Using the Joystick to Drive the Wheelchair

WARNING

DO NOT operate wheelchair on an incline while in an elevated position. Otherwise, the wheelchair may tip over and injury or damage may occur.

NOTE: For this procedure, refer to FIGURE 4.3 on page 34.

The joystick provides smooth control of speed and direction. It is equipped with 360 degrees of mobility for ease of operation. The joystick is spring-loaded, and automatically returns to the upright (neutral) position when released. Pushing the joystick in a given direction causes the chair to move in that direction.

The joystick has proportional control, meaning that the further it is pushed from the upright (neutral) position, the faster the wheelchair moves or the seat elevates/lowers. The maximum speed, however, is limited by the speed setting.

To slow the wheelchair to a stop, simply release the joystick. The wheelchair has automatic speed and direction compensation to minimize corrections.
