  • Page 18: Section 4-Safety/Handling Of Wheelchairs

    “Safety and Handling” of the wheelchair requires the close attention of the wheelchair  user as well as the assistant. This manual points out the most common procedures and  techniques involved in the safe operation and maintenance of the wheelchair. It is  important to practice and master these safe techniques until you are comfortable in  maneuvering around the frequently encountered architectural barriers. Use this information only as a “basic” guide. The techniques that are discussed on the  following pages have been used successfully by many. Individual wheelchair users often develop skills to deal with daily living activities that  may differ from those described in this manual. Invacare recognizes and encourages each  individual to try what works best for him/her in overcoming architectural obstacles that  they may encounter, however all warnings and cautions given in this manual MUST be  followed. Techniques in this manual are a starting point for the new wheelchair user and  assistant with “safety” as the most important consideration for all. Stability and Balance WARNING ALWAYS wear your seat positioning strap. The seat positioning strap is a positioning belt only. It is not designed for use as a safety device withstanding high stress loads such as auto or aircraft safety belts.

  • Page 19: Coping With Everyday Obstacles

    SECTION 4—SAFETY/HANDLING OF WHEELCHAIRS To assure stability and proper operation of your wheelchair, you must at all times  maintain proper balance. Your wheelchair has been designed to remain upright and  stable during normal daily activities as long as you do not move beyond the center of  gravity. DO NOT lean forward out of the wheelchair any further than the length of the  armrests. Coping With Everyday Obstacles NOTE: For this information, refer to FIGURE 4.1. Coping with the irritation of everyday obstacles can be alleviated somewhat by learning  how to manage your wheelchair. Keep in mind your center of gravity to maintain stability  and balance. While the walking beam allows you to traverse up to a 1‐inch bump or threshold,  stopping after the wheels cross the bump poses a problem. The chair cannot reverse over  the bump at this point. Continue forward and then turn around. While the wheelchair is designed for use  1-inch Bump primarily in and around the home, the  or Threshold provider should determine whether this  chair is suitable for the actual environment  the chair will be used in. FIGURE 4.1 Coping With Everyday DO NOT go down ramp at full speed.  Obstacles Some seat/back positions will cause  wheelchair to feel unstable. CAUTION Be aware of condition of ramp.

  • Page 31: Using The Joystick To Drive The Wheelchair

    SECTION 6—WHEELCHAIR OPERATION Using the Joystick to Drive the Wheelchair NOTE: For this procedure, refer to FIGURE 6.2. The joystick is located at the front of 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 speed control setting. 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 the speed. Refer to Speed Control Buttons on page 33. 2. Turn the power on. Refer to Turning the Power On/Off on page 30. 3.
