Stihl Chainsaw MS 261 C-M

• The STIHL MS 261 C-M chainsaw is perfectly equipped for forestry work in weak and medium-density woods. For this reason, the professional chainsaw is designed for versatile use
• With a power-to-weight ratio of 1.6 kg/kW, you can work particularly agilely and resiliently. This way, you can quickly and effectively perform limbing and tree cutting. Even felling thin trees is easy
• The powerful STIHL 2-MIX engine with 3.0 kW (4.1 hp) delivers the necessary power with low consumption. To work quickly and with optimal engine performance at a constant maximum speed, this chainsaw is equipped with STIHL M-Tronic
• This system supports starting and regulates ignition timing and fuel dosing
• The STIHL .325"-RS Pro chain, together with the STIHL Light 04 guide bar, offers high cutting capacity with reduced weight
• To ensure you can use the power long-term and with minimal interruptions, the STIHL Ematic system ensures every drop of oil reaches exactly where it is needed
• Operating time is also extended by the long-life air filtration system with pre-separation and the HD2 air filter. This equipment ensures extended maintenance intervals

EQUIPMENT

Long-life air filter with pre-filtration
This innovative system allows for a significantly longer filter lifespan. Thanks to the pre-filtration, it removes coarser dirt particles, reducing the workload of the main filter. The chainsaw can operate longer without needing filter cleaning compared to a chainsaw without this type of filter.

HD2 filter
The new HD2 filter with polyethylene filter material has pores 70% finer than felt and polyamide filters, enabling it to filter even the finest dust particles. Additionally, it is oil-repellent, making it easy to clean. In an instant, the PET-coated filter core can be assembled and disassembled without the use of tools

Compensator
Allows a constant fuel-air mixture even when dirt builds up in the air filter

ElastoStart
Thanks to the exclusive STIHL ElastoStart starter handle, combined with the manual fuel pump and decompression valve, kickback during starting is significantly reduced

Ematic Chain Lubrication System
Depending on the bar type and wood type, the STIHL Ematic system reduces chain oil consumption by up to 50%. It consists of an Ematic bar, Oilomatic chain, and an adjustable low-flow oil pump. This ensures the lubricant is delivered precisely and with minimal loss exactly where it is needed

Anti-vibration System
Specially positioned damping zones reduce the transmission of vibrations from the engine and chain to the handle and grip

Tool-free Fuel Cap
Special caps for the fuel tank and oil tank allow easy opening and closing without difficulty

Side Chain Tensioner
The chain is tensioned laterally via the sprocket. This avoids any contact between the operator’s hand and the sharp chain

STIHL M-Tronic (M)
Fully electronic fuel metering and ignition timing adjustment. The STIHL M-Tronic (M) system ensures optimal engine performance, constant speed, and excellent acceleration behavior in every operating state. Manual carburetor adjustment is no longer necessary.

Adjustable oil pump
Different cutting lengths, wood types, and working techniques require varying amounts of oil. The adjustable oil pump allows precise regulation of the oil flow rate according to your needs. It is possible to reduce the oil supply by up to 50%

Kombi lever with stop button
The lever automatically returns to the operating position (I) after stopping

Decompression valve
The decompression system automatically opens the intake valve. This absorbs pressure peaks and reduces the force needed on the starter rope
