Questions people ask

What size chain does an Echo CS2511T take?

The Echo CS2511T with a 12" bar takes 3/8" LP pitch, .043" gauge chain with 45 drive links (Oregon R45).

What bar fits an Echo CS2511T?

A bar with the A041 mount, in one of these lengths: 12".

Can I use a chain with the same length but different pitch?

No. Pitch and gauge have to match the bar and sprocket, and the drive link count has to match the bar. A chain that is off on any of the three will not fit or run safely.
