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.

ADVANCE GRIP HANDLE

INNOVATIVE ERGONOMICS. The ADVANCE Grip handle has an innovative design to improve ergonomics over long working periods. The improved shape and the side-mounted locking lever supports intuitive operation. This gives you more options for adjusting your hand position depending on the work.

STIHL M-TRONIC

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.

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.

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.

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.

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.

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)

LONG AIR FILTER SERVICE LIFE

ENSURES LONG CHANGEOVER INTERVALS. Thanks to its long service life, you rarely need to change the easily accessible filter. This saves resources and reduces maintenance effort.
