1) operating state
2-stroke engine with stratified charge: During the flushing process a fuel-free layer of air is created between the burned charge in the combustion chamber and the fresh charge in the crankcase. This cushion reduces the amount of fuel lost in flushing discharge during the charge cycle. The result? More power with a lower weight, up to 20% lower fuel consumption than regular 2-stroke engines and significantly reduced exhaust emissions.
Intense vibration at the handles of power tools can lead to longer-term effects of blood vessels in the hands and arms. STIHL have therefore developed an effective anti-vibration system where by the oscillations from the machines engine are dampened which significantly reduces vibrations at the handles allowing for more comfortable and safer operation.
Easy starting with less effort due to an additional spring between the crankshaft and the rope rotor. A smooth pull on the starter rope tensions the spring against the compression resistance of the engine. The jerks are not transmitted to the rope. The spring automatically transmits the stored energy to the crankshaft, causing it to turn and ensuring reliable starting of the engine.
The running machine switches off reliably after a brief press of a button. Once the machine is at a standstill, the ignition activates again automatically. Thus the ignition is always ready for starting.
For secure and comfortable grip. With integrated anti-static system.
This carrying system make the job easier and more comfortable, especially for longer working periods. It is part of every STIHL model.
A small fuel pump delivers fuel to the carburettor at the touch of a button. This reduces the number of starting strokes required from a cold start.
