Understanding Your Craftsman Weed Eater

Craftsman produces a wide range of weed eaters for both residential and commercial use, including gas-powered, corded electric, and cordless battery-powered models. While the power source and overall design vary across these models, the string winding process for the cutting head is nearly identical across all Craftsman products. The only major difference that impacts winding is the type of cutting head your model uses, which we’ll cover in detail in the next section. Before you begin winding, it’s always a good idea to consult your owner’s manual for model-specific guidance, such as the exact string size required for your tool and any unique disassembly steps for your cutting head. Most Craftsman weed eaters also have a label on the head or in the battery compartment (for cordless models) that lists the recommended string diameter, so you don’t have to search through the manual if you don’t have it on hand.

Types of Craftsman Weed Eater Heads

Craftsman weed eaters come with two primary cutting head types, and the winding process differs slightly for each. Knowing which head you have is the first step to winding your string correctly:

• Bump feed heads: These are the most common type on residential Craftsman models. They hold a pre-wound spool of string, and you release more string by bumping the bottom of the head against the ground while the tool is running. When the string runs out, you can either replace the entire spool or rewind the existing spool with new string, which is what this guide covers.
• Fixed line heads: These are more common on heavier-duty, commercial-grade Craftsman models. Instead of a wound spool, you manually feed two (or sometimes one) lengths of string through holes in the head and secure them in place. When the string breaks, you replace both lengths entirely rather than rewinding a spool.

Most entry-level Craftsman weed eaters use bump feed heads, while larger gas-powered models for big yards or professional use often use fixed line heads. If you’re not sure which type you have, check your owner’s manual or look at the head: bump feed heads have a circular, removable spool on the bottom, while fixed line heads have small holes on the sides where string is fed through.

Tools and Materials You’ll Need

Before you start winding, gather all the necessary tools and materials to avoid interruptions mid-process. Having everything on hand will make the job faster and easier, and reduce the risk of losing small parts like screws or spools. Here’s what you’ll need:

• Replacement weed eater string: Make sure to get the correct diameter for your Craftsman model, which is usually between 0.065 and 0.095 inches for most residential models. Using string that’s too thick or too thin will cause poor performance, frequent breakage, or even damage to your tool’s motor.
• Small flathead screwdriver: Most Craftsman cutting heads are secured with a small screw that holds the spool or head cover in place. A flathead screwdriver will let you remove and reattach this screw easily.
• Scissors or heavy-duty string cutter: You’ll need this to cut the new string to the correct length and trim any excess after winding.
• Clean rag or paper towels: Grass, weeds, and dirt can build up inside the cutting head, so wiping it out before you start will prevent debris from getting tangled in your new string.
• Work gloves (optional but recommended): The sharp edges of the cutting string can cut your fingers, especially when you’re pulling it tight during winding.

If you’re rewinding an existing spool rather than replacing it, you’ll also need to remove any leftover old string from the spool before you start, which you can do by hand or with the help of the flathead screwdriver to pry out tangled pieces.

Step-by-Step Guide to Winding Craftsman Weed Eater String

While the exact steps vary slightly depending on whether you have a bump feed or fixed line head, the general process for learning How to Wind Craftsman Weed Eater? string follows the same core safety and preparation steps first. Follow these general steps before moving to the head-specific instructions later in this guide:

1. Disconnect the power source: This is the most important safety step to avoid accidental starting. For gas-powered models, remove the spark plug wire from the spark plug. For corded electric models, unplug the tool from the outlet. For cordless models, remove the battery pack from the tool. Never skip this step, even if you think the tool is off.
2. Remove the cutting head: Locate the small screw on the bottom or side of the cutting head that holds the spool or cover in place. Use your flathead screwdriver to loosen and remove the screw, then set it aside in a safe spot where it won’t get lost. Carefully pull the spool or head cover off the base of the weed eater.
3. Clean out the head: Use your clean rag to wipe away any built-up grass, weeds, dirt, or old string fragments from the inside of the head base and the spool (if you’re reusing it). Debris can cause new string to tangle or break prematurely, so this step is worth the extra minute.
4. Remove old string: If you’re reusing the spool, pull out any remaining old string and discard it. If you’re using a new spool, it will come pre-loaded with a small amount of string that you can remove to make winding easier.
5. Wind the new string (head-specific steps below): Follow the instructions for your head type (bump feed or fixed line) to wind the new string correctly.
6. Reassemble the head: Once the string is wound, place the spool or head cover back onto the base, making sure the string ends are positioned correctly in the exit holes. Tighten the screw back in place, being careful not to overtighten it, which can crack the plastic head.
7. Test the tool: Reconnect the power source (spark plug, power cord, or battery) and turn on the weed eater. Let it run for a few seconds to make sure the string feeds correctly and there are no tangles or jams. If the string doesn’t extend or the tool vibrates excessively, turn it off immediately and check that the string is wound correctly and the head is assembled properly.

These general steps apply to all Craftsman weed eater models, but the winding process for the string itself differs based on your head type, which we’ll cover in detail next.

Winding String for Bump Feed vs. Fixed Line Heads

As we mentioned earlier, the two main types of Craftsman weed eater heads require different winding techniques. Using the wrong method for your head will lead to tangles, poor cutting performance, and frequent string breakage. Below are the specific steps for each head type.

Bump Feed Head String Winding

Bump feed heads use a single spool of string that’s wound in a specific direction to allow smooth feeding when you bump the head. Follow these steps to wind a bump feed head correctly:

1. Check the winding direction: Most Craftsman bump feed heads require you to wind the string clockwise, but some models use counter-clockwise winding. Check the arrow printed on the spool or the head base to confirm the correct direction for your model. Winding in the wrong direction will cause the string to tangle and not feed properly when you bump the head.
2. Attach the string end to the spool: Most spools have a small notch or hole on the edge where you can tuck the end of the new string to hold it in place while you wind. If your spool doesn’t have a notch, you can hold the end of the string in place with your finger as you start winding.
3. Wind the string evenly: Turn the spool in the correct direction, keeping the string tight and evenly spaced across the entire width of the spool. Don’t overlap the string or leave gaps, as this will cause tangles and uneven feeding. Wind until the spool is almost full, leaving about 6 to 8 inches of string hanging out the exit hole on the side of the head.
4. Secure the string end: Once you’ve wound the spool, tuck the loose end of the string into one of the notches on the edge of the spool to hold it in place while you reassemble the head. Make sure the string is positioned correctly in the exit hole so it can feed freely when you bump the head.
5. Reassemble and test: Place the spool back into the head base, making sure the string end is aligned with the exit hole. Tighten the screw back in place, then test the tool as outlined in the general steps above.

Fixed Line Head String Winding

Fixed line heads don’t use a wound spool; instead, you feed two separate lengths of string through holes in the head and secure them in place. Follow these steps to set up a fixed line head correctly:

1. Cut two equal lengths of string: Measure and cut two pieces of string to the exact length recommended for your Craftsman model, which is usually between 8 and 12 feet for most residential fixed line heads. Make sure both pieces are exactly the same length to ensure even cutting.
2. Feed the string through the head holes: Insert one end of the first string through the hole on one side of the head, pulling it through until there is an equal amount of string on both sides of the head. Repeat with the second string, feeding it through the hole on the opposite side of the head.
3. Secure the string ends: Most fixed line heads have a small notch or clamp on the inside of the head where you can tuck the ends of the string to hold them in place. Make sure the string is pulled tight so it doesn’t slip out while you’re using the tool.
4. Trim excess string: Use your scissors or string cutter to trim the ends of the string so they are even with the edge of the head. Most Craftsman fixed line heads require the string to extend about 4 to 6 inches from the head for optimal cutting performance.
5. Reassemble and test: If your fixed line head has a removable cover, place it back over the string and secure it with the screw. Test the tool to make sure both strings are secure and cut evenly.

String Type and Size Recommendations

Using the right type and size of string for your Craftsman weed eater is critical for performance, durability, and preventing damage to your tool. The wrong string can cause frequent breakage, poor cutting power, and even strain your tool’s motor, leading to premature wear. Below is a comparison table of the most common weed eater string types to help you choose the best option for your Craftsman model.

In addition to string type, you’ll need to choose the correct diameter (size) for your Craftsman model. The most common sizes are 0.065 inches (for light-duty use) and 0.080 to 0.095 inches (for heavy-duty use). Using string that’s too thick will overload your tool’s motor, causing overheating and reduced lifespan, while string that’s too thin will break frequently and provide poor cutting performance. Check your owner’s manual or the label on your tool for the exact recommended size for your model.

Tips for Longer String Life and Better Performance

Once you’ve learned how to wind your Craftsman weed eater string correctly, follow these best practices to extend the life of your string and keep your tool running at peak performance:

• Don’t overfill the spool: Wind the string until the spool is about 90% full, leaving a small gap at the top. Overfilling the spool will cause the string to overlap and tangle, leading to jams and frequent breakage.
• Wind the string evenly and tight (but not too tight): Keep the string taut as you wind to avoid gaps, but don’t pull it so tight that it stretches or deforms the spool. Stretched string will snap more easily when you’re using the tool.
• Use the correct string size and type: As outlined in the comparison table above, using the right string for your model and use case will drastically reduce breakage and improve cutting performance.
• Clean the cutting head regularly: After each use, wipe down the inside of the head and the spool to remove grass, weeds, and dirt. Built-up debris can cause the string to jam or feed incorrectly, and can also corrode metal parts of the head over time.
• Avoid cutting near hard surfaces: Hitting rocks, concrete, or metal edging with your weed eater string will wear it down quickly and cause it to break. Try to keep the string 1 to 2 inches above hard surfaces when cutting near them.
• Store spare string in a cool, dry place: Exposure to sunlight, moisture, and extreme temperatures can make weed eater string brittle and prone to breaking. Keep spare string in a sealed container in a shaded, temperature-controlled area to extend its shelf life.

Common Mistakes to Avoid When Winding Weed Eater String

Even experienced DIYers make mistakes when winding weed eater string, leading to tangles, poor performance, and wasted time. Avoid these common errors to make the process smoother and get better results from your Craftsman tool:

• Winding the string in the wrong direction: This is the most common mistake, especially for bump feed heads. If you wind the string counter-clockwise on a model that requires clockwise winding, the string will not feed when you bump the head, and will likely tangle immediately. Always check the arrow on your spool or head base before you start winding.
• Using string that’s too thick or too thin: As mentioned earlier, the wrong string size will cause poor performance and damage to your tool. Always refer to your owner’s manual for the exact recommended size for your model.
• Not leaving enough string sticking out: For bump feed heads, you need to leave 6 to 8 inches of string extending from the exit hole. For fixed line heads, leave 4 to 6 inches. If you leave too little string, the tool won’t cut effectively, and you’ll have to bump the head constantly (for bump feed models) to get more string to extend.
• Overlooking safety steps: Failing to disconnect the power source before removing the cutting head can lead to accidental starting, which can cause serious injury. Always disconnect the spark plug, power cord, or battery before you begin any work on your weed eater.
• Overtightening the head screw: The screw that holds the cutting head in place is usually made of plastic, and overtightening it can crack the head or strip the threads, making it impossible to remove the head later. Tighten the screw until it’s snug, but don’t use excessive force.

Frequently Asked Questions

Below are answers to the most common questions about winding Craftsman weed eater string, to help you troubleshoot issues and get the best results from your tool.

How often should I wind my Craftsman weed eater string?

The frequency with which you need to wind or replace your Craftsman weed eater string depends on how often you use the tool and what you’re cutting. For light residential use (cutting grass and weeds around a small yard once a week), you’ll likely need to replace or rewind the string every 2 to 3 months. For heavier use (cutting thick brush or large yards), you may need to replace the string every few weeks. If you notice the string breaking frequently, not cutting effectively, or not feeding properly when you bump the head, it’s time to rewind or replace it.

What size string does my Craftsman weed eater use?

Most Craftsman residential weed eaters use 0.065 inch or 0.080 inch diameter string, while larger gas-powered models use 0.095 inch string. The exact size for your model is listed on a label on the tool itself, usually on the battery compartment (for cordless models), the handle, or the cutting head base. You can also find the recommended size in your owner’s manual. Using the wrong size string will lead to poor performance and potential damage to your tool.

Why does my weed eater string keep breaking after winding?

There are several common reasons why your newly wound Craftsman weed eater string keeps breaking: you used the wrong string size or type for your model, you wound the string too tight causing it to stretch and snap, you overfilled the spool leading to tangles, you’re cutting near hard surfaces like rocks or concrete, or you wound the string in the wrong direction causing it to jam and break. Check each of these factors to troubleshoot the issue, and follow the steps in this guide to wind the string correctly next time.

Can I use generic replacement string for my Craftsman weed eater?

Yes, you can use generic replacement string for your Craftsman weed eater as long as it matches the exact diameter and type recommended for your model. You do not need to use official Craftsman-branded string, though some users prefer it for guaranteed quality. Just make sure the generic string meets the size and material requirements for your tool to avoid performance issues or damage.

How do I know if my Craftsman weed eater has a bump feed or fixed line head?

You can tell which type of head your Craftsman weed eater has by looking at the design of the cutting head. Bump feed heads have a circular, removable spool on the bottom of the head, and you release more string by bumping the bottom of the head against the ground while the tool is running. Fixed line heads do not have a removable spool; instead, they have small holes on the sides of the head where you feed string through manually. If you’re still unsure, check your owner’s manual, which will specify the head type for your model.

What should I do if my string keeps tangling after winding?

If your newly wound string keeps tangling, first check that you wound it in the correct direction for your head type (check the arrow on the spool for bump feed heads). Next, make sure you didn’t overfill the spool, as excess string will overlap and tangle. For bump feed heads, make sure the string is positioned correctly in the exit hole and not caught on any part of the head. For fixed line heads, make sure both lengths of string are the same length and fed evenly through the holes. If tangling persists, remove the string and rewind it, making sure it’s taut and evenly spaced across the spool.

Conclusion

Learning How to Wind Craftsman Weed Eater? string is a simple, valuable skill that will save you money on replacement spools and keep your yard tool running at peak performance for years. The process is quick and easy once you understand your cutting head type, gather the right tools, and follow the step-by-step instructions outlined in this guide. Whether you have a bump feed or fixed line head, using the correct string size and type, avoiding common mistakes, and following basic maintenance tips will ensure your string lasts as long as possible and your Craftsman weed eater cuts through grass and weeds efficiently. The next time your string runs out or breaks, you won’t need to make a trip to the store for a pre-wound spool—you can wind it yourself in just a few minutes with tools you already have at home.
