3.2 Safety instructions
• The e-motion wheels must be switched off before being attached to the wheelchair, being removed from the wheelchair, and before
starting work on the wheelchair or the wheels themselves.
• For safety reasons, you must activate the parking brakes of your wheelchair when you stop, especially on uphill and downhill slopes,
in order to prevent the wheelchair from rolling away inadvertently.
• In the (unlikely) event of the battery overheating or catching on fire, you must ensure that the battery does not come into contact
with water or other liquids. The only suitable extinguishing agents recommended by the battery manufacturers are sand or a Class D fire
extinguisher.
Before beginning your journey:
• The e-motion may only be attached to push rim wheelchairs that have been approved by Alber GmbH for this device.
• The bracket holding the e-motion in place may only be installed and modified by Alber GmbH or an Alber authorised specialist dealer.
• When using the e-motion, always strictly adhere to the operating manual for the wheelchair.
• Driving the wheelchair without a pair of anti-tippers attached is not permitted.
• Attach anti-tippers to your wheelchair in pairs.
• Before each journey, check the e-motion wheels. If the tyres have reached their wear limit (if you can no longer see the tread),
the e-motion must no longer be used.
• Before every journey, check that your wheelchair parking brakes are working correctly. It is forbidden to drive the wheelchair without
working parking brakes.
• Check the air pressure of the e-motion wheels at regular intervals. For specifications, please refer to the table in chapter 16. Please
check the air pressure of the front wheels in accordance with the instructions and specifications of the wheelchair manufacturer. Insuffi-
cient air pressure can severely affect the handling and range of the wheelchair.
• Both e-motion 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 that the e-motion wheels are seated correctly in the two wheel retainers on your wheelchair.
• The e-motion may be used in conjunction with a wheelchair towing device or handbike up to a maximum speed of 20 km/h. Higher
speeds may damage the electronic systems of the e-motion drive wheels.
Always observe the following rules when travelling using the e-motion:
• Before using the e-motion to travel on a slope, practice operating the device on level ground.
• The maximum permissible slope specified by the wheelchair manufacturer must not be exceeded.
• Be very careful when approaching steps and drops.
• While the e-motion is switched on, each push you give to the push rims will be 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 on ramps of any type),
secure your wheelchair using its parking brakes and do not touch the push rims.
• Never reach into the wheel when the e-motion is switched on.
• Do not insert or throw objects of any kind into an e-motion wheel, regardless of whether or not it is switched on.
• Never attach objects of any kind to the push rims. These could induce involuntary drive impulses.
• When driving on pavements, keep a safe distance from the kerb (preferably the width of the wheelchair).
• Avoid using the wheelchair on soft ground (e.g. loose chipping, sand, mud, snow, ice or deep puddles).
• Never leave the e-motion unattended, even if it is switched off.
• The e-motion may be adversely affected by strong electromagnetic fields, particularly in the vicinity of the push rim sensor.
• Under certain circumstances, the e-motion may interfere with other electrical equipment such as anti-shoplifting barriers in department
stores.
• You must not use the e-motion on escalators or moving walkways.
• When travelling at maximum speed, do not suddenly change your direction of travel to the left or right, as this could cause the wheel-
chair to tip sideways.
• Reduce your speed when turning a corner.
• If you intend to stop in your wheelchair on an uphill or downhill slope, your wheelchair must be parked facing across this slope (not up
or down) and the parking brakes must be activated.
• After every trip or when your wheelchair is idle, activate the parking brakes to prevent the chair from rolling away inadvertently.
• Never travel across downhill slopes.
• Never reach into the front wheels of your wheelchair or the spokes of the e-motion wheels when travelling.
• Apply the e-motion brake carefully according to your speed (i.e. not suddenly).
• When travelling in a vehicle, always sit in the vehicle’s installed seats with the appropriate restraint systems. Failure to comply with
this guideline may result in injury to you and your co-passengers in case of an accident.
• When travelling by vehicle, secure your wheelchair and the e-motion wheels according to the currently applicable statutory requirements
and legislation.
