Cranking
Place the unit on the ground: It must
N
rest securely on the engine support
and the deflector.
If fitted: Remove the transport guard
N

To reduce the risk of accidents, check
that the cutting attachment is not
touching the ground of any other
obstacles.
Make sure you have a firm footing,
N
either standing, stooping or
kneeling.
Hold the unit firmly on the ground
N
with your left hand and press down
– do not touch the throttle trigger or
lockout lever – your thumb should
be under the fan housing.
NOTICE
Do not stand or kneel on the drive tube.
Hold the starter grip with your right
N
hand.
Pull the starter grip slowly until you
N
feel it engage and then give it a brisk
strong pull.
NOTICE
Do not pull out the starter rope all the
way – it might otherwise break.
Do not let the starter grip snap back.
N
Guide it slowly back into the housing
so that the starter rope can rewind
properly.
Continue cranking until the engine
N
runs.
