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.

Additional features

STIHL ErgoStart (E):

Easy starting with less effort due to an additional spring between the crankshaft and the rope rotor. A smooth pull on the starter rope tensions the spring against the compression resistance of the engine. The jerks are not transmitted to the rope. The spring automatically transmits the stored energy to the crankshaft, causing it to turn and ensuring reliable starting of the engine.

Shoulder strap / carrying system:

Using a STIHL shoulder strap or carrying harness with soft padding makes work more comfortable, particularly during lengthy jobs.
