After hitting hard objects such as bricks, rocks and tough brush, the cutting line on a Diatop brush cutter can wear down until it needs to be reloaded. Restringing the line on this Honda-manufactured trimmer can be done in a few minutes with just a few tools. This unit requires 0.095-inch diameter monofilament replacement line, which is available at most home improvement retailers and hardware stores.
Detach the sparkplug wire so the unit will not operate while you are working on the power head. Place the unit on a flat surface and remove the cover from the power head housing by pressing on the two tabs on opposite sides of the outer hub.
Remove the inner spool from the outer hub. Measure and cut 16 feet of 0.095-inch diameter monofilament replacement line. Fold the line nearly in half, leaving one side about 3 inches longer than the other.
Insert the folded side of the trimmer line into the slot in the middle of the inner spool. Begin winding the trimmer line in the direction of the arrows located on the back of the inner spool. One of the lines should be wound in the upper gutter, while the other should be wound in the lower gutter.
Stop winding with about 6 inches of line left on the longest end of the trimmer line. Secure the line in the holding notches located on the inner spool.
Place the inner spool in the outer hub. Pull the trimmer line into the eyelets in the outer hub. Replace the cover on the outer hub and lock the tabs in place. Replace the sparkplug wire to restore power to the unit.
While the unit is disassembled, wipe away debris and other build-up from the power head with a damp cloth.
