Abstract
A battery-powered chain saw is provided which chain saw comprises a housing (10) extending in a longitudinal direction (X) between a front end (12) and a rear end (11), a rear handle (20) fixedly connected to or integral with the housing (10) and extending in the longitudinal direction (X), a front handle (30) fixedly connected to the housing (10) and an electric motor (40) arranged to drive a cutting element of the chain saw, the electric motor having a motor rotation axis (A1). The chain saw has a longitudinal rotation axis (X1). It is characterized in that a point (60) in which a center axis (A2) of an upper portion (31) of the front handle (30) intersects a vertical plane (P) comprising the longitudinal rotation axis (X1) of the chain saw, is positioned rearwardly of a point (70) in which the motor rotation axis (A1) intersects said vertical plane (P).
