1.1 Preface
Congratulations on choosing a lightweight wheelchair from the Start series, a high-quality product that offers versatile applications for everyday use at home and outdoors. Before using your
wheelchair, it is essential to read the sections “Delivery / Preparing the Wheelchair for Use” and
“Safety Instructions” .
The section “Accessories” presents additional components of the Start which can expand its
field of application and improve its comfort. The section “Adjustment / Assembly Instructions”
provides an overview of the possibilities to customize the wheelchair to your personal needs
and preferences. The model as described in these Instructions for Use is subject to technical
changes without notice.
1.2 Intended Use
The lightweight wheelchairs of the Start series are designed solely for people who are unable to

2.2 General Safety Instructions
DANGER!
To avoid t ippi ng and d ange rous s itu atio ns, famil iar ize your self w ith your new whe elc hair
by practicing on level ground first.
DANGER!
Do not use the footplates as a step stool when getting into or out of your wheelchair.
These should be flipped and swung out of the way first, if possible.
DANGER!
Depending on the diameter and setting of the casters as well as the setting of the
wheelchair’s center of gravity, the casters may flutter when driving at higher speeds.
This can lead to blocking of the casters and cause the wheelchair to tip over. Therefore,
ensure that the casters are properly adjusted (see section “Adjustment / Assembly
Instructions”).
Especially on slopes, do not drive without braking and reduce your speed.
DANGER!
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 wheelchair users.
DANGER!
The anti-tipper is designed to prevent the wheelchair from tipping backwards. 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.
DANGER!
Extreme settings (e.g. rear wheels mounted in the foremost position, M4 / M5)
combined with disadvantageous body postures can tip the wheelchair even when
on level ground.
DANGER!
When ascending slopes, lean your upper body far forward.
DANGER!
When reaching for objects in front, to the side or behind the wheelchair, do not lean
out of the wheelchair too far as this will shift the center of gravity and cause the
chair to tilt or tip over.
DANGER!
Use your wheelchair properly. For instance, do not “jump” the chair down from
higher surfaces and do not drive against obstacles such as steps and curbs without
braking.
Page 7
42
DANGER!
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.
If only one attendant is available, he or she must adjust the anti-tipper (if mounted)
such that it does not come in the way of the steps during transport. Failure to observe
this precaution can lead to severe falls. Afterwards, the anti-tipper should be swung
back to its operational position.
DANGER!
Advise attendants to lift your wheelchair only by parts that are firmly attached (e.g.
not at the footrest or the flip-up side panels).
DANGER!
If your wheelchair is equipped with height-adjustable push handles, ensure that the
clamping levers are firmly tightened.
DANGER!
When using lifting platforms, ensure that the anti-tipper is outside the dangerarea.
DANGER!
Engage the wheel locks to prevent the wheelchair from moving on uneven ground or
during transfers (e.g. into a car).
DANGER!
Before starting your wheelchair, check the tires for proper inflation levels. The required
air pressure is printed on the side of the tire. For rear wheels, it should be at least
3.5 bar (350 kPa). The wheel locks are only effective with sufficient air pressure and
proper adjustment (approx. 4 mm distance, subject to technical changes).
DANGER!
For transfemoral amputees, the rear wheels must be shifted backwards.
ATTENTION!
If your seat and back upholstery become worn out or damaged, replace it promptly.
With a new seat upholstery you will automatically receive new lamellar plugs for the
seat tube which you should replace for the previously used, old lamellar plugs.
DANGER!
Use caution near flammables or fire, especially lit cigarettes. The seat and backrest
upholstery might catch fire.
DANGER!
To avoid hand inju ries, do not g rasp betw een t he re ar wh eel a nd t he wh eel l ock
when driving your wheelchair.
DANGER!
The maximum load for modules M1, M2, M3 and M5 is 125 kg.
The maximum load for module M4 is 160 kg and for module M6 90 kg.

DANGER!
Using your Otto Bock product as a seat for transportation in motor vehicles for
disabled passengers
Whenever possible, users should be transferred to the seats installed in the
motor vehicle for disabled passengers. The corresponding restraint systems
should also be used. Only this can ensure optimal protection of the passengers
in case of an accident.
The modules M1, M2, M3, M5 and M6 are permissible for transporting passengers
in motor vehicles when using Otto Bock safety components and when using
appropriate restraint systems.
For more information, please refer to our instructions for use manual “Using your
Wheelchair/ Mobility Base with Seating Shell or Buggy/Stroller as a Seat for
Transp ortation in Motor Ve hic les”, ord er no. 646 D158.
DANGER!
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!
Slowing down from high speeds or when descending longer slopes tends to heat
up the hands and fingers, especially if using aluminum push rings.
INFORMATION!
When using your wheelchair outdoors, wear leather gloves. Gloves provide you with
a better grip and protect your fingers from dirt and hot metal.
INFORMATION!
The effectiveness of the wheel lock and the overall driving quality are dependent on
adequate air pressure.
Properly inflated rear wheel tires and equal air pressure in both tires considerably
improve the maneuverability of your wheelchair.
INFORMATION!
Ensure that the tires have sufficient tread depth.
When using your wheelchair in public traffic, you are subjected to public traffic
regulations.
INFORMATION!
Ensure you are visible in the dark. If possible, wear light-colored clothes or clothing
with reflectors, and ensure that the reflectors installed at the side and the rear of the
wheelchair are clearly visible. We also recommend installing lights.

6 Adjustment / Assembly Instructions
All wheelchair users have expectations regardingwheelchairtype,accessories,seatingand
handling.
Your Start wheelchair has many options by which it can be customized to your needs and preferences. We recommend consulting with your dealer or therapist to determine which wheelchair
settings will work best for you.
INFORMATION!
The following tools are required for repair and maintenance:
• Allen wrenches, sizes 4 and 5 mm
• Torx Allen wrenches, sizes x 30
• Open-end wrenches, sizes 19 and 24 mm
• Socket wrenches, sizes 10 and 19 mm
• Phillips head screwdriver
• Tire levers
• Torque wrench
6.1. Adjusting seat height and seat inclination
The higher the rear wheel is attached to the frame, the more the seat inclines downward. This
positions the user deeper and more firmly into the seat. However, rear wheels that are attached
high at the frame also make the wheelchair more prone to tilt backwards. 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.
INFORMATION:
Please note: 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 “Caster wheels”). The wheel lock must be re-adjusted as well (see
“Wheel lock”) .
Page 17
52
INFORMATION:
The Start M1 Intro, M2 Effect, M3 Hemi and M6 Junior offer the possibility to
change the vertical position of the rear wheel by shifting the rear wheel adapter
along the frame. Loosen the two screw connections A (Fig. 24) and remove the
screws. Shift the adapter to the desired position and firmly retighten the screws.
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.
For Start M4 XXL and M5 Comfort: Loosen the nut A (Fig. 25) of the quickrelease axle housing on the inside of the frame and remount the axle housing at
the desired position. The proper torque is 50 Nm. The distance between rear
wheel and side panel can be continuously adjusted by adjusting the counter nut on
the outer side of the frame.

Changing flat tires requires only the necessary tools and minimal technical skills. Users may
change tires themselves if they wish. We recommend carrying an emergency repair set and
an air pump at all times (if using pneumatic tires). Alternatively, users can keep a spray can of
hardening foam (available at bicycle shops) to fill a tire in case of punctures.
• In case of a flat tire, carefully remove the tire from the rim using the appropriate tools.
• Take care not to damage the rim or the inner tube.
•Repairtheinnertubeaccordingtothedirections in the repair kit, or, replace the damaged
inner tube with a new one.
•Beforere-mountingthetire,inspecttheinnerrimsurfaceandtheinsideofthetireforanyobject
that may have caused the puncture.
• Be sure that the rim bands are not damaged. They protect the tube from being damaged by
the ends of the spokes.

• Check around the tire on both sides to ensure that the tube is not clamped between the edge
of the tire and the rim.

• Inflate the tire until it can still be pressed easily with your thumb. If the control line on both sides
of the tire is equally distanced to the rim, the tire sits centrally. If the tire does not sit centrally,
let out some air and realign the tire. Then inflate the tire to the pressure indicated on the side
wall and tighten the dust cap.
