Abstract
An arrangement for lubricating saw chains of power saws. The chains include chip removing members, cutting tooth members, connecting links, and other chain members joined by rivet connections. The extensions of the chip removing members run in a guide bar provided with an oil supply. The chip removing members are provided on at least one of their side surfaces with at least one oil guide in the form of a groove in the side surface, which guide extends counter to the running direction of the saw chain and at an incline upwardly toward the rivet connections. The oil guide merges into an oil channel which with at least one of its ends is located in the vicinity or close range of a rivet hole.
