Using your Yard Machine Y28 weed trimmer often puts your string cutters in contact with fences, rocks and other hard objects that can wear the cord down or break it off. Eventually, you'll need to restring the trimmer yourself--a quick process that is more economical than buying an entire replacement spool. At a home improvement or hardware store, purchase .080-inch diameter monofilament replacement string.

Disconnect the spark plug wire so that Yard Machine Y28 trimmer will have no way of accidentally starting. Position the trimmer on the ground to gain access to the power head.

Remove the spool retainer on the power head by twisting it in a counterclockwise direction. Take the spool assembly and its accompanying spring from the string head. Remove any remaining string cord and discard it.

Measure and cut two 9-foot pieces of monofilament replacement string. Insert one end of one piece of the string into the anchor hole.

Repeat this process with the second length of string on the lower part of the spool.

Using a stiff brush and damp rag, clean debris and built-up grass from the power head.

Replace The Line In A Ryobi Trimmer

Replacing the line in a Ryobi string trimmer is an inexpensive job that can be done relatively quickly with just a few tools. Most models need 0.80-inch diameter monofilament replacement line, which is readily available at most garden centers and home improvement retailers. Models powered by electricity should be disconnected from the power source. Lay the trimmer on a flat spot in your yard, driveway or garage so you can work on the power head. Remove the spool cap and bump knob by unscrewing the cap. Throw away any string that might remain on the inner spool. Position the end of the trimmer cord in the inner slot of the inner spool and start winding the monofilament line counterclockwise. The line should be kept tight and even on the spool. Stop winding when you have 6 to 8 inches of line left. Reconnect the sparkplug wire or plug the unit back into the electrical outlet.
