Familiarize yourself with the wheelchair’s performance capacity gradually and on different terrains,
such as sand, snow, ice, off-road paths etc. to find the correct adjustments, speeds and ways of
steering for different situations. Drive practice is also necessary for learning safe and flexible use of
the wheelchair in different driving situations. It is especially important to learn the correct use of the
balance adjustment system. Start practicing at a low maximum speed, when it is easier to control
the wheelchair. As the wheelchair has four motors and four-wheel steering, its capacity is great and
therefore utmost caution should be applied in the beginning.
The speed and direction of the wheelchair is adjusted by the joystick. By pushing the joystick
forwards or backwards, the wheelchair moves to the direction determined by the current wheel
position. If the wheels are turned so that the right side wheels are close to each other (picture 2),
the wheelchair will move forward to the right when the joystick is pushed forward (Picture 3A) and
backwards to the right by pulling the joystick backwards (Picture 3b).
The driving direction is corrected by moving the joystick sideways. After this, keep pushing the
joystick straight forward and make only small sideways movements until the correct drive direction is
found. Avoid extreme movements and start driving slowly to find the correct feel. If the wheelchair
moves in an undesired way, release the joystick. This stops the wheelchair in all situations. In
emergency situations switch the driving controller off. When you have learned how to use the
wheelchair on a level surface, you can start practicing how to negotiate obstacles and hills, where it
is essential to master the balance adjustment system.
