1. A self-powered chainsaw, comprising;
a housing, an electric power source, an endless cutting chain having a plurality of cutting elements, an electric motor arranged to drive the chain relative to the housing using power from the electric power source, a sharpening element which is configured to be driven relative to the cutting elements and the housing, and a controller configured to control how the endless cutting chain is driven, the controller having a normal mode in which the endless cutting chain is continuously driven so that it is usable for cutting, and a step mode in which the chain is driven only in discrete steps, and wherein the sharpening element uses the electric power source and is driven at least a portion of the time when the controller is operating in the step mode, wherein in the step mode, the electric motor drives the endless cutting chain in steps, wherein a size of each step is determined by the spacing of the cutting elements of the chain. |
