convert to edging mode

WARNING: Disconnect the plug from the power source before making any adjustments. The trimmer can be used in trimming mode or edging mode to trim overhanging grass along lawn edges and flower beds.

WARNING: When being used as an Edger, stones, pieces of metal and other objects can be thrown out at high speed by the line. The trimmer and guard are designed to reduce the danger. However, MAKE SURE that other persons and pets are at least 100 feet (30m) away.

• To operate as a maintenance edger, turn the collar (5) as shown in figure G.

• Hold the metal shaft and rotate the lower housing 180° as shown in figure J.

• Turn the collar back until tight.

Note: The metal shaft and housing will only rotate in one direction.

• To return to the trimming position, loosen the lock collar and rotate the lower housing back 180° and retightening the collar.

Edging

Your string trimmer is equipped with Smart Edge Technology that will automatically shift to a more efficient speed when in edging mode for better control.

Optimum cutting results are achieved on edges deeper than 2 inches (50 mm).

• Do not use this trimmer to create trenches.

• Using the edging wheel (7), guide the trimmer as shown in figure K.

• Position the edging wheel on the edge of the sidewalk or abrasive surface so the cutting line is over the grass or dirt area to be edged.

Note: The Auto Feed System may not operate correctly if wheeled edge guide is not used.

Note: You will experience faster than normal cutting line wear if the edging wheel is positioned too far from the edge with the cutting line positioned over the sidewalk or abrasive surface.

• To make a closer cut, slightly tilt the trimmer.

• Return to the trimming postion by loosening the lock collar and rotating the lower housing back 180°. The tool will lock in the trimmer position.

Cutting Line / LINE FEEDING

Your trimmer uses .065 inch (1.65 mm) diameter, ROUND nylon line. During use, the tips of the nylon lines will become frayed and worn and the special self feeding spool will automatically feed and trim a fresh length of line. Cutting line will wear faster and require more feeding if the cutting or edging is done along sidewalks or other abrasive surfaces or heavier weeds are being cut. The advanced automatic line feeding mechanism senses when more cutting line is needed and feeds and trims the correct length of line whenever it’s required. Do not bump trimmer on ground in attempt to feed line or for any other purposes.
