6.13 Trimming tips continued.
6.13.1 Set the throttle control in the FAST position. The faster the engine runs, the faster
the trimmer head will rotate. If the weeds or grass are tall and thick, operate the trimmer
at a slower waking speed.
6.13.2 Frequently clean the trimmer to remove any grass build up. See the Maintemnce
section for details.
6.13.3 For best results and longer lasting line use the ends of the line to do the cutting.
This is easily done by moving slowly through very thick or heavy weeds.
6.13.4 If the trimmer lines become too short, it will take longer to complete the job. If the
trimmer lines are worn to less than half their original length, change the trimmer line, See
"How to replace the trimmer line in the maintenance section.
6.13.5 DO NOT trim on excessively steep slopes. If a slope is difficult to stand on DO NOT
trim it.
