Files, oil & sharpening
Suggested match: Oregon 95-series (95VPX) / 21–22 LPX. 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?

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.
