While it may seem daunting, understanding how to restring your DeWalt trimmer efficiently can save you both time and money, allowing you to get back to mowing down those weeds and grass. In this detailed guide, we will walk you through the process of restringing your DeWalt DCST920 trimmer, ensuring you can tackle this task on your own with confidence.

Understanding Your DeWalt DCST920 Trimmer

Before we dive into the restringing process, let us first familiarize ourselves with the DeWalt DCST920 trimmer. This powerful tool is designed for both professional landscapers and DIY enthusiasts. It features a lightweight design, a high-performance motor, and a dual 0.080-inch line for efficient trimming.

Key Components of the DeWalt DCST920

Understanding the various parts of your trimmer will make the restringing process easier:

The Spool

The spool holds the trimmer line. Over time, the line wears down or breaks, requiring you to replace it.

The Trimmer Line

The line is what actually does the cutting. It comes in various diameters, but for the DCST920, 0.080 inches is the most commonly used size.

The Bump Head Mechanism

This feature allows you to extend the line by bumping the trimmer head against the ground during use.

Gather the Necessary Tools and Materials

To successfully restring your DeWalt DCST920 trimmer, you will need some basic tools and materials.

  • Replacement trimmer line (0.080 inches)
  • Pair of scissors or utility knife
  • Flathead screwdriver (optional)
  • Safety goggles to protect your eyes
  • Gloves to protect your hands

Having these items on hand will ensure a smooth and efficient restringing process.

Step-by-Step Guide to Restringing the DeWalt DCST920 Trimmer

Now that you understand the basics and have your materials ready, let’s get into the step-by-step process for restringing your trimmer.

Step 1: Prepare Your Tool

Safety First: Before beginning any maintenance on your trimmer, make sure it is powered off and unplugged (if applicable). Additionally, wear safety goggles and gloves to protect yourself.

  1. Inspect the Trimmer: Look for any signs of damage or wear. This includes checking the spool, drive shaft, and bump head.

Step 2: Remove the Spool

  1. Detach the Spool Cap: Use your hands to press the tabs on either side of the spool cap and lift it off gently. If it proves difficult, a flathead screwdriver can help pry it off without damaging the plastic.

  2. Take Out the Spool: Carefully lift the spool from the trimmer head and set it aside.

Step 3: Remove the Old Line

  1. Discard the Worn Line: Cut off the old trimmer line. If the line is frayed or broken, remove all of it to make way for the new line.

  2. Clean the Spool: Take this opportunity to clean any debris from the spool to ensure optimal performance.

Step 4: Cut the New Trimmer Line

  1. Measure and Cut the Line: For the DeWalt DCST920, cut two lengths of trimmer line, each around 10-12 feet long. This length ensures you have sufficient line for both sides of the spool.

Step 5: Load the New Line onto the Spool

  1. Locate the Spool Holes: The spool will have one or two holes. Insert one end of the trimmer line into the hole on one side of the spool and pull it through, leaving approximately 6 inches of line sticking out.

  2. Wind the Line: Begin winding the line around the spool in the direction of the arrows on the spool. Ensure the line is neatly coiled without overlaps, as this can prevent proper functioning.

  3. Repeat the Process: Do the same with the second line on the opposite side of the spool, making sure they are loaded in the correct direction.

Step 6: Secure the Line

  • Insert the Ends: Once both lines are loaded, insert the ends of each line into the notches on the spool to hold them in place.

  • Replace the Spool: Insert the spool back into the trimmer head. Ensure that it fits snugly and does not wobble.

Step 7: Reattach the Spool Cap

  1. Align the Cap: Place the spool cap back on the trimmer head.

  2. Snap into Place: Press down on the cap until you hear a click, indicating it is secured. Make sure there are no gaps between the cap and the trimmer head.

Step 8: Test the Trimmer

  1. Power On: Turn the trimmer on to check if the line extends correctly as you bump the head against the ground.

  2. Check Performance: Test the trimmer with a few passes over your grass or weeds to ensure the new line is cutting effectively.

Additional Tips for Maintaining Your DeWalt DCST920 Trimmer

Once you have completed the restringing process, consider these additional maintenance tips to keep your DeWalt trimmer in top shape:

Regular Inspection

Inspect your trimmer before and after use, checking for damage to the line, spool, and any other parts. Catching issues early can save you from more significant problems down the road.

Choose the Right Trimmer Line

Using the correct diameter and type of line is crucial for optimal performance. For the DeWalt DCST920, be sure to stick to 0.080 inches for the best results.

Store Properly

After use, store your trimmer in a dry place away from extreme temperatures and moisture. This will help preserve both the tool and the line.

Troubleshooting Common Issues

While restringing your DeWalt DCST920 trimmer is relatively easy, you may encounter a few common issues. Here are some quick fixes:

Line Breaks Frequently

If the trimmer line keeps breaking, ensure that it is not tangled when reloading. Also, check for a dull spool that may require replacement.

Line Doesn’t Feed

If the line does not feed correctly, ensure it is wound properly around the spool and inserted into the notches fully. You may also need to check the bump head mechanism for any blockages.

Unusual Noises

Strange noises during operation can indicate problems with the motor or spool. Turn off the trimmer immediately and inspect for any visible issues.

Conclusion

Restringing your DeWalt DCST920 trimmer may seem intimidating at first, but with this comprehensive guide, you should feel empowered to tackle the task with ease. Proper maintenance not only enhances your trimmer’s performance but also extends its lifespan, saving you money on replacements. Remember to follow best practices, use high-quality materials, and always prioritize safety.

With your freshly loaded trimmer line, you can now tackle your yard work with renewed energy and efficiency. Happy trimming!

What type of string should I use for the DeWalt DCST920 trimmer?

To ensure optimal performance of your DeWalt DCST920 trimmer, it’s essential to use the right kind of string. The recommended line diameter is typically between 0.080 inches and 0.095 inches, depending on the type of cutting you intend to do. For regular grass trimming, a thinner line suffices, while a thicker line is more effective for tackling tougher weeds and brush.

When selecting the string type, consider using a multi-sided or square-shaped line for a cleaner cut. These types create better cutting edges compared to round strings, which can wear down more quickly. Ultimately, always refer to the manufacturer’s recommendations in your user manual for the best results.

How do I remove the old string from my DeWalt DCST920 trimmer?

Removing the old string from your DeWalt DCST920 trimmer is a straightforward process. First, ensure the trimmer is switched off, and the battery is removed for safety. Locate the spool release tabs, which are generally found on either side of the trimmer head. Gently press the tabs to release the spool and carefully pull it out from the casing.

Once the spool is out, you can unwind and discard the old string. Always check the spool for any damage or wear and replace it if necessary. After the old string is removed, you are now ready to reposition or restring the spool with fresh line, which is key to maintaining efficient trimming.

What is the correct way to string the spool of the DeWalt DCST920 trimmer?

Stringing the spool correctly is vital for the proper functioning of your DeWalt DCST920 trimmer. Begin by cutting the new replacement line to the desired length, usually around 10-12 feet. Insert one end of the line into the designated hole in the center of the spool and wind the line around the spool in the direction indicated by the arrows. Ensure that the line is wound tightly and neatly to prevent tangling.

Once you have wound the line appropriately, leave approximately 6 inches extending from the end. Secure the line in place using the notches provided on the spool and replace the spool back into the trimmer head. Make sure that the ends of the line are pulled through the eyelets until they are extended equally before reassembling the trimmer head.

How often should I replace the string on my DeWalt DCST920 trimmer?

The frequency with which you should replace the string on your DeWalt DCST920 trimmer depends on various factors, including the type of vegetation you’re cutting and how frequently you use your trimmer. If you are using the trimmer for regular grass maintenance, it may require string replacement every few weeks during the growing season. However, if you’re working in tougher environments with thick brush or weeds, you might need to replace the string more frequently.

A good rule of thumb is to monitor the string’s condition as you trim. If you notice increased difficulty in cutting or if the line has become too short or frayed, it’s time to replace it. Keeping an eye on the line will not only improve your work efficiency but also extend the overall lifespan of the trimmer.

Can I use any brand of string for my DeWalt DCST920 trimmer?

While many users may consider using various brands of string for their DeWalt DCST920 trimmer, it’s generally advisable to use the manufacturer’s recommended products or those specifically designed for the trimmer model. This ensures optimal compatibility and performance, as well as warranty considerations. Non-compatible strings can lead to problems, such as jamming or reduced cutting efficiency.

If you choose to use a different brand, ensure it meets the recommended specifications, such as the correct diameter and shape. Always check the packaging for compatibility with electric weed eaters and for the recommended diameter. Investing in high-quality string can also make a significant difference in your trimming experience.

What maintenance should I perform on my DeWalt DCST920 trimmer after restringing?

After restringing your DeWalt DCST920 trimmer, it’s essential to perform a few maintenance tasks to keep it running efficiently. Begin by cleaning the trimmer to remove any debris that may have accumulated during operation. Pay special attention to the cutting head and ensure there’s no grass or dirt obstructing the parts. A clean trimmer will perform better and prolong its lifespan.

Additionally, consider checking the other components of the trimmer, such as the battery, motor, and handles, for any signs of wear or damage. Lubricating the moving parts can also help maintain optimal performance. Regular maintenance following each restring will help prevent operational issues and keep your trimmer functioning at its best.
