Choosing the Right String

It is very important that you choose the right string for your single liner weed eater. When you unknowingly purchase a longer or a thicker string, it won’t go through the hole and it’ll be a complete waste of your time and money. To avoid this situation, always refer the product manual and note down the exact string size for the model you own.

If you don’t have it with you, no worries! Go to the manufacturer website and you’ll find the exact string size you need for your model. Calling the customer care of the manufacturer is also a good idea.

After selecting the right string size, try to cut the string to the appropriate size for that model. It can be from 10 to 25 inches long. If you aren’t sure the length you need, always cut a little extra. This is simply because it is very easy to trim the string to the exact size rather than fitting it fully into the weed eater, realizing that it is small and removing it from the spool.

The starter hole will be in the middle of the spool. After you find it, insert the tip of the string into the hole. When you complete that, check throughout the spool for the imprint of arrows.

Start to rap the string in the direction of the arrow. But sometimes, you’ll see that the arrows are given by the manufacturer at the bottom of the cap. And those arrows may worn  down after a certain amount of usage.

If this is the case, just try to rap the string in an anti-clockwise method. If you rap it in a clockwise method, there is a high-possibility that the string may come off right after you start the weed eater engine.

You definitely don’t want that to happen. Right? and in the end, it’ll be an extra work for you to fix the string again. Try rapping the string in a neat line and after you notice that there are only 5 to 6 lines remaining, snap it into the retainer cap so that it holds the string in place.
