Understanding STIHL Weed Eater String Types

Before diving into the reloading process, it is essential to understand the different types of string used in STIHL weed eaters. The two main categories are round string and serrated string. Round string is the most common and is suitable for general trimming tasks. It comes in various diameters, typically ranging from 0.065 inches to 0.105 inches. Larger diameters are more durable but may not fit all trimmer heads. Serrated string, on the other hand, features a twisted or cord-like texture that provides extra cutting power, making it ideal for heavier vegetation. Some models also support specialty lines such as square or star-shaped string, which offer enhanced durability and cutting efficiency. Always consult your trimmer manual to confirm the recommended string type and diameter for your specific model.

Tools and Materials You Will Need

Reloading STIHL weed eater string does not require advanced tools, but having the right materials on hand will make the process smoother and faster. Here is a list of items you should gather before starting:

• Replacement string (compatible with your trimmer model)
• Scissors or a utility knife
• A clean cloth or paper towel
• Optional: Small flathead screwdriver
• Optional: String cutter or line winder tool

Using the correct replacement string is crucial for ensuring proper operation and preventing damage to your trimmer. Always verify the string diameter and length recommended by STIHL for your specific model.

Identifying Your STIHL Trimmer Head Type

STIHL offers several types of trimmer heads, each with a unique mechanism for feeding and replacing string. The most common types include bump feed, automatic feed, and fixed-line heads. Bump feed heads require you to manually tap the trimmer head on the ground to release more line. Automatic feed heads dispense line automatically as needed. Fixed-line heads use pre-cut lengths of string that must be manually replaced. To identify your head type, inspect the trimmer head closely. If there is a small hole or slot on the side, it is likely a bump feed head. If the head has a cap that can be twisted off, it may be an automatic feed model. Refer to your user manual for confirmation if you are unsure.

How to Remove Old String

Before installing new string, you must remove the old, worn-out line. Start by turning off your trimmer and disconnecting the spark plug wire to prevent accidental starting. Next, locate the string release mechanism on your trimmer head. For bump feed heads, this is usually a small tab or button on the side of the head. Press or slide this mechanism to release tension on the string. Once tension is released, pull the old string out of the spool. If the string is tangled or stuck, use a pair of scissors or pliers to carefully cut it free. After removing the old string, inspect the spool and inner components for debris or damage. Clean any dirt or grass clippings from the spool using a cloth or compressed air.

Step-by-Step Guide to Reloading String

Now that you have removed the old string, you are ready to install the new line. Follow these steps carefully to ensure proper installation:

1. Prepare the new string: Cut a length of replacement string that is appropriate for your trimmer head. Most bump feed heads require approximately 20 feet of string, while automatic feed models may need more. Refer to your manual for exact specifications.
2. Locate the starting hole: Find the small hole or notch in the center of the spool where the string begins. This is typically marked or visible on the spool.
3. Thread the string: Insert one end of the string into the starting hole and push it through until about 2 inches protrude from the other side.
4. Wind the string: Hold the spool steady with one hand and begin winding the string in the direction indicated by the arrows on the spool. Keep the string taut but do not over-tighten, as this can cause binding.
5. Secure the spool: Once all the string is wound, ensure the end is tucked neatly into the groove or slot on the spool to prevent unwinding.
6. Reinstall the spool: Place the spool back into the trimmer head, aligning it with the notches or grooves as shown in your manual. Secure it by twisting or snapping it into place.
7. Test the line feed: If your trimmer has a bump feed mechanism, gently tap the head on the ground to feed out a small amount of string. For automatic feed models, start the trimmer and allow it to dispense line automatically.

After completing these steps, your STIHL weed eater should be ready for use. Always test the trimmer in a safe area before beginning your trimming project.

Tips for Choosing the Right String

Selecting the correct replacement string is vital for optimal performance and longevity of your STIHL trimmer. Here are some key tips to help you choose the right option:

• Check the diameter: Using a string that is too thick can strain the motor and cause premature wear. Too thin, and it may break frequently.
• Consider the vegetation type: Heavy-duty applications such as thick grass or weeds may benefit from serrated or square-line string.
• Buy high-quality string: Investing in premium string reduces the frequency of replacements and minimizes the risk of tangles.
• Match the original: If possible, use the same type and size of string that came with your trimmer from the factory.

STIHL also offers genuine replacement parts and accessories, which are designed to meet the exact specifications of your tool. Using authentic STIHL string ensures compatibility and reliability.

Common Problems and Solutions

Even with careful attention to detail, issues can arise when reloading STIHL weed eater string. Here are some of the most frequently encountered problems and their solutions:

• String tangles easily: This is often caused by improper winding or using the wrong string type. Rewind the string carefully, following the direction indicated on the spool.
• Line does not feed properly: Check for blockages in the trimmer head or spool. Clean out any debris and ensure the spool is installed correctly.
• String breaks frequently: This may indicate that the string is too thin for the job or that the trimmer head is misaligned. Upgrade to a thicker or more durable string if necessary.
• Spool will not turn: Ensure the spool is seated properly and that all locking mechanisms are engaged. If the problem persists, consult a STIHL dealer for professional assistance.

Addressing these issues promptly can prevent further damage to your trimmer and extend its lifespan.

Best Practices for Maintenance

Regular maintenance of your STIHL weed eater goes beyond just reloading the string. Here are some best practices to keep your tool in top condition:

• Store properly: Keep your trimmer in a dry, sheltered location away from direct sunlight and moisture.
• Clean after use: Remove grass clippings and debris from the trimmer head and housing after each use.
• Inspect regularly: Check the string, spool, and trimmer head for signs of wear or damage before each use.
• Use the right string: Always use string that matches the manufacturer’s specifications for your model.
• Follow the manual: Adhere to the guidelines provided in your user manual for optimal performance and safety.

By incorporating these habits into your routine, you can maximize the efficiency and lifespan of your STIHL weed eater.

When to Replace vs. Refill

Deciding whether to replace or refill your STIHL weed eater string depends on several factors. If the string is simply running low or has minor wear, refilling is usually sufficient. However, if the string is severely frayed, tangled beyond repair, or if the spool itself is damaged, replacement is the better option. Additionally, if you frequently encounter the same issues despite refilling, it may be time to upgrade to a different string type or consult a professional. Regular inspection will help you determine the best course of action for your trimmer.

Safety Precautions

Working with power tools like STIHL weed eaters requires attention to safety. Before reloading the string, always follow these precautions:

• Turn off the engine: Ensure the trimmer is completely off and the spark plug wire is disconnected.
• Wear protective gear: Use gloves and safety glasses to protect your hands and eyes from debris.
• Work in a well-lit area: Adequate lighting helps you see small parts and avoid mistakes.
• Keep children and pets away: Maintain a safe distance for others while working with power tools.
• Follow instructions: Adhere to the manufacturer’s guidelines for your specific trimmer model.

These safety measures reduce the risk of injury and ensure a smooth reloading process.

Troubleshooting Tips

If you encounter difficulties while reloading your STIHL weed eater string, consider these troubleshooting tips:

• String won’t stay in the spool: Ensure the string is wound tightly and secured in the designated groove or slot.
• Trimmer head won’t rotate: Check for obstructions and verify that the spool is installed correctly.
• Line feeds unevenly: Adjust the tension or reposition the string on the spool for balanced feeding.
• Engine struggles under load: This may indicate that the string is too thick or the trimmer head is clogged with debris.

If problems persist after trying these solutions, contact a certified STIHL dealer for professional support.
