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!

General safety instructions
iNOTE
If you have a visual disability, this user manual can be downloaded at www.aat-online.de/de/bda/v-max.
Read the user manual prior to start-up and observe the warning notices and safety instructions.
In the event of reading difculties, training contents must be broadened verbally.
The user manual must be kept in a safe place after reading.
It does not consist exclusively of ame retardant substances. Keep v-max+away from sources of ignition.
v-max+ can interfere with highly sensitive electromagnetic elds of other electronic devices
(e.g. anti-theft devices).
Stability tests were performed under laboratory conditions. v-max+can behave differently under
real conditions compared to laboratory tests.
Training may only be carried out by the manufacturer, the AAT eld staff or the qualied specialist shop.
CAUTION
External heat sources may cause the surface temperature to rise (e.g. sunlight)!
Do not touch the affected 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
v-max+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 v-max+!
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 v-max+ 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 v-max+pushing and braking aid allows you to make a manual wheelchair mobile. The accompanying
person is thus relieved considerably of physical work. The v-max+pushing and braking aid effectively
broadens the range of motion for the user. v-max+is suitable for indoor and outdoor use.
v-max+is designed to be operated by only one person. This person must be trained and physically and
mentally able to safely operate v-max+! They must have sufcient vision capability! It needs to be borne
in mind that the use of a pushing and braking aid can entail a greater degree of risk and requires more
skills than those required to operate a wheelchair.
The life expectancy of v-max+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cations.
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
v-max+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 v-max+!
• more than one person needs to be transported at the same time!
• the operator does not have sufcient ability to see!
• the braking effect is lost due to rain, wet conditions, snow or ice!
• a braking effect of v-max+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!
