TRIMMER TIPS
A WARNING: Debris such as sticks,
gravel or rocks, can be thrown
with sufficient force to cause per-
sonal injury or property damage.
Set the throttle control in the FAST posi-
tion. If the weeds or grass are tall and
thick, operate the trimmer at a slower
walking speed.
Frequently clean the underside of the trim-
mer to remove any grass build up. See the
Maintenance section for details.
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.

If the trimmer lines become too short, it will
take longer to complete the job. If the trim-
mer lines are worn to less than half their
original length, change to a new trimmer
line. "See How To Change The Trimmer
Line" in the Service And Adjustment sec-
tion.

a slope isdifficult to stand on, do not trim.
Do not trim on slopes when the ground is
slippery or wet. Trim across the face of a
slope, not up and down.
Trimmer head contact to concrete, asphalt
and harder services may create prema-
ture wear to the height guide (See
Figure 18).
