Stihl MS291 Chain Saw 18" Bar

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.

The STIHL anti-vibration system helps reduce operator fatigue and provides a more comfortable working experience.

Air drawn into the engine is first separated via centrifugal force, ejecting the heavier dirt particles before being routed to the air filter. This pre-separation means less dirt to be captured by the air filter, resulting in less frequent cleaning and maintenance.

The side-access chain tensioner makes it much more convenient for the user to adjust the saw chain with a bar wrench as opposed to the typical location of the guide bar adjustment screw.
