Abstract
A motor chain saw has a housing, a motor arranged in the housing, a drive pinion driven by the motor, and a guide bar connected to the housing. A saw chain is driven in circulation about the guide bar by the drive pinion. A lateral panel is arranged between the housing and an attachment section of the guide bar. The guide bar and the lateral panel each have a distance relative to the drive pinion upstream and downstream of the drive pinion when viewed in a circulating direction of the saw chain. The lateral panel has a first guide that guides the saw chain at a level of rivets of the saw chain, wherein the first guide extends approximately parallel to the plane of the guide bar.

A motor chain saw comprising:
- a housing;
- a motor arranged in the housing;
- a drive pinion driven by the motor;
- a guide bar connected to the housing;
- a saw chain extending about the guide bar and driven in circulation about the guide bar by the drive pinion;
- a lateral panel arranged between the housing and an attachment section of the guide bar;
- wherein the lateral panel has a first guide that guides the saw chain and is arranged adjacent to rivets of the saw chain, wherein the first guide extends approximately parallel to the plane of the guide bar;
- wherein the lateral panel has a slanted section neighboring a cutter of the saw chain, wherein the slanted section is slanted away from the cutter;
- wherein the lateral panel has an upper longitudinal section provided with a bulge, wherein the first guide and the slanted section are formed on the bulge;
- wherein the upper longitudinal section has a base surface that is slanted relative to a base plate of the lateral panel in a direction away from the guide bar;
- wherein the base surface of the upper longitudinal section rests against a housing wall of the housing and wherein the bulge has a leading end and a trailing end in the circulating direction, wherein the leading and trailing ends pass into the base surface of the upper longitudinal section.
