STIHL ElastoStart reduces the shock caused by the compression of the engine during starting. The compression shock is taken away from the user's joints and muscles through a spring or rubber element in the starter handle.

2-stroke engine with stratified charge. A fuel-free layer of air is created between the burned charge in the combustion chamber and the fresh charge in the crankcase, reducing the amount of fuel lost during the charge cycle. This results in more power with a lower weight, up to 20% lower fuel consumption than regular 2-stroke engines and significantly reduced exhaust emissions.

The HD2 filter, made from polyethylene filter material, has pores that are up to 70% finer than those of fleexe and polyamide filters and therefore eliminates even the finest dust. In addition, it repels oil and water and is therefore very easy to clean. The PET filter cartridge can be removed and inserted without tools.

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.

A small fuel pump delivers fuel to the carburettor at the touch of a button. This reduces the number of starting strokes required following extended breaks in operations.

The running machine switches off immediately after a brief press of a button. Once the machine is at a standstill, the ignition activates again automatically, meaning it is always ready to start.
