Step-by-Step Guide to Adding String to Dewalt DCST920
Adding string to your Dewalt DCST920 is a simple process when broken down into clear steps. We’ll guide you through the entire process to ensure that you can get back to your trimming tasks with ease.
Step 1: Safety First
Before you begin the process, make sure to prioritize safety by following these actions:
- Power Down: Ensure the trimmer is turned off and unplugged (if applicable) to avoid any accidental start.
- Wear Protective Gear: Use gloves and goggles to guard against injury from debris or accidental cuts.
Step 2: Removing the Spool Cap
The spool cap is the part that holds the string spool in place, and it requires careful removal to avoid damage.
- Locate the spool cap on the trimmer head.
- Press the tabs located on the spool cap to release it.
- Gently pull the spool cap off, revealing the inner spool.
Step 3: Removing the Old Spool
Now that the spool cap is off, the next step involves removing the existing spool of string.
- Grasp the spool and pull it gently out of the trimmer head.
- Dispose of the old line responsibly, depending on local recycling guidelines.
Step 4: Preparing the New String
It’s essential to use the right kind of trimmer line, typically a dual line measuring 0.080 inches in diameter for the DCST920.
- Cut a length of the replacement string. A handy length is around 25-30 feet, but always check your user manual for specific dimensions.
Step 5: Threading the New String
Now for the most crucial part—threading the new string into the spool.
- Take one end of the string and find the opening designated for the line on the spool.
- Insert the end of the string into the hole and pull it through until approximately half of the line is on either side.
- Start winding the string around the spool, following the directional arrows printed on the spool itself. This ensures proper winding, which is vital for effective performance.
- Tip: Maintain even tension while winding to prevent tangles.
Step 6: Installing the Spool Back into the Trimmer
With your new line securely wound, it’s time to reassemble the trimmer.
- Take the spool and carefully place it back into the trimmer head, aligning it correctly.
- Pull the two ends of the line outwards to ensure they are exposed.
- Reattach the spool cap by aligning it over the spool and pressing down until you hear a click.
Finalizing Your Trimmer Setup
With the string now replaced, it’s time to finalize the setup.
- Inspect Your Work: Ensure that the spool is correctly seated and that the line is properly threaded.
- Conduct a Trial Run: Power on the trimmer and test it briefly to ensure the new string is functioning properly.
Maintenance Tips to Extend Your Trimmer’s Life
To keep your Dewalt DCST920 performing at its best, consider these maintenance tips:
- Regularly Check Line Length: Make it a habit to check the string length regularly and replace it if it gets worn or too short.
- Keep it Clean: After every use, wipe down the trimmer to remove debris and grass clippings that can hinder performance.
- Store Properly: Ensure that your trimmer is stored in a dry, cool place to prevent rust or degradation of its components.

What is the Dewalt DCST920 and how does it work?
The Dewalt DCST920 is a cordless string trimmer that is designed for efficient landscaping and yard maintenance. It is powered by a high-performance brushless motor which delivers durability and longer runtime. Equipped with a lightweight design and a telescoping shaft, it allows for easy maneuverability and customization to fit your height. The string trimmer utilizes a 20V battery system, providing ample power for cutting through tough weeds and grass.
Its automatic feed spool (AFS) feature ensures that the string is consistently delivered to the cutting head without manual intervention. This design eliminates interruptions during your work, allowing for a more seamless and productive yard care experience. Furthermore, the DCST920 is built with a dual 0.080-inch line which enhances its cutting capability, making it suitable for both residential and commercial applications.
How do I add string to my Dewalt DCST920?
Adding string to your Dewalt DCST920 is a straightforward process that ensures you are ready for the task at hand. First, ensure that the trimmer is powered off and the battery is removed for safety. Locate the spool cover at the base of the trimmer; you can usually press the tabs on either side to release it. Once the cover is removed, you will find the spool of string inside, which should be carefully unwound to avoid tangles.
To replace or refill the string, remove the old spool if necessary and wind the new string evenly around the spool, following the directional arrows provided on the spool housing. Once it is adequately wound, thread the ends of the string through the eyelets located in the trimmer head and replace the spool cover. It is essential to ensure that the string is at the correct length and that it moves freely to avoid any operational issues during use.
What type of string should I use with the DCST920?
The Dewalt DCST920 is compatible with a variety of trimmer lines, but it is recommended to use dual-line trimmer string with a diameter of 0.080 inches for optimal performance. This specific size strikes a good balance between durability and cutting efficiency, allowing for effective trimming of grass and weeds without excessively wearing down the motor. Dewalt also offers proprietary strings that fit perfectly with their tools, ensuring compatibility and performance.
While you can use other brands, ensure you check if they meet the specifications for your trimmer. Using the correct type and diameter of string will not only enhance the trimmer’s performance but also prolong its lifespan. Always refer to the user manual for the best practices regarding line types and sizes to maintain the trimmer’s efficiency and safeguard against potential damage.
How often should I replace the string in my DCST920?
The frequency of string replacement for your Dewalt DCST920 largely depends on the amount of use and the types of vegetation you are cutting. For regular yard maintenance, you might find that replacing the string every few weeks is sufficient. However, if you are using the trimmer in tougher conditions with dense weeds or tough grasses, you may need to replace the string more frequently, possibly every few hours of operation.
To maximize efficiency, keep an eye on the length of the string and how well it is performing. If you notice that the string is fraying, breaking, or not feeding correctly, it’s time to replace it. Regular maintenance not only ensures optimal performance but also prevents overworking the motor, which can lead to additional wear and tear on the trimmer.
Can I use the DCST920 for commercial landscaping?
Yes, the Dewalt DCST920 is suitable for both residential and commercial landscaping applications. Its powerful brushless motor provides enough durability and efficiency to handle larger jobs often associated with commercial landscaping. The lightweight design also aids in reducing operator fatigue, making it a practical choice for landscaping professionals who need to be productive over extended periods.
However, while the DCST920 is robust enough for moderate commercial tasks, for continuous heavy use, you may also want to consider other models in the Dewalt lineup specifically designed for such applications. Using the DCST920 for its intended home and light commercial tasks can lead to excellent results as long as it is maintained properly and the appropriate string is used.
What maintenance do I need to perform on my DCST920?
Maintaining your Dewalt DCST920 is essential to ensure its longevity and optimal functionality. Regular checks should include ensuring the battery is charged and clean, inspecting the cutting head and string for any wear and tear, and keeping the motor air vents clear of debris. Regularly changing the trimmer line, as previously mentioned, will also prevent clogs and reduce stress on the motor.
Additionally, it is advisable to clean the exterior of the trimmer to prevent dirt and grass build-up, which can lead to overheating. Inspect the shaft and joints for any signs of damage or excessive wear, and lubricate moving parts as necessary to keep the unit operating smoothly. Always refer to the user manual for specific maintenance guidelines and schedules for your model, as following these can greatly extend the life of your string trimmer.
Is the Dewalt DCST920 compatible with other Dewalt batteries?
Yes, the Dewalt DCST920 is compatible with the Dewalt 20V MAX battery system. This means that as long as you have a 20V MAX battery, it can be used interchangeably among various Dewalt tools designed for this voltage. This versatility is a significant advantage if you have multiple Dewalt tools, as it allows for easy battery swapping without the need to purchase additional batteries.
It’s important to note that while using compatible batteries, the performance may vary based on the battery’s amp-hour (Ah) rating. Higher amp-hour batteries will provide longer runtimes, making them beneficial for larger projects. Always select a battery that matches the demands of your work to ensure the best performance from your Dewalt DCST920.
