Setting up Marker bindings correctly is crucial for safety, performance, and the proper release of your skis in a fall. The process involves precise adjustments to ensure your ski boots fit securely and the binding releases appropriately based on your skill level and physical characteristics.
Understanding Your Marker Bindings
Marker bindings, like all ski bindings, are designed to hold your boot firmly to the ski while allowing for a safe release during certain forces, such as those encountered in a fall. Proper setup ensures the binding performs these functions reliably, preventing premature releases or, more dangerously, failure to release when needed.
Essential Tools for Binding Adjustment
Before you begin, gather the necessary tools:
- Phillips Head Screwdriver: Often needed for adjusting various screws on the binding.
- Flathead Screwdriver: May be required for certain adjustment mechanisms.
- Ski Boot: Your actual ski boot is essential for fitting and checking adjustments.
- DIN Chart (Optional but Recommended): While a technician will finalize DIN settings, understanding the chart helps grasp the factors involved.
- Measuring Tape (Optional): For checking boot sole length (BSL).
Step-by-Step Guide to Setting Up Marker Bindings
Setting up ski bindings is a precise task that should ideally be performed or verified by a certified ski technician. However, understanding the steps involved is beneficial.
1. Adjusting for Boot Sole Length (BSL)
Most modern Marker bindings feature an adjustable heel and/or toe piece to accommodate different boot sole lengths.
- Locate the Adjustment Mechanism: This is usually a lever or screw on the heel or toe piece.
- Insert Your Boot: Place your ski boot into the binding, ensuring it clicks securely into the toe piece first, then pressing down into the heel.
- Adjust for Snug Fit: Adjust the mechanism until the boot fits snugly without being forced. There should be no significant play when the boot is in. This step sets the initial length.
2. Checking Forward Pressure
This is a critical step to ensure your bindings will hold and release properly.
- With the boot in place, we can check the length and forward pressure. As highlighted in the provided reference, once your boot is clicked into the binding, it's essential to verify the forward pressure.
- Locate the Forward Pressure Indicator: Marker bindings typically have a visual indicator, often a screw head or a small tab, on the side or rear of the heel piece.
- Adjust to the Correct Range: Turn the adjustment screw (usually with a Phillips head screwdriver) until the indicator is within the specified range (e.g., flush, or between two lines). Correct forward pressure is vital; if it's too loose, the binding might pre-release; if too tight, it might not release when it should. This is important to make sure the bindings will hold and release properly.
3. Setting the DIN Release Value
The DIN (Deutsches Institut für Normung) setting determines the force required for the binding to release. This is calculated based on:
-
Skier's Weight: Heavier skiers generally require higher DIN settings.
-
Skier's Height: A factor in overall leverage.
-
Skier Type:
- Type I: Conservative, skis cautiously, prefers slower speeds.
- Type II: Average, skis moderately, comfortable at various speeds.
- Type III: Aggressive, skis fast, on varied terrain, prefers higher speeds.
-
Boot Sole Length (BSL): Used in the DIN chart calculation.
-
Age: Skiers over 50 often have their DIN reduced by one step due to bone density considerations.
-
Consult a DIN Chart: Use a standard DIN chart to determine the appropriate setting for your specific profile.
-
Adjust Toe and Heel DIN: Use a screwdriver to adjust the numbered dials on both the toe and heel pieces to your calculated DIN setting. Both the toe and heel must be set to the same DIN value.
4. Checking Toe Height (Anti-Friction Device - AFD)
The toe height adjustment ensures proper contact between your boot sole and the Anti-Friction Device (AFD), which allows the boot to slide laterally during a release.
- Check Clearance: With the boot in the binding, try to slide a credit card or a piece of paper between the boot sole and the AFD. It should slide with minimal resistance or a slight drag.
- Adjust if Necessary: Some Marker bindings allow for toe height adjustment. If yours does, use a screwdriver to adjust the mechanism until the correct clearance is achieved.
Post-Setup Checks and Professional Verification
After performing these adjustments, it's highly recommended to have a certified ski technician perform a binding function test. This test uses specialized equipment to verify that your bindings release consistently and accurately at your set DIN value, both laterally and vertically. This final step ensures your safety and the optimal performance of your Marker bindings.
Maintenance Tips for Your Bindings
- Keep Clean: Regularly clean any dirt, snow, or ice from your bindings.
- Store Properly: Store skis in a cool, dry place during the off-season.
- Annual Inspection: Have your bindings inspected and tested by a professional annually, even if they haven't been used heavily.
