S The line will e asily remove grass and weeds
from around walls, fences, trees and flower
beds, but it also can cut the tender bark of
trees or shrubs and scar fences.
S For trimming or scalping, use less than full
throttle toincreaseline lifeand decreasehead
wear, especially:

wrap such as small posts, trees or fence
wire.
