General safety instructions
iNOTE
If you have visual impairment, this user manual can be downloaded at:
www.aat-online.de/de/bda/SOLO .
Read the user manual prior to start-up and observe the warning notices and safety instructions.
In the event of reading di󰀩culties, training contents must be broadened verbally.
The user manual must be kept in a safe place after reading through it.
Contains some ammable materials. Keep SOLO away from sources of ignition.
SOLO can interfere with highly sensitive electromagnetic elds of other electronic devices
(e.g. anti-theft devices).
Stability tests were performed under laboratory conditions. SOLO can 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!

Symbol Explanation
Handle with care
The packaging including the product must be handled with special care.
Protect from moisture
Protect the packaging including the product from overly high air humidity.
Cover during storage. Carefully cover with a tarpaulin, if necessary.
Caution fragile
Handle the packaging including the product carefully and never allow it to fall.
This way up
The packaging must be stored and transported in such a way that the arrows
point upwards at all times. Any failure to comply with this rule, such as rolling
or tilting the package, must be avoided.
2 Explanation of the symbols on the packaging
WARNING
To avoid being crushed, never reach into rotating/moving parts!
DANGER
SOLO 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 SOLO!
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 SOLO 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 SOLO transport device allows those who have limited mobility, or disabled people that are no longer
able to use a manual wheelchair using their own residual force, to move around independently.
The SOLO transport device is also equipped with an operating unit that can be used by an accompanying
person. This feature is important when the wheelchair user is no longer able to move around themselves
using the joystick and the accompanying person’s own strength does not allow them to push a wheelchair
along with the wheelchair user in it. The accompanying person of a single person in a wheelchair is
supported both on even surfaces as well as on upward/downward slopes. The SOLO transport device
may be used indoors as well as outdoors.
The SOLO transport device has been developed to be operated by one person using the joystick or from
an accompanying person using the operating unit. These people must be trained, and be physically as
well as mentally able to safely operate the SOLO transport device! They must have su󰀩cient vision
capability!
Please bear in mind that using the SOLO transport device may entail a greater degree of risk and
requires more skill than that required to operate/use a manual wheelchair.
The life expectancy of SOLO depends on the intensity of the application and is approx. 5 years under
normal use. This statement implies compliance with all prescribed maintenance and service specica-
tions. The life expectancy can also be exceeded with careful handling. However, this life expectancy can
also be shortened due to overuse and improper handling.
4.3 Contraindication
SOLO may not be used if:
• the operator has not received training/instruction for the product!
• the operator is physically and mentally unable to safely use SOLO!
• more than one person needs to be transported at the same time!
• the operator does not have su󰀩cient ability to see!
• the braking e󰀨ect is lost due to rain, wet conditions, snow or ice!
• a braking e󰀨ect of SOLO is not achieved!
• escalators or travellators must be negotiated!
• medical devices, for example with a life support function, and diagnostic devices, are nearby!
• the intended use is contradicted!
• objects are to be transported!

6 Start-up
DANGER - Operation only by a single, trained person. This person must be physically
and mentally able to safely operate SOLO 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 SOLO 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 – 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 brakes, when using local transport (busses,
trams, etc.) and when transferring, switch SOLO o󰀨 and apply the parking brakes
to prevent the wheelchair from rolling away!
WARNING – Drive down slopes at the lowest speed to
avoid dangerous situations!
WARNING – When driving on public roads, observe the road tra󰀩c regulations!
WARNING – Practise outdoors on a level surface and at low speed!
WARNING – Never reach into rotating/moving parts to avoid being crushed!
WARNING – If the drive elements become blocked or when the driving behaviour
has been altered, switch o󰀨 SOLO immediately and do not use it!
WARNING - Observe the maximum permissible weight (see chapter 4.4 / 4.5)!
CAUTION – Always overcome kerbs/obstacles backwards (see chapter 6.5)!
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.
