1   There is a black lever on both sides of the heel unit. Push it in the down position. This releases the heel to slide back and forth. 

2   Move the heel back and hold the boot toe all the way into the toe piece. 

3   Slide the heel unit all the way forward until it firmly touches the heel of the boot. 

4   Release the lever to lock the heel unit. 

5   Click the boot into the binding. (See photo)

6   At the rear of the heel unit, you will see a slotted metal tang. Under that tang is a small metal tab with multiple small groves. With the boot in the binding, the slotted metal tang should be aligned over any of the groves located on the metal tab. 

7  If all the groves are covered by the tang, the binding should moved one letter forward until #10 is accomplished. 

8  If all the groves are exposed, move the heel unit back one letter until #10 is accomplished. 

9  Both heel units should be on the same letter. Remember that letter in case someone else tries the skis. 

10  Now adjust the DIN setting on the toe and heel units to the same number. You should ask a ski shop for that number. The wrong DIN setting could result in premature release, or no release; either scenario could result in injury. You can use the number from your old skis if it held ok. All bindings should have the same DIN number system.
