Mika is primarily intended as a wheelchair to be pushed, but it is also
suitable for independent operation. Taking into account the instructions
for use and the individual‘s skills and knowledge, the decision about
independent operation and the routes to be travelled is at the discretion of
the user or the caregiver.
The specialist dealer will provide information about the various
adjustment possibilities of the mobility base and about the eects on the
driving behaviour.
4.1 GENERAL DRIVING CHARACTERISTICS
When sitting down and standing up from the mobility base, do
not step on what you think are steps (e.g. footplate) - there is a
risk of tipping over! Only get on and o the mobility base with
the parking brake applied, on rm, lever ground.
Before each use, check the rm attachment of the seat shell.
Do not hang any objects on the push handle or back - danger of
tipping over!
Never reach between the spokes while using the wheelchair.
Always apply the brake on both sides. Do not put weight on the
brake lever. Before each ride, check the condition of the wheels
and the proper functioning of the brakes.
On unpaved ground (gravel, mud, water, ice etc.), there is limited
manoeuvrability and a risk of tipping or sliding.
Danger of tipping over due to changes in the ground condition
(subsoil, edge, slope, weather etc.).
Avoid dangerous paths, e.g. steep slopes, downhill sections,
narrow paths, etc.
A sudden push can cause the unit to tip over.
Extreme adjustments and unfavourable body posture, e.g. leaning
out too far, increase the risk of tipping over.
If the front cators are wobbling, reduce the driving speed.
The mobility base may only be driven on public roads if you have
experience in driving. The mobility base may only be driven
where pedestrian trac is permitted. When participating in
public road trac, equip the device with reectors. The road
trac regulations must be observed.
Secure the mobility base against rolling away by applying the
parking brake.
4.2 BALANCING TIPS
Changes in the centre of gravity always aect the behaviour of the
mobility base. The centre of gravity can be inuenced by changing
the body posture as well as by changing the equipment settings (the
inuence of the equipment settings on the centre of gravity is described
in the corresponding section).
The use of the device should be practised for the dierent environmental
conditions with the support of an assistant. For inexperienced users, the
use of anti-tips is recommended.
Danger of tipping over! Drive on slopes and obstacles (steps/
edges) very carefully and at minimum speed. If possible, incline
the upper body forward in the uphill direction (bear in mind the
increased eort required).
For active usersm the seat and back positions must be set to 90°
angle.
When driving over obstacles (steps/gutters), move the anti-tip
into the passive position - to avoid the danger of being broken or
bent (see chapter „Anti-tip“).
To drive over obstacles, actively tilt the unit, if necessary, or take
advantage of the assistance of a support person.
Always approach obstacles head-on. Increased danger of tipping
over with a sloping or sideways approach. Do not drive parallel
on slopes or level crossings - the device might tip over.
Maximum permissible angle of a drivable slope 10°. Do not drive
across the slope because of the increased risk of tipping over.
Increased risk of tipping over when cornering and turning. When
changing the ground clearance, pay attention to footrests.
On long downhill stretches, only drive so fast that the unit can be
brought to a quick standstill at any time.
When folded over or with a back tilt >90° resulting a change of
the centre of gravity, activated anti-tips are necessary!
Stairs/ramps
Only climb stairs with the help of two attendants. Climb stairs
only by pushing or pulling the device, do not carry it. Swivel
antitip into passive position. Be careful for back strain.
Never use escalators (even with an escort). You should only grip
the device by the frame or backrest, never by the push bar or
mounted accessories.

Push rim
Careful of hands when driving through narrow spaces or
entrances - risk of injury.
Do not place your ngers between the wheel cover or back angle
adjustment - risk of crushing.
The push rim can heat up during longer downhill sections or
when braking from fast travel.
Use suitable wheelchair gloves for protection.
4.3 TRANSPORT IN MOTOR VEHICLES
This mobility base is tested according to ISO 7176-19 and approved
as a seat for transport in motor vehicles with wheelchair securement
adapter.
For the transport of passengers in a vehicle, the Mika must be equipped
with the wheelchair securement adapter available from specialist
dealers. This can be ordered mounted on the unit or obtained from a
specialist dealer.
The safest way to transport passengers is in a standard vehicle seat
with a three-point safety belt. Transport in a wheelchair secured in the
vehicle does not oer the same level of safety.
Fixing the mobility base
Mika is only approved for the transport of passengers in
vehicles with a special fastening system (wheelchair securement
adapter).
The wheelchair securement adapter is only approved and to
be used in conjunction with the associated wheelchair support
system. For the transport of wheelchairs / mobility bases
with persons, the motor vehicle must be equipped with the
corresponding wheelchair securement system.
The manufacturer‘s instructions for use for wheelchair
securement adapters / wheelchair support systems must be
followed.
After vehicle collisions, the mobility base, seat shell and
fastening system must be inspected by the specialist dealer
before further use and replaced if necessary.
Passengers may only be transported in mobility base in the
direction of travel.
For transport, all attachments (e.g. tray, loose parts) must be
removed if possible and safely stowed in the vehicle.
The brakes must be applied for transport (see unit setting „Drum
brake“).
Nearby airbags must be deactivated.
Tension or static belts for the front and rear may not be
interchanged.
Recommendation for the mounting brackets on the wheelchair
tie-down and occupant restraint system
4.Handling
As the attachment depends on the wheelchair-accessible
features of the individual vehicle, the manufacturer‘s
information must be observed!
Seat belts
Belts must not be twisted and must be taut so that the user is
adequately secured but comfort is not compromised.
The belt and belt buckle must not be tted over parts of the
mobility bases or the seat shell (e.g. armrests, wheels) and thus
kept away from the body. Buckles must be securely fastened.
The seat belt buckle must be securely latched. The user must be
secured with a lap and shoulder belt.
The lap belt must be close to the body, just above the pelvic bones. The
diagonal shoulder belt runs centrally over the collarbone. To fasten the
diagonal shoulder belt, the buckle on the lap belt must be on the outside
of the pelvis as far as possible. The lap belt buckle is located centrally
between the pelvic bones.
The back should be placed in an upright position (90° angle). A headrest
suitable for transport should be positioned centrally and close to the head
when the head is upright.

When carrying out any adjustment work, be aware of the risk
of pinching and crushing. Adjustments should be made by two
persons to prevent possible injuries!
The numerous possible settings must be adapted to the user regularly
during the course of the disease and during growth. Only an optimally
adjusted mobility base enables a controlled use of the device.
5.1 DRIVE WHEEL
Pay attention to the danger of pinching and crushing!
The parking brake must be readjusted after changing the wheel.
The quick-release axle must be fully engaged.
Observe correct air pressure and sucient tyre tread.
The drive wheel must only be able to be removed when the
button is pressed. Check that the wheel is secure by pulling on
the wheel.
Assembly and adjustments only without occupants.
Mounting the drive wheel
Release the brakes. Press the quick-release axle 1release with one hand
and hold. Pull o the drive wheel 2with the other hand. If necessary, hold
the drive wheel with one hand. Quick-release with the other hand. Operate
the axle release and press the wheel into the drum brake carrier 3until it
engages automatically.
5.2 FRONT CASTOR
The front castor position is decisive for the straight-ahead travel of the
frame and is optimally preset in the delivery state.
Small wheels make the frame more manoeuvrable, large wheels make
it easier to negotiate obstacles.
After changing the size of the drive wheel or altering the range, the
height of the front castor may have to be adjusted.
The steering axle must be perpendicular to the road.
These adjustments may only be carried out by Rehatec® GmbH
and authorised specialist dealers and with an unoccupied
mobility base.

5.3 DIRECTION LOCK OPTIONAL
The direction lock prevents the castors from turning and is suitable for
long straight movements.
Attention must be paid to the danger of pinching and crushing!
When the direction lock is activated, the front castor forks must be in
line.
The castor wheels must be aligned parallel to the drive wheels.
Activate direction lock: Press the knob down.
Deactivate direction lock: Pull the knob upwards.
Aligning the forks
These adjustments may only be carried out by Rehatec® GmbH
and authorised specialist dealers.

again.
5.4 DRIVE WHEEL TRACKING
The wheel track inuences the smoothness of the mobility base and is
optimally preset when delivered.
The distance between the drive wheels and the centre of the unit
should be the same.
5.5 WHEELBASE
Changing the wheelbase has an eect on the driving and tipping
behaviour of the device. The choice of setting depends on the type of use
as well as the individual skills and driving knowledge of the user and the
assistant.
These adjustments may only be carried out by Rehatec® GmbH
and authorised specialist dealers and only when unoccupied.
Attention must be paid to the danger of pinching and crushing.
A short wheelbase requires a condent operation of the mobility
base.
The centre of gravity must be adjusted so that the frame is stable
and cannot tip backwards. If necessary, use anti-tips. Seat and
back angle adjustment change the centre of gravity - risk of
tipping.

Changing the centre of gravity by readjusting of add-on
parts, may have to be corrected via the wheelbase. After
changing the wheelbase, the parking brake must be reset.
A greater distance of the drive wheels from the body‘s centre of
gravity produces greater stability.
The closer the drive wheels are to the body‘s centre of gravity (short
wheelbase), the more manoeuvrable the frame becomes. Driving
characteristics and steering behaviour are improved. The eort
required by the user (self-driver) or assistant is reduced. The risk of
tipping is therefore increased.
Adjusting the wheelbase
Remove the wheel (see chapter „Drive wheel“). Unhook the bowden
cable by pressing the brake release 1up. Undo the screws 2by
holding the nut and remove the drum brake and spacers. If attached,
remove the wheel guard and re-position the wheel. Reassemble the parts
in reverse order.
Tighten the screws alternately until all screws are securely
fastened!
5.6 WHEEL GUARD OPTIONAL
Before making any adjustments, the drive wheel must be removed
(see chapter „Mounting the drive wheel“).

spokeguard 1. Tighten the screws on the spokeguard 1. Replace the
handrim carefully.
5.8 DRUM BRAKE
The brake levers allow assistants to brake while pushing. They cannot be
used by active users.
Check the function of the brakes before every ride. Precise
adjustment of the brakes and regular Maintenance is essential
for safe brake function (see chapter „Maintenance“).
The braking eect must be the same on both sides. Always apply
the brakes on both sides -to avoid danger of tipping over. The
braking eect can be reduced by downhill gradients.
Set the brake to the parking position when the unit is not in use.
Operating the brake levers on the push bar
The braking eect of the locking positions can be set with the
adjustment screw on the brake cable. The braking eect should be
within the ranges shown. The safe parking position must be ensured.
