All-purpose professional petrol chainsaw

For forestry work in small and medium-density stands

Easy starting and optimised engine performance with STIHL M-Tronic

MS 261 C-M Petrol Chainsaw: Powerful 3.0 kW forestry chainsaw with Light 04 bar

The STIHL MS 261 C-M petrol chainsaw is the perfect tool for small to medium tree maintenance work. This new version features a newly designed Light 04 guide bar as well as the new .325” RS Pro saw chain for improved cutting performance. The high performance .325” saw chain provides up to 20% more cutting performance compared to its predecessor (.325” RS) due to the narrower kerf. This light and well-balanced saw delivers plenty of power, whilst the M-Tronic technology controls the fuel and air mix at all times so the machine is always at optimum performance. The STIHL anti-vibration system significantly reduces vibrations at the handles for comfortable use of this petrol chainsaw throughout your working day.

The MS 261 C-M is a versatile, professional petrol chainsaw allowing you to run a selection of different bar lengths to suit your needs. It also includes useful features such as the easy-clean HD2 filter, adjustable oil delivery to the bar and chain, stainless steel muffler and captive nuts on the sprocket cover. The 2-MIX technology in the MS 261 C-M petrol chainsaw ensures up to 20% less fuel consumption and up to 50% less emissions compared to the equivalent STIHL two-stroke engines without 2-MIX technology.

Features

The pictures shown are sample photos. The actual appearance of the equipment features and their specific attachment to the product may differ from the pictorial representations, but will have the same functionality.

STIHL M-TRONIC

RELIABLE WORK WITH THE BEST PERFORMANCE. With STIHL M-Tronic, you’ll have the best performance from your work tool from the outset. Fully electronic engine management regulates the ignition timing and fuel metering in all work situations, taking into account external conditions such as temperature, altitude and fuel quality.

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.

MANUAL DECOMPRESSION

EFFORTLESS START-UP. The decompression valve makes it easier to start your 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.

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.

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.

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.

COMBI LEVER WITH STOP FUNCTION

SIMPLIFIED OPERATION. Only one start position is required on the combi lever. Thanks to the stop function, once the machine is turned off the control lever immediately moves back into the operating position. This allows a warm machine to be restarted immediately.

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.

CAPTIVE NUTS

When changing the cutting attachment, you will not risk losing the nuts on the sprocket.

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.

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.

TOOL-FREE FUEL CAP FOR OIL AND FUEL TANKS

QUICK AND EASY TO USE. With tool-free fuel cap, you can open and close oil and fuel tanks in just a few simple steps, thanks to a bayonet closure.

STIHL EMATIC SYSTEM

REDUCES OIL CONSUMPTION. The STIHL Ematic system comprises a STIHL Ematic or Ematic S guide bar, a STIHL Oilomatic saw chain and a controlled-delivery oil pump. It ensures that the chain oil gets to where it is needed for lubrication. This allows you to reduce oil consumption by up to 50%. If you often work in dusty conditions or if you use long guide bars, you can quickly and easily increase the oil quantity at any time with the new oil pump system.
