STIHL MS 261 C-M Chainsaw with M-Tronic 16" Bar Length

Very light, handy and powerful professional chainsaw. The electronic self-tuning engine management system means that the fuel supply is electronically controlled and the machine automatically adapts to operating and ambient conditions, ensuring optimal engine performance every time. The memory function remembers previous operating conditions and allows you to restart quickly after an extended break.

With easy-clean HD2 filter, controlled-delivery oil pump and practical features such as a stainless steel muffler, captive nuts on the sprocket cover and monocoque cover with three quick-release fasteners. The 2-MIX technology in the innovative STIHL MS 261 C-M ensures up to 20% less fuel consumption and up to 50% emissions reduction compared to the same power STIHL two-stroke engines without 2-MIX technology.

Instruction is necessary to recognize or assess the dangers of a chainsaw. Please wear protective clothing and equipment.

If anything is unclear, we recommend to order the chainsaw via Click & Collect and pickup up the chainsaw from us.

Key Features

  • 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 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, 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.
  • 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.
  • HD2 filter - The HD2 filter is made from polyethene 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.
  • 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.
  • 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.
  • Compensator - This controller in the carburettor prevents the fuel-air mixture from getting richer as the air filter becomes clogged. The correct quantity of fuel is delivered to the carburettor depending on the quantity of air passing through the air filter. This keeps the fuel/air ratio in the combustion mixture constant and hence also the engine power. The filter doesn't need to be cleaned until an appreciable drop in power occurs.
  • 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.
  • 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.
  • Sidechain 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.
  • 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%.
  • 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.
  • Tool-free filler caps - Special catches on the fuel and oil tanks for easy opening and locking without the need for tools.
