A manually guided implement having a tool and a brake mechanism for the tool. The brake mechanism includes a brake band that is looped about a brake drum. The brake band and the brake drum form abrasion partners that cooperate with one another during a braking process. At least one of the abrasion partners has a coating. The coating is provided with diamond particles that are embedded in a matrix that contains nickel. The coating is effected in a nickel bath in which the diamond particles are dispersed.

Manually guided implement and method of producing a brake mechanism of a manually guided implement

An implement having a drive motor and a tool is provided. A drive shaft is mounted in a guide tube and interconnects the drive motor and tool for rotatingly driving the tool. The drive shaft includes a main member in the form of a hollow shaft having ends on which are disposed respective extensions that form a coupling connection for a positive engagement with coupling components of the drive motor and of the tool.

Motor driven implement

The invention relates to a saw chain for a motor-driven chain saw equipped with a guide bar and a drive motor for imparting a force to the saw chain for moving the latter around the guide bar in a predetermined running direction. The chain saw is further equipped with a device for supplying lubricating oil to the saw chain during the movement thereof. The saw chain includes a plurality of cutting links, a plurality of driving links and a plurality of side links all pivotally interconnected by rivets. Abrasive small particles become entrained in the lubricating oil which can lead to premature wear at the pivot locations. The saw chain of the invention includes a hold-back element in front of a rivet to hold back such particles and yet not affect the flow of lubricating oil to the pivot connection.
