Before you begin the restringing process, it’s essential to gather all the necessary tools and materials. Here’s what you’ll need:
Essential Tools and Materials
- Replacement trimmer line (recommended size is generally 0.080 inches for the DCST991).

Step-by-Step Guide to Restringing Your DeWalt DCST991 Cordless Weed Eater
Restringing your DeWalt DCST991 may seem daunting at first, but by following these steps carefully, you can do it in no time.
Step 1: Prepare Your Workspace
Choosing a clean and well-lit area will help you perform the task more efficiently. Make sure to power off the weed eater and disconnect the battery. This is a safety precaution to ensure that the trimmer doesn’t accidentally start while you are working on it.
Step 2: Access the Spool
The spool is where the trimmer line is housed. To access it:
- Locate the button on the trimmer head. This is commonly found at the top.
- Press the button while simultaneously pulling the spool assembly straight off the trimmer head. This may require a bit of pressure.
- Inspect the spool for any damaged parts and clean any debris that may have accumulated.
Step 3: Remove Old Line
Once the spool is exposed, it’s time to discard the old and worn-out trimmer line.
- Unwind the old line from the spool. You can cut it off or pull it out, depending on how damaged it is.
- Make sure you remove any debris trapped in or around the spool that could affect the line’s performance.
Step 4: Measure and Cut the New Line
Using the replacement trimmer line:
- Cut a piece of the new trimmer line measuring approximately 10 to 15 feet. The length can vary depending on your specific requirements but generally, this is the recommended size for efficient trimming.
- Ensure the ends of the line are even and free of any tangles.
Step 5: Load the New Line onto the Spool
To load the new line onto your spool effectively:
- Identify the line feed holes on the spool.
- Insert one end of the trimmer line through one of the holes, leaving a few inches of line hanging out.
- Wrap the line around the spool in the direction indicated on the spool. This direction is typically marked with an arrow.
- Continue wrapping the string until you have filled the spool to the notches or recommended maximum limit.
- Once filled, push the spool ends into the spool holes to secure the line in place.
Step 6: Reassemble the Trimmer
Now that the spool is properly loaded with new line, it’s time to reattach it:
- Align the spool with the trimmer head and press down firmly until it clicks into place.
- Make sure that the line is clear of any obstructions, ensuring a smooth feeding experience when you use the trimmer.
Step 7: Test the Weed Eater
With everything reattached, it’s time to make sure everything is working correctly:
- Reconnect the battery to your DeWalt DCST991.
- Turn the trimmer on at a low speed and listen for any unusual sounds coming from the motor.
- Check how the new line feeds. If the line doesn’t feed out as expected, you may have to retighten the spool or readjust the line.

What type of restringing line is recommended for the DeWalt DCST991?
The DeWalt DCST991 is compatible with various types of trimmer line, but it is highly recommended to use a .080-inch round line for optimal performance. This size strikes a balance between durability and efficiency, allowing you to tackle tough weeds without easily breaking the line. It’s also worth checking the manufacturer’s guidelines to ensure compatibility, as using the wrong size can impede the weed eater’s performance.
Additionally, you might consider a line with added features, such as a braided or spiral design, which can enhance cutting efficiency and impact resistance. Such advanced lines can be particularly beneficial for thick or overgrown grass and weeds. Always ensure you have fresh, unworn line to make the most of your tool’s potential.
How do I remove the old trimmer line from my DeWalt DCST991?
Removing the old trimmer line from your DeWalt DCST991 involves a straightforward process. First, ensure the weed eater is powered off and the battery is removed for safety. Locate the bump head at the bottom of the trimmer, and push down on the tabs to release the spool cover. Once the cover is off, you can easily pull out the old line from the spool.
After removing the line, take a moment to clean the spool area to remove any debris that may have accumulated. This step helps to ensure the new line feeds properly and reduces the risk of breakage due to obstructions. With the old line removed, you’re ready to proceed with restringing for optimal cutting performance.
What is the process for restringing the DeWalt DCST991?
Restringing the DeWalt DCST991 involves a few simple steps to ensure a smooth operation. Start by cutting a new length of your chosen trimmer line (approximately 15 feet is a good standard), and then find the central slot on the spool. Thread the line through this slot and wind it in the direction indicated on the spool, ensuring it is evenly distributed and secured.
Once the line is properly wound, insert the ends of the line into the exit holes of the spool. To finish, replace the spool cover by aligning it with the tabs and pressing down until it snaps back into place. Lastly, gently pull on the line to ensure it is free and moves smoothly. Your weed eater should now be ready for efficient weed trimming.
How often should I restring my DeWalt DCST991?
The frequency of restringing your DeWalt DCST991 depends largely on how often you use the tool and the conditions in which you are working. If you’re tackling regular garden maintenance in normal conditions, you may only need to restring once every few uses. However, if you are working in dense or tough environments, you might find that you need to replace the line more frequently—potentially every use or every few hours of operation.
Monitoring the performance of your weed eater is key. If you notice a decline in cutting efficiency or the line breaks consistently, it’s a good indicator that you need to restring. Regular inspection and maintenance of the trimmer line can ensure that your weed eater operates at its best, prolonging its lifespan and improving your overall experience.
What safety precautions should I take while restringing the weed eater?
Safety is paramount when restringing your DeWalt DCST991. Begin by ensuring that the tool is turned off and the battery is removed before you start any maintenance work. This precaution will prevent accidental activation while you are handling the trimmer line and spool. Wearing protective gloves and eyewear is also advisable, as the line can snap back while you are winding it, posing a risk of injury.
Additionally, always work in a well-lit environment to ensure that you can see all parts clearly. If you are unsure about any step in the restringing process, refer to the user manual for guidance. Taking these precautions can help reduce the risk of accidents and make your restringing experience safer and more efficient.
Can I use alternative materials for restringing instead of trimmer line?
While it might be tempting to use alternative materials for restringing your DeWalt DCST991, it is not recommended. Trimmer line is specifically designed to withstand the demands of cutting dense vegetation and handle the high-speed operation of the weed eater. Materials like string, wire, or other types of line can break easily and may even damage the trimmer itself, leading to potential malfunctions or reduced performance.
Using the correct trimmer line not only enhances efficiency but also helps to maintain the warranty of your tool. To ensure optimal performance and durability, stick to using manufacturer-recommended line types and sizes. This approach ensures that your weed eater performs safely and effectively, ultimately saving you time and money in the long run.
