Grip the turf edger's handle allowing the waist bar to rest against your waist.
Guide the turf edger with your hip rested squarely against the waist bar, noting how small movements in your hip translate into the edger rotor moving to different angles.
Turn on the turf edger.
Test the turf edger on a relatively hidden part of your lawn, practicing keeping it at a 20- to 25-degree angle.
Practice trimming to the proper depth of 1/2 to 1 inch. If you have problems visually eying the depth, cut a gap in the lawn, stick your finger into the gap and memorize the depth of about one knuckle.
Trim around stones and steps, keeping the edger at a 20-degree angle and the depth to about 1 inch.
