A spring between the starter cord reel and crankshaft relieves the strain when starting, meaning that excessive pulling on the cord is no longer needed. The result is a convenient starting procedure with practically.

The two-stroke engine with STIHL 2-MIX technology saves up to 20% of the fuel and reduces emissions by up to 70 % compared to STIHL 2-stroke engines of the same performance class without 2-MIX technology.

Side-mounted chain tensioning makes it easy to tension the chain safely.

Special caps to open and close the tank cap quickly, easily, and without tools.

The carburetor can be accessed without tools, so you can clean the air filter in a single step.

Precisely calculated buffer zones minimize the transfer of engine and saw chain vibrations to the front and rear handles. The chainsaw, therefore, runs noticeably smoother. This allows the user to save their strength and work longer.

This controller in the carburetor prevents the fuel-air mixture from getting richer as the air filter becomes clogged. The correct quantity of fuel is delivered to the carburetor 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.

Four overflow channels swirl the fuel-air mix before ignition, allowing for optimum combustion and highly efficient performance. The result is lower fuel consumption and high torque across a broad rpm range.

Compared 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. 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. As a result, virtually every drop of chain lubricant is delivered to exactly the right spot.
