How to Replace the Line on Your Black and Decker Trimmer: A Step-by-Step Guide
Maintaining a well-groomed lawn and garden often involves the use of a string trimmer, also known as a weed whacker or weed eater. Black and Decker trimmers are a popular choice for homeowners due to their reliability and ease of use. However, one of the most common maintenance tasks is replacing the trimmer line. When the line runs out or breaks frequently, it’s time to reload the spool. This comprehensive guide will walk you through the process of replacing the line on your Black and Decker trimmer, ensuring you can keep your yard looking its best.
Understanding Your Black and Decker Trimmer
Before we dive into the step-by-step instructions, it’s important to understand the basic components of your Black and Decker trimmer and the different types of spools it might use. Familiarizing yourself with these elements will make the replacement process smoother and prevent potential issues.
Key Components:
* **Motor Housing:** Contains the motor that powers the trimmer.
* **Shaft:** Connects the motor housing to the trimmer head.
* **Trimmer Head:** The part of the trimmer that holds the spool and dispenses the line.
* **Spool:** A plastic or metal cylinder that holds the trimmer line.
* **Spool Cap:** A cover that secures the spool within the trimmer head.
* **Line:** The nylon string that cuts the grass and weeds.
* **Line Feed Mechanism:** The system that advances the line, which can be automatic or manual.
Types of Spools:
Black and Decker trimmers typically use one of two types of spools:
* **Single-Line Spool:** Uses a single strand of trimmer line.
* **Dual-Line Spool:** Uses two strands of trimmer line for increased cutting power.
Knowing which type of spool your trimmer uses is crucial for selecting the correct replacement line. This information is usually found in your trimmer’s user manual or on a label on the trimmer itself.
Preparing for the Line Replacement
Before you begin, gather the necessary tools and materials and ensure you have a safe workspace. This preparation will streamline the process and minimize potential hazards.
Tools and Materials:
* **Replacement Trimmer Line:** Purchase the correct type and diameter of trimmer line recommended for your specific Black and Decker model. This information is usually in the user manual. Using the wrong type of line can damage the trimmer head or affect its performance. Common line diameters range from 0.065 inches to 0.080 inches.
* **Scissors or Wire Cutters:** To cut the trimmer line to the correct length.
* **Gloves (Optional):** To protect your hands from dirt and potential cuts.
* **User Manual:** Refer to your trimmer’s user manual for specific instructions and diagrams related to your model. The manual can be invaluable in troubleshooting any issues you might encounter.
Safety Precautions:
* **Disconnect the Power:** Before performing any maintenance, always disconnect the trimmer from the power source. If it’s a corded model, unplug it from the outlet. If it’s a cordless model, remove the battery pack. This is the most important safety precaution to prevent accidental starting of the trimmer.
* **Wear Safety Glasses:** Although optional for this specific task, wearing safety glasses is generally a good practice when working with power tools, as debris can sometimes fly up.
* **Work in a Well-Lit Area:** Ensure you have adequate lighting to see what you’re doing clearly. This will help you avoid mistakes and potential injuries.
* **Keep Children and Pets Away:** Ensure that children and pets are kept at a safe distance from the work area.
Step-by-Step Instructions for Replacing the Trimmer Line
Now that you’re prepared, let’s walk through the process of replacing the trimmer line. These instructions are generally applicable to most Black and Decker trimmers, but always refer to your user manual for model-specific details.
Step 1: Remove the Spool Cap
The first step is to remove the spool cap from the trimmer head. The method for removing the cap varies slightly depending on the model, but here are some common methods:
* **Push-Button Release:** Some models have a button or two on the trimmer head that you need to press simultaneously to release the cap. Press the button(s) and gently pull the cap away from the trimmer head.
* **Twist-and-Pull:** Other models require you to twist the cap counterclockwise to unlock it and then pull it off. Look for arrows or markings on the cap that indicate the direction of the twist.
* **Lever Release:** Some older models might have a small lever that you need to lift or depress to release the cap.
If you’re unsure how to remove the cap, consult your user manual for specific instructions.
Step 2: Remove the Old Spool
Once the spool cap is removed, you can take out the old spool. If there’s any remaining trimmer line on the spool, discard it. Inspect the spool and the trimmer head for any debris or damage. Clean them with a brush or cloth if necessary. Make sure that no pieces of the old line are lodged anywhere, as they may affect the spool’s movement.
Step 3: Prepare the New Trimmer Line
Now it’s time to prepare the new trimmer line. The length of the line you need depends on the size of your spool and the type of trimmer. Again, refer to your user manual for the recommended length. If you don’t have the manual, a good starting point is about 10-20 feet of line.
Cut two pieces of line if you have a dual line spool, or one piece if you have a single line spool. It’s better to err on the side of having too much line than too little.
Step 4: Wind the New Trimmer Line onto the Spool
This is the most crucial step, and it’s important to wind the line correctly to avoid tangling and ensure smooth feeding. There are two primary methods for winding the line, depending on the type of spool:
* **Spools with Line Guides:** Most Black and Decker spools have line guides or arrows that indicate the direction in which to wind the line. Follow these guides carefully.
* Find the hole on the spool where you will insert the end of the line.
* Insert the end of the line into the hole and wind the line tightly and evenly around the spool in the direction indicated by the arrows.
* Overlap the line as little as possible. Overlapping can cause the line to jam and break.
* Leave a few inches of line unwound at the end to thread through the eyelets in the spool housing.
* If you are using a dual-line spool, make sure that each line is wound on its respective side of the spool.
* **Spools without Line Guides:** If your spool doesn’t have line guides, follow these general steps:
* Find the center of the line and place it against the center of the spool.
* Hold the line in place and begin winding it tightly and evenly around the spool.
* Make sure to wind the line in the same direction on both sides of the spool.
* Overlap the line as little as possible.
* Leave a few inches of line unwound at the end to thread through the eyelets in the spool housing.
**Important Tips for Winding the Line:**
* **Tension:** Keep the line taut as you wind it onto the spool. This will prevent it from becoming loose and tangled.
* **Evenness:** Wind the line evenly across the spool to ensure it feeds smoothly.
* **Overlapping:** Avoid overlapping the line as much as possible, as this can cause it to jam.
* **Direction:** Always wind the line in the direction indicated by the arrows on the spool or in your user manual.
* **Do not overfill:** Do not put too much line on the spool. It should be snug, but not bulging.
Step 5: Secure the Line in the Spool Housing
After winding the line onto the spool, you need to secure the ends of the line in the spool housing. Most Black and Decker trimmers have small eyelets or slots on the edge of the spool housing that you can thread the line through. Follow these steps:
* Locate the eyelets or slots on the edge of the spool housing.
* Thread the ends of the line through the eyelets or slots.
* Make sure the line is securely held in place.
This will prevent the line from unwinding from the spool before you put the spool into the trimmer head.
Step 6: Reinstall the Spool
Now it’s time to reinstall the spool into the trimmer head. Follow these steps:
* Align the spool with the trimmer head.
* Insert the spool into the trimmer head, making sure it sits properly in place.
* Make sure the ends of the line are still threaded through the eyelets in the spool housing.
Step 7: Reattach the Spool Cap
Finally, reattach the spool cap to the trimmer head. Depending on the model, you may need to:
* **Push the cap back into place until it clicks.** This indicates that it is securely fastened.
* **Twist the cap clockwise to lock it in place.** Look for arrows or markings on the cap that indicate the direction of the twist.
* **Engage the lever.**
Make sure the cap is securely fastened to prevent the spool from coming loose during operation.
Step 8: Test the Trimmer
Before you start using the trimmer, it’s a good idea to test it to make sure the line is feeding correctly. Follow these steps:
* Reconnect the trimmer to the power source (plug it in or reinsert the battery).
* Hold the trimmer away from your body and any obstacles.
* Turn the trimmer on.
* Tap the trimmer head lightly on the ground. This should activate the line feed mechanism and advance the line.
* If the line doesn’t feed, turn off the trimmer and check the spool to make sure the line is wound correctly and that there are no jams.
Troubleshooting Common Issues
Even with careful attention to detail, you might encounter some issues during the line replacement process. Here are some common problems and how to troubleshoot them:
* **Line Not Feeding:**
* **Cause:** Incorrect winding, tangled line, empty spool, or faulty line feed mechanism.
* **Solution:** Rewind the line correctly, remove any tangles, replace the spool, or consult a repair technician for the line feed mechanism.
* **Line Breaking Frequently:**
* **Cause:** Using the wrong type of line, cutting against hard surfaces, or old and brittle line.
* **Solution:** Use the correct type of line, avoid cutting against hard surfaces, and replace the line regularly.
* **Spool Cap Not Staying On:**
* **Cause:** Damaged spool cap, worn-out locking mechanism, or incorrect installation.
* **Solution:** Replace the spool cap, clean the locking mechanism, or reinstall the cap correctly.
* **Trimmer Not Starting:**
* **Cause:** No power, faulty switch, or motor problems.
* **Solution:** Check the power source, test the switch, or consult a repair technician for motor issues.
