  STIHL 2-MIX ENGINE

  HIGHLY POWER-EFFICIENT. With the STIHL 2-MIX engine, you can reduce exhaust emissions and fuel consumption, and therefore operating costs. This 2-stroke engine is low-maintenance and uses fuel efficiently even at high power levels. Use a mixture of petrol and engine oil as fuel. The STIHL 2-MIX engine complies with the strict EU Stage V emissions directive.

• 

  SIDE-MOUNTED CHAIN TENSIONING

  FOR SIMPLE AND SECURE RE-TENSIONING. Side-mounted chain tensioning allows for protected, easy and quick chain tensioning and replacement. The tensioning screw is inserted laterally through the sprocket cover.

• 

  STIHL FOUR-CHANNEL TECHNOLOGY

  FOR LOWER FUEL CONSUMPTION AND HIGH PERFORMANCE. Thanks to STIHL four-channel technology, you can work with your power tool with very low fuel consumption and high performance. The four overflow channels guide the fuel-and-air mixture into the cylinder in a targeted and more compressed manner, which optimally burns the fuel and significantly increases the performance of the engine.

• 

  COMPENSATOR

  REDUCED MAINTENANCE. The compensator is a control system in the carburettor, which uses pressure compensation to ensure that engine performance, exhaust gas quality and fuel consumption remain virtually constant over a long period of time, despite increasing contamination of the air filter. You do not need to clean the air filter until there is a noticeable drop in performance. This means that you can work for a long time without maintenance.

• 

  STIHL ANTI-VIBRATION SYSTEM

  FOR MORE PLEASANT WORK. Vibrations can occur when you put your power tools through their paces, and these are particularly noticeable in the grip area. The buffer and spring elements of the STIHL anti-vibration system reduce the transmission of engine vibrations to the handle area and therefore to your body. The result is that your power tool is more comfortable to hold and your work is much less tiring.

• 

  Single-lever master control

  All important functions such as start, choke, throttle and stop are operated via a single lever.

• 

  Tool free fuel caps

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

Retrofitted equipment

• 

  STIHL ElastoStart

  Due to compression pressure, jerky stresses occur when starting internal combustion engines. The damping element in the ElastoStart special starter grip alternately absorbs and releases force according to the compression pattern. The result is smooth, even starting.

• 

  STIHL QUICK CHAIN TENSIONING

  RE-TENSION THE SAW CHAIN TOOL-FREE. Thanks to STIHL Quick Chain Tensioning, you can tension your saw chain quickly and without tools, thanks to the adjusting wheel. Turning the adjusting wheel to the left releases tension on the saw chain, and turning the adjustment wheel to the right tensions the saw chain. The guide bar will be automatically secured when you tighten the sprocket cover.
