Abstract
A chainsaw includes a housing, a guide bar, projecting from the housing, and one or more handles. The guide bar has a main direction of extension defined by its center-line. The housing comprises an outer shell made of plastic, which has at least a first outer groove filled with a contrasting plastic material, wherein the groove at least partly extends straight in a transverse direction that deviates less than 3 degrees from a direction perpendicular to the main direction of extension of the guide bar. This provides an indication that facilitates precise and safe felling of trees.
