MS 261 C-M VW Petrol Chainsaw

Standard features

• STIHL M-Tronic (M)

  This fully electronic engine management system adjusts ignition timing and fuel metering in all operating modes. It also takes external conditions such as temperature, altitude and fuel quality into account. It ensures consistent engine performance, a constant maximum speed and superb acceleration. M-Tronic makes manual carburettor adjustments unnecessary. Thanks to electronic cold/warm start recognition, now there is only one start position on the combi-lever. The engine starts after fewer pulls and with no change of position, and can immediately accelerate up to speed - even after a cold start. M-Tronic also remembers the settings from the last time the tool was used. So when external conditions are the same, optimal engine performance is available every time you start up again.

• Heated handles (W)

  These provide additional comfort in cold weather and can be engaged with a switch on the left handle as required.

• Carburetor heating

  N/A

• STIHL 2-MIX-Engine

  1-in-4 channel technology. The economical STIHL 2-MIX engine with 1-in-4channel technology features a high torque over a wide speed range. The chainsaw provides fuel savings of up to 20% compared to STIHL two-stroke engines in the same performance class without 2-MIX technology. Exhaust emissions are reduced by up to 50%.

• HD2 filter

  The HD2 filter is made from polyethylene filter material with up to 70% finer pores than fleece and polyamide filters to trap even very fine dust. In addition, it is oil and water-repellent and thus very easy to clean. The PET-covered filter cartridge with quick-release lock enables the filter to be assembled and disassembled in next to no time, without using tools.

• Decompression valve

  The decompression valve is part of the easy starting system. The valve should be pressed before starting to reduce the compression pressure when starting, as well as reducing the effort needed to pull the starter rope. The decompression valve is semi-automatic; it must be pressed manually before starting, but then closes automatically.

• STIHL ElastoStart

  STIHL ElastoStart reduces the shock caused by the compression of the engine during starting. The compression shock is taken away from the user's joints and muscles through a spring or rubber element in the starter handle.

• Side chain tensioner

  The tensioning screw can be found on the side of the chain saw through the sprocket cover. This removes the need for contact with the sharp saw chain.

• Variable-displacement oil pump

  Allows a precise, demand-based delivery of oil. It's possible to reduce oil production by up to 50% in the E position. For very long cutting attachments or very dry wood, an additional volume of oil can be added by the user. similar to illustration.

• Tool free filler caps

  Special catches on the fuel and oil tanks for easy opening and locking without the need for tools.

• Pre-separation air filtration system

  STIHL long-life air filtration systems with pre-separation achieve perceptibly longer filter life compared with conventional filter systems. Air drawn in is swirled. The larger, heavier particles are ejected. The pre-cleaned air is routed to the air filter via the pre-separator duct.

• Anti-vibration system

  Intense vibration at the handles of power tools can lead to long-term effects on blood vessels in the hands and arms. STIHL has therefore developed an effective anti-vibration system whereby the oscillations from the machine's engine are dampened which significantly reduces vibrations at the handles.

• Combi lever

  As M-Tronic has electronic cold and warm start recognition, only one start position is needed on the combi lever. The exact amount of fuel is supplied on demand. You do not need to know about the status of your chainsaw and can apply full throttle straight away - even with a cold start. Because the saw is warmed up by optimum acceleration in a few seconds.

• Stop button function

  After the machine is turned off, the control lever immediately moves back into the operating position. This allows a warm machine to be restarted again immediately.

• Captive nuts

  When changing the cutting attachment, you will not risk losing the nuts on the sprocket. The MS 261 is the first STIHL chainsaw to be equipped with the captive nuts. A great advantage for all users.

• Advanced combustion technology

  Four overflow channels swirl the fuel-air mix before ignition, allowing for optimum combustion and highly efficient performance. The result is lower fuel consumption and high torque across a broad rpm range.

• Carburettor heating (V)

  By changing the chain saw from summer to winter operation, the intake air is pre-heated over the engine fins. This ensures that the carburettor does not ice up and you can continue working in freezing temperatures.

• Ematic chain lubrication system

  The Ematic chain lubrication system ensures pinpoint lubrication of the saw chain links and guide bar rails. When used with STIHL OILOMATIC saw chain, it will provide maximum lubrication, longer wear and less oil consumption than conventional methods of chain lubrication. The Ematic system can reduce bar oil consumption by up to 50%.

• MotoMix

  STIHL MotoMix is our patented premixed fuel, specially blended for ultimate performance. This 50:1 ready-mixed fuel is a combination of premium non-ethanol, high-octane motor fuel for all STIHL 2-stroke engines which gives you optimum performance, excellent cold start properties, maximum acceleration over the entire rpm range and perfect running characteristics even with a sudden rev change. With STIHL HP ultra premium oil for exceptional engine lubrication and extreme cleanliness, fully synthetic and biodegradable for optimal performance and long service life. User- and engine-friendly thanks to fewer emissions (free from ethanol; almost no olefins and aromatic compounds). Can be kept in storage for up to five years. Reliable top performance – STIHL 2-stroke engines and STIHL MotoMix are made for each other; all conceivable applications have been put through rigorous testing.

• Varioclean

  Water based, alkaline detergent specifically for dissolving and removing burnt-in resin and oil residue from your machine, and cleaning your tool’s housing, HD2 filter, wire mesh filter or PA filter. The detergent is biodegradable. Avoid contact with the eyes and keep out of reach of children.

  To use Varioclean, first wait for your machine to cool down. Then, spray it onto the surface of the part you are cleaning and leave it for a maximum of 5 minutes, so the cleaner is not allowed to dry. Then, wash it off with water and wipe with a cloth to dry. We recommend you wear safety glasses when doing this.
