An easy-to-manage, top-of-the-range chainsaw.
Offering high torque over a wide range of speeds, the MS 391 also gives improved performance and excellent levels of user comfort when harvesting wood or sawing firewood. Available with a choice of 16 inch (40 cm), 18 inch (45 cm) or 20 inch (50 cm) bar lengths.
A high-performing chainsaw
This model is powered by a 3.3kW STIHL 2-MIX engine, which not only offers high power but up to 20 percent lower fuel consumption and up to 50 percent reduced exhaust emissions compared to non-2-MIX machinery. Advanced combustion technology also offers benefits to fuel consumption, while providing high torque across a broad rpm range. A compensator in the carburettor keeps the fuel/air ratio in the combustion mixture constant, and so also maintains the engine's power even as the air filter becomes clogged.
An easy machine to handle
Special catches on the fuel and oil tanks allow for easy opening and locking without the need for tools. This means you can top up oil and fuel without hassle and with fewer spillages. The machine's chain tensioner is located on the side of the saw, through the sprocket cover, removing the need for contact with the saw chain. All of the saw's important functions (such as start, choke, throttle and stop) are operated using a single lever, increasing operating comfort and making the machine simpler to use.
Comfortable & efficient
Anti-vibration technology dampens the engine's oscillations to reduce vibrations present at the handles, ensuring the MS 391 is comfortable to operate for long periods. In terms of efficiency, as well as the 2-MIX engine, the Ematic chain lubrication system can reduce bar oil consumption by up to 50 percent. It also provides maximum lubrication and longer wear, so is a great addition, particularly when combined with the variable-displacement oil pump.
