The STIHL Petrol TS 480i Petrol 30cm Cut-Off Saw is an innovative 3.9kW cut-off machine with electronically controlled fuel injection. At the heart of the TS 420 is a 2-stroke engine with stratified charge. A fuel-free layer of air is created between the burned charge in the combustion chamber and the fresh charge in the crankcase, reducing the amount of fuel lost during the charge cycle. This results in more power with a lower weight, up to 20 lower fuel consumption than regular 2-stroke engines and significantly reduced exhaust emissions. The electronically controlled fuel injection ensures perfect running properties every time and reduces fuel consumption in comparison with tools without injection technology. The electronic water control system can be operated via simple buttons while the engine is running. The water then switches on and off during cutting automatically, depending on engine speed. The water volume can be regulated by simply pressing the plus minus buttons, ensuring optimum dust suppression at the touch of a button. Intense vibration at the handles of power tools can lead to long-term effects on blood vessels in the hands and arms. STIHL has therefore developed an effective anti-vibration system whereby the oscillations from the machines engine are dampened which significantly reduces vibrations at the handles. STIHL long-life air filtration systems with pre-separation achieve perceptibly longer filter life compared with conventional filter systems. Air drawn in is swirled. The larger, heavier particles are ejected. The pre-cleaned air is routed to the air filter via the pre-separator duct. The cutting wheel guard made from die-cast magnesium is particularly light. The guard and water attachment feature a particularly ergonomic design. The modern, ergonomic design allows each user to work with an optimal grip position. The loop handle facilitates excellent cutting comfort in any working position.
