Never heard of that brand, but I can tell you the big secret to knitting machines is to make sure they are really, really clean--no dirt or dust to jam the action of the needles.
Most modern machines are "hem-weighted" and use a system of weights attached to the bottom of the knitting. It takes a whole lot of tension on the knit piece to make such machines work and you must move the weights up every so often to keep the tension strong and even.
There are older machines that work with a sort of "sinker" action whose name I have forgotten. They have movable plates between the needles that put tension on the knitting and which work extremely well so long as they are well lubricated and move freely.
