Reduced-Emission Engine Technology - Caring for Nature
The STIHL Inc. “Caring for Nature” seal identifies its powered products that are more environmentally conscious, producing zero or low exhaust emissions. STIHL Inc. defines “low exhaust emissions” as being cleaner than EPA and/or CARB exhaust emission standards. 


Loop Handle (R)
Loop handle grass trimmers and brushcutters are ideal for trimming between bushes and shrubs and other areas where space is limited. 


Electronic Ignition Module
The electronic ignition provides reliable starting and because it is fully enclosed, it is protected from moisture and debris for longer service life. 


Multi-Function Control Handle
Having easy access to all of the controls on one comfortable handle makes it easy to complete tasks so the operator’s hand never has to leave the handle. 


Purge Pump Primer
By pressing the bulb, this small fuel pump delivers fuel to the carburetor, reducing the number of starting pulls needed after an extended break between uses. 


Anti-Vibration System
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.
