TS 420

Standard features

• STIHL 2-MIX engine with stratified charge system

  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.

• Pre-separation air filtration system

  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.

• Anti-vibration system

  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 machine's engine are dampened which significantly reduces vibrations at the handles.

• Manual fuel pump (Purger)

  A small fuel pump delivers fuel to the carburettor at the touch of a button. This reduces the number of starting strokes required following extended breaks in operations.

• Semi automatic drive belt tensioning

  Light, consistent re-tensioning increases the service life of the belts and shaft bearings.

• Compensator

  

  This controller in the carburettor prevents the fuel-air mixture getting richer as the air filter becomes clogged. The correct quantity of fuel is delivered to the carburettor depending on the quantity of air passing through the air filter. This keeps the fuel/air ratio in the combustion mixture constant and hence also the engine power. The filter doesn't need to be cleaned until an appreciable drop in power occurs.

• Decompression valve

  

  The decompression valve allows some of the compression pressure in the cylinder to escape, so less force on the starter rope is needed.

• Ergonomic grip position

  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.

Additional features

• STIHL ElastoStart

  STIHL ElastoStart reduces the shock caused by the compression of the engine during starting. The compression shock is taken away from the user's joints and muscles through a spring or rubber element in the starter handle.

• Cut-off saw cart

  Ideal wherever edges have to be cut with particular precision, where a certain cutting depth needs to be maintained, or for cutting long, linear stretches.

• TS 410 Compact and robust 3.2-kW cut-off saw (300mm/12" cutting wheel)
