How to Install New Line on Your String Trimmer

What You'll Need
Trimmer line

A string trimmer is an extremely important garden tool that can help you keep your grassy areas neat and clean. However, strings can often break and new lines may need to be inserted. The line is usually wound tightly on a spool and as you use the line to cut the grass, it continues to wear out till it completely breaks off. A new line is usually fed into the spool, and the spool releases the line to trim the grass. In some cases, the spool itself may need to be replaced completely. Here’s how you can install a new line on your string trimmer.

Step 1 – Remove the Spool

Turn off the lawn trimmer or remove the connection to make sure there is no power running through it. Locate the spool retainer right at the bottom of the cutting head. Now turn the cutting head either clockwise or counter clockwise. This can be done by pressing a release button that allows the clip to loosen up and release the spool. Different models have different mechanisms, and if you are unable to understand the mechanism on your trimmer, use the manual to understand how to remove the spool.

Step 2 – Empty the Spool

Once you are able to release the retainer, remove it by pulling the spool away from the head. There may be a spring on the spool. Sometimes, the spring may be present on the cutting head. Try to keep the spring in place. Remove the old lines from the spool as they may be damaged. If the old lines are used up, you simply have to put in a new one.

Step 3 – Insert a New Line

Once the spool has been emptied, cut the trimmer line to a length of 9 feet. Sometimes, the trimmer may require two lines. If that is the case, cut two 9-foot long lines. Let the spring face up and hold the spool. There is a small anchor hole into which you can insert the end of a line. This anchor hole is usually located in the side of the spool. For double lines, first install the line that goes into the upper area, before coming to the second line. The spool will have an arrow drawn on it that indicates the direction in which the line should be wound. Wind the entire length of the line into the spool until only about 6 inches of line is remaining. Locate the retention slots. These are usually located in the upper flange of the spool. Press the remaining line into the retention slots. If there are two lines, you can simply insert the other line into the anchor hole located in the lower area. Again, wind the second line until only 6 inches remain. Insert the second line into the other retention slot.

Step 4 – Check the New Line

The new line has been installed in the spool. To check the same, simply turn on the trimmer and observe whether the line is trimming in the proper manner. If there is a snag in the line, you may have to remove the spool and wind the line once again, tightly.
