When you pull the starter grip, don't wrap the starter rope
around your hands. Do not allow the grip to snap back, but
guide the starter rope slowly back to permit the rope to
rewind properly. Failure to follow this probedure may result
in injury to hand or fingers and may damage the starter
mechanism.
