  • Page 33: Using The Joystick To Drive The Wheelchair

    Using the Joystick to Drive the Wheelchair NOTE: For this procedure, refer to FIGURE 5.2. The joystick is located on the joystick housing and 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 wheelchair to move in that direction.  The joystick has proportional drive control, meaning that the further it is pushed from the  upright (neutral) position, the faster the wheelchair moves. The maximum speed,  however, is limited by the setting of the speed‐control knob. To slow the wheelchair to a stop, simply release the joystick. The wheelchair has  automatic speed and direction compensation to minimize corrections. When first learning to drive, select a slow speed and try to drive the wheelchair as slowly  as possible by pushing the joystick slightly forward. This exercise will help you learn to  utilize the full potential of the proportional control and allow you to start and stop  smoothly. To drive the wheelchair, perform the following: 1. Adjust speed control knob to the appropriate setting. 2. Turn the power On. Refer to Turning the Power On/Off on page 32. 3. Maneuver the joystick in the following manner: MOVEMENT ACTION FORWARD Push joystick forward, towards the front of the wheelchair. REVERSE Pull joystick back, towards the rear of the wheelchair.

Plug the charger’s AC power cord, or extension, into the grounded 120 VAC wall  outlet. 3. Wait until charging is complete. NOTE: Allow eight hours for normal charging. Larger batteries (greater than 55 ampere‐hours) or  severely discharged batteries may require up to sixteen hours to be properly charged and equalized. NOTE: It is advantageous to recharge frequently rather than only when necessary. In fact, a  battery’s life is extended if the charge level is maintained well above a low condition. NOTE: If the batteries need to be charged more often or take longer to charge than normal, they  may need to be replaced. Contact an Invacare dealer for service.
