Stihl MS 261 C-M Forestry Petrol Chainsaw 18 inch Bar 50.2cc
Petrol chainsaw for Forestry work.
The STIHL MS 261 C-M petrol chainsaw is the perfect tool for small to medium tree maintenance work. 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.
The decompression valve is part of the easy starting system. 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 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, a 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.
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.
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.
Intense vibration at the handles of power tools can lead to long-term effects on blood vessels in the hands and arms. STIHL has therefore developed an effective anti-vibration system whereby the oscillations from the machine's engine are dampened which significantly reduces vibrations at the handles.
Pre-separation air filtration system
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.
