OPERATING THE TRIMMER/EDGER
	TRIMMER/EDGER MODEL ST250

Controlling trimmer head speed

The throttle trigger controls the speed at which the trimmer head turns. Squeeze the throttle trigger more firmly for faster cutting speed.

Use the lowest pressure required to cut the material. This helps to maximize the amount of cutting time per battery charge and reduces the number of charging operations required.

Advancing trimmer line

The trimmer line wears down as you use the trimmer/edger. Let out more trimmer line as needed.

With the motor running and the trimmer head turning, bump the trimmer head on the ground (Fig. 14). More trimmer line comes out of the spool, and excess trimmer line is cut off by the line cutting blade on the bottom of the guard.

If the trimmer line does not come out, the spool may be empty. Turn off the trimmer/edger and replace trimmer line as described in “Replacing trimmer line”.

Trimming

Trimming cuts grass and weeds that are close to walls, fences, and other areas too small to reach with a lawn mower, down to a manageable height but not down to soil level.

Assume proper grip and stance, then start the trimmer. Squeeze the throttle trigger until the trimmer head achieves the minimum speed necessary to cut the grass or weeds.

Angle the trimmer head slightly toward the direction of the cut (Fig. 15).

5–10°

Push the trimmer head slowly from the side into the grass or weeds to be cut, and move the trimmer head back and forth so that the end of the trimmer line contacts the material to be cut.

Do not allow the trimmer line to touch the ground.
