ALWAYS perform this procedure in the presence of an assistant. The position of
the footrest, camber tube, back angle, the tautness of the back upholstery as well as
the user's condition are directly related to the wheelchairs stability. Any change to
one or any combination of the five may cause the wheelchair to decrease in stability.
Use EXTREME caution when using a new seating position. The addition of anti-tip-
pers may be required.
