Step-by-Step Guide to Replace String on Dewalt DCST920 Trimmer
Replacing the string on your Dewalt DCST920 is a straightforward process that can be completed in a few simple steps. Let’s break it down:
Step 1: Disassemble the Trimmer Head
The first thing you need to do is disassemble the trimmer’s spool head. Following these steps will make this process easier for you:
- Turn Off the Trimmer: Ensure the trimmer is turned off and the battery is removed. Safety first!
- Locate the Spool Cap: Look at the trimmer head for the spool cap. The cap typically has tabs or slots.
- Remove the Spool Cap: Press the tabs together or twist the cap counter-clockwise to detach it from the head. You may need to give it a firm tug to release it.
Step 2: Remove the Old String
Once the spool head is exposed, it’s time to remove the old string.
- Take Out the Spool: Gently lift out the spool from the trimmer head.
- Discard Old String: Cut the remaining old string away from the spool, and dispose of it properly. If there are remnants stuck in the spool, make sure to remove them as well.
Step 3: Prepare the New String
Now, let’s prepare the new string for loading into the trimmer spool.
- Cut the New String to Length: A good rule of thumb is to use a length of approximately 20 feet of replacement string for the DCST920. Cut it to size using your scissors or cutting tool.
- Identify the String Direction: Check the diagrams usually located on the spool for the correct winding direction.
Step 4: Wind the New String onto the Spool
With the preparation complete, it’s time to load the new string onto the spool.
- Insert One End of the String: Take one end of the cut string and insert it into the designated hole on the spool.
- Begin Winding: Wind the string around the spool in the direction indicated. Maintain consistent tension while winding to avoid overlap and tangling. Continue until you have approximately 10-11 inches of string remaining on each side.
- Secure the String: Once you’ve reached the desired length, tuck the ends of the string into the slots or notches designed to hold the string in place on the spool.
Step 5: Reassemble the Trimmer Head
Now that the new string is securely attached, it’s time to put the spool back into the trimmer head.
- Reinsert the Spool: Align the spool back into the trimmer head, ensuring it fits securely into place.
- Thread the String: Pull the free ends of the string out from the spool through the eyelets on the trimmer head. This step is important for ensuring proper operation.
- Replace the Spool Cap: Position the spool cap back on the trimmer head and press down or twist in place until it’s firmly secured. You may hear a slight click indicating it’s locked in.
Step 6: Reattach the Battery and Test
After reassembling the trimmer head, you’re almost ready to cut some grass.
- Reinsert the Battery: If you had removed the battery, reinsert it into the trimmer.
- Test the Trimmer: Finally, test the trimmer in an open area to ensure that the string operates correctly. Look for any signs of tangling or incorrect operation.

What type of string is compatible with the Dewalt DCST920 Trimmer?
The Dewalt DCST920 Trimmer is designed to work with .080-inch (2.0mm) or .095-inch (2.4mm) diameter string line. When selecting string, it’s crucial to choose a type that’s designed specifically for your trimmer model to ensure optimal performance. You can also consider using specialty lines, such as those designed for heavy-duty applications, which can offer improved durability and cutting efficiency.
Moreover, consider the shape of the string as well. Round strings provide a clean cut, but you may also find star or square shapes that offer enhanced cutting power for tougher weeds and grass. Always refer to the manufacturer’s recommendations to ensure you’re using the best type of line for your specific needs.
How do I replace the string on my Dewalt DCST920 Trimmer?
Replacing the string on your Dewalt DCST920 Trimmer is a straightforward process. Start by ensuring the trimmer is powered off and disconnect the battery for safety. Next, locate the spool retainer and press it to release the spool. Remove the old string from the spool and inspect the spool for any damage, replacing it if necessary.
To install the new string, cut two lengths of your chosen line, each around 25 feet long. Feed one end of the first line through the hole in the spool and wind it in the direction indicated on the spool, securing it with the retainer clip. Repeat the process with the second line. After both lines are securely attached, reattach the spool to the trimmer, ensuring it locks into place.
What are the signs that my trimmer string needs to be replaced?
There are several noticeable signs that indicate your trimmer string needs to be replaced. One of the most obvious signs is a frayed or worn string, which can lead to reduced cutting efficiency. If you find that the trimmer struggles to cut through grass or weeds, or if the string frequently breaks, it’s a clear indicator that it’s time for replacement.
Another sign is the length of the string remaining on your spool. If you notice there isn’t enough string left to complete your trimming job, it’s wise to replace the string before starting. Regular inspections after each use will help you determine the condition of your string and ensure optimal performance during trimming tasks.
Can I use a different diameter string on my Dewalt DCST920 Trimmer?
While it may be tempting to use a different diameter string, it is highly recommended to stick with the manufacturer-specified diameters of .080-inch or .095-inch for the Dewalt DCST920 Trimmer. Using a string that is too thick can lead to motor strain and potentially burn out the trimmer, while a string that is too thin may not provide adequate cutting power.
Moreover, using an incorrect diameter can interfere with the trimmer’s line feed system, causing it to malfunction. To ensure the best results and maintain your trimmer’s longevity, always opt for the recommended string diameters suitable for your model.
How can I extend the life of my trimmer string?
Extending the life of your trimmer string involves a mix of proper usage and maintenance techniques. First, avoid excessive contact with hard surfaces like concrete and asphalt, as this can cause premature wear on the string. Instead, try to keep the trimmer head slightly elevated while cutting around edges and hard surfaces.
Additionally, storing your trimmer properly can also help prolong string life. Keep the trimmer in a cool, dry place away from direct sunlight when not in use, as UV exposure can degrade the string. Regularly checking and replacing worn strings before they break can also help ensure that you have a consistently effective trimming experience.
What are some common mistakes to avoid when replacing the string?
One common mistake when replacing the string on your Dewalt DCST920 Trimmer is failing to wind the string in the correct direction. It’s crucial to pay attention to the arrows or instructions on the spool, as winding in the wrong direction can lead to tangling and ineffective operation. Always ensure you are following the recommended winding direction for smooth performance.
Another mistake is using overly long string lengths. While it’s tempting to use longer pieces for improved reach, excessive string can cause the trimmer to overwork, resulting in poor performance and potential damage. Stick to the recommended length when cutting your string to ensure it operates efficiently and effectively.
Where can I find replacement string for my Dewalt DCST920 Trimmer?
Replacement string for your Dewalt DCST920 Trimmer can be found at most home improvement stores, garden centers, and many online retailers. It’s best to purchase string from reputable brands or directly from Dewalt to ensure compatibility and quality. Checking customer reviews before buying can also help you find a high-performance string that meets your needs.
Many retailers offer a range of string options, including different diameters and shapes, allowing you to choose the best fit for your specific trimming tasks. Always remember to double-check the specifications on the package or product listing to confirm that the string is compatible with the Dewalt DCST920 model before making your purchase.
