2. Handling the wheelchair
2.1 Use
The Impuls-ORTOform wheelchair is a
therapywheelchair forthe domestic and
geriatric care.
The
Impuls-ORTOform offers an uphol-
stered seat, an angle-adjustable, uphol-
stered backrest and a seat depth adjust-
ment with variable drive wheel position
for a comfortable, relaxed sitting.
The
Impuls-ORTOform isdesignedfor the
daily use indoors and outdoors.
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.
!
Attention:
Settingor adjustmentshould onlybe
carried out by an authorised ORTO-
PEDIA dealer.
1. Introduction
Thank you for choosing a wheelchair
from the IMPULS model range.
With its many design versions and acces-
sories,
Impuls-ORTOform wheelchair sys-
tem 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. The correct handling
must therefore be learned.
These instructions are intended for use in
conjunction with the booklet "Safety In-
formation for Mechanical Wheelchairs",
tohelpyou to familiariseyourself withthe
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
▲A clean, passive illumination is re-
quiredfor thedriving onpublic high-
ways/pavements!
▲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.
▲Removable parts, e.g. armrests and
legrests, must be checked for correct
lockingbefore thestart ofeach drive.
Drive wheels with defective linchpin
(quick-fit) axles can detach from the
wheelchair during the drive.
▲The fitting/removal of accessory
parts/components alters the dimen-
sions and weight of the wheelchair
and consequently the driving behav-
iour.
▲Never leave children/adolescents in
wheelchairs unsupervised.
▲Always drive up to small obstacles,
e.g.drops/steps, slowlyand at aright
angle (90°) until the swivel wheels
almosttouch the obstacle.Briefly stop
the wheelchair and then drive over
the obstacle.
▲Keep well clear of rail grooves, rails
and gully covers or similar sources of
danger. If not possible, cross such
obstacles at a right-angle (90°).
▲Maintain a sufficient safety distance
betweenthe vehicleand drops,steps
and obstacles. This distance must al-
lowenoughtime toreact andenough
distance to brake/turn.
▲Always reduce the speed before a
curve. A sharper curve requires a
lower speed. Never lean outwards in
a curve.
2.2 Performance
Optimisation of the performance char-
acteristics of the wheelchair to fit your
personal circumstances should be dis-
cussed with your ORTOPEDIA dealer or
physician.
The adaptability offers you an adequate
driving comfort and a high operational
safety.
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
toforward movement withoutinvolv-
inga steeringaction, causes fullbrak-
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 yourselfthoroughly and
carefully familiar with the wheelchair.
Newdriving situationsmustbe practised
with the support of a helper.
▲Always lock the brakes in order to
prevent the wheelchair from moving
before the transfer from/into the
wheelchair.
▲Before moving the upper part of the
body far forwards whilst in the
wheelchair, increase the stability of
the wheelchair by moving it rear-
wards until the steering wheels point
forwards.
s Tyres are made of a rubber mixture
and can leave permanent or difficult-
to-remove marks on some surfaces
(e.g. plastic, wooden or parquet
flooring, carpets, mats).
▲In order to prevent corrosion dam-
age, do not use the wheelchair in
damp rooms, do not drive it through
puddles or water and avoid a long-
term exposure to rain.
Recommendation for driving in
twilight or darkness.
▲Avoid as far as possible driving on
roads or bicycle paths during dark-
ness. Wear light-coloured clothing
that can be seen at a distance.

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, armrests (armrest pads are not
detachable), seat and backrest. Stabi-
lisers(if present)can befolded 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 showsthe mostimportant
components and operating elements of
