A top-of-the-range, high-torque chainsaw.
The MS 391 is an easy-to-manage chainsaw that offers improved performance and user comfort for jobs such as harvesting wood or sawing firewood. With a choice of 16 inch (40 cm), 18 inch (45 cm) or 20 inch (50 cm) bar lengths.
Advanced combustion technology provides highly efficient performance, lower fuel consumption and high torque across a broad rpm range. The 3.3kW STIHL 2-MIX engine also offers up to 50 percent lower emissions and up to 20 percent less fuel consumption compared to non-2-MIX equivalents. A compensator in the carburettor helps to keep the fuel/air ratio and engine power constant, even as the air filter becomes clogged. This gives you excellent performance that you can rely on.
The chain tensioner has been positioned on the side of the saw through the sprocket cover, which removes the need for contact with the sharp saw chain. Another feature that aids ease-of-use is the tool free filler caps. There are special catches on the fuel and oil tanks that make for easy opening and locking, so you can effortlessly top up your machine with no tools required. All of the MS 391's important operating functions, such as stop, start, choke and throttle, are collected onto a single lever, meaning this saw takes less effort to use, and is more comfortable to work with.
Efficient & comfortable design
As well as STIHL's 2-MIX engine, which provides fuel and emission efficiencies, the MS 391 uses the Ematic chain lubrication system. This ensures pinpoint lubrication of the saw chain links and guide bar rails to give longer wear and reduce bar oil consumption by up to 50 percent. A variable-displacement oil pump allows precise, demand-based delivery of oil, again reducing oil consumption in this model. Due to STIHL's anti-vibration technology, the MS 391 is also a pleasure to work with. Engine oscillations are dampened, resulting in significantly reduced vibrations at the handles.
