MS 391 petrol chain saw: a powerful all-rounder
For farmers, tradesmen and landscapers, the MS 391 petrol chainsaw combines high cutting performance with comfort. The main areas of use are sawing firewood, landscape maintenance and cutting timber. The STIHL MS 391 chainsaw has an output of 3.3 kW (4.5 hp) and achieves an optimum power-to-weight ratio of 1.9 kg/kW. The chainsaw is driven by the economical and powerful STIHL 2-MIX motor. To make starting the petrol chainsaw as easy and stress-free as possible, the STIHL MS 391 is equipped with a pressure reducing valve that significantly reduces the tension on the starting cable. Other features of the petrol chainsaw include:
The adjustable oil volume pump pumps the required amount of oil as needed. This optimizes lubrication even when cutting times are long or the wood is very dry, and reduces oil consumption in other situations. The STIHL Ematic system ensures that every drop of oil goes exactly where it is needed.
Pre-separation removes coarse dirt particles and thus reduces the load on the filter. If you add an HD2 air filter to your MS 391, it will have a long-lasting air filtration system. This significantly increases your uninterrupted working time and reduces the frequency of filter cleaning.
