Abstract
The invention relates to a chipper chain () for a motor-driven chain saw () as well as a chain saw having such a chipper chain (). The chipper chain () includes drive links (), connecting links (), and cutting links (). The drive links () each have a drive projection (). The cutting links () each have an upper cutting blade () and a depth limiter () which leads the upper cutting blade (). The chipper chain () has a maximum width (A) which is defined by the upper cutting blades (), a maximum height (C) which is measured perpendicularly to its longitudinal axis and extends from the drive projection () to the upper cutting blade (), and an average divide (T) predetermined by the average distance of adjacent pivot pins (). The product of the maximum width (A), the maximum height (C), and the average divide (T) is ≤450 mm. The driving power of the motor-driven chain saw () is ≤1.0 kW.
