4. Loosen blade adjustment knob and adjust the blade’s depth
of cut to produce a fine cut between sidewalk and grass
using a minimum blade depth, usually with about 13 mm
(1/2 in.) of the blade into the ground. Tighten adjustment
knob.
5. Before edging, plan your direction of travel so that the unit
will always be on your right side and so that you walk on a
hard surface whenever possible.
6. Hold edger as shown.
7. When starting to work, run the engine at full throttle, and
lower the blade gently into the ground. Travel around
perimeter of bed, allowing the Redefiner to improve bed's
edge.
Use the blade location slot in the top of the debris shield as a guide
to align the blade with the cut during edging.
8. Do not force the blade. Move only as quickly as the blade
will allow.
