7 Wheelchair adjustments
Wheelchair adjustments are those components that the user can adjust without
the use of tools. The wheelchair may be fitted with powered and/ or mechanical
adjustment options.
Warning
P The centre of gravity and the static and dynamic stability is affected, when
adjustments on the wheelchair are made. Therefore adjustments should only be
made when the wheelchair is on a flat surface.
P Powered adjustments involve parts of the wheelchair moving and/or rotating.
Contact with such moving parts may result in serious physical injury or damage
to the wheelchair. You should avoid any contact with the moving parts of the
wheelchair.
P When adjustments are made, the standard size of the wheelchair increases.
Make sure that the wheelchair does not block any escape routes.
P Use the seat tilt only when the back angle is vertical. P With electrically
activated seat tilt or electrical back angle adjustment, should
only be driven short distances in the home area. Therefore use always the slow
driving profile. Note that the viewing area is limited with activated seat
tilt or electrical back. P When driving, keep the backrest as straight as
possible, with a maximum of 10 ° deviation from the vertical. For the seat
plane angle, this deviation is a maximum of 4 ° with respect to the neutral
position. This ensures that your field of vision is not restricted and your
reflectors are clearly visible.

8.1. Checking the wheelchair
Warning
Carry out the following checks before using the wheelchair: P Check whether
the tyres are sufficiently inflated (see 10.6). P Ensure that the freewheel
switch is in the “Drive” position (see 8.6).
CONTROLLER Check that the batteries are sufficiently charged and that the
green lights on the battery indicator are on.
CONTROLLER Check whether the lights and the indicators are working.
Warning
When using the wheelchair: P Take the length of your clothing into account.
Before using the wheelchair,
check to see whether any garments or accessories could come into contact with
the wheels or any other moving and/or rotating parts and become entangled in
them. P Battery capacity is reduced in winter. When there is a light frost,
capacity is around 75% of normal capacity. At temperatures below -5°C,
capacity is reduced by approximately 50%. This reduces the operating range.
8.2. Getting into and out of the wheelchair
Getting into and out of a wheelchair is also described as making a transfer.
Warning
Do not stand on the footplates during a 29
transfer. They are not designed to carry a person’s full weight. Standing on
them may also cause the wheelchair to tip over. Before making a transfer,
ensure that: P The controller is turned off P The freewheel switch is in the

8.3. Driving the wheelchair
CONTROLLER A controller is used for driving a powered wheelchair. There is a
separate manual for the controller and this is supplied with the wheelchair.
Read through all the user manuals carefully before using the wheelchair for
the first time. The information they contain is essential for the safe use and
proper maintenance (cleaning). If any of the manuals are missing on delivery
of your wheelchair, please contact your dealer immediately.
Warning
P As a wheelchair user, you are vulnerable when on the road. Remember that
other road users may not always notice you.
P Observe traffic regulations. P Stop using the wheelchair immediately if the
wheelchair shows any unusual or
unexpected behavior and let the wheelchair check by an authorized dealer. P
Avoid taking any deserted routes so that help is always on hand in any
emergency situation. P Adjust your speed and driving style to the conditions.
P To stop or to make an emergency stop, move the joystick to the neutral
position or let go of it. The wheelchair will then brake automatically. P
Never take corners at full speed. Reduce your speed when cornering. P Use the
indicators when changing direction.
When driving: P Do not press the on/off button. P DIETZ recommends wearing a
lap belt, as electric wheelchairs can suddenly
stop moving during operation for various reasons. P Do not suddenly start
driving in the opposite direction. If you do, the
wheelchair will stop abruptly and jolt. This is not only unpleasant, it can
also lead to the wheelchair tipping over.

8.4. Driving on slopes or ramps 31
With all settings in the neutral position (see 7.1), slopes/ramps of 6° (10.5%) are deemed to be part of the standard user environment for the RWD without stability being affected (Fig. 31).
Slopes or ramps outside the standard user environment Driving on slopes/ramps that are steeper than the maximum safe slope may lead to safety risks in terms of stability. Driving on such slopes/ramps requires the user to practise extreme caution and full control. Always drive carefully and never experiment! Follow the instructions given under warnings!
6°
The stability and performance of the wheelchair depend on many variables. Wheelchairs are adapted to individual users. For this reason these variables will be different from one wheelchair to another. You should therefore ensure that your dealer provides you with sufficient information about how to use the wheelchair and that the dealer informs you whether the specific adjustments or adaptations for your situation will affect the handling of the wheelchair.
Warning
P Always drive up and down slopes/ramps slowly, concentrating on what you are
doing.
P Avoid any sudden, jolting movements. P Avoid making an emergency stop on a
slope/ramp. P The braking distance on a slope can be considerably greater than
on a flat
surface. P When on slopes/ramp, try to avoid changing direction as much as
possible. P Do not turn on a slope. P Drive on slopes/ramps only when all
adjustments (lift, tilt, recline) are in the
neutral position. P Never drive up or down a slope/ramp backwards. P Do not
drive on slopes/ramp with loose gravel or a sandy surface, as one of the
drive wheels may slip or spin. P Driving up or down a slope for long periods
of time may result in the motor
overheating. P If you notice that your speed is being greatly reduced when
driving up a slope,
select a route that is less steep. P Prevent the wheelchair from reaching high
speeds when driving down slopes.

10.4. Cleaning the wheelchair and its upholstery
Warning
P When cleaning the wheelchair, ensure that the controller is turned off. If
the joystick is accidently touched, this may cause the wheelchair to start
moving or the powered options to be operated.
P Take care when using water because of the system being electronic. P Clean
the upholstery and the dirty parts of the wheelchair using a damp cloth
and household soap. Then rub dry using a soft, dry cloth. P Never use abrasive
or aggressive detergents, as these may scratch surfaces. P Do not use any
organic solvents, such as thinner, benzine or white spirit. P Do not
chemically clean the upholstery. P Do not iron or spin-dry the upholstery.
10.5. Batteries
The wheelchair is fitted with “dry” gel batteries. The batteries are fully
sealed and require no maintenance.
Warning
P The use of “wet” batteries is not permitted. P Battery capacity is reduced
in winter. When there is a light frost, capacity
is around 75% of normal capacity. At temperatures below -5°C, capacity is
reduced by approximately 50%. This reduces the operating range. P Ensure that
the batteries are always well charged. Long-term non-usage of the batteries
can damage them. P Do not use the wheelchair if the batteries are almost flat
and never drive until the batteries are completely flat. Doing so can
seriously damage them and you would also mean running the risk of coming to a
standstill. P The batteries contain gel. Damaged batteries pose a serious
threat to health. Always follow the instructions on the batteries.
Charging
Technical specifications (see 11).
CHARGER To check if the charger is suitable for use with the wheelchair
batteries and for instructions on how to activate the battery charger.
CONTROLLER For the right connection for the charger plug.
The contents of the manuals are vital in terms of the safe use of the
wheelchair. If any of the manuals are missing on delivery of your wheelchair,
please contact your dealer immediately.
Under normal use, the batteries will need to be charged every night. The
battery charger indicates when the batteries are fully charged. Depending on
how flat the batteries are, it can take up to 12 hours to fully charge them.
MINKO – 35
10 Servicing / maintenance
Replacement If the battery capacity is steadily decreasing and the wheelchair
can only be used for very short trips, this means that the batteries have
reached the end of their lifespan. They then need to be replaced. Consult your
dealer.
10.6. Tyres
In order to ensure optimum performance of your wheelchair, it is very
important to keep its tyres at the right pressure. The correct pressure can
also be found on the side of the tyres.
Wheel
8″ castor wheel 9″ castor wheel 10″ castor wheel 12″ drive wheel 14″ drive
wheel
Maximum tyre pressure 2,5 bar 3,5 bar 3,5 bar 2,8 bar 3,5 bar
Warning
Never exceed the maximum tyre pressure.
If tyres are too soft, the handling of the wheelchair will be reduced.
Propelling the wheelchair will also require more energy, resulting in a
greater drain on the batteries. Driving with soft tyres also unnecessarily
increases tyre wear.
Warning
SERVICE Detailed information on tire repair (qualified specialists only).
Before starting any repair work on the tyres, first fully deflate them.
10.7. Re-use
The power wheelchair is ideal for use as a loaned wheelchair or for short-term
use. The number of times it can be reused depends on the material wear
conditions and the functional capabilities of the respective product. If the
wheelchair is passed on to a new user or specialist dealer for reuse, please
remember to hand over all technical documents that are necessary for safe
usage.
The wheelchair must be cleaned and disinfected, and must be checked for damage
and approved by the specialist retailer. To do so, please check all the
inspection points listed in the maintenance schedule on the wheelchair (see
10.2). For disinfection spray or wipe all parts of the whellchair thoroughly
with an alcohol-based surface disinfectant for medical devices (maximum 70%
propyalcohol).
36 – MINKO
10 Servicing / maintenance Observe the use and processing instructions issued
by the cleaning agent/ disinfectant manufacturer. Safe disinfection cannot be
guaranteed on upholstery parts featuring seams and textiles. In this case we
recommend to replace these parts.
10.8. Lifetime
The technical lifetime of the wheelchair is influenced by the extent to which
it is used. Under normal use and with the prescribed maintenance, the expected
technical lifetime of the wheelchair is approximately five years. In order to
derive maximum benefit from the lifetime of the wheelchair, ensure that it
undergoes regular maintenance (see 10).
10.9. Disposing of the wheelchair
If your wheelchair is no longer required or needs to be replaced, it will
usually be possible to arrange for your dealer to take it back. If this should
not be possible, consult with your local authority to find out if it can be
recycled or if the materials used in it can be processed in an environmentally
friendly way. Various plastics and metals were used in the manufacture of the
wheelchair. It also contains electronic components that should be disposed of
appropriately. The batteries constitute chemical waste.
