Tensionhead "crushing" the string

I string on a Stringway ML100, and have some problems when pulling tension on "softer" strings. It works fine on polyester strings, but it almost crushes multifilament or natural gut.
Tried with a string up a racquet with Klip legend the other day, and it snappped after just a few mains:(
Please help me out, if you have a solution to this problem:)

I have an ML 100 also. Are you letting the dropweight down slowly/gradually? I am not sure if it would do what you're experiencing, if you just let go of it and let it bounce. But I suppose it's possible, especially if you were set for a high tension.

If you are letting the dropweight down very slowly, can you post a picture(s) of how you're string is going through the tension gripper? Maybe someone with that machine can see from a picture, what the trouble is. Better yet, if you have the capability, post a short video on YouTube of the whole process of putting the string in the tensioner, and then pulling tension on one string, and add the link in a reply to this thread. Then it might be obvious what's causing the problem.

Try wrapping around the center bump and back -- such as to clamp the string on both left and right side of the tensioning jaws. This will half the pressure. I guess by the same token you can make 2 circles, thus clamping 4 strings at the same time. The pressure will reduce by 4.

How are you sure it is because of the tensioning jaws? Can the string get crushed by the clamps?

Hey guys, and thanks for your all your tips.
I will try them out the next time I`m stringing with multi or natural gut.
There isn`t any screw to loosen the presure, so maybe I`m just dropping the bar to quick!
I`m shore it`s not the clamps causing the damage on the strings, `cause I watched the string carefully last night when stringing the racquet with Xcel multi.
It`s right where the string goes under the tensionjaws, it turned white, like it was crushed inside.
But I will try to lower the bar more slowly the next time, and wrap it around the tensionjaws to divide the pressure on the string.
All in all I`m very pleased with this stringer, so I`m hoping this will solve the problem.

You may discover that Xcel will get crushed no matter what.
If you clamp it well in the clamps, you will see it turning white.
If you do not clamp it well, it will slip.
I have not found a way to avoid one or another.
I have had that Xcel on my racquet for over 2 months now -- it does not seem to have any adverse effect on it. It appears, some strings are just "touchy".
