2024 STIHL MS 391

2024 Stihl Petrol chainsaws for agriculture and horticulture MS 391

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.

Features may include:

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.
