Stihl weed eaters, known for their durability and power, require regular string replacement. Knowing how to string your Stihl weed eater efficiently saves time and ensures optimal performance. This guide covers various Stihl weed eater head types and provides a step-by-step process for restringing.

Choosing the Right String

Before you begin, select the correct string type for your Stihl trimmer head. Stihl recommends specific string types for their various models. Check your owner's manual or the Stihl website to confirm the recommended diameter and type (round, square, or twisted). Using the wrong type can damage your trimmer head.

Types of Stihl Trimmer Heads

Stihl offers several trimmer head designs, each with a unique restringing method. The most common types include:

AutoCut C 25-2: This automatic feed head is convenient but requires specific string loading.
AutoCut C 30-2: Similar to the C 25-2 but with a slightly larger capacity.
Tap & Go Bump Feed: This head requires manual tapping to feed the string.
Loop Handle Trimmer Heads: These heads also require different procedures.

Knowing your head type is crucial for proper restringing.

How to String a Stihl Weed Eater (Tap & Go)

The Tap & Go system is popular for its simplicity. Here’s how to restring a Tap & Go head:

Step 1: Prepare the String

Measure and cut the correct length of trimmer line. This length depends on your trimmer head's specifications, usually indicated on the head itself or in the owner's manual.

Step 2: Insert the String

Open the head's spool cover. Insert one end of the string into the spool's eyelet and feed it into the spool's channel. Carefully wind the string around the spool, ensuring it's neat and evenly distributed. Some spools have specific winding patterns to follow.

Step 3: Secure the String

Once the spool is full, tuck the string's end into the designated slot or groove to secure it. Close the head's cover.

Step 4: Test and Adjust

Tap the head lightly against the ground several times to feed the string. Adjust as needed. If the line doesn't feed, check for tangles or improper loading.

How to String a Stihl Weed Eater (AutoCut Heads)

AutoCut heads are self-feeding, but they require careful string installation. Refer to your model's specific instructions, as slight variations exist.

Step 1: Open the Head

Open the trimmer head by rotating the head's outer part counter-clockwise.

Step 2: Insert the String

Insert the correct length string into the appropriate slots. Pay close attention to the head's orientation and the string's placement. These heads typically have specific guides or notches.

Step 3: Close and Test

Close the trimmer head by rotating it clockwise until it locks. Test the feeding mechanism by running the trimmer for a short time.

Troubleshooting Common Issues

String won't feed: Check for tangles, ensure proper string loading, and make sure the head is securely closed.
String breaks easily: You may be using the wrong type or diameter of string.
Uneven string feed: The spool might not be properly wound.

Maintaining Your Stihl Weed Eater

Regular maintenance extends the life of your weed eater. This includes:

Inspecting the head: Regularly check for wear and tear.
Cleaning the head: Remove debris that can impede string feeding.
Replacing the head: Replace damaged or worn heads promptly.

Regular maintenance also ensures better performance and longevity of your Stihl weed eater.

Conclusion

Stringing your Stihl weed eater regularly is essential for optimal performance. By understanding your head type and following these steps, you can quickly and efficiently replace the string, keeping your landscaping tasks running smoothly. Remember always consult your owner’s manual for specific instructions related to your Stihl model.
