*1 Minimum Reversing Space is the space required to pivot on a spot and is determined by the wheelchair frame.
*2 The value is the load capacity for the JWX-2. When the wheelchair is completely assembled, the total weight of the rider and luggage must not exceed the
load capacity of the wheelchair frame.
If the wheelchair is operated continuously with a load that exceeds this value, the product could malfunction or be damaged, or its life could be shortened.
*3 The travel range varies depending on the conditions of the road surface (travel over curbs, on slopes, and so on) and may be shorter than this value.
