smoke the first time it is started. It is burning
off the protective coating that is on the internal

shown in NO TAG. Debris can cause the engine to
overheat. Wipe the debris screen with a cloth or paper
towel.

or FAST position.

trimmer tips
• Set the throttle control in the FAST position. If the
weeds or grass are tall and thick, operate the trimmer
at a slower walking speed.
• Frequently clean the underside of the trimmer 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 trimmer 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 section.
• Do not trim on excessively steep slopes. If a slope
is difficult 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 premature wear to the height
guide.
