: Set the choke knob (4):
To g if engine is cold.
To e if engine is warm.
(also use this setting if the engine
has been running but is still cold)
: Press the fuel pump bulb (5) at least
five times.
: Place the machine on the ground so
that it is secure.
: Put your right foot in the handle
frame and press down, left hand on
the handle frame.
: 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 starter rope to full
length – it might break.
: Do not let the starter grip snap back
– guide it back into the housing so
that the starter rope can rewind
properly.
: Continue cranking until the engine
runs.
When the engine begins to fire:
: Turn the choke knob to e and
continue cranking.
As soon as the engine runs:
: Blip the throttle trigger (2) –
the slide control (3) moves to the run
position # and the engine settles
down to idle speed.
.
Since the auger brake is still
engaged, the engine must be
returned to idle speed immediately
– or the clutch might otherwise be
damaged.
