Files, oil & sharpening
Suggested match: Oregon 27/59-series. 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 fitment? See the bar-mount identification guide and chain & cutter guide.

Screw figures are turns open from lightly seated. These are the figures every model in this family shares; an individual model page may be more specific. Matched on the base model number rather than this exact variant, so treat it as a starting point. Set the final mixture by ear and tachometer against the machine in front of you — running a two-stroke lean to hit a published number is how pistons get scored.
