Advancing Trimmer Line

Replacing Trimmer/Edger Line

To reduce excessive line wear and improve trimming performance, follow the steps below to trim grass and weeds.

1.Remove any string, wire, or other ma- terials that could become entangled in the trimmer/edger from the trim- ming area.

2.Hold trimmer/edger using both front and rear handles (see Figure 4-11).

3.Slowly sweep the trimmer/edger from side to side or front to back.

4.Do not force the trimmer/edger. Al- low only the tip of the trimmer/edger line to cut the grass or weeds.

5.If grass or weeds are tall, cut them in several increments, starting from the top and working to the bottom.

WARNING: Blade is sharp. To prevent serious injury, do not touch blade.

To advance new trimmer/edger line,tap the line advance button on the ground while the trimmer/edger is running (see Figure 4-12). The blade attached to the cutting guard will cut the line to the proper length.

Follow the precautions below to ensure top line performance.

•Do not hold the line advance button on the ground. This will allow trim- mer/edger line to constantly feed oﬀ the spool.

•Tap the line advance button only once to advance line. If more line is needed, wait a few seconds and tap again.

•Be sure to advance the line as it wears down. If you wait too long to advance new line, the existing line will wear down too short and can retract into the spool. If this happens, remove the spool and reroute the line out of the spool. Reinstall the spool to the trim- mer/edger head.

WARNING: To prevent serious personal injury, never use metal- reinforced line, wire, or rope, etc. These can break oﬀ and become a dangerous projectile.

CAUTION: Use of line other than speciﬁed could cause per- sonal injury or product failure.

For replacement line,use a nylon monoﬁla- ment line of 0.065 inch in diameter. You can purchase replacement line at most lawn and garden stores.
