1.1 Important safety instructions before using e-drive
For safety reasons e-drive must only be operated by people who:
•Have received instruction on using e-drive
•Are in good physical and psychological health, so as to be able to control e-drive
safely in all operating situations.
Instruction on operating e-drive is included in the scope of the delivery and will be provided
at a time agreed through your specialist dealer or a Decon Wheel representative. This service
is completely free of charge.
If youstill do not feel safe using e-drive, please contact your specialist dealer
e-drive has been programmed to suit you by your local dealer. The performance shall not be
changed because it will effect the road performance and be dangerous for you
Adhere to all the values the wheelchair manufacturer has specified in the directions for use,
particularly maximum clearance limits. Also carefully follow the operating and safety
instructions in the directions for use of the wheelchair.
Always switch e-drive off and activate the parking brake before moving to or from the
wheelchair.
e-drive is dimensioned for indoor and outdoor use, but a basic prerequisite is that you travel
on a stable surface.
Despite e-drive being dimensioned in accordance with all current EMC directives,
electromagnetic fields may affect driving characteristics. Mobile phones and other
devices that emit electromagnetic radiation can in certain cases cause incorrect
function. Likewise, e-drive may cause disturbances in electromagnetic fields. This is
rare, though it can lead to triggering of alarms in older alarm installations, e.g. in
department stores, or to opening of older automatic doors.
Make sure you are in a safe place and switch e-drive off, before using a mobile phone or a
similar device. Avoid driving in the proximity of strong electric fields as traffic lights,
electrical wires and transformers that can cause interference. E-drive can by itself create
electrical and radio waves. E-drive can disturb electrical equipment. It can cause interference
on equipment in a hospital or other places that have electrical instruments.
On no account start e-drive up before receiving instruction from your specialist dealer or a
Decon Wheel representative.

Installing the e-drive
Your local dealer shall have mounted all necessary components on your wheelchair. If you receive the
chair without the wheels mounted on the chair, follow the instructions as you see below. If the
wheels does not fit on the chair, contact your local dealer.
1. Start fitting e-drive to your wheelchair. The wheels have a quick release axle (QR axle).
Press the button and assembly the wheel on the chair. Picture 1
2. When installing the wheels you need to lift the wheelchair up a little with your hand. Then
insert the QR axle . It is very important that the axle be pressed in far enough; otherwise the
QR axle may come off. Picture 2 and 3

the battery in the battery holder as shown in picture 2.

Overturn protection
Before you start using e-drive for the first time you must check that the overturn protection is
fitted to your wheelchair.
For safety reasons you should only remove the overturn protection in order to get
over an obstacle, e.g. a high kerb. The assistance of another person will then be
necessary.
The installation instructions supplied with your wheelchair must be observed when
fitting and removing the overturn protection.
GUIDE FOR SAFE DRIVING
When you get your chair with e-drive fitted to it, it is important that you check how it works
in a safe and calm place. As an e-drive user, you decide which routes you can manage as far
as your driving ability and physical ability are concerned. Before using e-drive, make sure
that the tyres are not worn or damaged and that the batteries are fully charged. These safety
checks and your driving abilities are important when assessing whether you can get around
using e-drive in the following places:
•Quays, landing sites and moorings, roads and locations by watercourses, jetties and
dams without protective rails.
•Narrow roads, slopes (e.g. ramps and approaches), narrow roads close to precipices,
mountainous areas.
•Narrow and/or steep/sloping paths by busy roads or near to precipices.
•Leaf- and snow-covered or icy stretches.
•Ramps and lifting devices.
Warning
With e-drive you can manage uphill and downhill slopes in accordance with the wheelchair
manufacturer's specifications. The basic prerequisites are tyres that are not worn, the correct
tyre pressure, a risk-free surface and a maximum user weight of 120 kg.
You will need help when you have to negotiate:
•Kerbs requiring the wheelchair to tilt by over 15%.
•All kinds of obstacle more than 50mm, on slopes, as the risk of overturning then
increases.
•When you exceed the turning radius of 1600 mm
Be extremely careful when crossing busy roads and at railway and other crossings. Never
drive parallel to tram and railway tracks when trying to cross them, as there is a risk of the
wheels getting stuck in the tracks. It's better to get someone to help you who can quickly push
the wheelchair over the street or railway crossing if the wheelchair suddenly stops (e.g. if the
batteries have no charge).
Be careful when driving up ramps onto vehicles. When lifting and lowering, e-move must be
disconnected and the parking brakes must be activated.
On wet surfaces the tyres have less grip on the road and there is an increased risk of skidding.
Always adjust your driving to the situation at hand.

TRANSPORT AND DISASSEMBLY
Your e-drive is easy to get ready for transport.
Battery
1. Remove the battery by pressing button (A) whilst carefully pulling the battery out of
its holder (Figure l).
Cable
2. Remove the cable from the socket by turning it whilst pulling it carefully upwards
(Figure 2).

Wheels
The wheels are removed by pressing the button.Picture1and 2pull straight
outward.
Take care when removing the right-hand wheel. The battery holder and switch can
easily start to rotate if you do not hold one of them whilst loosening the wheel. Be
carefully with the e-drive wheels when you transport them so they don’t become
exposed for any hits or knocks.
If you should transport the wheelchair with the e-drive installed, do not hold the
pushrim, battery or cable when lifting the wheelchair. This may cause damage to the
unit.
