NEW Stihl MS261 C-M Chainsaw 2020

Introducing the new 2020 version of the Stihl MS261 C-M Petrol chainsaw, the ideal tool for small or medium tree work. Upgrades include the new .325″ RS Pro saw chain, with an updated Light 04 guide bar – which means an amazing improvement in cutting performance.

• Upgraded bar and chain,
• Better fuel economy,
• M-Tronic technology,
• Lightweight and well balanced,
• Available with a 14″, 16″ or 18″ blade.

MS261 has better cutting performance than previous models

With this version of the Stihl MS 261 CM Petrol chainsaw, we have seen an impressive 20% increase in cutting performance (compared to .325″ RS). With this petrol chainsaw, you will also not lack for power. Designed to with a narrower cutting width (kerf), the blade will have less resistance to the wood, therefore, you can saw through at a much greater speed.

Additionally, this Stihl petrol chainsaw will always provide optimum power with the inbuilt M-Tronic technology, which, controls the air and fuel mixture at all time. The MS261 C-M is comfortable to use too, with Stihl’s anti-vibration system crucially reducing the judder. This means no more aching hands during long stints.

A versatile petrol chainsaw built for professional use

Notably, the MS261 C-M allows you to easily swap out different bar length to suit the job at hand – a 14-inch, 16-inch and 18-inch. 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.

Other practical features include:

• an easy to clean HD2 Filter,
• adjustable oil delivery to the bar and chain,
• stainless steel muffler,
• captive nuts on the sprocket,
• 2-Mix engine for 20% less fuel consumption.

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.

This MS261 petrol chainsaw’s economical STIHL 2-MIX engine with 1-in-4 channel 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%.

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.

Easy starting of the Stihl MS261

The decompression valve is part of the easy starting system of the MS261. 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 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.

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.

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.

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

Unstoppable operation with better efficiency.

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.

This controller in the carburettor prevents the fuel-air mixture 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.

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%.
