SAFETY - Seat b. There should be less than one inch (25 mm) gap between the body and the belt. c. The shoulder belt must be positioned over the shoulder, it must never rest against the neck or be worn under the arm. d. Make sure any slack is wound up on the retractor and that the belt is not twisted. If the belt is locked, lean the body back to remove any tension in the belt. After releasing the belt, allow the belt to retract completely by guiding the belt tongue until the belt comes to a stop. To unfasten the belt, push the release button on the buckle and the belt should spring out of the buckle. The seat belt indicator will turn off once the driver's seat belt is fastened.
1 WARNING DO NOT remove, modify, or replace the tether belt system with a different tether system. A failed or missing teth- er belt could allow the seat base to fully extend in the event of an acci- dent. Failure to comply may result in death or personal injury. WARNING Failure to adjust external tether belts properly can cause excessive move- ment of the seat in an accident. Tether belts should be adjusted so that they are taut when the seat is in its most upward and forward position. Failure to comply may result in death or per- sonal injury. Tether Belts Make sure that the tether belt is attached to the cab floor and seat frame. It should be routed through the buckle on each side.
Often the attachments are made using a split-type hook. Make sure both halves of the hook are around the anchor bracket. Adjust an external tether by either lengthening or shortening the strap. To lengthen it: 1. Turn the buckle to a right angle to the webbing. 2. Then pull the buckle. Y53-6126-1A1 (01/21) 29
