|---|---|
| 1 | Remove the housing by unscrewing the screws that hold it in place. |
| 2 | Rotate the trimmer head counterclockwise until it comes off. |
| 3 | Remove the old line by pulling it out of the holes in the head. |
| 4 | Thread the new line through the holes in the head and tie it off. |
| 5 | Reattach the trimmer head to the housing by screwing it back on. |
Removing the Old String
1. Unplug the weed eater from the power source.
2. Locate the trimmer head, which is the rotating part at the end of the shaft.
3. Turn the trimmer head counterclockwise to loosen it, and then pull it off the shaft.
4. The old string will be wrapped around the spool inside the trimmer head. Carefully unwrap the string from the spool, taking care not to damage the spool or the string.
| Tips for removing the old string: |
|---|
| **Use a pair of scissors to cut the string close to the spool.** This will make it easier to unwrap the string and prevent it from getting tangled. |
| **Hold the spool in one hand and use your other hand to gently pull the string away from the spool.** Avoid pulling too hard, as this could damage the string or the spool. |
| **If the string is particularly stubborn, you can use a small screwdriver to gently pry it away from the spool.** Be careful not to damage the spool or the string. |
5. Once the old string has been removed, discard it and replace it with new string.
Winding the New String
Once you have identified the direction of rotation for your weed eater, you can start winding the new string. Here’s a detailed guide on how to do it:
- Start by inserting an end of the new string into the hole in the center of the spool.
- Holding the other end of the string taut, wind it around the spool in the direction indicated by the arrow.
- Make sure to keep the string tightly wound, but not so tight that it binds or cuts itself.
- Continue winding the string until you reach the outer edge of the spool.
- Cut the excess string and insert the remaining end into the hole in the side of the spool, securing it in place.
| Tip for Winding the New String |
|---|
| To ensure even winding, wrap the string in overlapping layers, covering the previous layer by about half. |
| If the string starts to bunch up or tangle, stop winding and untangle it before continuing. |
| Once the string is wound, gently pull on it to make sure it is secure and not too loose. |
Adjusting the String Length
After inserting the new string, it’s crucial to adjust its length to ensure optimal performance and efficiency. Here’s how to do it step-by-step:
1. Pull the String Through the Spool
Insert the string into the designated slot on the spool and pull it through, ensuring it follows the groove or guide provided.
2. Secure the Loop
Form a small loop at the end of the string and hook it over the hook or pin on the trimmer head. This loop will hold the string in place.
3. Adjust the String Length
Begin extending the string by pulling it downwards. The ideal length for each string is around 6-8 inches (15-20 cm). Trim any excess string using a sharp pair of scissors.
4. Cut the String
Once the string reaches the desired length, cut it at an angle to prevent fraying. This angled cut creates a clean edge for a more efficient cutting performance.
5. Load the Second String
Repeat the above steps to load the second string into the remaining slot on the spool and guide it through the trimmer head.
6. Test and Adjust
Start the weed eater and allow the strings to fully extend. Observe the cutting performance and make any necessary adjustments to the string length. Ideally, the strings should be equal in length and extend just beyond the edge of the trimmer head guard.
| Recommended String Length | Trimmers With Auto-Feed | Trimmers Without Auto-Feed |
|---|---|---|
| 6-8 Inches (15-20 cm) | Not applicable | Adjust manually as per guide |
