6. Insert metal retainer in the new buckle slot position.

SECURING YOUR CHILD
1. Pull up on buckle strap to make sure it is secured.
2. Pull all the slack out from around the waist. Pull up on
the harness strap while pushing the chest clip down. Do
this to both sides.
3. Tighten the harness by pulling the harness adjustment
strap. When you are not able to pinch any of the harness
webbing at your child's shoulder, the harness is tight
enough. A snug harness should not allow any slack. It
lies in a relatively straight line without sagging. It does
not press on the child's flesh or push the child's body
into an unnatural position.
4. Buckle the chest clip. You will hear
a "click" when the chest clip is
securely buckled.
5. Place the chest clip at armpit level.
