STIHL MS 391 Chainsaw


The STIHL MS 391 is an easy to manage, a high-torque chainsaw that has been designed for improved performance and comfort when being used for harvesting wood or sawing firewood. It has high torque over a wide range of speeds and uses up to 20% less fuel and gives out up to 50% fewer emissions compared to the previous model which did not feature STIHL's 2-MIX technology.

Instruction is necessary to recognize or assess the dangers of a chainsaw. Please wear protective clothing and equipment.

If anything is unclear, we recommend to order the chainsaw via Click & Collect and pickup up the chainsaw from us.

Features

  • 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.
  • 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.
  • Anti-vibration system - Intense vibration at the handles of power tools can lead to long-term effects on blood vessels in the hands and arms. STIHL has therefore developed an effective anti-vibration system whereby the oscillations from the machine's engine are dampened which significantly reduces vibrations at the handles.
  • 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.
  • Compensator - This controller in the carburettor prevents the fuel-air mixture from 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.
  • Variable-displacement oil pump - Allows a precise, demand-based delivery of oil. It's possible to reduce oil production by up to 50% in the E position. For very long cutting attachments or very dry wood, an additional volume of oil can be added by the user. similar to illustration.
  • Single-lever master control - All important functions such as start, choke, throttle and stop are operated via a single lever.
  • Sidechain tensioner - The tensioning screw can be found on the side of the chainsaw through the sprocket cover. This removes the need for contact with the sharp saw chain.
  • Ematic chain lubrication system - The Ematic chain lubrication system ensures pinpoint lubrication of the saw chain links and guide bar rails. When used with STIHL OILOMATIC saw chain, it will provide maximum lubrication, longer wear and less oil consumption than conventional methods of chain lubrication. The Ematic system can reduce bar oil consumption by up to 50%.
  • Tool-free filler caps - Special catches on the fuel and oil tanks for easy opening and locking without the need for tools.
