CAUTION:
● For your safety, when you use the wheelchair for the first few times, KARMA
strongly recommends you to use the rear position which provides the
maximum axle distance. The setting will help you to avoid potential dangers
until you are fully comfortable with your wheelchair. Once you are
comfortable with the setting, you can shorten the distance between the
front and rear wheels according to your demand.
