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.

Special caps to open and close the tank cap quickly, easily and without tools.Ģ-stroke engine with stratified charge. As a result, virtually every drop of chain lubricant is delivered to exactly the right spot.Īll important functions such as start, choke, throttle and stop are operated via a single lever. This system comprises a STIHL Ematic or Ematic S guide bar, a STIHL Oilomatic saw chain and a variable-flow or reduced-flow oil pump. This allows the user to save their strength and work longer.Ĭompared to conventional bars without Ematic, the STIHL Ematic system reduces the consumption of chain lubricant by up to 50 %, depending on the type of wood and the cutting attachment used. The chainsaw therefore runs noticeably smoother. Precisely calculated buffer zones minimise the transfer of engine and saw chain vibrations to the front and rear handles. This ensures that the carburettor does not ice up and you can continue working in freezing temperatures. All it takes is 2 fingers and a gentle pull action.īy changing the chain saw from summer to winter operation, the intake air is pre-heated over the engine fins. STIHL Easy2Start (E) cuts the effort required to start the tool by half, while the starter cord can be pulled at just one third of the normal force.
