Overview

STIHL MS 391 CHAIN SAW 20

TOP OF THE RANGE, HIGH TORQUE CHAIN SAW FOR RUGGED FARM USE

The MS 391 gas chainsaw combines strong cutting performance with comfort, for farmers, tradespeople and landscapers. The main areas of application for this power tool include cutting firewood, landscape maintenance and cutting construction timber. The STIHL MS 391 chainsaw impresses with an output of 3.3 kW (4.5 hp) and achieves an optimal power-to-weight ratio of 1.9 kg/kW. The chainsaw is powered by an economical and powerful STIHL 2-MIX engine. The STIHL MS 391 features a decompression valve that significantly reduces the pulling force on the starter cord, so that you can start the gas-driven chainsaw as effortlessly and easily as possible. Other features of the gas chainsaw include:

  • A controlled-delivery oil pump for demand-based delivery of oil. This means that lubrication can be optimised for very long cutting attachments or very dry wood, and oil consumption can be reduced in other cases. The STIHL Ematic system ensures that every drop of oil reaches exactly the places it is needed in a targeted manner.
  • The routing pre-separator removes coarse dirt particles, relieving strain on the filter itself. You can also retrofit your MS 391 with an HD2 air filter, thereby upgrading it with a long-life air filter system. This will allow you to work for significantly longer without interruption, and reduces the number of filter cleanings required.

STIHL MS 391 CHAIN SAW 20STIHL ANTI-VIBRATION SYSTEM

FOR MORE PLEASANT WORK. Vibrations can occur when you put your power tools through their paces, and these are particularly noticeable in the grip area. The buffer and spring elements of the STIHL anti-vibration system reduce the transmission of engine vibrations to the handle area and therefore to your body. The result is that your power tool is more comfortable to hold and your work is much less tiring.

STIHL MS 391 CHAIN SAW 20STIHL 2-MIX ENGINE

HIGHLY POWER-EFFICIENT. With the STIHL 2-MIX engine, you can reduce exhaust emissions and fuel consumption, and therefore operating costs. This 2-stroke engine is low-maintenance and uses fuel efficiently even at high power levels. Use a mixture of petrol and engine oil as fuel. The STIHL 2-MIX engine complies with the strict EU Stage V emissions directive.

STIHL MS 391 CHAIN SAW 20STIHL FOUR-CHANNEL TECHNOLOGY

FOR LOWER FUEL CONSUMPTION AND HIGH PERFORMANCE. Thanks to STIHL four-channel technology, you can work with your power tool with very low fuel consumption and high performance. The four overflow channels guide the fuel-and-air mixture into the cylinder in a targeted and more compressed manner, which optimally burns the fuel and significantly increases the performance of the engine.

STIHL MS 391 CHAIN SAW 20COMPENSATOR

REDUCED MAINTENANCE. The compensator is a control system in the carburettor, which uses pressure compensation to ensure that engine performance, exhaust gas quality and fuel consumption remain virtually constant over a long period of time, despite increasing contamination of the air filter. You do not need to clean the air filter until there is a noticeable drop in performance. This means that you can work for a long time without maintenance.

STIHL MS 391 CHAIN SAW 20TOOL-FREE FUEL CAP FOR OIL AND FUEL TANKS

QUICK AND EASY TO USE. With tool-free fuel cap, you can open and close oil and fuel tanks in just a few simple steps, thanks to a bayonet closure.

STIHL MS 391 CHAIN SAW 20MANUAL DECOMPRESSION

EFFORTLESS START-UP. The decompression valve makes it easier to start your power tool. When starting, you can allow some of the compressed mixture to escape from the cylinder by opening the valve. This protects the start-up system and reduces the amount of force required on the starter cord.

STIHL MS 391 CHAIN SAW 20STIHL EMATIC SYSTEM

REDUCES OIL CONSUMPTION. The STIHL Ematic system comprises a STIHL Ematic or Ematic S guide bar, a STIHL Oilomatic saw chain and a controlled-delivery oil pump. It ensures that the chain oil gets to where it is needed for lubrication. This allows you to reduce oil consumption by up to 50%. If you often work in dusty conditions or if you use long guide bars, you can quickly and easily increase the oil quantity at any time with the new oil pump system.

STIHL MS 391 CHAIN SAW 20CONTROLLED-DELIVERY OIL PUMP

The exact chain oil output can be adjusted manually for varying conditions, allowing for a reduction of up to 50%.

STIHL MS 391 CHAIN SAW 20SIDE-MOUNTED CHAIN TENSIONING

FOR SIMPLE AND SECURE RE-TENSIONING. Side-mounted chain tensioning allows for protected, easy and quick chain tensioning and replacement. The tensioning screw is inserted laterally through the sprocket cover.
