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.

AUTOMATIC DECOMPRESSION

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.

STIHL 4-MIX® ENGINE

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. That’s why it’s 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.

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.

MANUAL FUEL PUMP

FOR FEWER STARTING STROKES. The manual fuel pump reduces the number of strokes required to start the 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.

STIHL ANTI-VIBRATION SYSTEM

FOR MORE PLEASANT WORK. Vibrations can occur when you put your 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 tool is more comfortable to hold and your work is much less tiring.

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.
