*2 When the wheelchair is completely assembled, the 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.

value.
*4 This is the available temperature range. Confirm the recommended temperatures for "8.3." and "9.3."
