Understanding the Stihl String Trimmer
Before we dive into the replacement process, it’s important to understand the basics of your Stihl string trimmer. This powerful tool is designed to make trimming and edging tasks a breeze. The string, also known as the cutting line, is the heart of the trimmer. When it wears out or breaks, it’s time for a replacement.
Here are a few things you should know about your Stihl string trimmer:
- Model Variations: Stihl offers a wide range of models, each with its own unique features. Make sure you know which model you have to ensure you get the right replacement parts.
- String Types: Stihl trimmers typically use either single-line or double-line heads. The type of string you need will depend on your specific model.
- Replacement Frequency: Depending on how often you use your trimmer, you may need to replace the string several times a year.
Why Replace the String?
Replacing the string on your Stihl string trimmer is crucial for maintaining its performance. Over time, the string can wear down, fray, or break completely. When this happens, your trimmer won’t cut as effectively, leading to uneven edges and wasted effort.
Here are some signs that it’s time to replace the string:
- The string is frayed or broken.
- Your trimmer is struggling to cut through grass or weeds.
- You notice uneven trimming patterns.
By replacing the string regularly, you ensure your Stihl string trimmer remains in top condition. Plus, it’s a cost-effective way to extend the life of your tool.
Tools You’ll Need
Before you begin, make sure you have all the necessary tools and materials. Here’s a quick checklist:
- A new spool of string (compatible with your Stihl model).
- A pair of pliers (optional, but helpful).
- A small screwdriver (if your trimmer head requires disassembly).
- A pair of gloves (to protect your hands).
Having these tools on hand will make the process smoother and more efficient. Trust me, you don’t want to be halfway through the job and realize you’re missing something important.
Step-by-Step Guide to Replace the String
Now that you’re prepared, let’s get into the nitty-gritty of replacing the string on your Stihl string trimmer. Follow these steps carefully to ensure a successful replacement:
Step 1: Turn Off the Trimmer
Safety first! Always turn off your Stihl string trimmer and let it cool down before starting any maintenance work. This will prevent any accidental starts and keep you safe while you work.
Step 2: Remove the Trimmer Head
Most Stihl string trimmers have a head that can be easily removed by unscrewing it. Some models may require you to use a small screwdriver to detach the head. Once the head is off, you’ll have access to the spool inside.
Step 3: Take Out the Old Spool
Remove the old spool from the head. If the string is broken or tangled, you may need to use pliers to carefully pull it out. Discard the old spool and get ready for the new one.
Step 4: Load the New Spool
Take your new spool of string and feed the string through the designated hole in the spool. Make sure the string is wound in the correct direction, which is usually indicated by an arrow on the spool. Wind the string tightly, leaving about 6 inches of excess string sticking out.
Step 5: Reassemble the Head
Once the spool is loaded, place it back into the trimmer head. Secure the head by screwing it back on tightly. Make sure everything is snug to prevent any movement during operation.
Step 6: Test the Trimmer
Before you start trimming, test the trimmer to ensure the new string is working properly. Turn on the trimmer and let it run for a few seconds. If the string feeds out smoothly and cuts effectively, you’re good to go!
Tips for Maintaining Your Stihl String Trimmer
Maintaining your Stihl string trimmer goes beyond just replacing the string. Here are a few tips to keep your tool in top condition:
- Regularly clean the trimmer head and spool to prevent debris buildup.
- Check the air filter and fuel lines for any blockages or damage.
- Store your trimmer in a dry, secure location when not in use.
- Follow the manufacturer’s recommendations for maintenance and replacement schedules.
By following these tips, you’ll ensure your Stihl string trimmer remains a reliable tool for years to come.
Common Issues and Troubleshooting

Issue 1: String Won’t Feed Out
