STIHL M-Tronic™ : This product features M-Tronic™ (M) - a new generation of Intelligent Engine Management that eliminates the low and high speed carburetor adjustment screws, compensates for dirty air filter and changes in elevation and fuel quality for optimum engine power at all times.
Pre-Separation Air Filtration System: This time-saving technology boosts the efficiency of the engine’s filter system, doubling the time between air filter cleanings. 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.
STIHL Quickstop® Plus (Q) - an additional chain braking feature: STIHL offers an additional, manually-activated chain brake on some models. This system is designed to engage when the operator’s right hand completely releases the rear handle, stopping the chain within one second. Available on some models.
Toolless fuel and oil caps with retainers: Simply lift the lever and twist the caps to remove or tighten. There‘s no need to use a tool to tighten or loosen.
