Operating Techniques
1. Before edging, water the area to soften the ground to make edging
easier.
2 Before edging, check the area and remove all obstacles and ob-
jects that could be thrown.
3. Plan to edge regularly to make it easier to keep a neat edge and to
avoid having to make more than one pass.
NOTE
Blade depth may have to be adjusted due to differences in height
between the hard surface and the top of the grass.
