Specifications

Top of the range, high torque farmer chainsaw
Great for felling firewood and for building with wood. Long-life air filter service life for very long filter service life, economical 2-MIX engine, and decompression valve for effortless starting.

Standard equipment
  • STIHL 2-MIX engine
  • 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.


  • Carburettor heating (V)
  • By changing the chain saw from summer to winter operation, the intake air is pre-heated over the engine fins. This ensures that the carburettor does not ice up and you can continue working in freezing temperatures.


  • Controlled-delivery oil pump
  • Different bar lengths, wood types and sawing techniques require different amounts of oil. The controlled-delivery oil pump allows the user to select just the right amount of oil for the job at hand.


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


  • 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.


  • Advanced combustion technology
  • 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.


  • 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 is part of the easy starting system. The valve should be pressed before starting to reduce the compression pressure when starting, as well as reducing the effort needed to pull the starter rope. The decompression valve is semi-automatic; it must be pressed manually before starting, but then closes automatically.


  • STIHL anti-vibration system
  • Precisely calculated buffer zones minimise 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.


  • STIHL Ematic System
  • 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.


  • Single-lever master control
  • All important functions such as start, choke, throttle and stop are operated via a single lever.
