Drive-link counts come from STIHL's saw-chain selection chart and depend on the bar mount as well as length. Pick the chain link that matches the gauge stamped on your bar. Bar searches include mount 3003 / D025; still confirm the mount stamp, pitch, gauge and drive-link count on your installed bar before ordering.

Drive-link counts: STIHL 2025 US catalog, saw chain selection, pp. 166-167; Oregon chain fit guide, STIHL section. Checked Nov 2026. How we check fitment

Files, oil & sharpening

Round file 7/32" (5.5 mm) for Oregon; STIHL lists 13/64" (5.2 mm) → Bar & chain oil → 2-in-1 sharpener →

Suggested match: Oregon 72 (.050″) / 73 (.058″) / 75 (.063″) series, e.g. 72/75 EXL. Match the gauge and confirm the drive-link count for your exact bar before ordering. These are equivalent aftermarket (Oregon) chains, not genuine STIHL chain — STIHL sells its own chain through its dealer network, and we're not affiliated with STIHL. New to fitment?
