SECTION 1—GENERAL GUIDELINES SECTION 1—GENERAL GUIDELINES WARNING SECTION 1 - GENERAL GUIDELINES contains important information for the safe operation and use of this product. Controller Settings/Repair or Service Set‐up of the Electronic 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.
SECTION 1—GENERAL GUIDELINES 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 a water, ice or oil film. DO NOT attempt to drive over curbs or obstacles. Doing so may cause your wheelchair to turn over and cause bodily harm or damage to the chair. DO NOT leave the power button in the On position when entering or exiting your wheelchair. DO NOT stand on the frame of the wheelchair.
SECTION 1—GENERAL GUIDELINES M61 Wheelchairs Only DO NOT operate wheelchair on an incline while in an elevated position. Otherwise, the wheelchair may tip over and injury or damage may occur. Batteries The warranty and performance specifications contained in this manual are based on the use of deep cycle gel cell or sealed lead acid batteries. Invacare strongly recommends their use as the power source for this unit.
SECTION 1—GENERAL GUIDELINES 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.
SECTION 2—EMI INFORMATION SECTION 2—EMI INFORMATION WARNING CAUTION: IT IS VERY IMPORTANT THAT YOU READ THIS INFORMATION REGARDING THE POSSIBLE EFFECTS OF ELECTROMAGNETIC INTERFERENCE ON YOUR POWERED WHEELCHAIR.
SECTION 2—EMI INFORMATION WARNING Powered Wheelchair Electromagnetic Interference (EMI) Because EM energy rapidly becomes more intense as one moves closer to the transmitting antenna (source), the EM fields from hand-held radio wave sources (transceivers) are of special concern. It is possible to unintentionally bring high levels of EM energy very close to the powered wheelchair's control system while using these devices. This can affect powered wheelchair movement and braking.
SECTION 3—SAFETY/HANDLING OF WHEELCHAIRS SECTION 3—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.
SECTION 3—SAFETY/HANDLING OF WHEELCHAIRS Coping With Everyday Obstacles WARNING DO NOT attempt to reach objects if you have to move forward in the seat or pick them up from the floor by reaching down between your knees. Proper positioning is essential for your safety. When reaching, leaning, bending or bending forward, it is important to use the casters as a tool to maintain stability and balance. Many activities require the wheelchair user to reach, bend and transfer in and out of the wheelchair.
SECTION 3—SAFETY/HANDLING OF WHEELCHAIRS A Note to Wheelchair Assistants When assistance to the wheelchair user is required, remember to use good body mechanics. Keep your back straight and bend your knees whenever tilting wheelchair or traversing curbs or other impediments. Also, be aware of detachable parts such as arms or legrests. These must NEVER be used to move the wheelchair or as lifting supports, as they may be inadvertently released, resulting in possible injury to the user and/or assistant(s).
SECTION 3—SAFETY/HANDLING OF WHEELCHAIRS WARNING Pinch point may occur when adjusting the arm angle position (Detail “A”). Pinch point may occur when rotating the footboard assembly (Detail “B”).
