ECHO Introduces New Chain Saws with Tool-less Chain Tensioning The latest additions to ECHOs chain saw line-up are the CS-370F and CS-400F. Both of these saws are based on the popular CS-370 and CS-400 but feature the new FasTension Tool-less Chain Tensioning System. The FasTension System makes quick and easy chain tension adjustments or bar and chain replacements without a wrench or tightening tool. A rotating lever takes the place of locking nuts and a tensioning wheel replaces an adjustment screw. Adjustments can be made anywhere in four simple steps. The CS-370F is equipped with a 16 bar and chain and the CS-400F comes with an 18 bar and chain. Other product features include a tool-less access, automotive-style air filter; a dual-post chain brake; an i-30starting system for reduced-effort starting; and an automatic, adjustable oiler. An after-market accessory is also available to retro-fit the FasTension Tool-less Chain Tensioning System on any CS-370 or CS-400. As with all ECHO chain saws, the CS-370F and CS-400F are covered by a one-year commercial warranty and five-year consumer warranty.
