bones, toys, and other foreign objects which could
be tripped over or picked up and thrown by the
string trimmer mower in any direction which could
cause serious personal injuryto the operator or any
others allowed inthe area. Plan your trimming
pattern to avoid discharge of material toward
building, walls, roads, sidewalks, bystanders and

thrown object injury,keep children, bystanders, and
helpers at least 75 feet from the string trimmer
mower while it is in operation. Stop the string
