DANGER - Immediately imminent danger
If not avoided, this will result in death or severe bodily injuries!
WARNING - Possible imminent danger
If not avoided, this may result in death or severe bodily injuries!
CAUTION - Possible imminent danger or harmful situation
If not avoided, this may result in minor bodily injuries or damage to property!
iNOTE - Information by the manufacturer
General safety instructions
iNOTE
If you have a visual disability, this user manual can be downloaded at:
www.aat-online.de/bda/max-e_black_edition.
Read the user manual prior to start-up and observe the warning notices and safety instructions.
In the event of reading disabilities, cover training content in more depth verbally.
The user manual must be kept in a safe place after reading through it.
It does not consist exclusively of ame retardant substances. Keep max-e away from sources of
ignition.
max-e can interfere with highly sensitive electromagnetic elds of other electronic devices
(e.g. anti-theft devices).
Stability tests were performed under laboratory conditions. max-e may behave di󰀨erently under real
conditions compared to laboratory tests.
Training may only be carried out by the manufacturer, the AAT eld sta󰀨 or the qualied specialist shop.
CAUTION
External heat sources may cause the surface temperature to rise (e.g. sunlight)!
Do not touch the a󰀨ected surfaces in this case to avoid burns!

2 Explanation of the symbols on the packaging
WARNING / RISK OF CRUSHING
Never touch rotating/moving parts (e.g. engagement of gear wheel in the toothed ring),
to prevent crushing.
DANGER
max-e must not be operated in the case of severe visual impairment and/or blindness!
Do not exceed the total permissible weight and the maximum person weight, as this may lead to
defects or an overloading of max-e!
Avoid driving in heavy rain, ice, snow and on unsurfaced ground (sand, mud, loose crushed rock) to
prevent slipping!
Do not use on escalators or travellators to avoid injuries caused by a crash or the falling out of the
occupant and the occurrence of damage to property!
The operational capability of max-e can be inuenced by electromagnetic elds
(e.g. by mobile phones, electric generators or high-voltage sources)!
Do not store near medical devices, for example with a life support function,
and diagnostic devices, as these may malfunction!

4.2 Indication and intended use
The max-e is an electrical transport device and is attached to a manual wheelchair. The objective of the
electrical transport device is to make movement with a manual wheelchair easier for a self-propelled
person and to take over the force generation for the movement of the wheelchair. This shall maintain
autonomous movement and increase mobility and exibility for the patient.
The max-e drive can optionally be equipped with a control unit for use by an accompanying person.
This applies to the following indication:
If the wheelchair user does no longer have the motor ability to move the wheelchair by himself/herself by
operating the joystick control, and the strength of the accompanying person is not enough to steer and/
or push and brake a person sitting in the wheelchair.
The max-e can be used indoors as well as outdoors.
4.3 Contraindication
The max-e must not be used if:
• the operator has obtained no training/instruction for the product
• the operator is not physically and mentally able to operate the max-e safely
• more than one person shall be transported simultaneously
• the operator does not have adequate eyesight
• the braking e󰀨ect is lost due to rain, wet conditions, snow or black ice
• the braking e󰀨ect of the max-e does not set in
• escalators or travelators shall be overcome
• medical devices with e.g. a life support function, and diagnostic devices are in the proximity
• it is not used according to the intended use
• objects shall be transported

5.5 Anti-tip supports
WARNING - Never use without both anti-tip supports to prevent the wheelchair from tipping
backwards!
WARNING - Check the anti-tip supports before initial operation to ensure safety!
If anti-tip supports are not available on your wheelchair as standard, use AAT anti-tip supports in pairs!
The wheelchair bracket determines which anti-tip supports you require. The type of holder you should
attach to your wheelchair depends on the model of your wheelchair.
Option 1: Bracket with locking bolts
Remove bracket locking
bolts.
Push the anti-tip support into
the bracket and secure with
the locking pin.
Observe the “R” + “L”
markings! Repeat process

the bracket and secure with
the locking pin.
Observe the “R” + “L”
markings! Repeat process
on the other side.
DANGER - Operation only by a single, trained person. This person must be physically and
mentally able to safely operate max-e and may not su󰀨er from cognitive impairments!
DANGER - Never use without both anti-tip supports to prevent the wheelchair from tipping
backwards!
DANGER - Avoid parallel journeys on steep hillsides or rails, to prevent the wheelchair from
overturning!
DANGER - Cross over roads, crossroads and railway crossings with increased caution!
DANGER - Avoid driving on slopes with max-e disabled, as there is no braking e󰀨ect when
doing so!
DANGER - Do not use on escalators or travellators to avoid injuries caused by a
crash or the falling out of the occupant and the occurrence of damage to property!
WARNING - Practise outdoors on a level surface and at low speed!
WARNING - Drive down slopes at the lowest speed to avoid dangerous situations!
WARNING - Do not drive up stairs or steps to prevent the wheelchair from overturning!
WARNING - Avoid driving in heavy rain, ice, snow and on unsurfaced ground
(sand, mud, loose crushed rock) to prevent slipping!
WARNING - During driving breaks, when using local transport (busses, trams, etc.)
and when transferring, switch max-e o󰀨 and apply the parking brakes to prevent the
wheelchair from rolling away!
WARNING - When driving on public roads, observe the road tra󰀩c regulations!

17
CAUTION - Always overcome kerbs/obstacles backwards (see chapter 6.4)!
CAUTION - Maintain su󰀩cient distance to the edge of the kerb to avoid damage!
CAUTION - When using seat supports (cushions, etc.), ensure that the occupant is
securely seated to prevent the occupant from falling out or slipping!
iNOTE - Never drive backwards on walls with the anti-tip supports mounted so as not to
damage the anti-tip supports.
WARNING - Never touch rotating/moving parts (e.g. engagement of gear wheel in the toothed
ring), to prevent crushing.
WARNING - If the drive elements become blocked or when the driving behaviour
has been altered, switch o󰀨 max-e immediately and do not use it!
WARNING - Observe the maximum permissible weight (see chapter 4.4)!

Emergency release button
Unplug power lead (if
necessary, apply the parking
brake beforehand).
Press the emergency release
button. Pressure reduces and
the drive shafts retract.
Emergency stop function
If, while moving (joystick deected), the user presses the OFF button, the drive stops immediately
and an acoustic warning signal sounds.
• If the OFF button remains pressed, the “switch-o󰀨 notice” appears after approx. 2 seconds. The
switch-o󰀨 can be conrmed via the PLUS button. The drive is switched o󰀨.
• If the user acknowledges the “switch-o󰀨 notice” via the MINUS button, the drive remains switched
on and standing still.
• To be able to continue moving, the joystick must rst be brought to neutral position.
If the user releases the OFF button again before the 2 seconds have expired, the following will
occur:
• The drive remains standing still.
• To be able to continue moving, the joystick must rst be brought to neutral position
Standby function
• One minute prior to reaching the set switch-o󰀨 time, a "warning notice" appears on the display and
the acoustic "warning signal" sounds
• The backlight is switched on
• By deecting the joystick or by pressing the PLUS or the MINUS or the HORN button, the
warning notice will disappear again
• The timer starts again
• If the joystick is deected or one of the buttons is pressed before the “warning notice” appears,
the timer starts again
Switch-o󰀨
• When reaching the set switch-o󰀨 time, the "switch-o󰀨 notice" appears
• The acoustic "warning signal" sounds
• The backlight is switched on
• Then, the user can conrm the switch-o󰀨 via the PLUS button
• Then, the drive is switched o󰀨
• If the user acknowledges the "switch-o󰀨 notice" via the MINUS button, the drive remains
switched on and the standby timer starts again
Reminder
• If the switch-o󰀨 is not acknowledged:
• the acoustic “warning signal” sounds every minute
• the backlight is switched on
» Wheelchair can be moved
