Drive-link counts from STIHL's saw-chain catalog. The chain is set by pitch + length (confirm the count stamped on your bar); the guide bar also depends on your saw's mount, so verify fitment before ordering.
Files, oil & sharpening
Suggested match: Oregon 72/73/75 EXL. Confirm the drive-link count for your exact bar length 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 pitch & cutter types? See the chain & cutter guide.
