The STIHL MS 261 C-M chainsaw powered by a combustion engine with a PD3 saw chain is suitable for the construction industry. Equipped with a STIHL Duro 3 carbide-tipped cutting chain, it is ideal for working with dirty wood or close to the ground. Moreover, the STIHL Duro 3 carbide-tipped cutting chain stays sharp up to 10 times longer than conventional cutting chains. This professional chainsaw has been designed for versatile use.
Thanks to the STIHL 2-MIX engine with a power of 3.0 kW (4.1 hp), the STIHL MS 261 C-M provides the necessary power with low fuel consumption. The saw is equipped with STIHL M-Tronic, allowing you to work efficiently and with optimal engine performance at a constant maximum speed. The starting process is assisted, and the ignition timing and fuel metering are appropriately controlled. Together with the STIHL Light 04 guide bar, the STIHL MS 261 C-M with the Duro 3 cutting chain offers excellent cutting performance with reduced weight.
Thanks to the long-life air filter system with a pre-filter and HD2 air filter, the operating time is also extended, which increases the intervals between services.
The side chain tensioner allows safe, easy, and quick tensioning and replacement of the chain. The tensioning screw is accessible from the side through the chain sprocket cover.
The STIHL M-Tronic system ensures the highest device performance immediately after startup. The fully electronic engine management system regulates the ignition timing and fuel metering, taking into account external conditions such as temperature, altitude, and fuel quality.
It allows precise, needs-based lubrication. The E marking guarantees the delivery of the appropriate amount of oil in all working conditions. Professionals dose precisely. The pump allows a reduction in oil consumption of up to 50%.
The new HD2 filter is made of polyethylene and has pores up to 70% finer compared to fleece or polyamide filters, which in practice means filtering the finest dirt particles. The new filter is also waterproof, does not absorb oil, and can be easily cleaned. The round filter cartridge can be removed without tools.
The adjustment system in the carburetor, the compensator, through pressure equalization, ensures that despite increasing air filter contamination, engine power, exhaust quality, and fuel consumption remain almost unchanged for a long time. Therefore, the air filter should only be cleaned after a clear drop in performance. This allows long periods of maintenance-free operation.
Carburetor preheating system
STIHL chainsaws equipped with a carburetor preheating system are reliable even when it is cold outside: in winter operating mode, heated air flows around the carburetor. This solution effectively prevents carburetor icing.
In four passage channels, the fuel-air mixture is swirled before ignition. This ensures better fuel combustion and significantly increases engine efficiency. Result: lower fuel consumption and high torque over a wide speed range.
When increasing the device's power, vibrations are generated that are particularly noticeable in the handle area. The buffer and spring elements of the STIHL anti-vibration system reduce the transmission of engine vibrations to the handle area and thus to the user's body. Effect: The device sits more comfortably in the hand, and work is much less tiring.
