Interface
(1) Observe the maximum load according to the wheelchair manufacturer's information.
(2) The attachment width can vary further depending on the wheelchair model.
(3) The braking capacity / rated slope as well as the range according to ISO 7176-4 depend, among other things, on the weight of the person being trans-
ported, the ground, the terrain profile, the ambient temperature, etc. Attention: The values may vary depending on your own muscle strength!
(4) At temperatures below 0 °C the performance of the battery pack will decrease; therefore we recommend a storage temperature of at least 0 °C.
(5) The person weight on the type plate and in the technical data were calculated using an assumed wheelchair weight of 20 kg.
