Stringing in Style: Mastering the Art of Winding a Stihl Trimmer

How to Wind the Line on a Stihl Trimmer: A Step-by-Step Guide

When it comes to maintaining and using a Stihl trimmer, knowing how to properly wind the line is essential. The string, also known as the trimmer line, is what cuts through grass and weeds to give you a well-manicured lawn. In this comprehensive guide, we will walk you through the process of winding the line on a Stihl trimmer so that you can efficiently perform your trimming tasks with ease and precision.

1. Understanding the trimmer head

Before we dive into the string winding process, it’s important to become familiar with the trimmer head. Stihl trimmers typically feature a bump-feed or automatic-feed trimmer head. The bump-feed trimmer head requires manual intervention to release more string, while the automatic-feed trimmer head automatically releases the appropriate length of string as needed.

To determine the type of trimmer head you have, inspect the head assembly. If you notice a knob or button on the bottom, it is probably a bump-feed head. On the other hand, if there are no external controls, it is probably an automatic feed head. Once you have identified the type of trimmer head, you can proceed with the stringing process accordingly.

2. Choosing the Right Trimmer Line

Selecting the correct trimmer line is critical to achieving optimum cutting performance. Stihl trimmers typically accept different line diameters, ranging from 0.065 to 0.105 inches. Choosing the appropriate line diameter depends on the type of vegetation you will be trimming. For light trimming, a smaller diameter line may be sufficient, while heavier vegetation may require a thicker line.

Also consider the shape of the trimmer line. Round lines are the most common and suitable for general trimming purposes. However, if you encounter thicker grass or weeds, a square or serrated line may provide more cutting power. Be sure to consult your Stihl trimmer manual or contact an authorized dealer to determine the recommended line diameter and shape for your specific model.

3. Removing the Spool

To wind line on a Stihl trimmer, you must remove the line spool from the trimmer head. First, turn off the trimmer and remove the spark plug to prevent accidental startup. Lay the trimmer on a flat surface and locate the screws or tabs that secure the trimmer head cover. Using appropriate tools such as a screwdriver or pliers, remove these screws or tabs and carefully lift off the cover.
With the cover off, you have access to the spool. Depending on your trimmer model, the spool may have a cap or spring-loaded mechanism that holds it in place. Release the cap or mechanism and gently pull the spool out of the trimmer head.

4. String Winding Procedure

With the spool in hand, it’s time to wind the string. Start by locating the small hole or tab on the spool where the string will be inserted. This hole serves as the anchor point for the trimmer line. Insert the end of the line into the hole, leaving a small tail of about six inches. Hold the tail firmly to prevent it from slipping out during the winding process.

Wind the line in the direction indicated by the arrow on the spool. Follow a neat and even pattern, making sure that the lines are wound tightly together without overlapping. Continue winding until you reach the manufacturer’s recommended line length or until the spool is almost full, leaving enough room for reassembly.

5. Reassembling the Trimmer Head

With the line wound onto the spool, it’s time to reassemble the trimmer head. Insert the spool back into the trimmer head, making sure it aligns properly with the head assembly. If your trimmer head has a retaining cap, secure it in place. For trimmer heads with a spring-loaded mechanism, engage the mechanism to lock the spool in place.

Replace the trimmer head cover, making sure it is properly aligned with the trimmer head assembly. Tighten the screws or tabs to secure the cover, taking care not to overtighten. Once the cover is securely in place, reconnect the spark plug and you are ready to start trimming with a properly wound line on your Stihl trimmer.


Winding the line on a Stihl trimmer is a simple process that ensures optimal cutting performance. By following the step-by-step instructions above, you can confidently wind the line on your Stihl trimmer for a well-manicured lawn and efficient, precise trimming. Remember to consult your trimmer manual for specific instructions and recommendations for your model. With the right line of trimmers, proper technique and regular maintenance, your Stihl trimmer will continue to be a reliable tool in your lawn care arsenal. Happy trimming!
