  • Page 15: Batteries

    SECTION 1—GENERAL GUIDELINES Before attempting to transfer in or out of the wheelchair, every precaution should be  taken to reduce the gap distance. Turn both casters parallel to the object you are  transferring onto. Also be certain the power is Off and wheel locks are engaged to prevent  the wheels from moving. DO NOT adjust the rear seat posts higher than the front seat posts. Before performing any maintenance, adjustment or service verify that On/Off switch on  the joystick is in the Off position. 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. If signs of wear appear, belt MUST be replaced  IMMEDIATELY. Avoid storing or using the wheelchair near open flame or combustible products. Serious  injury or damage to property may result. Batteries The warranty and performance specifications contained in this manual are based on the  use of deep cycle gel cell batteries. Invacare strongly recommends their use as the power  source for this unit. Carefully read battery/battery charger information prior to installing, servicing or  operating your wheelchair. DO NOT remove fuse or mounting hardware from POSITIVE (+) RED battery cable/ mounting screw. All battery terminal covers (two on the front battery and two on the rear battery) MUST  be installed prior to use. The use of rubber gloves is recommended when working with batteries. Some battery manufacturers mold a carrying strap and/or hold down flanges directly into  the battery case. Batteries that interfere with the battery box cannot be used for these  applications. Attempting to “wedge” a battery into a battery box may damage the box,  the battery and/or be a fire hazard, resulting in serious injury or further damage to  property. Charging Batteries DANGER When using an extension cord, use only a three wire extension cord having at least 16 AWG (American Wire Gauge) wire and the same or higher electrical rating as the devise being connected.

  • Page 16: Grounding Instructions

    DO NOT attempt to recharge batteries using BOTH the on‐board battery charger and an  independent battery charger (plugged into the joystick charger port) at the SAME time.  Doing so will reduce the life of the batteries. READ and CAREFULLY follow the manufacturer’s instructions for each charger  (supplied or purchased). If charging instructions are not supplied, consult a qualified  technician for proper procedures. AFTER charging batteries, ALWAYS make sure that the battery charger cord is securely  wrapped and stored within the hook and loop strap assembly on the rear of the battery  tray. Failure to do so may result in damage to the cord or personal injury to the user or  bystanders. Ensure the pins of the extension cord plug are the same number, size, and shape as those  on the charger. DO NOT under any circumstances cut or remove the round grounding plug from the  charger AC cable plug or the extension cord plug. Grounding Instructions DO NOT, under any circumstances, cut or remove the round grounding prong from any  plug used with or for Invacare products. Some devices are equipped with three‐prong  (grounding) plugs for protection against possible shock hazards and fire. Where a two‐ prong wall receptacle is encountered, it is the personal responsibility and obligation of the  customer to contact a qualified electrician and have the two‐prong receptacle replaced with  a properly grounded three‐prong wall receptacle in accordance with the National Electrical  Code. If you must use an extension cord, use ONLY a three‐wire extension cord having the  same or higher electrical rating as the device being connected. In addition, Invacare has  placed RED/ORANGE warning tags on some equipment. DO NOT remove these tags. Rain Test Invacare has tested its power wheelchairs in accordance with ISO 7176 “Rain Test.” This  provides the end user or his/her assistant sufficient time to remove his/her power  wheelchair from a rain storm and retain wheelchair operation. DO NOT leave power wheelchair in a rain storm of any kind. DO NOT use power wheelchair in a shower. DO NOT store power wheelchair in a damp area for an extended period of time.
