If you are cutting hedge, or other harder wood, if your chainsaw chain starts to smoke, or turn blue, STOP! Try a different chain, or bring it in to us for sharpening. "Burning" a chain is usually a result of not having the teeth sharpened right. We place both a top and center bevel on the teeth. This gives you two cutting surfaces on the same tooth, "cutting" your saw time significantly. Never A Dull Moment!
