    - otherwise, injury or damage may occur. Repair or Service Information Set‐up of the Electronics Control Unit is to be performed only by a qualified technician.  The final adjustments of the controller may affect other activities of the wheelchair.  Damage to the equipment could occur if improperly set‐up or adjusted.  Except for programming, DO NOT service or adjust the wheelchair while occupied,  unless otherwise noted. A pinch point exists between head tube cap and walking beam.  A pinch point exists between walking beam/head tube cap and telescoping tube when  TDX is at the lowest seat to floor height. Before adjusting, repairing or servicing the wheelchair, ALWAYS turn the wheelchair  power Off, otherwise, injury or damage may occur. Invacare products are specifically designed and manufactured for use in conjunction with  Invacare accessories. Accessories designed by other manufacturers have not been tested  by Invacare and are not recommended for use with Invacare products. Transport ready packages are not retrofittable to existing models and are not field  serviceable.  Battery retention brackets MUST be installed at all times. Otherwise, the wheelchair will  not be WC/19 compliant. Refer to Removing/Installing the Batteries From/Into the  Wheelchair on page 57. Wheelchairs should be examined during maintenance for signs of corrosion (water  exposure, incontinence, etc.). Electrical components damaged by corrosion should be  replaced IMMEDIATELY. Wheelchairs that are used by incontinent users and/or are frequently exposed to water  may require replacement of electrical components more frequently.

  • Page 16: Operation Information

    SECTION 1—GENERAL GUIDELINES Operation Information Performance adjustments should only be made by professionals of the healthcare field or  persons fully conversant with this process and the driverʹs capabilities. Incorrect settings  could cause injury to the driver, bystanders, damage to the wheelchair and to  surrounding property. After the wheelchair has been set‐up/adjusted, check to make sure that the wheelchair  performs to the specifications entered during the set‐up procedure. If the wheelchair does  NOT perform to specifications, turn the wheelchair Off immediately and reenter set‐up  specifications. Repeat this procedure until the wheelchair performs to specifications. DO NOT leave the power button On when entering or exiting your wheelchair. DO NOT attempt to drive over curbs or obstacles greater than 3 inches. Doing so may  cause your wheelchair to turn over and cause bodily harm or damage to the wheelchair.  ALWAYS stop before climbing an obstacle. Approach slowly until casters contact the  obstacle. Apply power and the action of the SureStep feature will lift the casters over the  obstacle. Weight is transferred to the drive wheels providing traction and motor strength  to power the wheelchair over the obstacle. DO NOT operate on roads, streets or highways. DO NOT climb, go up or down ramps or traverse slopes greater than 9°. DO NOT attempt to move up or down an incline with water, ice or oil film. DO NOT stand on the frame of the wheelchair. DO determine and establish your particular safety limits by practicing bending, reaching  and transferring activities in the presence of a qualified healthcare professional before  attempting active use of the wheelchair. DO NOT attempt to reach objects if you have to move forward in your seat.  DO NOT attempt to reach objects if you have to pick them up from the floor by reaching  between your knees. DO NOT lean over the top of the back upholstery to reach objects behind you, as this may  cause the wheelchair to tip over. ALWAYS shift your weight in the direction you are turning. DO NOT shift your weight  in the opposite direction of the turn. Shifting your weight in the opposite direction of the  turn may cause the inside drive wheel to lose traction and the wheelchair to tip over. DO NOT shift your weight or sitting position toward the direction you are reaching as the  wheelchair and/or seating system (if any) may tip over. DO NOT use an escalator to move a wheelchair between floors. Serious bodily injury may  occur. DO NOT use the footplates as a platform. When getting in or out of the wheelchair, make  sure that the footplates are in the upward position or swing footrests towards the outside ...

  • Page 36 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 35. 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.
