Restringing a Stihl weed eater is a relatively simple task that can be completed in just a few minutes with the right tools and materials. However, if you’re not familiar with the process, it can be easy to make a mistake that could damage your weed eater or cause it to malfunction. In this article, we’ll provide you with step-by-step instructions on how to restring your Stihl weed eater safely and effectively, so you can get back to tackling your yard work in no time.
Before you begin, you’ll need to gather a few tools and materials. You’ll need a new trimmer line, a pair of safety glasses, a pair of work gloves, and a screwdriver or Allen wrench. You may also want to have a pair of pliers on hand to help you cut the trimmer line to the correct length. Once you have your tools and materials gathered, you can begin the restringing process.
The first step is to remove the trimmer head from the weed eater. To do this, simply unscrew the bolt or nut that holds the trimmer head in place. Once the trimmer head is removed, you can remove the old trimmer line. To do this, simply pull the trimmer line out of the trimmer head. Be careful not to damage the trimmer head or the trimmer line while you’re doing this. Once the old trimmer line is removed, you can begin winding the new trimmer line onto the trimmer head.
Safety First: Preparing for Restringing
Before embarking on restringing your Stihl weed eater, it’s imperative to prioritize safety. This involves carefully reviewing the operator’s manual and adhering to all safety guidelines. The following are key steps to ensure a safe and successful restringing process:
-
Disconnect the Spark Plug:
Locate the spark plug and carefully remove the spark plug wire. This crucial step prevents any accidental starts of the engine while restringing.
-
Wear Appropriate Gear:
Don gloves, safety glasses, and a face shield to protect yourself from sharp line ends and flying debris during restringing.
-
Secure the Trimmer:
Place the weed eater securely on a stable surface or workbench to prevent it from toppling over while you’re restringing.
-
Identify the Type of Line:
Determine the correct line diameter and length for your specific Stihl weed eater model. Refer to the operator’s manual or consult with a qualified technician for guidance.
-
Gather Necessary Tools:
Assemble all necessary tools, including a spool, line cutter, and any additional items as specified in the operator’s manual.
Selecting the Right String for Your Model
Selecting the appropriate string for your Stihl weed eater is crucial for optimal performance and longevity. Stihl offers an array of string types, each designed for specific applications and machine models. Here’s a guide to help you choose the best option:
Round String
Round string is the most common type used in Stihl weed eaters. It is available in various diameters, from 1.5 mm to 2.7 mm. Thicker strings are more durable and can handle heavier brush, while thinner strings are more flexible and suitable for precise trimming.
Square String
Square string is less common but offers advantages for certain applications. Its square shape reduces vibration and noise, making it ideal for use in noise-sensitive areas or near buildings. Square string also resists twisting and tangling, ensuring smooth operation.
Twisted String
Twisted string combines the durability of round string with the reduced vibration of square string. It is made by twisting two or three strands of round string together, creating a stronger and more flexible option. Twisted string is a good choice for all-around use, providing both durability and noise reduction.
Line Table
To further assist your decision-making, refer to the following table for specific line recommendations based on your Stihl weed eater model:
| Model | Line Diameter | Line Type |
|---|---|---|
| FS 56 | 1.5 mm | Round |
| FS 80 | 2.4 mm | Round or Square |
| FS 90 | 2.7 mm | Round or Twisted |
Troubleshooting Common Restringing Issues
If you encounter any difficulties during restringing, consult the following troubleshooting tips:
1. Line is too long or short.
Ensure the line length aligns with the manufacturer’s recommended specifications. Trim excess line or extend if necessary.
2. Line is not cutting effectively.
Inspect the cutting head for damage or wear. Replace or repair faulty components to restore cutting performance.
3. Line is getting tangled.
Ensure proper line winding on the spool. Refer to the user manual for specific threading instructions.
4. Line is fraying or breaking.
Use high-quality trimmer line for durability. Check for worn or damaged eyelets or guides that may be causing premature line failure.
5. Line is not advancing.
Check the bump knob or line release mechanism for proper functioning. Clean any debris or obstructions that may hinder line advancement.
6. Line is wrapping around the shaft.
Adjust the trimmer head angle or use a deflector to prevent line entanglement.
7. Trimmer is vibrating excessively.
Ensure proper line installation and balance. Inspect drive components for damage or loose connections.
8. Trimmer is not starting or running smoothly.
Check for fuel and oil levels. Clean the spark plug and air filter. Refer to the user manual for additional troubleshooting.
9. Line keeps breaking at the eyelets
The eyelets may be worn or damaged. Check the eyelets for any sharp edges or burrs. If the eyelets are damaged, they will need to be replaced.
The line may be too thick for the eyelets. Check the trimmer manual to ensure that you are using the correct line size.
The line may be wound too tightly around the spool. When winding the line, make sure to leave a little bit of slack so that the line can move freely through the eyelets.
The line may be old or brittle. If the line is old or brittle, it will be more likely to break. Replace the line with new line.
