Emergency OFF switch (Australia)

The emergency OFF switch

is located next to the throttle grip. Primarily

designed as safety or emergency OFF switch, it should normally not be in its
activated state.

In this position, the ignition circuit is shorted; if the engine is running,  
it will stall immediately, if it is at standstill, it will not start.

In this position, the ignition circuit is enabled; the engine should start.
