The Power Mac 6 loggers chain saw at 2 cu in. and 6.5 lb cuts 2.8 sq ft of wood per minute. It was designed to satisfy both the casual user and the professional market, where its light weight and ease of handling make it quite attractive. The weight and configuration of the saw are analyzed to show developments which permit more productive and safer modes of operation. Component design and functioning are reviewed principally in their relation to the whole package and its performance.
