Very powerful, this STIHL MS 660 chainsaw is designed for heavy felling. Its nervous and fast engine makes it a very popular machine for its speed.

Universal lever control

Machine functions, such as cold or hot start, normal operation, and stop, are controlled by a single lever. The control is therefore very convenient and safe. In addition, located to the left of the rear handle, it is accessible with the tip of the thumb without having to let go of the handle.


Whatever the level of clogging of the air filter, the STIHL compensator maintains constant the dosage between the air and the fuel entering the engine. Thus, the engine always develops optimized power. In addition, maintenance intervals are longer and costs are reduced.

ElastoStart STIHL

The Elastostart consists of a shock absorber located between the rope and the starter handle. It absorbs the jolts, due to compression, during starting. Thus, engine starts are smoother and require less effort. This STIHL element brings you comfort and safety.

Automatic return decompressor

The decompressor reduces engine compression when starting. Thus the effort to be provided on the launcher is less. Getting started is then easier and more comfortable. The decompressor is a valve placed at the top of the cylinder. When opened at start-up, it releases some of the pressure in the cylinder. And from the first combustion, it closes automatically to allow the engine to deliver all its power.

Lubricating Ematic chains

Save oil with the Ematic system. Thanks to the combined action of the Ematic guide bar and the Oilomatic chain, every drop of oil is used to lubricate the cutting device where it is needed. This saves up to 50% chain oil depending on the length of the cutting device and the type of wood.

Adjustable flow oil pump

Allows precise optimization of oil flow according to needs. Setting to the E mark guarantees sufficient oil flow in any case. Professionals proceed to a more precise dosage. Up to 50% reduction in oil flow can be achieved.

Anti-vibration system

In order to reduce vibrations at the handles, STIHL has developed a highly effective anti-vibration (AV) system. The motor and the cutting device are completely suspended from the handles, either by springs or elastomer pads or even by a combination of these two components. This results in great working comfort, reducing the risk of blood circulation defect in the hands and arms.

Sidechain tensioner

Located on the side of the engine, the lateral chain tensioner avoids any contact with the chain or the claw when tensioning the chain. The operation is thus very safe and very easy to perform.

HD2 filter

The HD2 filter made of polyethylene has up to 70% finer pores than a membrane filter or polyamide filter. It is therefore able to filter extremely fine particles. In addition, it is water repellent and oil resistant and is therefore very easy to clean.
