Chain saws come in different classes and are designed according to purpose. Chain saws designed for light work, such as carpentry, will have a lower horsepower and a smaller engine. Chain saws used to cut down trees or clear debris typically have larger engines and more horsepower. Echo makes several chain saws that have a range of horsepower and specifications.
Although Echo makes chain saws to suit most needs, the Echo CS-600P is one that can handle light work and industrial jobs. The saw features a 59.8 CC engine that gets up to 4 horsepower while cutting. It also features a tool-free air-filter replacement system, a 20-inch bar and a decompression valve. According to Popular Mechanics, the saw's engine "operates with a broad torque curve, and that power comes shining through in the tough cuts."

While the CS-600P is more of an all-purpose saw, the CS-310 is built for light use and simple lawn care activities. This chain saw features a 30.5 CC engine that gets up to 1.8 horsepower. It has a digital i30 starting system. This saw's set bar is 14 inches long. While small compared to the CS-600P, this chain saw is designed for trimming hedges, branches and light building jobs.
At the other end of the spectrum from the CS-310 is the CS-8000. This saw features an 80.7 CC engine with 6.29 horsepower. It features an automatic oiling system with a manual override, bar lengths that range from 24 inches to 36 inches and a butterfly valve diaphragm without a purge pump. This saw is designed for cutting lumber and industrial work.
Although not quite as powerful as the CS-8000, the CS-530 has a 50.1 CC, 3.2 horsepower engine that is designed for light industrial or home jobs. This saw supports an 18-inch or 20-inch bar and features an automatic adjustable oil distribution system. Like the CS-8000, the CS-530 has a butterfly valve carburetor diaphragm without a purge pump.
Designed specifically for home use, the CS-450 has a 45 CC engine that gets up to 2.3 horsepower. This chain saw supports 16-, 18- and 20-inch bars and features a clutch-driven automatic oiling system. The CS-450 also features a butterfly valve carburetor diaphragm with a purge pump.
