Standard equipment:

Modern, convenient and very easy to start. Ideal for around-the-garden trimming tasks.

Reduced-emission engine technology :

CLICK HERE TO ENLARGE

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.

running machine then switches off after a brief press of the stop button. Once the machine 
is at a standstill, the ignition activates again automatically. Thus the ignition is always ready
 for starting.
