Features
- Made in America

STIHL has a system for minimizing the vibration levels of handheld outdoor power equipment. The STIHL anti-vibration system helps reduce operator fatigue and provides a more comfortable working experience. - IntelliCarb™ Compensating Carburetor
The IntelliCarb™ Compensating Carburetor measures the air pressure on the air filter’s clean side and adjusts the carburetor’s metering diaphragm. This keeps the RPM consistent, even when the air filter begins to clog. - Simplified Starting Procedure
To start, pump the fuel primer, set the choke, and pull the starter cord. The built-in stop switch lets the user turn off the engine with a simple button press. The throttle lock automatically returns to the “start” setting when the engine is off. Your power tool will be ready to start when you’re prepared to return to work. – See it in action! - Reduced-Emission Engine Technology – Caring for Nature
