Product Overview

3.1 Intended Use
3.1.1 Intended User
This mobility device was designed for adults and adolescents whose ability to walk is impaired, but who are still in terms of their eyesight and physically and mentally able to operate an electric mobility device.
3.1.2 Indications
The use of this power wheelchair is recommended for the following indications:

• The inability or a greatly restricted ability to walk within the scope of the basic requirement to be able to move within one’s own four walls.
• The need to leave the dwelling place in order to get some fresh air during a short walk or to reach those places generally to be found at close distance to the dwelling and where everyday business is carried out.
  Provision of power wheelchairs for interior and exterior areas is advisable if the use of hand-operated wheelchairs is no longer possible on account of the disability, yet proper operation of an electromotive drive unit is still practicable.

Contraindications
There are no contraindications known.

3.5 User Inputs
Your mobility device may be fitted with one of several different user inputs. For information on the different functions and how to operate a particular user input, refer to its corresponding user manual (enclosed).
3.6 The Lifter
The electric lifter is operated from the remote. Refer to the remote manual for more information.
Information regarding operation of the lifter at temperatures of less than 0 °C

• Invacare mobility devices are fitted with safety mechanisms that prevent capacity overload of the electronic components. At operating temperatures below freezing point this can, in particular, lead to the lifter actuator being shut down after approx. 1 second operating time.
• The lifter can be raised or lowered gradually by repeatedly operating the joystick. In many cases this generates sufficient heat for the actuator to operate as normal.

Speed limiter
The speed limit reacts in different ways, depending on the mobility device’s configuration.

• Either the lifter is fitted with sensors which reduce the mobility device’s speed as soon as the lifter is raised above a certain point.
• Or if the speed limit is activated, a reduced drive level (forced profile) is set automatically. Refer to the remote manual for more information.
• The speed reduction takes place to guarantee the tipping stability of the mobility device and to avoid personal risk and damage to the mobility device.
• To reapply normal speed, lower the lifter down until the forced profile or the speed reduction switches off.
• If the mobility device is fitted with a chin control, it reacts different to forced profile. Refer to the manual of the chin control for more information.

CAUTION!
Risk of tipping, if the speed limiter sensors fail when the lifter is raised
– If you find that the speed reduction function is not working when the lifter is raised, do not drive with the lifter raised and immediately contact an authorized Invacare provider.

Accessories/Options

4.1 Posture Belts
A posture belt is an option which can either be fixed to the mobility device ex-works or can be retrofitted by your specialist provider. If your mobility device is fitted with a posture belt, your specialist provider will have informed you about  fitting and usage.
The posture belt is used to help the mobility device user keep an optimum seating position. Correct use of the belt assists the user in sitting securely, comfortably and well-positioned in the mobility device, especially for such users who do  not have such a good sense of balance while sitting.
We recommend using the posture belt whenever the mobility device is used.
4.1.1 Types of posture belts
Your mobility device can be fitted with the following posture belt types ex- works. If your mobility device has been fitted with a different belt to those listed below, please ensure that you have received the manufacturer’s documentation with regard to correct fitting and use.
Belt with metal buckle, adjustable both sides

Belt can be adjusted on both sides. This means that the buckle can be centrally positioned.
Belt with plastic buckle, adjustable both sides

Belt can be adjusted on both sides. This means that the buckle can be centrally positioned.
Harness with metal buckle, adjustable on both sides

Harness can be adjusted on both sides. This ensures that the buckle is always centrally positioned.
4.1.2 Adjusting Posture Belt Correctly
The belt should be tight enough to ensure that you are sitting comfortably and that your body is in the correct sitting position.

1. Ensure that you are sitting correctly, which means that you are sitting right at back of seat, your pelvis is positioned erect and as symmetrically as possible, not to front, to side or at one edge of seat.
2. Position posture belt so that your hipbones can be easily felt above belt.
3. Adjust belt length using one of adjustment aids described above. The belt should be adjusted so that you can fit a flat hand between belt and your body.
4. Buckle should be positioned as centrally as possible. In doing so, carry out adjustments on both sides as much as possible.
5. Check your belt every week to ensure that it is still in good working condition, to ensure it has no damage or wear, and that it is fixed properly to mobility device. If belt is only fastened with a bolted connection, ensure that  connection has not loosened or come undone. You can find more information about maintenance work on belts in the service manual, which is available from Invacare.
