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

Instruction is necessary to recognise or assess the dangers of a chainsaw. We ask that you must wear protective clothing and equipment. And you must understand Torne Valley isn’t responsible for any damage inflicted to yourself, others or property. If anything is unclear, we order the chainsaw via Click & Collect and pickup up the chain saw from your local Torne Valley store. Don’t forget you can also call us about STIHL Chainsaw if the instructions are unclear.
