Dynastar PX12 binding issue

post #1 of 10
Thread Starter 

I have year old PX12s mounted to Sultan 85s.  For both bindings, when I go to step in the binding does not fully catch but instead catches partially so that I can't pull my boot out without manually releasing the binding but at the same time it's not fully clasped (i.e the heel piece is not raised all the way vertically).  I have always been able to eventually get it fully clasped but there doesn't appear to be any rhyme or reason to it.  Sometimes shifting my weight will work.  Sometimes lifting my ski and putting it back down will work.  I'm on my way to the shop now to get 'em tuned and have a tech look at them but I'm hoping somebody here might have encountered this before in case the tech hasn't. 

 

The fact that it happens to both bindings and every time I step into my bindings really has me scratching my head.

 

 

Any thoughts would be appreciated.

Sounds like the heel is not all the way open\cocked. But in any case have the tech check the forward pressure window behind the heel.

I have the same bindings and occasionally the same issue.  I usually, just stomp down harder and it will pop into place.  At first I thought it was snow clogged in there, but it will happen when clean too.

And I thought it had to with the fact that the PX12's slide in and cock so to speak with forward motion of foot, but yes, it is sometimes a pain, with that half-way semi-cock of the lock, and I find sliding forward on the ski engages the lock, but on a steep slope with a lot of snow, could be painful to get skis on...no doubt about it

When you step in to the binding and push down and get the mushy, half click in can you reach back and pull up on the big heel lever to get it to engage/lock fully?

 

Believe some have pointed out before that approach could be useful getting skis back on in powder. Maybe just use it as the method for clicking in all the time?

I've had this happen occasionally.  I found the best way to avoid it is to makes sure the heel piece is pushed all the way down before stepping in.  I've never had a problem when I take the time to do that.

if the forward pressure adjustment is set to the light side, and/or/ the bottom edge of the boot heels are worn, the boot can't get enough downward pressure on the TAB on which you step. Binding engages partially ...

not enough forward pressure, heel slides back against light forward pressure, before it overcomes the release spring setting and fully locks - often the boot gets captured by the heel tab...

worn heels, same outcome...

This has always been more of an issue with Looks/similar heels.

 

Check your boots for wear on the heel ends on which you walk, not the upper ledge where the Binding engages. Many boots have the option to replace the heel plate for that very reason.

here's a pic of a badly worn heel...

it doesn;t have to be this bad to cause your issue...

If you're not real light and/or ski the bindings at lower DIN settings (below 6 on toepiece) then there is the possibility that a slightly high forward pressure setting will allow you to close the binding properly.

Forward pressure is not a critical adjustment except that it should not be tooo light or tooo strong (depending on the binding release settings) - other there's a wide usable range for most modern binding systems.

If you're not sure - take to shop, along with boots, so nosepicker can chek it out for you...

jc-ski, you were right, a helping hand got the heel-locks to click into place as you advised. thanks

I happened on that really by accident one night setting up a pair of Rossi B3's with Axial demo bindings for my girlfriend to use. Set the bindings to her smaller boot size, but had the skis on the floor, and could not push down on the the boot hard enough to get it to click into the heel piece. Finally just grabbed that big old heel lever and pulled up as I pushed down on the boot, and, bingo, in it went, clean and snug!

 

Anyway, glad it worked for you!   ;-)
