Step-by-Step Guide to Changing the String
Step 1: Prepare for String Replacement
Before starting, ensure that your trimmer is turned off and has been disconnected from any power source if applicable. It’s crucial to take safety precautions, so wear safety gloves and goggles to protect yourself from any debris.
Step 2: Remove the String Spool
To access the string, you’ll have to remove the spool. Here’s how:
- Locate the Spool Release Button: This button is usually found at the bottom of the trimmer head.
- Press the Release: Gently press this button while simultaneously twisting the spool counterclockwise to detach it from the trimmer.
Step 3: Remove Old String
Once the spool is removed, you will see the old string:
- Take note of how the string was wound: This will be crucial when you wind the new string.
- Unwind and discard: Carefully unwind the old string and dispose of it properly.
Step 4: Prepare the New String
Now it’s time to prepare the new string:
- Cut the String to Length: Depending on your specific model, cut about 15-20 feet of new string. This length will vary, so always refer to your user manual for specifications.
- Follow Manufacturer Recommendations: Using the right diameter for the string is critical. Dewalt typically recommends a 0.080″ diameter string for their 20V MAX trimmers, but it’s wise to check your manual to confirm.
Step 5: Wind the New String on the Spool
This is where attention to detail comes in:
- Locate the Spool Slots: You should see holes or slots where the string will fit.
- Insert the String: Thread one end of the new string through the hole designated for the string.
- Wind the String in the Correct Direction: Remember to wind the string in the same direction as indicated by the arrows on the spool. This ensures that the string feeds correctly as you use the trimmer.
- Secure the String: Make sure to leave a few inches of string hanging out of the spool.
Step 6: Reattach the Spool
Now that the new string is in place, it’s time to put the spool back on:
- Insert the Spool: Align the spool with the trimmer head and push it back into place while twisting clockwise until it clicks.
- Trim Excess String: If there’s any extra string, trim it down to the recommended length as per your user manual.
Step 7: Final Checks
Before you start using your trimmer again, here are a few final checks:
- Align the Guard: Make sure the guard is properly aligned before starting the trimmer.
- Test the String Feed: Turn the trimmer on briefly to ensure that the string feeds out smoothly and functions correctly.

What is the Dewalt 20V MAX string replacement process?
The string replacement process for the Dewalt 20V MAX involves removing the old string from the trimmer’s head, cutting the new string to the appropriate length, and then inserting it into the head. Start by ensuring the trimmer is turned off and the battery is removed for safety. Release the spool by pressing the tabs on the outer casing, which will allow you to detach it easily. Once you have access to the spool, carefully unwind the old string from it.
After removing the old string, take the new string—preferably a gauge that is compatible with your model, usually a .080 diameter—and cut it to the desired length, often around 10-15 feet. Insert one end of the string into the appropriate hole in the spool and begin winding it in the direction indicated by the arrows on the spool. Once you’ve wound the string completely, feed the remaining length through the eyelets, reattach the spool, and you’re good to go!
What type of string should I use for my Dewalt 20V MAX?
For your Dewalt 20V MAX trimmer, it is best to use a string that is specifically designed for electric trimmers—preferably one from Dewalt or a compatible brand. The recommended size is typically .080 inches in diameter, providing a perfect balance between durability and cutting efficiency. Some users prefer round strings for general trimming, while others may opt for twisted or serrated options depending on their specific cutting needs.
Choosing the right type of string can significantly affect performance. A thicker string may offer better cutting power and durability but could potentially strain the motor if it’s too heavy. Conversely, a thinner string may need frequent replacements but can be less demanding on the tool. Always refer to the user manual for specifications to ensure that you choose a string that works best with your tool.
How often should I replace the string in my Dewalt trimmer?
The frequency of string replacement depends on several factors, such as the type of vegetation you’re cutting, the thickness of the string, and the overall usage of the trimmer. If you are consistently trimming thick grass or weeds, you may find yourself needing to replace the string more frequently—possibly every few uses. On the other hand, if you are using the trimmer for light maintenance or edging, you might only need to replace the string every few weeks.
It’s also advisable to check the string before starting any significant job. If you notice that the string is frayed or excessively worn, it’s best to replace it to maintain efficiency and avoid any interruptions while working. Regularly inspecting and replacing the string not only enhances performance but also prolongs the life of the trimmer.
Can I use different brands of string with my Dewalt trimmer?
Yes, you can use different brands of string with your Dewalt 20V MAX trimmer as long as the string meets the recommended specifications. It is essential to ensure that any alternative string you choose is compatible in terms of diameter and type. This means sticking to a size of around .080 inches and considering the design—such as round, twisted, or serrated—based on your cutting needs.
While using brand alternatives is often acceptable, it is crucial to pay attention to the quality of the string. Cheap or low-quality strings might break easily, leading to more frequent replacements and decreasing the performance efficiency of your trimmer. Always check user reviews for any brand you consider to ensure that you are making a valuable choice in string quality and performance.
What tools do I need for string replacement?
You typically do not need many tools for string replacement on the Dewalt 20V MAX trimmer, making the process straightforward and hassle-free. Most importantly, you should have the new string on hand. Besides that, a pair of scissors or pruners is often useful for cutting the string to the required length. If your model requires any disassembly, it might also help to have a screwdriver or Allen wrench ready.
It’s also highly recommended to wear safety gloves during the process for added protection, especially when handling sharp tools or strings. Furthermore, using safety goggles can prevent any debris from getting in your eyes while you work. Overall, a minimal toolset is needed, making it easy for anyone to perform string replacements effectively.
How can I tell if my trimmer head is damaged?
Identifying damage to the trimmer head can be crucial for maintaining the efficiency of your Dewalt 20V MAX. Common signs of damage include visible cracks, warping, or difficulty in winding the string properly around the spool. If you notice that the trimmer head is not securely attaching to the body of the tool or if it spins irregularly, these could be indications of wear or damage that may need addressing.
Another key sign to look for is if the string continues to break or wear down faster than normal. This could also suggest that the trimmer head is not functioning correctly or that there may be an internal problem. In such cases, it’s advisable to refer to the user manual for guidance or consult a professional technician for repairs to ensure optimal performance.
Is it necessary to clean the trimmer before string replacement?
Cleaning the trimmer before string replacement is highly recommended to ensure optimal performance and longevity of the tool. Dirt, grass clippings, and debris can accumulate around the trimmer head and lead to complications during operation. A thorough cleaning helps prevent issues such as premature wear or blockages that can hinder the proper functioning of the trimmer.
To clean your trimmer, use a brush or cloth to remove any debris. Make sure to inspect the area around the trimmer head carefully to remove any tangled strings or remnants that could interfere with string replacement and cutting performance. Regular cleaning and maintenance not only enhance operational efficiency but also help in prolonging the life of your equipment.
What safety precautions should I take while replacing the string?
When replacing the string on your Dewalt 20V MAX, safety should always be your top priority. First and foremost, ensure that the trimmer is completely powered off, and remove the battery to prevent any accidental activation. Additionally, it is a good practice to work in a well-lit area to allow for better visibility, reducing the risk of accidents or mistakes.
Wearing safety gear is also highly advisable. Safety goggles can protect your eyes from debris, and gloves can safeguard your hands while handling sharp objects or when winding the string. Moreover, be cautious with the spool and trimmer head; always handle them gently to avoid injury. Following these safety precautions will help ensure a smooth and safe string replacement experience.
