Adjust toe jaw height first, with same technique as used with Fritschi or Marker.

Adjusting DIN should be obvious. Lateral release is the front screw on the heel-jaw unit (the “slide” that moves along the dual rails of the frame-plate, and holds your boot heel down). Lateral release indicator is on the underside of the “slide.”

Vertical release is the top screw on the “slide.”

Sole length adjustment is accomplished by rotating the screw at the rear of the binding frame/plate, which moves the heel-jaw unit (the “slide”) along the two rails. Adjust length so your boot heel drops in without jamming, but can still step down and cause the jaw to close on the boot heel.

After doing above, forward pressure (exact adjustment for sole length) is the only tricky part.

According to the manual, “the forward pressure is correct when the forward pressure indicator aligns with the rear wall of the slide.”

Look at the rear wall of the “slide” and you’ll see a small metal collar sleeve that the length adjustment screw passes through. This is the “forward pressure indicator.” Rotate the length adjustment screw till the “forward pressure indicator” is flush with the rear wall of the slide. Recheck that your boot exits and enters the heel unit without binding.

After forward pressure is adjusted, recheck lateral release value by looking at indicator with boot in binding. Adjust if necessary.

Remember that DIN/ISO standard allows a variation of indicated release value of plus or minus 15% !!! That means one full line up or down from what’s indicated on the binding by the numbers. In other words, take care with how high you initially set the release value (true for any binding).

Know that the Pure lateral release is accomplished by the “slide” moving back as the toe of the boot rotates against the fixed and immobile toe jaws. I’ve never been impressed by this system, as the slightest additional friction in the toe area will dramatically increase the lateral release value, as will any slight change in the forward pressure (due to change in adjustment, ice on boot, whatever). Keep your boots clean, and perhaps spray the toe jaw with some silicon once in a while.

Get after it. If you fool around the above should be very obvious.

I’m in the same boat as Ian Hunt above, I bought a pair for skis second hand with these bindings, and am looking for a procedure to adjust the sole length and DIN settings. Do you have a copy of the manual, or can you provide the nutshell version?

Thanks!

I got into shortening the Pures because they work best for lighter/smaller people anyway, so they’re the perfect binding for kids, tiny women, tiny guys, mice, folks like that (grin).
