Trimmer Line Replacement: Buyer’s Guide

Trimmer lines may look simple, but changing them can turn into a challenging process. There are several rules you have to follow if you want to know how to change the trimmer line. Keep in mind you will have to order the trimmer line in advance.

With the wrong line, the whole instrument will not work. If you can’t find these measurements in the instructions to your trimmer, you can look for the model’s requirements online.

If you don’t want to lose your fingers while changing the weed eater line, make sure that the engine is off. It also must be cooled. Don’t simply press the button, it must be cold and far from the power source.

Step 4. Remove the rests of the old line and insert a new one

Here is the time to teach you how to put line in a weedeater. You have to insert the tip of the new trimmer line in the hole you see inside the spool. Now wind it in the directions usually marked by arrows. Make strong and neat moves, and don’t rush to avoid the jams. When you see 6 or 5 inches remain to the end, you have to stop and snap it to the retainer on the spool.
