Stihl MS651 chainsaw

STIHL 2-MIX engine

High power with up to 20% less fuel consumption compared to conventional 2-stroke engines.

Improved anti-vibration system

Optimal comfort and control, even when using long guide bars. Approx. 50% fewer vibrations than the MS 650.

Easy-to-repair technology
Thanks to intelligent engineering, no computer software is needed to perform repairs.

HD2 filter

This air filter keeps even the finest dust away from the engine, ensuring particularly long service life. Thanks to its special material, the filter can be easily cleaned by washing, for example with STIHL Varioclean and warm water.

STIHL ElastoStart®

Due to compression pressure, jerky stresses occur when starting internal combustion engines. The damping element of the special ElastoStart starting handle alternately absorbs and releases force according to the compression pattern. The result is smooth, even starting.

Tool-free fuel caps

Special caps for opening and closing the tank cap quickly, easily, and without tools.

Decompression valve

The decompression valve is part of the easy start system. The valve must be pressed before starting to reduce compression pressure during starting, as well as to reduce the effort required to pull the starter cord. The decompression valve is semi-automatic; it must be pressed manually before starting, but then closes automatically.

STIHL Ematic system

Compared to conventional guides without Ematic, the STIHL Ematic system reduces chain lubricant consumption by up to 50%, depending on the type of wood and cutting attachment used. This system includes a STIHL Ematic or Ematic S guide bar, a STIHL Oilomatic saw chain, and a variable flow or reduced flow oil pump. As a result, practically every drop of chain lubricant is delivered exactly to the right place.

Side chain tensioner

The side-mounted chain tensioner allows easy and safe chain tensioning.

Controlled flow oil pump

Different bar lengths, wood types, and sawing techniques require different amounts of oil. The controlled flow oil pump allows the user to select exactly the right amount of oil for the job at hand.
