Features

RESTART WORK QUICKLY. With the stop button, you can switch off your power 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.

EFFORTLESS STARTING. Automatic decompression makes it easier to start the engine. This is because the system automatically opens the intake valve when the engine is started; the opening time of the valve is extended, and as a result the compression pressure is reduced. This significantly reduces the force required on the starter cord.

FOR FEWER STARTING STROKES. The manual fuel pump reduces the number of strokes required to start the power tool, making the start-up process quicker and easier This is particularly helpful after longer breaks in operation. To use it, actuate the pump several times before starting. This will ensure that there is enough petrol in the carburettor when starting.

FOR FANTASTIC ENGINE POWER WITH LOW MAINTENANCE. The STIHL 4-MIX engine is a four-stroke engine that does not require any oil circuit components, thanks to refuelling with an oil and gasoline mix. Thats why its more compact, more lightweight, and requires less maintenance than conventional four-stroke engines, while at the same time being powerful and offering a comfortable sound pattern. STIHL 4-MIX engines comply with the European Stage V emissions directive.

FOR MORE PLEASANT WORK. Vibrations can occur when you put your power tools through their paces, and these are particularly noticeable in the grip area. The buffer and spring elements of the STIHL anti-vibration system reduce the transmission of engine vibrations to the handle area and therefore to your body. The result is that your power tool is more comfortable to hold and your work is much less tiring.
