There are three common ways for restringing, which all start with the same two steps.
The first is making sure the device is turned off. After that, you need to prepare the line. Always make sure the length, as well as the width of the line, coincide with the device in question.
With a single-line trimmer, you then need to remove the retaining cap. This component is usually found on the trimmer head.
Next, look for a starter hole on the spool. Once found, insert the line and start to wind the spool. During this process, follow the direction of the arrows. As well make sure that you maintain straight rows for the line as you wind it up.
This will prevent the machine from jamming up in the future. You then line up part of the line with the slot that leads outside the trimmer head. This is followed by replacing the spool and the cap.
You can test out the line by tugging at it. By doing this, you ensure that it feeds smoothly. The same process can be repeated for a double line trimmer.
Speed-feed trimmers are the easiest to restring. Put the string through one of the two eyelets provided on the trimmer head. If you push it in far enough, it should come out of the eyelet on the opposite end.
Make sure that both ends are even in length. Next, you rotate the head until the string left exposed is of a reasonable size. Five to six inches is often recommended.
