Chainsaw | 6.4 kW 8.7 hp. The most powerful production chainsaw in the world
With a power of 6.4 kW (8.7 hp), the STIHL MS 881 not only has the most powerful STIHL 2-MIX engine of all STIHL chainsaws, but is also the most powerful production chainsaw in the world. This petrol chainsaw was developed for forestry workers and professionals in sawmills to provide reliable and effective support in felling, ripping and cross-cutting.
Starting the STIHL MS 881 petrol chainsaw is as easy as possible. That is why it is equipped with a decompression valve and STIHL ElastoStart to make starting significantly easier. The single-lever master control allows access to all functions with one hand, so you can always keep your right hand on the handle. The STIHL anti-vibration system effectively reduces vibrations on the handles, protecting your muscles and joints, while the HD2 polyethylene air filter filters even very fine dust, keeping the engine free of contaminants. The filter can be effectively cleaned and replaced without tools.
To avoid any possible contact of the hand with the saw chain or the spiked bumper, the chain tensioning knob is located on the side. With the stop button you can stop the saw at the press of a button and as soon as the STIHL MS 881 is stopped, it automatically sets itself in the starting position, so you can get to work immediately. The standard equipment of the saw includes a guide bar with a length of 90 cm and a Rapid Super chain with a pitch of 0.404.

ENSURES EASY AND SAFE TENSIONING. The side chain tensioner enables safe, easy and quick tensioning and replacement of the chain. The tensioning screw is accessible from the side through the chain sprocket cover.
Allows precise, needs-based lubrication. The E marking guarantees the supply of the right amount of oil in all working conditions. Professionals dose precisely. The pump allows oil consumption to be reduced by up to 50%.
The new HD2 filter is made of polyethylene and has pores that are up to 70% finer compared to fleece or polyamide filters, which in practice means filtering the finest particles of dirt. The new filter is also waterproof, does not absorb oil and can be easily cleaned. The round filter cartridge can be removed without tools.
The adjustment system in the carburetor, the compensator, by equalizing pressure, ensures that despite increasing dirt on the air filter, engine power, exhaust quality and fuel consumption remain almost unchanged for a long time. Therefore, the air filter only needs to be cleaned after a clear drop in parameters. This makes maintenance-free operation possible for a long time.
Thanks to the tool-free tank closure, the oil and fuel tank can be easily opened and closed with a bayonet closure.
The STIHL Ematic system consists of the STIHL Ematic or Ematic S guide bar, the STIHL Oilomatic saw chain and an oil pump with adjustable flow. It guarantees that chain oil gets where it is needed for lubrication. This allows oil consumption to be reduced by up to 50%. When working in very dusty conditions or when using long guide bars, the amount of oil can be easily and quickly increased at any time thanks to the new oil pump system.
STIHL chainsaws equipped with a carburetor preheating system are reliable even when it is cold outside: in winter operating mode, heated air flows around the carburetor. This solution effectively prevents the carburetor from icing up.
The decompression valve makes starting the device easier. Opening the valve during starting allows part of the compressed mixture to be released from the cylinder. This protects the starting system and requires less force on the starter rope.
ENSURES MORE COMFORTABLE WORK. When the power of the device increases, vibrations are generated that are particularly noticeable in the handle area. The buffer and spring elements of the STIHL anti-vibration system reduce the transmission of engine vibrations to the handle area and thus to the user's body. Effect: The device sits more comfortably in the hand and work is much less tiring.
