Not sure which bar you have? Check the numbers stamped on the bar tail: pitch, gauge and drive-link count. The same "16-inch" bar can take a different chain depending on the bar mount, so the drive-link count is what matters.

Chain types for the MS 250

  • PICCO Micro 3 (63PM): 3/8" P pitch, .050" gauge, low-kickback semi-chisel; sharpen with a 5/32" (4.0 mm) round file.
  • PICCO Super 3 (63PS): 3/8" P pitch, .050" gauge, full chisel, faster cutting; sharpen with a 5/32" (4.0 mm) round file.
  • Rapid Micro 3 (26RM): .325" pitch, .063" gauge, semi-chisel, holds an edge in dirty wood; sharpen with a 3/16" (4.8 mm) round file.

Which chain should I buy?

For general firewood and storm cleanup, the semi-chisel loops (RM / PM) are the safest choice: they forgive dirt and are quick to touch up with a file. If you cut clean, seasoned wood and want maximum speed, choose the full-chisel loops (RS / PS). Buying two loops and rotating them is the easiest way to keep the saw cutting while one is being sharpened.

MS 250 chain FAQ

What size chain does a STIHL MS 250 take?

The STIHL MS 250 runs .325" or 3/8" P pitch chain. The loop depends on your bar length and gauge: 14" (3/8" P bar) bar = 63PM50/63PS50; 16" (3/8" P bar) bar = 63PM55/63PS55; 16" (.325" bar) bar = 26RM62/26RS62; 18" (.325" bar) bar = 26RM68/26RS68. Match the drive-link count stamped on your bar.

How do I count drive links?

Lay the chain flat and count the tangs on the inside of the loop, the parts that ride in the bar groove. That number must match exactly; one off and the chain will not tension correctly.

Semi-chisel or full chisel?

Full chisel (RS/PS) cuts fastest in clean wood. Semi-chisel (RM/PM) stays sharp longer in dirty, frozen or storm-damaged wood and is easier to sharpen.
