Product Description

Powerful 2.4 kW brush cutter for professional landscape maintenance applications. Large cutting diameter and optimised gear ratio. Improved mowing performance.
Technically enhanced gearbox includes updates to the sealing system, main bearing and lubricant circulation - meaning increased robustness and a long service life.

New deflector design makes storage easier and increases visibility of the cutting attachment whilst working.

STIHL M-Tronic

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.

STIHL ErgoStart (E)

STIHL ErgoStart cuts the effort required to start the tool by half, while the starter cord can be pulled at just one third of the normal force. A coil spring between the starter cord and the crankshaft smoothes out force peaks, making them virtually undetectable through the cord itself.

Reduced-emission engine technology

2-stroke engine with stratified charge. A fuel-free layer of air is created between the burned charge in the combustion chamber and the fresh charge in the crankcase, reducing the amount of fuel lost during the charge cycle. This results in more power with a lower weight, up to 20% lower fuel consumption than regular 2-stroke engines and significantly reduced exhaust emissions.

Bike handle

When used in conjunction with a harness, the bike handle enables a smooth mowing action. The bike handle allows the machine to be easily guided, making it ideal for working on large areas and thus reducing fatigue.

Multi-function handle

The one-hand multi-function handle means you can control your device easily and reliably with one hand. Since all the relevant control elements are integrated in it, the handle is suitable for both right and left-handers.

Manuel fuel pump

With the manual fuel pump, fuel can be pumped into the carburettor at the push of a thumb. It makes starting the machine easier after it has been idle for a long time.

Tool-free handle adjustment

The ergonomic bike handle can be adjusted without tools

Improved anti-vibration system

New rubber elements improve the anti-vibration system of the clearing saw, reducing the levels by more than 30% when at low speeds and partial load.

TOOL-FREE HANDLE ADJUSTMENT

SET THE BIKE HANDLE POSITION. You can individually adjust the ergonomic bike handle (mowing handle) using the central clamping device. Thanks to the tool-free handle adjustment, you do not need any tools for this. The bike handle can be rotated 90 degrees for transport and space-saving storage.

Tool-free handle adjustment

STOP BUTTON

RESTART WORK QUICKLY. With the stop button, you can switch off your tool quickly and easily for a short break, for example. As the button springs back to its original position after actuation, the engine is immediately ready to start again. This provides more comfort after breaks and increases your work efficiency.

Simplified starting system

WINTER SETTING SLIDE CONTROL

It is quick and easy to switch the setting from winter to summer using the slide control. Using the winter setting will prevent the air filter and carburettor from freezing. (similar to illustration)

25° gear angle

The new STIHL short shaft brushcutters provides a new transmission angle of 25° for even more comfort when using clearing saws.

25° angled gear head

LARGE FUEL TANK

The transparent fuel tank with a volume of 0.75 l ensures long working intervals with fewer fuel stops. The level is easily visible from the outside. Easy to refuel through a large, easily accessible tank opening. (similar to illustration)
