• STIHL Easy2Start™ (E) - The STIHL Easy2Start™ system makes starting STIHL outdoor power tools almost effortless, eliminating the need for a strong pull of the starting cord. This advanced starting system is designed to make starting STIHL products easier. The specific system may vary by model, but in each case, a quick pull overcomes the engine’s compression to minimize the strength and effort required to start. Available on selected products.
• Diagnostic Socket - The convenient diagnostic socket makes it easy for a local STIHL Dealer to plug in the chainsaw and access information about operating time, diagnostic support, and more.
• IntelliCarb™ Compensating Carburetor - The IntelliCarb™ Compensating Carburetor is designed to automatically adjust the air/fuel ratio when the air filter becomes restricted or partially clogged and maintains the engine’s correct RPM. IntelliCarb™ uses air from the clean side of the air filter to control the diaphragm and flow of fuel. As the air filter becomes dirty and less air is available for the carburetor, the IntelliCarb™ system adjusts the fuel flow to compensate for the decrease in air flow. This is in contrast to typical carburetors that utilize this air from the “dirty” side of the air box.

• Easy-Access Air Filter Cover - The provided easy-access makes it almost effortless to remove the cover for fast filter cleaning or replacement.
• Anti-Vibration System - STIHL has developed 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.
• Spark Arrester Muffler - Large baffles reduce noise level and contain a screen designed to reduce the emission of sparks.
• Side-Access Chain Tensioner - 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.
• Throttle Trigger Lockout - This safety feature must be depressed before the trigger can be activated.
• High-Tech Polymer Housings - Housings are lightweight, withstand greater impact, and are corrosion-resistant.
