Key Features of the TS 420:

• X2 Air Filtration System: The TS 420 inherits the revolutionary X2 Air Filtration System, a groundbreaking innovation in the cut-off machine industry. It allows air filters to last for up to a year, contingent on cutting conditions. The system introduces external air into a swirling motion, effectively eliminating 80% of dust particles. After this initial purification, the air passes through primary and secondary air filters before entering the engine. The X2 Air Filtration System is designed to be virtually maintenance-free, upholding an impressive 99.96% cleaning efficiency.
• Intellicarb Compensating Carburetor: The TS 420 incorporates the IntelliCarb™ Compensating Carburetor, which is engineered to autonomously adjust the air/fuel ratio when the air filter becomes obstructed or partially clogged. It ensures the engine maintains the correct RPM by utilizing clean-side air from the air filter to control the diaphragm and fuel flow. As the air filter collects dirt and less air becomes available for the carburetor, the IntelliCarb™ system adapts the fuel flow to counterbalance the decreased airflow. This sets it apart from conventional carburetors, which draw air from the "dirty" side of the air box.
• Water Connection: The inclusion of a water connection with a shut-off valve and quick connector enhances the machine's functionality and utility.
• Ergonomic Grip: The top-handle bar is ergonomically designed to deliver an optimally comfortable grip, regardless of the working position, thus maximizing user control and minimizing fatigue.
• Stihl Elastostart: The Stihl ElastoStart™ starter handle is a distinctive feature. It integrates a built-in shock absorber that significantly reduces the effort required to pull the starter cord. The ElastoStart™ starter grip substantially diminishes the sudden peak forces (compression) typically experienced during cranking. It smooths out the forces applied to the grip after the initial compression stroke.
• Anti-Vibration System: STIHL has devised an anti-vibration system for minimizing the vibrations generated by handheld outdoor power equipment. This system not only reduces operator fatigue but also ensures a more comfortable and manageable working experience.
• Bayonet-Style Filler Cap: Equipped with a bayonet-style filler cap complete with a retainer, this feature ensures ease of use, even while wearing gloves.
• Semi-Automatic Belt Tensioning: This feature offers consistent semi-automatic re-tensioning, effectively extending the service life of belts and shaft bearings.
• Reduced-Emission Engine Technology - Caring for Nature: The "Caring for Nature" seal from STIHL Inc. signifies its commitment to environmentally conscious powered products, known for producing zero or low exhaust emissions. STIHL Inc. defines "low exhaust emissions" as surpassing the cleanliness standards set by EPA and/or CARB exhaust emission regulations.
