ABSTRACT:
A saw chain for a power chain saw is provided and comprises drive links and side links that connect them, whereby alternatingly disposed on one and the other longitudinal side of drive links, in place of a side link, are a cutter link and a leading safety link. The cutter link has a cutter tooth and a leading depth limiter, whereby the safety link is provided with a projecting nose for support against the base of a cut. The nose extends in the direction toward the depth limiter. The safety link is provided with a side portion disposed in front of the nose. The side portion has an elevated contact surface, which, when the saw chain is curved in the reversing region, is disposed on the path of a top cutting edge of the cutter tooth, and when the saw chain is extended reaches at least nearly to the height of the depth limiter.
