• 
  CAPTIVE NUTS

  PROTECTION AGAINST LOSS The nuts are attached to the sprocket cover in a captive manner. This makes it impossible for the nuts to fall off and get lost when the cover is removed.
• 
  MANUAL DECOMPRESSION

  EFFORTLESS START-UP. The decompression valve makes it easier to start your power tool. When starting, you can allow some of the compressed mixture to escape from the cylinder by opening the valve. This protects the start-up system and reduces the amount of force required on the starter cord.
• 
  STIHL EMATIC SYSTEM

  REDUCES OIL CONSUMPTION. The STIHL Ematic system comprises a STIHL Ematic or Ematic S guide bar, a STIHL Oilomatic saw chain and a controlled-delivery oil pump. It ensures that the chain oil gets to where it is needed for lubrication. This allows you to reduce oil consumption by up to 50%. If you often work in dusty conditions or if you use long guide bars, you can quickly and easily increase the oil quantity at any time with the new oil pump system.
• 
  HD2-FILTER

  INCREASES SERVICE LIFE. The HD2 filter protects your power tool’s engine against even the finest dust, ensuring a longer service life and reduced wear. The filter made from PET material has up to 70% finer pores than fleece and polyamide filters, and is also oil- and water-repellent. This also makes it easier to clean the filter. When needed, the filter cartridge can be easily replaced without tools.
• 
  COMBI LEVER WITH STOP FUNCTION

  SIMPLIFIED OPERATION. Only one start position is required on the combi lever. Thanks to the stop function, once the machine is turned off the control lever immediately moves back into the operating position. This allows a warm machine to be restarted immediately.
• 
  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.
• 
  LONG-LIFE AIR FILTER SYSTEM FOR CHAINSAWS

  EXTENDED FILTER SERVICE LIFE. Pre-separation routing removes coarse, larger particles from the airstream before they can reach the actual filter. The HD2 filter keeps even fine dust away from the engine, ensuring a long engine service life, long cleaning intervals and easy maintenance of your chainsaw. When we refer to a long-life air filter system in chainsaws, this exclusively describes models that have pre-separation routing and an HD2 filter. With this system, you benefit from a significantly longer filter service life compared to conventional air filter systems.
• 
  CONTROLLED-DELIVERY OIL PUMP

  OIL CONSUMPTION BASED ON NEED. The controlled-delivery oil pump reduces your chainsaw’s oil consumption by up to 50%. To use it, simply select the E position. For very long cutting attachments or very dry wood, an additional oil volume can be set by the user.
• 
  STIHL 2-MIX Engine

  The STIHL 2-MIX engine is both powerful and economical. Separating the exhaust emissions from the unburnt gas minimises scavenging losses, and therefore increases the power output while reducing consumption.<br /><br />The two-stroke engine with STIHL 2-MIX technology saves up to 20% of fuel and reduces emissions by up to 70% compared to STIHL 2-stroke engines of the same performance class without 2-MIX technology.
• 
  STIHL M-TRONIC

  RELIABLE WORK WITH BEST PERFORMANCE. With the STIHL M-Tronic, you have the best performance from your implement right from the start. The fully electronic engine management regulates the ignition point and fuel metering in every work situation, taking into account external conditions such as temperature, altitude and fuel quality.
• 
  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.
• 
  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.
• 
  TOOL-FREE FUEL CAP FOR OIL AND FUEL TANKS

  QUICK AND EASY TO USE. With tool-free fuel cap, you can open and close oil and fuel tanks in just a few simple steps, thanks to a bayonet closure.
