Cranking
N Place the unit on the ground so that
it is secure.
N Put your right foot in the handle
frame and press down.
N Left hand on the handle frame.
N Pull the starter grip slowly with your
right hand until you feel it engage
and then give it a brisk strong pull.
Do not pull out the starter rope all
the way – it might otherwise
break.
N Do not let the starter grip snap back.
Guide it slowly back into the housing
so that the starter rope can rewind
properly.
N Continue cranking.
When the engine begins to fire:
N Turn the choke knob to e.
N Continue cranking until the engine
runs.
As soon as the engine runs
N Blip the throttle trigger (2) – the slide
control (3) moves to the run
position F and the engine settles
down to idling speed.
Since the auger brake is still
engaged, the engine must be
returned to idling speed
immediately – or the clutch might
otherwise be damaged.
