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 pulls required following extended breaks in operations.

HD2-Filter - The HD2 filter, made from polyethylene filter material, has pores that are up to 70% finer than those of fleece 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.

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.

One handle control with soft grip area - For a secure and comfortable grip.

Anti-vibration system - Intense vibration at the handles of power tools can lead to long-term effects on blood vessels in the hands and arms. STIHL has therefore developed an effective anti-vibration system whereby the oscillations from the machine's engine are dampened which significantly reduces vibrations at the handles.

Integrated shoulder strap for vacuum bag - The integrated shoulder strap makes vacuuming for long periods of time less tiring. Allowing for much more movement whilst helping to support the weight of the collection bag.

1) Without fuel in the vacuum operation
2) K-factor according to DIR 2006/42/EC = 2.5 dB (A)
3) K-factor according to DIR 2006/42/EC = 2m / s ²
