Features

MS 261

Standard equipment

  • STIHL ElastoStart Zoom
    STIHL ElastoStart

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

  • STIHL 2-MIX ENGINE Zoom
    STIHL 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.

  • CARBURETTOR PRE-HEATING Zoom
    CARBURETTOR PRE-HEATING

    FOR RELIABLE OPERATION EVEN IN WINTER. Thanks to carburettor preheating, you can work reliably with your chainsaw even in winter. You can change the operation from summer to winter mode in just one simple step. In the winter setting, pre-heated intake air flows around the carburettor, preventing it from icing up.

  • CONTROLLED-DELIVERY OIL PUMP Zoom
    CONTROLLED-DELIVERY OIL PUMP

    OIL CONSUMPTION BASED ON NEED. The controlled-delivery oil pump reduces your chainsaw’s oil consumption by up to 50%. To use it, simply select the E position. For very long cutting attachments or very dry wood, an additional oil volume can be set by the user.

  • SIDE-MOUNTED CHAIN TENSIONING Zoom
    SIDE-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.

  • LONG-LIFE AIR FILTER SYSTEM FOR CHAINSAWS Zoom
    LONG-LIFE AIR FILTER SYSTEM FOR CHAINSAWS

    EXTENDED FILTER SERVICE LIFE. Pre-separation routing removes coarse, larger particles from the airstream before they can reach the actual filter. The HD2 filter keeps even fine dust away from the engine, ensuring a long engine service life, long cleaning intervals and easy maintenance of your chainsaw. When we refer to a long-life air filter system in chainsaws, this exclusively describes models that have pre-separation routing and an HD2 filter. With this system, you benefit from a significantly longer filter service life compared to conventional air filter systems.

  • HD2-FILTER Zoom
    HD2-FILTER

    INCREASES SERVICE LIFE. The HD2 filter protects your power tool’s engine against even the finest dust, ensuring a longer service life and reduced wear. The filter made from PET material has up to 70% finer pores than fleece and polyamide filters, and is also oil- and water-repellent. This also makes it easier to clean the filter. When needed, the filter cartridge can be easily replaced without tools.

  • STIHL FOUR-CHANNEL TECHNOLOGY Zoom
    STIHL 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.

  • COMPENSATOR Zoom
    COMPENSATOR

    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.

  • MANUAL DECOMPRESSION Zoom
    MANUAL 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 ANTI-VIBRATION SYSTEM Zoom
    STIHL 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 Ematic System Zoom
    STIHL Ematic System

    Compared to conventional bars without Ematic, the STIHL Ematic system reduces the consumption of chain lubricant by up to 50 %, depending on the type of wood and the cutting attachment used. This system comprises 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, virtually every drop of chain lubricant is delivered to exactly the right spot.

  • Single-lever master control Zoom
    Single-lever master control

    All important functions such as start, choke, throttle and stop are operated via a single lever.

  • CAPTIVE NUTS Zoom
    CAPTIVE NUTS

    PROTECTION AGAINST LOSS The nuts are attached to the sprocket cover in a captive manner. This makes it impossible for the nuts to fall off and get lost when the cover is removed.

  • Tool free fuel caps Zoom
    Tool free fuel caps

    Special caps to open and close the tank cap quickly, easily and without tools.
