2. Handling the wheelchair
2.1 Application
The IMPULS 1 wheelchair is a standard
lightweightwheelchair witha fixeddriv-
ing wheel position.
IMPULS 2-4 models are activity wheel-
chairs, which can be adapted to suit the
corresponding requirements of respec-
tive users.
The Impuls XX wide wheelchair is for
heavier users weighing up to max. 160
kg.
The Impuls Postura wheelchair offers a
padded backrest with angle adjustment
and a padded seat, which can also be
adjusted in depth.
IMPULS System wheelchairs are de-
signed for daily use, both indoors and
outdoors, for work or for leisure. For the
experienced user, the IMPULS System
wheelchair offers possible settings for
active performance with high manoeu-
vrability.
Before being used for the first time, the
wheelchair should be adjusted by your
ORTOPEDIA dealer. The adaptation will
take into account the driving experi-
ence, the physical limits of the user and
the main place of use of the wheelchair.
!Warning:
Settingor adjustmentshould onlybe
carried out by an authorised ORTO-
PEDIA dealer.
1. Introduction
Thankyouchoosingawheelchairfromthe
IMPULS model range.
With its many design versions and acces-
sories,theIMPULSwheelchair system can
be adapted to suit your varying clinical
needs.
Like any other vehicle, a wheelchair is a
technical aid. It requires explanations for
use and a degree of maintenance. It also
has hidden dangers that may appear if it
is used incorrectly. It is therefore impor-
tant to learn how to handle it correctly.
These instructions are intended for use in
conjunction with the booklet "Safety In-
formation for Mechanical Wheelchairs",
tohelpyouto familiarise yourselfwiththe
operation of the wheelchair and to pre-
ventaccidents.
Children should read these instructions
and the booklet "Safety Information for
Mechanical Wheelchairs" with their par-
ents, guardian or carer before venturing
out for the first time.
☞Note:
Please note that the equipment ver-
sions illustrated may differ from your
model.

2.4 Additional user/
safety information
▲When travelling in public thorough-
fares, clean passive lighting must be
used!
▲Do not throw or drop parts belong-
ing to the wheelchair!– Removable
parts such as armrests and leg sup-
ports should be handled correctly to
ensure lasting performance. To guar-
antee their function.
▲Beforemoving off,check thatremov-
able parts such as armrests and leg
supports, are locked correctly in po-
sition. Drive wheels with defective
linchpin (quick-fit) axles can detach
fromthe wheelchairduringthe drive.
▲The addition or removal of accesso-
ries/components will cause the di-
mensions and weight of the wheel-
chair to change. This can also result
in a change in performance.
▲Never leave children/young persons
unsupervised in wheelchairs.
▲For smaller obstacles, e.g. small
ledges/slopes, always move slowly
and at a right angle (90°) to the ob-
stacle, until the swivel wheels are al-
most touching the obstacle. Briefly
stop the wheelchair and then drive
over the obstacle.
▲Give a wide berth to grooves, rails,
manhole covers or similar sources of
danger. If not possible, cross such
obstacles at a right-angle (90°).
▲Maintain a safe distance from steep
inclines, staircases and obstacles to
allow sufficient space to react, brake
and turn.
▲Always reduce speed before a bend.
A sharper curve requires a lower
speed. Never lean outwards in a
curve.
2.2 Performance
Optimisation of the performance char-
acteristics of the IMPULS System wheel-
chair to fit your personal circumstances
should be discussed with your
ORTOPEDIA dealer or physician.
The adaptability of the wheelchair of-
fers you a high degree of comfort and
safetyin all areas of life, e.g. family, work
or leisure.
2.3 Safety information
▲Please follow the safety information
for mechanical wheelchairs con-
tained in the relevant booklet.
▲A direct change of movement to the
opposite direction, e.g. from reverse
toforwardmovement withoutinvolv-
inga steeringaction, causesfull brak-
ing if the swivel wheels are moving
inwards at the same time.
▲The use of a safety belt prevents the
user from falling out of the wheel-
chair.

2.4.1 User information
The following pages give general infor-
mation and suggestions for handling
and use of the wheelchair in everyday
situations.Make yourselfthoroughlyand
carefully familiar with the wheelchair.
Newdriving situationsmustbe practised
with the support of a helper.
▲Before changing from one seating
option to another, or before leaving
or entering the wheelchair, always
lock the brakes to prevent the wheel-
chair from rolling away.
▲To lean the upper body well forward,
manoeuvre the wheelchair back-
wards until the swivel wheels face
forwards for increased stability.
▲Tyres are made of a rubber com-
poundand mayleave marksonsome
surfaces (e.g. plastic, wooden or par-
quet flooring, rugs, carpets) that are
hard to remove or even permanent.
▲To prevent damage from corrosion,
do not use the wheelchair in damp
conditions, do not travel through
puddles or water and do not expose
it to continuous rain.
Recommendations for travelling
at dusk or at night
▲During periods of darkness, avoid
roads and cycle paths as far as possi-
ble.Wearlight-coloured clothing that
can be seen at a distance.

2.5 Folding/unfolding
2.5.1 Folding the wheelchair
To fold the wheelchair (Fig. 1), fold up
the foot plates of the leg supports or
remove the leg supports. Press the cen-
tre of the chest belt backwards. Lift the
back and the front of the seat cover up-
wards from the centre (Fig. 2/ ➀).
2.5.2 Unfolding the wheelchair
To unfold the wheelchair, tilt it slightly
to one side. On the side which is stand-
ing firm on the ground, push the seat
tube downwards until it reaches its limit
(Fig. 2/ ➁).
☞Note:
To do this, it may be necessary to
force both seat tubes into their final
position by hand.
The Bowden wire (Fig. 2.1/ ➀) pre-
vents the side frames being pushed
too far apart.

Loading the wheelchair
Loading the wheelchair
Wheelchair and the car
Move the wheelchair parallel and adja-
cent to the driver or passenger seat.
Detach the legrests and the armrests in
order to reduce the wheelchair weight
and make the lifting into the car easier.
Lock the brakes to prevent the wheel-
chair from moving. The door frame can
be used for holding or the seat for sup-
port during the transfer into the car.
A sliding board can be used to bridge
the gap between the wheelchair and
the car seat. The possibilities here de-
pend on the type of vehicle, the height
of the car seat and the height of the
wheelchair seat.
Unlock the brakes of the wheelchair
before its loading. The personal possi-
bilities and the spaciousness of the vehi-
cle determine whether the wheelchair
is now pulled into the car from the driv-
er's seat or the front passenger seat.
Two-door cars usually cause fewer prob-
lems because the doors are usually
wider. In the case of a four-door car it
may be necessary for a helper to lift the
wheelchair into the passenger space or
the boot.

2.6 Transportation
For storage or transportation purposes,
the wheelchair can be dismantled into
portable elements without the need for
tools.
Firstly the dimensions of the wheelchair
can be reduced by removing all remov-
able parts. These include the leg sup-
ports and the armrests (arm pads are
not removable). Stabilisers (if present)
can be folded forwards.
The wheelchair can now be folded in
the normal way. In addition, driving
wheels equipped with full floating axles
can now also be removed.
During reassembly, ensure that each
part is correctly installed and securely
fastened. Check that components are
correctly positioned. Check the correct
seating of the components.
3. Overview
Theoverview shows the most important
components and operating elements of
the IMPULS System wheelchair.
The components shown in the follow-
ing illustrations may not be identical to
those on your wheelchair. The location
and handling of the parts are neverthe-
less applicable to your IMPULS System
wheelchair model. Each time the wheel-
chair is assembled, or each time a set-
ting is made, checks should be carried
out to ensure that the component in
question is fitted correctly and function-
ing properly.

adjustment and length
compensation (774-2 AL)
When seated in the wheelchair, ask a
carer to raise the leg support to the de-
sired level. The length of the leg sup-
port is automatically adjusted by spring
force.
To lower the leg support, remove the
load momentarily from the support by

3.3.5.2 Hand wheels
The distance between the hand wheels
and the driving wheels is adjustable. To
changethis distance,loosen thefour fix-
ingscrews (Fig. 32/ ➀) byapproximately
one turn. Move the hand wheel to the
required position parallel to the driving
wheel. Tighten the fixing screws cross-
wise.
3.3.6 Brakes
The wheelchair can be halted via the
hand wheels, the toggle joint brakes
(Fig. 33) or the drum brakes (carers
only).
3.3.6.1 Safety information
▲The wheelchair must not be pushed
when the brakes are locked on.
▲If the braking effect reduces, the
wheelchair should be repaired immedi-
ately at an authorised repair centre.
▲In order to prevent unwanted swerv-
ing when stopping the wheelchair or
when locking the brakes on a sloping
surface, both brake levers should be ac-
tivatedsimultaneously.

3.3.5 Driving wheels
The driving wheels are mounted on a
fixed axle or a full floating axle, depend-
ing on the wheelchair model.
☞Note:
The tyre pressure is shown on both
sides of the tyre surface and can also
be found in the Technical data.
3.3.5.1 Full floating axle
The driving wheels can be installed or
removedwithout theneed fortools (Fig.
30). Free the axle by pressing on the
rubber cap and pull outwards.
To install the driving wheels, free the
axle by pressing on the rubber cap (Fig.
30) and push the wheel into the axle
opening until it locks.
!Warning:
Each time the wheels are installed,
test the locking mechanism by pull-
ing/pushing the driving wheel from
the side (Fig. 31). – The full floating axle must be kept
clean. A functional fault may occur
in the case of contamination due to
sand or earth or in the event of freez-
ing of moist cold air.
– If the drive wheel has too much lat-
eral play or the full floating axle does
not lock, it should be repaired im-
mediatelyby anauthorised ORTOPE-
DIA dealer.

3.3.6.5 Locking the brake
To secure the wheelchair against unin-
tentional movement, both lateral brake
levers should be pushed forward until
they reach their limit stops (Fig. 36).
3.3.6.6 Releasing the brake
To release the brake, both brake levers
should be pulled backwards until they
reach their limit stops (Fig. 37).
3.3.6.7 Changing or replacing
driving wheels
After a change of driving wheels, checks
should be made to ensure that the
brakes are functioning correctly. The
brakes should then be reset if necessary
Driving wheels with PU tyres require a
special toggle joint brake.
Whenchangingto awheelwithPU tyres,
or from PU tyres to another type of tyre,
thetoggle jointbrakes mustbe changed
at the same time.

▲Do not lean on the lateral brake lever
(Fig. 34/ ➀).
!Warning:
The braking effect is dependent on:
– the condition of the tyres,
– the condition and fixing of the
brakes,
– the brake lever setting,
– the quality of the road surface.
3.3.6.2 Toggle joint brake
Activationofthetoggle joint brakecauses
a brake bolt to press on the tyre (Fig.
