No experience of chainsaws before, but after getting fed up of hand sawing logs I bought one! It's only a fairly cheap McCullough petrol model. The instruction manual isn't the best and in the interest of safety I just want to check out how hard (or not) the chain brake should be to operate. It takes a fair effort to put it on (and take off) to the point where I feel like it's going to snap everytime I do it. Is this normal, because it is a cheapo model, or is something likely setup wrong? It does actually do what it's supposed to do. Cheers, Matt
