Mounting Marker M12 Bindings

I just bought a used pair of Volkl Motion skis. They have a rail system that is part of the ski. The bindings are Marker M12. Yes, I know these are old skis & bindings, but I am old also.
My questions is, how do I dismount the interface plate used by the bindings, so I can adjust the binding to fit my big feet (boot)?

Hi Bill, welcome to J2ski.
Errm, why are you wild? -)
I have a pair of Volkl Vertigos, long and fast, cannot remember the binding system.(They are in a cellar in Austria.)
For your bindings have a look at: http://www.youtube.com/watch?v=BTqlv10_TqM

On the subject of bindings, I have always rented skis, but have for a few years been using my own boots, and am generally quite happy with the arrangement. But the thought occurs to me, that I have always placed total trust in the renter adjusting my bindings for me, so far without problem, but I suppose I really ought to able to judge and check what the shop has done. Is there anywhere either on this forum or somewhere else where I could find a beginner's guide to setting your own bindings etc ?

Thanks for any info.

All trained professional ski mechanics will tell you they use, what is called, a DIN number. This number uses many factors such as height, weight & ability to set the tension on you bindings. If the shops where you rent use this setting system, you should be fairly safe.

However, I prefer to have my bindings set quite loose, especially the toe. My thinking is that I need to roll my ankle over to make a proper turn. So if I twist my ankle, I will probably pop out of the binding. That will remind me to roll my ankles instead.

Billip, everyone should know their own DIN number, mine is 7.0.
If you google DIN number followed by the names of various binding manufacturers, you will be able to access DIN charts. If you complete 2 or 3 of these, you should find a close correlation, say 5.5 and 6.0.
That way, you can double check the technician's DIN value. The only time an error is likely is if any of the parameters have been incorrectly entered. It can happen.

WildBill, this a mistake. It is one that I made a few years back, when, because my knees were having a particularly bad season, I backed off from DIN 7.00 to DIN 4.5.
One day, I went off piste, and walked out of a ski. Being soft snow, the ski brake didn't have any effect. I followed the surface marks for 200m down a steep face, and found just 6" of the tail sticking out from the snow.
There is some risk if you have your binding set at your standard DIN setting ~ and that is if you have a slow, twisting fall, or, like my frau, you have a tendency to fall over in lift queues!

Lots of information on binding installation, maintenance and adjustment can be found in the manufacture's manuals, this one is from Salomon http://www.yumpu.com/en/document/view/10901972/2012-2013-shop-practice-manual-salomon-certification

Useful things to know include; your skier type, your DIN setting based on skier type, age, height, weight, and boot sole length and how to check that the binding's forward pressure has been set correctly. The correct forward pressure is critical; if it is not set correctly the bindings won't function properly. The adjustment and indicator mechanisms vary from brand to brand, but they are always located on the heel piece.



It's also a good idea to check the condition of the AFD and the boot soles; if the soles are warped or excessively worn the bindings won't function properly.
