As of January 2011, the 446s chainsaw features a displacement of 2.7 cubic inches. The 44.6 cc engine creates 3.1 horsepower. The fuel tank has a capacity of 18.2 ounces and the oil tank has a capacity of 9.1 fluid ounces. The fuel mixture requires a 50:1 ratio of regular gasoline to mixing oil.
The 446s weighs 9.9 lbs. without any fluids. The bar length is 16 to 18 inches long.
No tools are required for air filter removal. A spring-assisted starting system allows the chainsaw an easier startup. An aluminum handlebar cuts down overall weight. An anti-vibration system reduces user stress during operation. The 446s also uses a dual-post, inertia-activated chain brake for increased safety.
