PDF and factory spec weights mean nothing. It's the main reason we started a chainsaw weight archive back on another site - manufacturers flat out lie or are incompetent when stating weights. Oftentimes when the weight is cited, it is without the clutch cover, which most would claim makes it very difficult to use a saw unless you want to run it hotsaw style. If you want to discuss weight with any real basis, you have to show the thing on a scale or quote the chainsaw weight archive. Otherwise, it's just speculation.
