Echo SRM-210

2-Stroke

The Echo SRM-210 is a 21.2cc <!-- verify: echo-usa.com --> 2-stroke straight-shaft trimmer and the entry point to Echo's SRM commercial trimmer line. Despite its consumer-friendly price, the SRM series is built to professional standards — the same commercial-grade construction as the SRM-225 but with lower displacement for lighter residential and occasional commercial use. It runs a Zama carburetor and accepts .080" or .095" bump-feed trimmer line. Common maintenance items are the spark plug (Champion CJ8Y), air filter, fuel filter, and primer bulb. Echo's 5-year consumer warranty applies.
