Fitting the saw chain on the Echo DCS-2500T with the cutters pointing in the arrow's direction; the sprocket cover's chain tension adjuster (G) fits into the guide-bar hole. Figure from the Echo DCS-2500T operator's manual, p. 31 (PDF).

Doesn't fit

Echo CS-2511T / CS-271T fitted with the .043 12A4CD3745C (Micro-Lite) bar — Same saw, different factory 12" bar. That bar takes .043 gauge 90PX45CQ, not .050. (source)

Echo CS-2511T / CS-2511P / CS-303T with 14" bar — Same saws also ship or run with a 14" bar, which needs 52 DL (91PXL52CQ / 91PX52CQ), not 45. (source)

Echo CS-355T / CS-361P with 16" bar — Similar top/rear-handle Echo saws. At 16" they use 91PXL57CQ (57 DL). (source)

What this is

Two replacement chains in the size of Echo’s 12” 91PXL45CQ and 91PX45CQ: 3/8” low-profile pitch, .050” gauge, 45 drive links. Echo’s manuals list this size for the battery DCS-2500T and for gas top-handle and rear-handle saws running the 12” .050” bar: the CS-2511T, CS-2511P, CS-271T, CS-303T, CS-301, CS-330T and CS-360T.

Check your bar’s gauge

Echo sells the CS-2511T and CS-271T with two different 12” bars. The standard bar (12A0CD3745C) is .050” and takes this chain. The Micro-Lite bar (12A4CD3745C) is .043” and takes 90PX45CQ, a thinner chain of the same length. The bar part number and gauge are stamped on the bar tail; for the .043” bar see our 12” .043” chain.

Several of these saws also run a 14” bar, which needs a 52-link chain.

Fitting it

The DCS-2500T and CS-2511T have a side-access chain tensioner. Echo’s CS-2511T manual requires a chain designated low-kickback meeting ANSI B175.1 or CSA Z62.1.3, and Echo warns to use only its listed bar and chain combinations with matching gauges.

Frequently asked questions

My CS-2511T has a .043 bar. Will this fit?

No. Echo sells the CS-2511T and CS-271T with either a .050" 12" bar (12A0CD3745C) or a .043" Micro-Lite bar (12A4CD3745C), which takes 90PX45CQ. For the .043" bar see our [12" .043" chain](/product/3pc-12-inch-chainsaw-chains-b0btbswwtl/).

Is it 3/8" or 3/8" low-profile?

Low-profile. Echo's 91PX and 91PXL chains are 3/8" low-profile; standard 3/8" chain won't fit these saws. The Amazon listing just says 3/8".

What file size do I sharpen it with?

Echo's figures differ: its 91PXL page and the DCS-2500T manual give 5/32" (4.0 mm), while the CS-2511T manual says 3/16". Match the file to the cutter you have.
