Stihl MS 241 C-M Chainsaw


Stihl MS 241 C-M Chainsaw

With M-Tronic Engine Management

Professional petrol chainsaw 40cm/16'' bar

The STIHL MS 241 C-M professional chainsaw is compact and raring to go, with M-Tronic as standard. Fuel metering is controlled electronically and automatically adjusts to environmental conditions, to deliver optimal engine performance.

Other great features include:

  • An easy to clean HD2 filter
  • New STIHL professional anti-vibration system
  • Chain tensioner
  • 'Patented' captive nuts on the chain sprocket cover
  • Easy access quick-lock bayonet fittings on one-piece shroud and memory function.

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.

Long-life air filter system with HD2 filter

The new professional Stihl chainsaws will win you over with a filter life that is five times longer. They are equipped with a long-life air filter system that removes coarse dirt particles by pre-separation. The new HD2 filter made from polyethylene filter material filters out the finest dust particles and is easy to clean. The PET-covered round filter cartridge can be replaced quickly and without tools. The radial seal minimises the amount of dirt in the carburettor - similar to illustration.

STIHL anti-vibration system

Intense vibration at the handles of power tools can lead to longer-term effects of blood vessels in the hands and arms. STIHL have therefore developed an effective anti-vibration system where by the oscillations from the machines engine are dampened which significantly reduces vibrations at the handles.


This controller in the carburettor prevents the fuel-air mixture getting richer as the air filter becomes clogged - 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.

Controlled-delivery oil pump

The exact chain oil output can be adjusted manually for varying conditions, allowing for a reduction of up to 50%.

Decompression valve

The decompression valve is part of the easy start-system. The valve should be pressed before starting in order to reduce the compression pressure when starting, as well as the effort needed to pull the starter rope. The decompression valve is semi-automatic, meaning that it must be pressed manually before starting, but then closes automatically.

Advanced combustion technology

Four overflow channels swirl the fuel-air mix before ignition, allowing for optimum combustion and highly efficient performance. The result: lower consumption and high torque across a broad rpm range.

Single-lever master control

All important functions such as start, choke, throttle and stop are operated via a single lever.
