The TS 420 is so popular, it could possibly be called “the standard” to which other cut-off machines are compared. Users like it because it is compact, lightweight, reliable and proves itself day in and day out, all day long. The TS 420 features all the high-performance features of the TS 410 – including an X2 air filtration system for a clean and smooth-running engine and virtually maintenance-free filters. With the added benefit of a 14” cutting wheel, it will handle cuts up to 4.9 inches in depth. This cut-off machine backs up its larger cutting capacity with a ton of usability features.
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.
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.
