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.
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.
OIL CONSUMPTION BASED ON NEED. The controlled-delivery oil pump reduces your chainsaw’s oil consumption by up to 50%. To use it, simply select the E position. For very long cutting attachments or very dry wood, an additional oil volume can be set by the user.
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.
INCREASES SERVICE LIFE. The HD2 filter protects your power tool’s engine against even the finest dust, ensuring a longer service life and reduced wear. The filter made from PET material has up to 70% finer pores than fleece and polyamide filters, and is also oil- and water-repellent. This also makes it easier to clean the filter. When needed, the filter cartridge can be easily replaced without tools.
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.
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.
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.
FOR LOWER FUEL CONSUMPTION AND HIGH PERFORMANCE. Thanks to STIHL four-channel technology, you can work with your power tool with very low fuel consumption and high performance. The four overflow channels guide the fuel-and-air mixture into the cylinder in a targeted and more compressed manner, which optimally burns the fuel and significantly increases the performance of the engine.
EFFORTLESS START-UP. The decompression valve makes it easier to start your power 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.
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.
MS 261 C-M petrol-driven chainsaw: Robust for forestry work
The STIHL MS 261 C-M petrol-driven chainsaw is ideally equipped for forestry work in low- and medium-density stands. The professional chainsaw is designed for versatile use. With a power-to-weight ratio of 1.6 kg/kW, it offers great agility and endurance, so you can prune trees and cut wood to length quickly and effectively. It even makes it easy to fell thinner trees.
The 3.0 kW (4.1 hp) STIHL 2-MIX engine delivers the power you need, with low fuel consumption. This petrol-driven chainsaw is equipped with STIHL M-Tronic, enabling you to work fast and with optimum engine performance at a constant maximum speed. This supports the start-up process and regulates ignition time as well as fuel metering. In conjunction with the STIHL Light 04 guide bar, the STIHL .325" RS Pro saw chain offers high cutting performance with reduced weight.
The STIHL Ematic system ensures that every drop of oil gets to exactly where it is needed, so that you can work for long periods and with as little interruption as possible. The operating time is also extended by the long-life air filter system featuring pre-separation routing and an HD2 air filter, for extended maintenance intervals.
