￿ WARNING

ALWAYS perform these procedures in the presence of an assistant. The position of the footrest, camber tube, seat angle, 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-tippers may be required.
