WARNING Warnings regarding possible risks of severe accident or injury.
CAUTION Warnings regarding possible risks of accident or injury.
NOTICE Warnings regarding possible technical damage.
INFORMATION Information regarding operation. Information for service personnel.
2.2 General Safety Instructions
INFORMATION
Please read the Instructions for Use first! Before using the product, you should become familiar with
the handling, function and use of the product. You may compromise the safety of your child if you do
not observe these instructions.
However, it is impossible to protect against and avoid all unforeseeable circumstances and situa-
tions.
WARNING
Use as a seat for transportation in a vehicle for the disabled
Risk of injury as a result of unauthorized use in a vehicle for the disabled. We recommend that,
whereever and whenever possible, Motus users transfer to the seats installed in the motor vehicle and
use the corresponding vehicle restraint systems, because this is the only way to ensure optimal protec-
tion of the passengers in case of an accident. Only this can ensure optimal protection of the passengers
in case of an accident. Your Motus adaptive wheelchair is permissible for transporting passengers in
motor vehicles when using Otto Bock safety components as well as appropriate restraint systems.
For more information, please refer to our instructions for use manual “Using your wheelchair/ mobility
base with seating shell or buggy as a seat for transportation in motor vehicles“, order no. 646D158.
Danger when overcoming stairs/obstacles
WARNING
Risk of falling in case of lacking assistance. Do not ascend or descend stairs without the assistance
of attendants. Make use of ramps or elevators whenever available. If wheelchair-friendly access is
missing, two attendants must carry the wheelchair over the obstacle.
WARNING
Risk of falling as a result of incorrectly set anti-tipper. If only one attendant is available when as-
cending or descending stairs, an incorrectly set anti-tipper (if mounted at all) can lead to severe falls.
Adjust the anti-tipper so that it does not come in the way of the steps during transport. Afterwards,
swing the anti-tipper back to its operational position.
WARNING
Risk of falling as a result of lifting the wheelchair incorrectly. Attendants must lift the wheelchair only
by parts that are firmly attached (e.g. not at the footrest or rear wheels). If your wheelchair is equipped
with height-adjustable push handles, ensure that the clamping levers are firmly tightened.

42
WARNING
Risk of tipping when using lifting platforms. Ensure that the anti-tipper (if mounted) is outside the
danger-area.
Danger when getting into the wheelchair
CAUTION
Risk of injury as a result of using the footplate for getting into the wheelchair. If possible, the foot-
plates should be flipped up before getting into or out of the wheelchair.
Danger while driving
CAUTION
Risk of accident when driving without experience. This can lead to falls and other dangerous situ-
ations. Therefore, familiarize yourself with the new wheelchair by practicing on even, straightforward
terrain first. Get to know how the wheelchair reacts when the center of gravity shifts; for example on
slopes or inclines or when clearing obstacles such as steps and curbs. This should be done only with
assistance from another person. Using the anti-tipper is strongly recommended for untrained wheel-
chair users.
CAUTION
Risk of tipping when ascending too steep slopes. When ascending slopes or ramps and when cross-
ing obstacles on upward slopes, always lean your upper body far forward.
CAUTION
Risk of tilting or tipping over as a result of centre of gravity shifts. When reaching for objects in
front, to the side or behind the wheelchair, do not lean out of the wheelchair too far.
CAUTION
Risk of tipping when driving against obstacles (steps, curbs) without braking. Use your wheelchair
properly. Do not „jump“ the chair down from higher surfaces.
CAUTION
Risk of accident as a result of incorrect use of the wheel lock. All brakes acting on the tires do not
serve as operating brake but are only designed as parking brake. The wheel locks must not be used
as driving brakes for slowing down the wheelchair, as in extreme cases, the abrupt stopping of the
wheelchair can lead to falls.
CAUTION
Risk of accident if the wheelchair starts rolling. Engage the wheel locks to prevent the wheelchair
from moving on uneven ground or during transfers (e.g. into a car).
CAUTION
Risk of accident as a result of driving in the dark. In the dark, wear light clothing or clothing with
reflectors in order to improve your visibility. Ensure that the reflectors installed on the sides and rear of
the wheelchair are easily visible. We also recommend installing lights.

43
CAUTION
Risk of tipping when descending slopes. Especially on slopes, do not drive without braking and
reduce your speed.
Danger as a result of incorrect assembly or settings
CAUTION
Risk of tipping as a result of incorrectly set wheels. Extreme settings (e.g. rear wheels mounted in
the foremost position) combined with an unfavorable body posture can cause the wheelchair to tip even
on level ground. Avoid extreme settings. For transfemoral amputees, the rear wheels must be shifted
backwards. Use of an anti-tipper is required.
CAUTION
Risk of tipping as a result of missing or incorrectly mounted anti-tipper. Under no condition should
the anti-tipper be used as transport wheels, e.g. when wanting to push the wheelchair while the rear
wheels are removed. The anti-tipper must audibly lock in place, before it is able to bear loads. Firm
seating must be verified by the user or by an attendant.
CAUTION
Risk of tipping as a result of changed diameters/mounting positions of the wheels. If the size
and position of the casters or the rear wheel size are modified, the casters may flutter when driving at
higher speeds. This can lead to blocking of the casters and cause the wheelchair to tip over. For this
reason, you should always maintain the factory settings or, if modifications are required, ensure that
the wheelchair frame is aligned horizontally (see “Adjustment / Assembly Instructions”).
CAUTION
Risk of falling as a result of unintentional loosening of the rear wheels. Always make sure that the
quick-release axles are correctly set on the rear wheel. The rear wheel must not be removable without
the button of the quick-release axle being depressed.
Danger as a result of improper use of the tires
CAUTION
Accident risk due to insufcient or excessive tire pressure! The effectiveness of the wheel lock and
the overall driving quality are dependent on adequate air pressure. The wheel locks are only effec-
tive with sufficient air pressure and proper adjustment (approx. 5 mm distance, subject to technical
changes).
Before starting to use your mobility base with seating shell, check that the tires are inflated correctly.
The required air pressure is printed on the side of the tire. For rear wheels, it should be at least 7.5 bar
(350 kPa). Properly inflated rear wheel tires and equal air pressure in both tires considerably improve
the maneuverability of your wheelchair.
CAUTION
Risk of accident as a result of bad tires. Insufficient tread depth of the tires reduces adhesion. When
using your wheelchair in public traffic, you are subjected to public traffic regulations.

44
Risk of skin damage
CAUTION
Possible complications in case of unhealthy skin. Using the wheelchair with unhealthy skin can cause
medically indicated complications such as reddening of the skin and pressure sores. Over several hours
of use, the skin on the buttocks, back and rear thighs is subjected to considerable strain. Therefore,
always check these areas carefully before using the wheelchair.
No liability will be assumed for health injuries caused by use of this wheelchair with damaged skin.
Danger caused by re/heat and cold
CAUTION
Risk of burns when near to re. The seat and back upholstery may catch fire. Keep the wheelchair
away from all sources of ignition, especially lit cigarettes.
CAUTION
Be careful in case of extreme temperatures. The wheelchair can heat up significantly due to solar
radiation or in the sauna. In extreme cold, there is a risk of hypothermia.
Risk of hand injuries
CAUTION
Risk of hand injuries. To avoid hand injuries, do not grasp between the rear wheel and the wheel lock
when driving your wheelchair.
CAUTION
Risk of pinching between wheelchair components. The wheel lock lever and the side or frame sec-
tions can represent a risk of crushing with various adjustment options.
CAUTION
Risk of friction burns. Slowing down from high speeds or when descending longer slopes tends to
heat up the hands and fingers, especially if using aluminum push rings. When using your wheelchair
outdoors, wear leather gloves. Gloves provide you with a better grip and protect your fingers from dirt
and hot metal.
Warnings regarding wheelchair damage
NOTICE
Damage caused by overload. The maximum load capacity of the Motus adaptive wheelchair is
125 kg or 140 kg in connection with double crossbrace.
NOTICE
Damage caused by wear and tear. If the upholstery gets worn or damaged, replace it immediately.
NOTICE
Damage caused by incorrect packaging. Only use original packaging for shipment of the product.

45
3 Delivery / Preparing the Wheelchair for Use
CAUTION
Risk of pinching. Only grip the components shown when folding or collapsing the wheelchair.
Your wheelchair is usually delivered fully assembled with the backrest folded and with the rear
wheels removed.
A few simple steps are sufficient to prepare it for use:
Attach rear wheels. To attach the rear wheel, press the button on the quick-release axle, slide
four fingers between the spokes and press the button of the quick-release axle with your thumb
(fig. 1). Then attach the rear wheels to the fittings and the axles will automatically engage.
While standing next to the wheelchair, tip it slightly toward you. Press apart the crossbrace
with flat of the hand (fig. 2). Make sure that the crossbrace has locked in the support brack-
ets (fig. 3).
Pull the bib of the back upholstery upwards and attach the bib to the wheelchair‘s seat up-
holstery (fig. 4).
Insert the seat cushion (fig. 5).
Finally, fold down the footplates (fig. 6).

CAUTION Accident risk. When remounting, be sure the quick-release axle securely locks into the
quick-release axle housing! The rear wheel must not be removable when the button is not being
pressed!
CAUTION
Risk of tipping. The rear wheels have been pre-positioned according to your indications.
Before using the wheelchair, this pre-adjusted position must be checked by the wheelchair user
for function and stability against tipping with the assistance of skilled staff.
4 Transportation
Pull the footrest up and remove the seat cushion.
Grab the seat upholstery at the front and the back in the middle and pull it upwards: The wheel-
chair will fold (fig. 7).
For more manageable transportation, e.g. in cars, the footrests can be swung outwards or be
entirely removed in just a few easy steps.
7 8
To move or remove the footrest, pull the swivel handle to the rear (fig. 8). The footrest with foot-
plate can then be swung away to the inside or outside by 90° (g. 9), or be swung away and
removed by pulling upward (fig. 10).

47
9 10
INFORMATION During reassembly, ensure that the footrest locking device has engaged.
The standard equipment includes removable quick-release axles on the rear wheels which fa-
cilitate transportation of your wheelchair.
To remove the rear wheels, press the button on the quick-release axle as described in Chapter
3. The rear wheels can then be removed. (fig. 1).
CAUTION
Accident risk. During assembly, confirm that all bolts engage in the corresponding bore
holes and that the quick-release rear wheel axles and casters securely lock into their axle hous-
ings. The rear wheels and casters must not be removable without the button being depressed!
Check the function of the brakes.
4.1 Transfer
Transfer into the wheelchair is described below. The Motus is designed for persons who normally
move around in the wheelchair independently. Therefore, the independent transfer is described.
Should you require an attendant, the steps described here are carried out correspondingly but
with support.
Maneuver the wheelchairs so that they are positioned at an angle of approx. 45° degrees to
each other (fig. 11). Ensure that the wheel locks do not get caught in each other but remain freely
movable. First activate the wheel locks of the wheelchair that is currently in use (fig.12).
11 12

48
Then activate the wheel locks of the wheelchair you want to transfer into (fig. 13). Flip up the
footplates of the Motus (fig. 14). Move your feet from the footrest to the floor and move ahead in
the wheelchair if required (fig. 15).
13 14
Transfer into the second wheelchair. The method illustrated is one possible way to support your-
self (fig. 16). Find the most suitable path for you by practicing with an attendant.
15 16
Push the footplates of the Motus down again (fig. 14). Position your feet on the footplates of the
wheelchair (fig. 17). Release the wheel locks (fig. 18). Now you can use the wheelchair.
17 18

49
5 Options
The wheelchair is designed as a modular assembly system. This means that certain accessories
can be adapted to your wheelchair.
We recommend using a seat cushion at all times. The seat upholstery of the Motus has a loop
texture so that seat cushions can be attached with hook and loop connection. All seat cushions
listed on the order form have the required hook texture.
Furthermore, we will present you a selection of our variants and accessories which improve the
use and comfort of your wheelchair.
5.1 Anti-tipper (Fig. 19/20)
Prevents the wheelchair from tipping too far backward. The anti-tipper can be adjusted in length
without need of tools depending on seat height and seat angle (fig. 20). Strongly recommended
for untrained wheelchair users as well as when extreme adjustments have been made to the
rear wheel (for assembly instructions see Chapter 5.11).
19 20
5.2 Transport Wheels (Fig. 21)
With the rear wheels removed, the wheelchair can still be used as a rolling base; this makes it
possible to manoeuvre through narrow passages (e.g. narrow bathroom doorways or airplane
aisles).
CAUTION Accident risk. Please note that once the rear wheels are removed, the wheel locks can
no longer be activated!

50
5.3 Crutch Holder (Fig. 22)
Allows crutches to be attached to the wheelchair.
21 22
5.4 Tip-assist (Fig. 23)
Makes it easier for an attendant to tip up the wheelchair, e.g. to cross a step. The tip-assist must
be mounted so that the distance to the ground is at least 4 cm.
5.5 Plug-on Side Panels (Fig. 24)
These side panels can be removed for getting into or out of the wheelchair. To remove the side
panels, pull the out of the side panel attachment. Additionally, the armrest can be adjusted in
height.
23 24
5.6 Desk Side Panels (Fig. 25)
The side panels can be swung away to the rear for transfer. For this purpose, press the half-
moon push buttons and swing the side panel away to the rear. Remove the side panel in vertical
position by pulling it upward. Moreover, the armrest is adjustable in height.

51
5.7 Plug-on Wheel Lock Lever Extension (Fig. 26)
The extension facilitates the wheel lock lever control to the users with limited hand function.
25 26
5.8 Rear Wheel with Drum Brake (Fig. 27)
The drum brakes allow the attendant to comfortably and safely brake the wheelchair. The rear
wheels remain removable via the quick-release axle system.
5.9 Tray (Fig. 28)
Serves as a supporting surface during meals, when working or when playing. The clear material
allows visibility of the legs and correction of the sitting posture.
27 28

52
5.10 Elevating Footrest (Fig. 29)
Allows positioning of the leg at different angles. Upon manipulation of the release lever which is
integrated into the swivel segment the footrest angle can be adjusted in small increments.
5.11 Push Handles, Height-adjustable (Fig. 30)
Can be adjusted vertically to a more comfortable height for the attendant.
29 30
5.12 Wheelbase Extension (Fig. 31)
This option makes the wheelchair particularly stable against tipping and at the same time in-
creases the turning radius.
INFORMATION For transfemoral amputees the long wheelbase setting is indispensable.
5.13 Angle Adjustable Back (Fig. 32)
The seat design allows the backrest angle adjustment by 30°. The unlocking of the adjustable
back is activated via the pull cable.
31 32
5.14 Spoke Protector (not illustrated)

6 Adjustment / Assembly Instructions
INFORMATION
The following tools are required for repair and maintenance:
• Allen wrenches, sizes 4 and 5 mm
• Open-end wrenches, sizes: 10 mm, 11 mm, 13 mm, and 24 mm
• Set of screwdrivers
• Torque wrench
• Tire levers
• Tire pump
All wheelchair users have expectations regarding wheelchair type, accessories, seating and
handling. Your Motus adaptive wheelchair offers many options that permit the wheelchair to be
adapted according to your requirements. We recommend consulting with your dealer or therapist
to determine which wheelchair settings will work best for you.
6.1 Adjusting Seat Height and Seat Inclination (Fig. 33)
The higher the rear wheel is attached to the frame, the more the seat inclines downward. This
has two effects:
First, the wheelchair has a greater tendency to tilt backwards.
Secondly, the user sits deeper in the wheelchair and thus has more stability.
A careful and synchronized height adjustment of both the rear wheels and the casters will allow
to adapt the seat height to the user’s individual requirements.
The Motus offers the possibility to change vertical position of the rear wheel by shifting the rear
wheel adapter along the frame. Loosen all four screw connections (Fig. 33, see arrow) and
remove the screws. Shift the adapter to the desired position and firmly retighten the screws.
To achieve additional rear wheel positions, the rear wheel adapter can be turned by 180°.
INFORMATION
When the rear wheel position is changed, the angle of the caster axle in relation to
the ground also changes. Ensure that this angle is always approx. 90° wide (see Chapter 6.3).
The wheel lock must be re-adjusted as well (see Chapter 6.4).
INFORMATION
Make sure to firmly retighten all screws and nuts after making adjustments. The proper
torque for the screw connection of the rear wheel adapter is 8 Nm. The proper torque for the
screw connection of the fitting is 50 Nm.
33

•

54
6.2 Changing the Wheelbase (Fig. 34)
Shifting the rear wheel backwards lengthens the wheelbase and thus provides for greater sta-
bility of the wheelchair. Shifting the rear wheel forwards (only for advanced wheelchair drivers!)
relieves the load on the casters. This increases the maneuverability of the wheelchair. The caster
wheels can then also be lifted more easily to clear obstacles such as curbs or steps.
Loosen the screw connections from the fitting (fig. 34, see arrow) and remove the fitting. Shift
the fitting to the desired position and firmly retighten the screws.
The distance between rear wheel and side panel can be continuously adjusted by adjusting the
counter nut on the outer side of the rear wheel adapter.
When changing the adjustments originally made in the factory, two other component groups of
the wheelchair must be readjusted, refer to Chapters 6.3 and 6.4.
CAUTION Risk of tipping. Please note: If the rear wheels are in a more forward position and the
user‘s body is not appropriately positioned, the user may tip backward - even on level ground!
CAUTION
Risk of tipping. For untrained wheelchair users and when there are extreme adjust-
ments to the rear wheel, an anti-tipper is strongly recommended!
CAUTION
Risk of tipping. For transfemoral amputees it is essential to shift the rear wheels back-
wards!
INFORMATION
Make sure to firmly retighten all screws and nuts after making adjustments. The proper
torque for the screw connection of the rear wheel adapter is 8 Nm. The proper torque for the
screw connection of the fitting is 50 Nm.
34
6.3 Caster Trailing Adjustment (Fig. 35-38)
After the rear wheels have been mounted in the appropriate position, the caster wheel journal
angle must be readjusted. The threaded axle should be as horizontal as possible in relation to
the ground to ensure optimal driving behavior of the wheelchair. The caster adapter allows for
continuous angle adjustment.
Remove the cap from caster head bearing with a screwdriver (fig. 35). Then remove the protec-
tive cap from the screw connection on the frame inner side (fig. 36).
Loosen the rear screw connection as shown in fig. 37.

55
Open the screw connection of the eccentric. Place the bubble level on the caster wheel journal
and adjust the eccenter with a screwdriver (fig. 38). Retighten all screw connection and put on
the cover caps.
INFORMATION The proper torque for tightening the screws is 8 Nm.
35 36
37 38
6.4 Adjusting the Wheel Lock (Fig. 39)
To change the position of the rear wheels, first loosen the attachment screws of the clamping
adapters of the wheel lock and push the wheel lock forward. Then reposition the rear wheels. The
wheel lock should then be remounted such that the distance between the tires and wheel lock bolts
is max. 5 mm when the wheel lock is not activated (fig. 39; subject to technical changes).
CAUTION
Accident risk. The wheel locks are only effective with sufficient air pressure and proper
adjustment. The proper air pressure is indicated on the side wall of the tire. It should be at least
7 bar (350 kPa). To ensure sufficient braking effect, use only original rear wheels with an ap-
proved radial excursion of maximally ± 1 mm.
INFORMATION Make sure to firmly retighten all screws and nuts after making adjustments.
INFORMATION Tighten the wheel lock attachment with a torque of 10 Nm.
