General safety instructions
•To avoid falls and accidents, it is important to familiarize yourself with your new wheelchair in a
safe environment, on a level surface. We recommend to bring in a companion at the beginning.
•When adjusting and the wheelchair there is a risk of entrapment for the user as well as for third
persons who are in the immediate vicinity of the wheelchair.
•Avoid driving against steps or curbs.
•When transporting the wheelchair, it must be secured against rolling away. Use the fastening
devices.
•In the event of prolonged exposure to the sun, parts of the wheelchair may heat up, there is a risk of
burns.
•Weight transfer due to body movement or load may increase the risk of tipping.
•Please do not hang objects such as carrying bags, backpacks etc. on the wheelchair, this is not
intended. Attached loads, change the statics and can lead to falls and modified braking behavior.
•When driving on uphill or downhill gradients, make sure that the seat surface is not raised as this
will limit the stability and can cause the wheelchair to fall over.
•Note that the braking distance is longer on inclines than on level ground.
•When overcoming slight obstacles or height differences, you should raise the seat slightly, if at all,
and leave the backrest as steep as possible to prevent the wheelchair from tipping over.
•Do not bring damaged batteries into contact with skin, as the contents of the battery are harmful to
health and can be corrosive.
•Only charge the battery in ventilated areas.
