Optimal engine performance at all times

STIHL M-Tronic (M) engine management

The STIHL MS 261 C-M chainsaw offers professionals outstanding performance right from the word go. No matter if you're just starting work, are already on the job or restarting the chainsaw after a break, M-Tronic adjusts the ignition timing in all operating modes. It also precisely and electronically meters the fuel supply. It even takes into account external conditions such as temperature, elevation and fuel quality. M-Tronic also saves your previous settings on an electronic chip and restores them when you restart the chainsaw. So when external conditions are the same, full engine performance is at your disposal after every new start – all without changing the settings or making other adjustments. This means that you save time and get the job done faster.

Combi-lever with a stop button function

Thanks to the M-Tronic's ability to electronically distinguish between a cold or warm start, there is only one start position (▲) on the combi-lever. The exact amount of fuel needed for each kind of start-up is provided automatically. So you don't have to worry about what operational mode your chainsaw is in – with this little beauty you can power up to full speed straight away, even after a cold start.

Powerful, clean and efficient

2-stroke engine with 2-MIX technology

Powerful torque and lower emissions – now possible thanks to the STIHL 2-MIX engine with 50.2 cm³ displacement and an output of 2.9 kW. This 2-stroke engine with 2-MIX technology combines a cylinder with four-channel technology and a stratified charge system. The result: high torque over a wide rpm range – with up to 50% fewer exhaust emissions and fuel consumption that's up to 20% lower compared to STIHL two-stroke engines of the same performance class without 2-MIX technology.

Low maintenance

Long-life air filter system with air routing and a HD2 filter

Long-life air filter system with air routing and HD2 filter

The MS 261 C-M chainsaw will win you over with its long filter life. It comes equipped with a long-life air filter system which uses air routing to remove larger particles of dirt, meaning the actual filter has less to do. The HD2 filter is made of polyethylene and its pores are up to 70% finer than those made of polyamide so it can stop even the most minute particles of dust.

Just one look under the hood

Simply open the three quick-release fasteners, take off the one-piece hood and you're ready to carry out three different maintenance jobs on the chainsaw: clean the air filter, check the spark plugs and clean the cylinder fins.

STIHL Ematic chain lubrication system

The oil pump can be adjusted to deliver just the right amount of oil to suit the cutting attachment you're using or the kind of wood with which you are working. A precisely measured amount of chain lubricant is delivered to exactly where it's needed. This reduces the amount of chain lubricant used by up to 50%, depending on the type of wood and the cutting attachment used.
