Stihl FS 45

2-Stroke · Also known as: FS 45 C

The Stihl FS 45 is a 27.2cc <!-- verify: stihlusa.com --> 2-stroke curved-shaft trimmer and the most popular model in Stihl's entry-level FS range. Commonly sold in homeowner bundles, it is well-suited for regular lawn edging and light brush maintenance. The FS 45 runs a Zama carburetor and is mechanically similar to the FS 38 and FS 40. The bump-feed head accepts .080" line. An adjustable loop handle accommodates operators of varying height. Primer bulb, fuel lines, and air filter are routine maintenance items. Draining the fuel system before winter storage prevents stale-fuel no-start conditions.
