Exercise caution when travelling downhill with a fully charged battery pack.
A fully charged battery and high speeds may lead to a reduction in speed or the system automatically cutting off.
Therefore, reduce your speed.
As far as possible, negotiate obstacles (e.g. kerbs) in reverse. Please refer to the wheelchair operating manual
for the maximum permitted obstacle height.
Caution: when negotiating obstacles in reverse, the Alber anti-tippers cannot be guaranteed to be fully func-
tional. For this reason, drive slowly and carefully in reverse until the wheels of your e-fix touch the obstacle.
Now carefully negotiate the obstacle. It is up to you to decide whether to enlist the help of another person.
In the event of a problem or error message, immediately contact your specialist dealer.
Observe the following safety instructions and hazard information.
3.3 Safety instructions
The system must be switched off at the control unit before the e-fix wheels are fitted to the wheelchair or removed. Similarly, the sys-
tem must be switched off before starting work on the wheelchair.
For safety reasons you need to activate the parking brakes of your wheelchair, especially on uphill and downhill slopes, to avoid the
wheelchair inadvertently rolling away.
In the (unlikely) event of the battery pack overheating or catching on fire, you must ensure that the battery pack does not come into
contact with water or other liquids. The only suitable extinguishing agent that is recommended by the battery manufacturers is sand.
Before using the device:
The e-fix must only be attached to push rim wheelchairs that have been approved by Alber GmbH for this device.
The bracket holding the e-fix in place may only be installed and modified by Alber GmbH or an Alber authorised specialist dealer.
When using the e-fix, always strictly adhere to the operating instructions of the wheelchair.
Driving the wheelchair without an attached pair of anti-tippers is not permitted.
Attach the original anti-tippers of the wheelchair manufacturer or the optional Alber anti-tippers to your wheelchair.
Before every journey, check the e-fix wheels. If the tyres have reached their wear limit (you can no longer see the tread), the e-fix must
not be used.
Before every journey, check that your wheelchair parking brakes are working correctly. You must not travel without functioning parking
brakes that are adjusted to the e-fix wheels.
Check the air pressure of the e-fix wheels at regular intervals. For details on the correct air pressure, see the outside of the tyres and
the table in chapter 9. Please check the air pressure of the front wheels in accordance with the instructions and specifications of the
wheelchair manufacturer. Too low an air pressure can greatly affect the driving behaviour and the range.
Both e-fix wheels should always have the same air pressure.
Both front wheels of the wheelchair should always have the same air pressure.
Before every journey, check the correct fitting of the e-fix wheels in the wheel receiver [13] of the two brackets [1].
The e-fix must not be used in combination with a wheelchair puller or hand bike, or other pulling devices. In these kinds of situations,
use your manual wheelchair wheels instead of the e-fix wheels.
When travelling with the e-fix, make sure that:
Before using the e-fix to drive up or down a slope, you practice operating the device on level ground.
The maximum permissible slope specified by the wheelchair manufacturer must not be exceeded.
Approach steps or drops extremely cautiously.
When the system is switched on, each touch of the joystick is converted into a drive command. When stopping or waiting in potentially
dangerous positions (e.g. while waiting at a traffic light, on uphill and downhill slopes or ramps of any type), do not touch the control
unit and secure your wheelchair using its parking brakes.
Never reach into the wheel when the e-fix is switched on.
Do not insert or throw objects of any kind into a switched on or off e-fix wheel.
Never attach objects of any kind to the e-fix wheels. This could cause damage.
When driving on pavements, keep a safe distance (preferably the width of the wheelchair) from the kerb.
Avoid using the wheelchair on soft ground (e.g. loose chipping, sand, mud, snow, ice or deep puddles).
