content: Purchased saw to trim some medium sized trees. Unfortunately, when reading the literature which came with the saw, it states that using an extension cord more than 50 feet long is not recommended and that the saw could overheat with a longer extension cord. This makes it unuseable for anyone except those who have trees within 50 feet of an electrical outlet. You could use a gasoline generator, but this defeats the purpose of an electric saw and it is impractical. Nowhere on the website description does it caution you about this problem and this is a mistake for Amazon which I assume has many of these items returned for various reasons. Description should contain the extension cord limitation.
