Abstract:
The application relates to a chainsaw system and chain guard for a chainsaw with interchangeable cutting attachments of different lengths. The cutting attachments have cutting chains, and the chain guard includes an insertion opening for inserting a cutting attachment, at least two side walls for covering lateral surfaces of the cutting attachment, a front end opposite the insertion opening, a first latching depression formed in at least one side wall, and a second latching depression formed in at least one side wall at a distance closer toward the insertion opening with respect to the first latching depression. The first latching depression and the second latching depression each include an arcuate latching surface for latching in a form-fitting manner with a cutting chain of the cutting attachment, such that the latching is active in the direction of a longitudinal axis of the chain guard.
