However, to maintain peak performance, it’s essential to understand how to replace the string on your Dewalt 20V XR Brushless. This guide offers a detailed walkthrough to ensure you’re well-prepared for string replacement, letting you tackle overgrown areas with ease.
Understanding Your Dewalt 20V XR Brushless String Trimmer
Before you dive into string replacement, it’s crucial to familiarize yourself with your Dewalt 20V XR Brushless. This machine is designed for both performance and convenience, featuring a lightweight build, a powerful brushless motor, and a bump feed head for easy string advancement.
Why String Replacement is Essential
String trimmers use a nylon line that wears down over time, especially with frequent usage. If you notice a decrease in cutting efficiency or if the line is continually breaking, it’s time for a replacement. Regular maintenance of your trimmer, including string replacement, will enhance its performance and prolong its lifespan.
Gather Your Tools and Materials
Before starting the string replacement process, gather the following tools and materials:
- Dewalt 20V XR Brushless String Trimmer
- Replacement trimmer line (0.080-inch diameter recommended)
- Wire cutters or scissors
- Protective eyewear
- Gloves (optional for hand protection)
Having all your materials at hand will help streamline the process and ensure safety.
Step-by-Step Guide to Replacing the String
Now that you have gathered your tools, let’s dive into the step-by-step process of replacing the string on your Dewalt 20V XR Brushless String Trimmer.
Step 1: Safety First!
Before starting any maintenance on your trimmer, prioritize safety. Turn off the machine and disconnect the battery. Wearing protective eyewear is also advised, as small debris may be ejected during the process.
Step 2: Remove the String Head
To start, you need to remove the trimmer head. Here’s how:
- Press the tabs on either side of the string head and pull it off gently. Ensure that there’s no tension before removing it to avoid damaging any components.
- Inspect the head for any wear and tear. If the trimmer head is damaged, consider replacing it.
Step 3: Measure and Cut the New String
For the Dewalt 20V XR Brushless, the recommended string diameter is 0.080 inches. Here’s how to proceed:
- Cut a length of new string. Generally, 10-15 feet is sufficient for most jobs.
- Double-check the length to ensure that you have enough line to load.
Step 4: Load the New String into the Head
Loading the new string is a critical step that affects the trimmer’s performance. Follow these instructions carefully:
- Locate the holes in the spool where the string will be fed. Most Dewalt trimmers have a dual line setup which allows for efficient cutting.
- Insert one end of the new string into the designated hole and pull it through until both ends are of equal length.
- Wind the string evenly around the spool in the direction indicated (usually counterclockwise). Make sure the string is tightly wound to prevent tangling while you trim.
Step 5: Reassemble the Trimmer Head
Once the string is properly loaded, it’s time to reassemble:
- Carefully tuck the string back into the spool’s notch to keep it secure.
- Align the spool with the head and press down until it clicks into place.
Step 6: Test the Trimmer
With the new string in place, it’s important to test the trimmer to ensure the string feeds correctly. Here’s how:
- Reconnect the battery pack.
- Turn on the trimmer to check if the string is advancing properly.
- If the string is not feeding, recheck the winding process, as improper winding can lead to feeding issues.

What tools do I need for string replacement on the Dewalt 20V XR Brushless?
To replace the string on your Dewalt 20V XR Brushless trimmer, you will primarily need a new spool of trimmer line that is compatible with your model. Make sure to check the specifications for the correct diameter of the line before purchasing. Additionally, having a pair of scissors or a line cutter can help you trim the line to the appropriate length, leading to a smoother installation process.
Besides the replacement string, it can be beneficial to have a flathead screwdriver or a wrench on hand to assist in accessing the spool cover, depending on the model you have. A clean workspace is also important to prevent any small parts or debris from getting tangled in the workings of your trimmer. Having the right tools will make the string replacement process significantly easier and more efficient.
How do I remove the old string from the Dewalt 20V XR Brushless?
To begin removing the old string from your Dewalt 20V XR Brushless trimmer, start by unplugging the trimmer or ensuring the battery is removed for safety. Locate the spool cover on the trimmer head and press the release tabs to take it off. Once you have access to the spool, carefully unwind the old string from the spool. Make sure to note how the string is wound, as this will aid in correctly installing the new string.
After you have removed the old line, inspect the spool for any signs of wear or damage. If the spool itself is damaged, it may be worth replacing it entirely to ensure optimal performance. Cleaning away any debris or grass clippings from the spool area at this point will also make the new string installation process easier and more effective.
What size trimmer line should I use for the Dewalt 20V XR Brushless?
The appropriate string size for your Dewalt 20V XR Brushless trimmer typically falls within a specific range depending on the model. Most commonly, the recommended diameter is around .080 inches or .095 inches, but it’s crucial to verify this in your user manual to ensure you are choosing the correct option. Choosing the right size line can help in achieving better cutting performance and prevent potential jamming issues during operation.
Using a trimmer line that is too thick may damage the motor or the spool, while one that is too thin may not provide adequate cutting power. Always aim to select high-quality string made from durable materials like nylon or composite, which will withstand the rigors of outdoor use. Be sure to stock up on multiple lengths and sizes if you have varying tasks or areas to work on.
How do I install new string onto the spool?
To install new string on the spool of your Dewalt 20V XR Brushless trimmer, start by cutting a length sufficient for your needs—typically around 10 to 15 feet. Once you have your desired length, locate the eyelets on the spool where the line will be threaded. Insert one end of the line into the appropriate hole, ensuring it extends out from the spool. Hold the spool securely to begin winding.
Wind the line in the direction indicated on the spool, typically marked with an arrow. Make sure to keep the winding tight and orderly, as any overlaps or loose sections can lead to tangles or snags during use. After you’ve wound the string completely, leave a sufficient length sticking out for efficient cutting; then, secure the string according to your model’s specifications before re-attaching the spool cover.
Why is my trimmer line breaking frequently?
Frequent breaking of trimmer line can often be attributed to several factors, one being the use of an incorrect line diameter. If the line is too thin for your model or the tasks at hand, it will likely snap under pressure. Additionally, low-quality trimmer line can deteriorate quicker, so always use reputable brands designed for your specific trimmer model to ensure longevity and durability.
Another reason might be improper string installation or handling. If the string is wound too loosely on the spool or if there are inconsistencies in the winding, this can create weak points that lead to breaks. Ensure the string is evenly wound and that you’re not running it through excessively tough terrain without the proper technique, as this can cause unnecessary strain on the line.
What maintenance does my Dewalt 20V XR Brushless trimmer require?
Routine maintenance for your Dewalt 20V XR Brushless trimmer is essential to ensure optimal performance and longevity. Start by regularly cleaning the trimmer, focusing on the spool and cutting head to remove any grass clippings or debris that could hinder operation. Inspect the trimmer line for wear and tear, replacing it as needed to avoid interruptions during use.
In addition to maintaining the cutting components, make sure to routinely check the battery health. Ensure it is charged and functioning properly before use to avoid unexpected downtime during a job. Keeping the moving parts lubricated and inspecting for any loose screws or damaged components will also enhance the trimmer’s longevity and efficiency.
What should I do if the trimmer line won’t advance?
If you encounter issues with the trimmer line not advancing during use, start by checking if the line is properly loaded onto the spool. If the line is tangled or incorrectly wound, this could obstruct the automatic feed mechanism. Remove the spool cover, unwind the line if necessary, and re-load it according to the manufacturer’s instructions to ensure optimal functionality.
Another common cause for this issue could be related to the altitude of the trimmer’s guard or its cutting head. Make sure the guard is not too close to the ground, as this can prevent the line from extending freely. Additionally, inspect any debris or damage around the cutting head that may be causing blocks. Once you have ensured everything is in order, perform a test run to see if the line advances correctly.
Where can I purchase replacement string for my Dewalt trimmer?
You can purchase replacement string for your Dewalt 20V XR Brushless trimmer from various sources, including home improvement stores, garden centers, or specialized tool retailers. Most of these locations carry an assortment of trimmer lines specifically designed for Dewalt products, ensuring compatibility and quality. It’s always wise to check the specifications for the proper line diameter before making a purchase.
Online retailers offer the convenience of exploring a wider selection and may even provide user reviews to help you choose the best option. Websites like Amazon, the Dewalt official site, or other e-commerce platforms can be great resources for finding high-quality trimmer line. Be sure to consider bulk purchasing if you frequently use your trimmer; this can often lead to cost savings and ensure you have enough string on hand for multiple tasks.
