How to confirm the fit

Read your bar. The pitch and gauge are stamped on the guide bar near the saw body — e.g. 3/8" LP .050".
Count drive links. Lay the old chain flat and count the teeth that ride inside the bar groove. This number must match exactly; length in inches is not enough.
Match all three. Pitch, gauge and drive-link count all have to agree with a row in the table above. Two of three is not a fit.

FAQ

What size chain does a Makita DCS5121 take?

The Makita DCS5121 runs a .325" pitch, .050" / .058" gauge chain. Available bar lengths: 13", 15", 16", 17", 18", 20", 23", 24". Match the drive-link count to your bar (see the table above).

How do I know which gauge my DCS5121 chain is?

Check the number stamped on your guide bar near the tail, or measure the drive-link thickness with calipers. Common gauges for the DCS5121 are .050" / .058", .058", .050".

Can I put a longer bar on my Makita DCS5121?

Oregon lists 13", 15", 16", 17", 18", 20", 23", 24" bars for the DCS5121. Stay within this range — a longer bar than the engine is rated for cuts slowly and accelerates wear.
