    WARNING:
    • When the lap pre-tensioner seat belt operates (deploys), the piston ejects from the end of the cylinder. If an object lies in the ejection path within 40 mm of the cylinder end, the piston could hit the object, rebound and hit the lap pre-tensioner seat belt. The force of the piston hitting the lap pre-tensioner seat belt could dislodge it from the vice and cause injury. When securing the lap pre-tensioner in the vice, position it so that there is no obstruction in the ejection path within 40 mm of the cylinder end.
  6. Secure the lap pre-tensioner seat belt in the vise with a wire (cross section of 1.25 mm 2 {0.002 in 2) or more) through the shaft of vice and the lap pre-tensioner seat belt bracket hole at least 4 times.
