Reduced-emission engine technology
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.
Manual fuel pump (Purger)
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.
Catalytic converter
Considerably reduces the quantity of harmful particles in the exhaust gas.STIHL ErgoStart (E)Zoom
STIHL ErgoStart (E)
A genuine advance in easy starting. STIHL ErgoStart (E) cuts the effort required to start the tool by half, while the starter cord can be pulled at just one third of the normal force. All it takes is 2 fingers and a gentle pull action.
One handled control with soft grip area
For a secure and comfortable grip. The integrated anti-static system counters electrostatic charging.
Throttle lock with built in stop switch
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.
Low noise sound damper
The BG 66 C-E with built-in sound damper is built for use in noise-sensitive areas. The measured noise reduction for the human ear is up to 35% compared to the previous model.** Despite the relatively low noise emission, the BG 66 C-E is a strong, reliable helper with high performance. ** Measured according to EN-IS022868.
Anti-vibration system
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

HD2 Filter
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.
