OPERATION
ADVANCING LINE
NOTE: The trimmer is equipped with an auto-feed head.
Do not bump the head or try to advance the line. This will damage the
trimmer and void the warranty.
1. With the trimmer running, release the on/off switch.
2. Wait two seconds, and press the on/off switch.
NOTE: The auto feed function works during the starting and stopping of the
trimmer. The line will extend approximately 3/16" with each stop and start of
the on/off switch WHILE NOT TRIMMING until the line reaches the length of
the grass deflector blade.
3. It may take up to 10 complete starts and stops to advance the line.
NOTE: After each use, clean the trimmer head with a damp cloth to remove
dirt and grime.
EDGING

The best method of edging is performed with the upper handle and assist handle rotated 180°.
1. Unplug the grass trimmer.
2. Press the rotational lock button and rotate the upper handle clockwise (Fig. 13).
3. Release button when the upper handle has been rotated 180° to the edging position.
4. Rotate assist handle 180° and snap onto index channel (Fig. 13).
5. Hold the trimmer with both hands for edging sidewalks and walkways (Fig. 14).
