Line Crowded Into

Work Area

S The line will easily remove grass and

weedsfromaroundwalls,fences,treesand

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 to increase line life and decrease

head wear, especially:

S During light duty cutting.

S Near objects around which the line can-

wrap such as small posts, trees or fence

wire .

a good clean job.

unwanted vegetation. Hold the bottom of the

trimmer head about 80 mm above the ground

and at an angle. Allow the tip of the line to strike

the ground around trees, posts, monuments,

etc. This technique increases line wear .

in places conventional lawn mowers cannot

reach. In the mowing position, keep the line

parallel to the ground. Avoid pressing the

head into the ground as this can scalp the

ground and damage the tool.
