Marker Rail Ski Bindings are designed to facilitate adjustments of the toe piece, heel piece and the length within the bindings. The toe and heel pieces are adjusted to a tension referred to as the DIN setting, which accounts for the weight of the skier and the level of expertise. Typically, a novice skier would have a lower DIN setting, and an aggressive skier a higher DIN setting to maintain the ski boots in the bindings. The Fore/Aft adjustment is used to move the bindings forward or back on the rails. Adjusting Marker Rail Ski Bindings begins with establishing the DIN number.
Obtain a DIN chart and calculate the DIN number by correlating your weight and experience level with the data on the chart. Follow the calculation steps as given in the instructions. Note the results of the calculations to determine your DIN setting.
Locate the DIN adjustment screws and the visual indicators on the right and left skis. You will find the screws in the front of the toe piece and behind the heel piece. Use a screwdriver to turn the adjustment screws on the right ski while observing the indicator. Adjust the toe and heel of the binding to your DIN setting. Repeat this step with the left ski binding.
Put your ski boots on and check the Fore/Aft setting by inserting the toe of your right boot into the toe clip on the right ski. Step down with your heel and note the amount of pressure needed to seat your right boot into the binding. Loosen the pair of small screws atop the rails and adjust the binding to a point where the boot fits securely and tighten the screws. Repeat this with your left boot and left ski.
Step into the binding on the right ski. Twist your ankle to the right and left on a lateral plane to check the tension on the toe piece. Stabilize the ski with one hand and use the palm of your other hand to hit the side of your boot near the toe to further test the tension. Repeat this with the left ski and make any minor adjustments as desired.
Contact the manufacturer for information on obtaining a DIN chart.
Avoid overextend the Fore/Aft adjustment because this could make the binding insecure on the rails.
