STIHL injection
HIGH PERFORMANCE IN COMPACT DESIGN. The electronic fuel injection control unit continuously calculates the correct fuel supply and the ideal ignition time, and injection is performed directly into the crankcase via the injection valve. Additionally, sensors measure air pressure and internal and external temperature, and pass information on to the control unit. This can use the identified values to determine the optimum fuel quantity and ignition timing. This means that your tool offers more power from a similar weight and installation space compared to engines without injection.
STIHL 2-MIX engine
HIGHLY POWER-EFFICIENT. With the STIHL 2-MIX engine, you can reduce exhaust emissions and fuel consumption, and therefore operating costs. This 2-stroke engine is low-maintenance and uses fuel efficiently even at high power levels. Use a mixture of petrol and engine oil as fuel. The STIHL 2-MIX engine complies with the strict EU Stage V emissions directive.
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.
Manual decompression
EFFORTLESS START-UP. The decompression valve makes it easier to start your tool. When starting, you can allow some of the compressed mixture to escape from the cylinder by opening the valve. This protects the start-up system and reduces the amount of force required on the starter cord.
STIHL electronic water control (A)
The electronic water control system can be operated via simple buttons while the engine is running. The water then switches on and off during cutting automatially, depending on engine speed. The water volume can be regulated by simply pressing the plus / minus buttons, ensuring optimum dust suppression at the touch of a button.
Pre-separation air filtration system
STIHL long-life air filtration systems with pre-separation achieve perceptibly longer filter life compared with conventional filter systems. Air drawn in is swirled. The larger, heavier particles are ejected. The pre-cleaned air is routed to the air filter via the pre-separator duct
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.
Ergonomic handle
FOR PRECISE GUIDANCE. With the ergonomic handle, you can keep a firm grip on your tool and carry out cuts precisely, even when dealing with very hard stone. The curved handle offers you an optimised grip position and the highest level of comfort when working.
Semi-automatic drive belt tensioning
Light, consistent re-tensioning increases the service life of the belts and shaft bearings
