Always use two hands while operating the trimmer. Use one hand on the main
handle to operate the switches and the other on the assist handle.
Use a semi-circular sweeping motion, with the trimmer head tilted slightly
downward where the trimmer line is cutting the grass.
Move the trimmer from right to left, feeding it into the uncut grass on the left side.
This motion will cause the trimmer to throw the cut grass away from the operator,
reducing the amount that is thrown toward the operator.
Maintain a consistent motion and speed when moving the trimmer through the
grass. This will provide a more even cut.
Hold the trimmer about 3" (7.6 cm) above the ground to avoid "scalping" and to
prevent premature wear on the line and the spool cover (Fig. 23).
If the grass it taller than 6" (15.2 cm), cut the grass in stages to maintain motor
speed and to prolong the battery life.

If the cutting circle is getting too small, the trimmer line may be either jammed on
the spool or has run out. Manually advance the line as outlined in Fig. 16. If that
fails, see "CORRECTING A JAMMED OR SHORT TRIMMER LINE" below.
When finished trimming, clean the underside of the guard and the spool. Advance
the line as outlined in Fig. 16 to ensure the line is the correct length for the next
trimming.
CORRECTING A JAMMED OR SHORT TRIMMER LINE
Under certain conditions, the trimmer line may become jammed or too short. In
either case, the line may fail to advance properly. If this happens, correct this
situation as follows:
