► Place the unit securely on the ground and
make sure that bystanders are well clear of
the nozzle outlet.
► Make sure you have a firm footing: Hold the
unit with your left hand on the housing and put
one foot against the base plate to prevent it
slipping.
► Hold the starter grip with your right hand.
► Pull the starter grip slowly until you 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. Guide it
slowly back into the housing so that the starter
rope can rewind properly.

cranking until the engine runs.
