doubt, do not
take any risks and find another route
or someone to help you.
•Drive with your front wheels straight
up to the kerb.
•Move the joystick slowly forwards.
Drive down the kerb carefully and as
slowly as possible, without changing
direction.
•Never drive down stairs in a
wheelchair.
•Do not drive off obstacles higher
than 6 cm.

15
6.5 Adjustment options
Adjustment options are those parts of a
wheelchair that can be adjusted by the
user without the use of tools. The Liam
can be ordered with the following
adjustment options:
Mechanical adjustment options
•Backrest recline 

LIAM SEATING
•Headrest 

LIAM SEATING
6.6 Freewheel switch: pushing
the wheelchair
The wheelchair can also be moved by
pushing. For this purpose, the motors
must be disengaged. This is done with a
freewheel switch; one for each motor.
The freewheel switch can be set to two
positions:
•‘Drive’ mode. In this position, the
chair can not be pushed (a in figure
6.5).
•‘Push’ mode. In this position, the
chair can not be driven using the
controller (b in figure 6.5).
Figuur 6.5
The automatic parking brake only works
if the switch is set to the ‘drive’ position.
The freewheel switch should only be set
to ‘push’ if the chair is to be pushed.
When the chair is no longer being
pushed, the freewheel switch should be
set to 'drive' immediately.
•The freewheel switch is a function
that was developed especially for
wheelchair attendants. The
freewheel switch should only be
operated by the attendant and
never by the user.
•Never set the switch to ‘push’ on a
slope! When the freewheel switch
is set to ‘push’, the automatic
parking brake will be deactivated.
The wheelchair could then move
down the slope.
6.7 Storage after use
If the wheelchair is not in use, it must be
stored in a cool place without being
exposed to extreme weather conditions.
Do not place the wheelchair in direct
sunlight. Parts of the wheelchair can
become so hot that they could cause
burns. The surrounding temperature
when stored may not be lower than 20˚C
or higher than +65˚C.

16
7 Transport of the
wheelchair
7.1 Transporting the wheelchair
Power wheelchairs are very heavy to lift.
Use suitable ramps to wheel the chair in
and out of the vehicle. Once the
wheelchair is in the vehicle, it must be
secured with an ISO 10542 approved tie-
down system that is suited to the weight
of that particular wheelchair. The
wheelchair can only be fastened by
securing it to the tie-down points on the
wheelchair’s frame (fig. 7.1).
The total weight of the wheelchair
depends on its composition. The
technical specifications (Ch. 10) give
insight in several optional items and how
they influence the total weight. Always
weigh the total weight of the wheelchair
to be certain that the correct fastening
system is used.
•Position the wheelchair in the car
never in another way than facing
front wards.
•Use an ISO 10542 approved
attachment system suitable for the
total weight of the wheelchair to
secure the wheelchair.
•The wheelchair can only be fastened
by securing it to the tie-down points
on the wheelchair’s frame (fig. 7.1).
The wheelchair may not be secured
onto any accessories (wishbones,
armrests, anti-tip brackets etc.).
•Use all 4 tie-down points (fig. 7.1).
•Make sure that the freewheel levers
are set to ‘drive’ (fig. 6.5).
•It’s not allowed to alter the tie-down
points on the frame without
permission of Handicare.
•If the wheelchair is involved in an
accident it needs to be checked and
approved by a Handicare expert
before it will be used again.
•Only use GEL or AGM batteries.
Figure 7.1
7.2 Transport of the wheelchair
(no occupant)
When the wheelchair is transported
without an occupant, remove the parts
that can be taken away.

of space in the vehicle 

LIAM SEATING

17
7.3 The wheelchair as seat in a
vehicle
The Liam is successfully crash tested
according to ISO 7176-19. Even so, a
wheelchair is not designed as a car seat
and cannot offer the same degree of
safety that is offered by standard car
seats. Handicare recommends that
wheelchair users transfer to a regular car
seat if possible.
It’s not possible for every wheelchair
user to make a transfer. To optimize the
safety of the wheelchair user and other
passengers in the vehicle. Follow all the
instructions and warnings carefully!
•Always ask for confirmation of the
transporter that the vehicle is
suitably designed, insured and
equipped to transport a person a
person in a wheelchair.
Fixating the wheelchair
•To tie down the wheelchair for
transport in the vehicle, follow the
instructions of chapter 7.1.
•When the wheelchair is equipped
with a table top this needs to be
removed during transport. Store
these parts securely.
•All adjustment options of the
seating system need to be in the
‘neutral’ position (Ch. 3.4).
•Handicare recommends that the
wheelchair is always equipped
with a headrest and that this is
used during transport when the
wheelchair is used as a carseat.
•Any accessories on the wheelchair
need to be removed and need to
be stored securily..
7.4 Securing the occupant
•Use a three-point occupant
restraint system to secure the
occupant of the wheelchair on the
pelvis/hips and shoulder. This
three-point safety belt must be
secured to the roof and the floor of
the vehicle (fig.7.2).
•Position the belt across the hips
as tightly as possible at an angle
between 30°and 75°.
•The other part of the belt is
positioned to sit across the chest
and shoulder (fig. 7.2).
•The seat belt should fit as tightly
as possible and must not be
twisted.
•Ensure that the seat belt is not
obstructed from having contact
with the body by wheelchair parts,
such as armrests or wheels.
•When the wheelchair is equipped
with positioning belts: these
should nerver be used as safety
belts.
•Care should be taken when
applying the occupant restraint to
position the seatbelt buckle so
that the release button will not be
contacted by wheelchair
components during crash.

Tabel 7.1: Onderhoud van de rolstoel
8.1 Cleaning the wheelchair
To clean the seating system, we refer to
the user manual for the seating system


LIAM SEATING .
•Ensure that the controller is
switched off during cleaning. If the
joystick is accidently touched, the
wheelchair can move and the
electrical options used
accidentally.
•Be careful with water in view of the
electronic system.
Removing dry dirt
First, wipe the dirty parts with a wet
sponge. Use preferably clean water or
soft soapy water. Wipe the parts dry with
a soft dry cloth.
•Never use abrasive or aggressive
cleaning agents. They can scratch
the wheelchair.
•Do not use organic solvents such
as thinner, benzene or white spirit.
•Never use a high pressure cleaner
for cleaning the wheelchair.

20
8.2 Batteries
The wheelchair uses ‘dry’ gel batteries.
These batteries are completely closed
and maintenance free.
•The use of ‘wet’ batteries is not
permitted.
•In winter, batteries have a reduced
capacity. During a period of light
frost, the capacity is roughly 75%
of the normal capacity. At
temperatures below -5˚C this will
be roughly 50%. This will reduce
your range of action.
Charging the batteries
Check the manual of the battery charger
to see if it’s suitable for the type of used
batteries. Check chapter 10 for the
technical specifications.
•First, switch off the wheelchair’s
controller.
•Put the charge plug of the battery
charger in the charge connector of
the controller 

 CONTROLLER
•Activate the battery charger. This
depends on the type of battery
charger. Consult the user manual of
your battery charger.
If the wheelchair is not being used, we
recommend charging the batteries via
the battery charger. For normal use, the
batteries should be charged every night.
The battery charger’s display will indicate
when the batteries have been fully
charged. Depending on how depleted
the batteries are, it may take up to 12
hours before the batteries are once
again fully charged.
NB: It takes about 15 full charging cycli
before the batteries reach their full
capacity.
Maintaining the batteries
Ensure that the batteries are always fully
charged. Not using the batteries for a
long period of time can damage them.
Do not use the wheelchair if the batteries
are almost depleted and never
completely deplete the batteries. This
can seriously damage the batteries and
you may run the risk of coming to an
unintended standstill.
Replacing the batteries
If the capacity of the batteries is
continually decreasing so that the
wheelchair can only be used for short
trips, this will mean that the batteries are
the end of their lifespan. The batteries
will then need to be replaced. Please
contact your dealer for assistance.
•Batteries contain acids. Damaged
batteries can cause severe danger
to your health. Follow the
instructions on the batteries at all
times.
