chain break
If there inst enough room between the handle and the chain break causing it to engage prematurely, then heat and bend it away into the correct position. or replace the plastic one with a home made metal one. I have seen both, and they both work properly. Just because it didnt come from factory, or because I didnt pay some over inflated price, because some schmuck that sits behind a desk creating new laws, to have products he has no Idea how to use, cross his desk for his god like thumbs up and seal of approval. dosnt mean it dosnt work. Remember chain breaks and many other "safety" items were created and Improved on by some guy F ing around in his garage, because he was tired of working with poorly crafted crap in the first place.
