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.
-
Simplified starting system
Simply set the choke, pump the fuel primer, pull the starter cord and away you go! The 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.
