Features

Constant Power

CONSTANT POWER, REGARDLESS OF BATTERY CHARGE STATUS. With other brands of battery tools, the performance usually decreases during work as the battery discharges. This is not the case with STIHL cordless power tools with CONSTANT POWER. Thanks to the intelligent electronics, your STIHL power tool works with consistently high power.

Swivelling Mowing Unit

EFFICIENT CUTTING OF LAWN EDGES. To cut lawn edges comfortably, precisely and quickly, you can turn the mowing unit by 90° with a few simple movements. This means that vertical cuts for lawn edges can be made in a normal working position, and sharp contours along paths or flower beds can be easily cut out.

Adjustable Working Depth

COMFORTABLE TRIM UNDER OBSTACLES. The mowing unit can be angled in several stages, allowing you to comfortably adjust the grass trimmer to your own height and also to the working environment. This allows you to work particularly comfortably under obstacles such as benches.

Loop Handle

MORE COMFORT AS YOU WORK. It is easy to adjust the loop handle of this brushcutter to your own height simply by tilting it. Doing so allows you to work for longer without fatigue. The height can be adjusted without using any tools.

Ergonomic Control Handle With Speed Control

EASY ADJUSTMENT OF POWER TOOL PERFORMANCE. Quickly and conveniently adjust the speed of your power tool to the respective work situation. Doing so reduces energy consumption at low speeds, and in this way extends the battery runtime. The practical control handle with speed control allows you to make the relevant adjustment without having to change your grip or pause work.

Length-adjustable Shaft

FOR HIGH WORKING COMFORT. Thanks to the length-adjustable shaft, you can work very comfortably and with minimum strain on your back. To do so, simply adjust the shaft to your height and working method, without tools.

Softgrip Handle With Control Lever

FOR COMFORTABLE WORK. The softgrip handle integrates the control lever for switching on and off as well as a control lever lock, to make it easier to operate your battery brushcutter. Not only is it easy to grip, but it also absorbs some of the vibrations that arise during operation.

Spare Blade Storage

Up to 6 PolyCut blades can be stored on the unit and easily replaced when needed.

Flexible Spacer Bar

PROTECTS DURING MOWING. The spacer bar protects objects and plants as well as the cutting attachment. It means that when mowing, you can be certain of trimming precisely, without damaging plants, bark or objects. The cutting tool does not cut beyond the position of the bar. However, the front part of the spacer bar is made from flexible material, so that you can push against it if necessary and then get even closer to objects when trimming. This makes it possible to carry out clearing work in a controlled and thorough manner. You can fold the bar up or down as needed.

Power Tool Monitoring With The Smart Connector

INTEGRATION INTO STIHL CONNECTED. The power tool is compatible with the Smart Connector, meaning it can be integrated into the STIHL connected system. Once you have attached a Smart Connector to the power tool, after one-time commissioning it will record the power tool’s operating hours and transmit them to the STIHL connected App via Bluetooth. In addition to displaying the operational time, the app also provides an overview of all necessary maintenance, ensuring that you do not overlook important upkeep and that your power tool is always in a ready-to-use condition.
