How to Replace Trimmer Line on Your Black and Decker String Trimmer: A Step-by-Step Guide
Keeping your Black and Decker string trimmer in optimal working condition is crucial for maintaining a tidy and attractive yard. One of the most frequent maintenance tasks you’ll encounter is replacing the trimmer line. Whether your line has completely run out, snapped, or become hopelessly tangled within the spool head, this guide will equip you with the knowledge to tackle the job with confidence.
We’ll cover everything from identifying the correct line to the actual replacement process for various Black and Decker models. Understanding the nuances of your specific trimmer can make this task even smoother. So, grab your tools, and let’s get your trimmer humming again!
Understanding Your Black and Decker Trimmer Head
Before we dive into the replacement process, it’s essential to understand the type of spool head your Black and Decker trimmer utilizes. Most Black and Decker trimmers use an automatic feed system, often referred to as a “bump feed” or “auto-feed” system. This means that as you bump the trimmer head against the ground, a small amount of new line is automatically fed out. However, sometimes the mechanism can get jammed, or you might simply need to manually refill it. (See Also: how to reload ego string trimmer)
There are generally two main types of spool heads you’ll encounter:
- Single-line feed: These heads use one continuous strand of trimmer line.
- Dual-line feed: These heads use two strands of trimmer line, which often provides a more powerful and efficient cut.
Identifying your specific model number can be incredibly helpful. You can usually find this on a label on the trimmer itself. Once you know your model, you can often find model-specific instructions or diagrams online, which can be invaluable.
What You’ll Need to Replace the Trimmer Line
Gathering the right supplies before you start will make the process much more efficient. Here’s what you’ll typically need:
- New Trimmer Line: This is the most critical item. Ensure you purchase the correct type and diameter of line for your Black and Decker trimmer. Using the wrong size can damage your trimmer. Check your owner’s manual or the label on the trimmer head for specifications. Common diameters are 0.065″, 0.080″, and 0.095″.
- Replacement Spool: Many Black and Decker trimmers come with pre-wound replacement spools. These are the easiest to use as they are already loaded. If your trimmer uses a manual refill system, you’ll just need the line.
- Gloves: Protect your hands from sharp edges and debris.
- Safety Glasses: Essential for protecting your eyes from flying debris.
- Pliers (optional but helpful): Can be used to help pull out old line or secure new line.
- Wire Cutters or Scissors: To trim excess line.
- A Flathead Screwdriver or a Small Tool (sometimes): For prying open certain spool covers.
- A Clean Workspace: A workbench or a clean patch of ground will make it easier to manage small parts.
Step-by-Step Guide: Replacing the Trimmer Line (using a Pre-Wound Spool)
This is the most common and easiest method for Black and Decker trimmers. Many of their models are designed for quick spool changes. (See Also: how to trim mustache with trimmer)
- Ensure the Trimmer is Off and Unplugged: Safety first! Make absolutely certain the trimmer is turned off and, if it’s an electric model, unplugged from the power source. For gas trimmers, ensure the spark plug wire is disconnected to prevent accidental starting.
- Locate the Spool Head: The spool head is the part at the bottom of the trimmer shaft that houses the line and spins when the trimmer is active.
- Remove the Old Spool Cover: Most Black and Decker spool heads have a cover that needs to be removed to access the spool. Look for tabs or a central knob. You might need to press release tabs on the sides of the housing simultaneously while pulling the cover upwards. Some models may require a flathead screwdriver to gently pry it open if it’s stuck.
- Remove the Old Spool: Once the cover is off, you should see the old spool. It might be in one piece or broken. Simply lift the old spool out. If there’s any remaining tangled line, carefully remove it.
- Install the New Spool: Take your new, pre-wound replacement spool. Align the slots or guides on the spool with the corresponding parts on the trimmer head. The line should feed out through the eyelets at the bottom of the spool head.
- Feed the Line Through the Eyelets: Ensure the ends of the new line are properly threaded through the eyelets (small holes) on the trimmer head. If it’s a dual-line spool, make sure both lines are threaded through their respective eyelets.
- Replace the Spool Cover: Carefully place the spool cover back onto the trimmer head. Ensure it clicks securely into place. You should feel or hear it snap shut. Make sure it’s properly seated all the way around.
- Test the Line Feed: Once the cover is secured, you can test the automatic feed. If it’s an electric trimmer, plug it back in. If it’s a gas trimmer, reconnect the spark plug wire. Briefly turn the trimmer on and let it run for a few seconds. You might need to gently bump the spool head against a hard surface (like the ground) to help the line feed out initially.
- Trim Excess Line (if necessary): If too much line has fed out, you can trim it to the appropriate length (usually around 6-8 inches) with wire cutters or scissors to prevent it from getting tangled or hitting the guard.
Step-by-Step Guide: Manually Re-Spooling Your Black and Decker Trimmer Head
If you prefer to wind your own line or can’t find a pre-wound spool for your model, manual re-spooling is the way to go. This method requires a bit more patience but can be more economical.
- Safety First: As always, ensure the trimmer is off and unplugged (or spark plug disconnected for gas models).
- Disassemble the Spool Head: Remove the spool cover as described in steps 2 and 3 of the previous method. You will likely need to remove the spool itself as well. Some spool heads have a central screw or clip that needs to be removed to detach the spool from the spindle.
- Remove All Old Line: Carefully remove any remaining old trimmer line from the spool and the trimmer head. It’s crucial to start with a clean slate.
- Prepare the New Line: Cut a length of your new trimmer line. The exact length will depend on your trimmer head, but a good starting point is usually around 15-25 feet. Consult your owner’s manual for specific recommendations.
- Secure One End of the Line: Find the small notch or slot on the side of the empty spool. Insert one end of the new trimmer line into this notch and secure it firmly. This prevents the line from unraveling as you wind.
- Wind the Line onto the Spool: This is the most critical part. You need to wind the line in the same direction as it was originally wound. Look for arrows on the spool or the trimmer head that indicate the winding direction.
- Wind Tightly and Evenly: Begin winding the line onto the spool, ensuring it is taut and neat. Avoid overlapping the line or winding it too loosely, as this can cause tangles and feeding issues. If you have a dual-line spool, you’ll need to wind each line through its respective channel on the spool, ensuring they are kept separate.
- Secure the Other End: Once you have wound the desired amount of line, secure the other end in the second notch or slot on the spool. This keeps the line from unraveling when you assemble the head.
- Reassemble the Spool Head: Carefully place the wound spool back onto the trimmer head spindle. Ensure the line is fed through the eyelets correctly. Reattach any retaining clips or screws.
- Replace the Spool Cover: Put the spool cover back on and ensure it clicks securely into place, as described in step 7 of the previous method.
- Test the Feed: Plug in or reconnect the spark plug wire and test the trimmer’s functionality. You may need to bump the head to feed the initial length of line.
Tips for Successful Trimmer Line Replacement
Even with clear instructions, a few extra tips can make the process even smoother and prevent common headaches:
- Use the Right Line: We can’t stress this enough. Using the wrong diameter or type of line (e.g., a square-edged line in a round-edged trimmer) can lead to poor performance, damage to the trimmer head, and premature wear. Always check your owner’s manual for the recommended line specifications.
- Keep Spare Spools Handy: For convenience, especially during peak gardening season, keep a few pre-wound spools on hand. This allows for incredibly fast replacements when you’re in the middle of a job.
- Store Line Properly: Trimmer line can become brittle if exposed to extreme heat or sunlight. Store spare line in a cool, dry place. Some people even recommend soaking new line in water for a few hours before use to make it more flexible and durable.
- Clean the Spool Head Regularly: After replacing the line, it’s a good time to clean out any grass clippings, dirt, or debris from the spool head. This helps prevent jams and ensures the auto-feed mechanism works correctly.
- Check for Damage: While you have the spool head apart, inspect it for any cracks or damage. If the housing or internal mechanisms are damaged, it might be time to consider replacing the entire trimmer head unit.
- Listen to Your Trimmer: If your trimmer starts making unusual noises or struggles to feed line, it’s often a sign that the line is tangled, the spool is incorrectly seated, or the mechanism needs cleaning.
- Don’t Overfill: When manually re-spooling, avoid overfilling the spool. Too much line can prevent the cover from closing properly or cause tangles.
- Wind in the Correct Direction: This is crucial for manual re-spooling. Winding the wrong way will lead to immediate feeding problems.
Troubleshooting Common Trimmer Line Issues
Even with careful replacement, you might encounter some common problems. Here’s how to address them:
Trimmer Line Not Feeding
- Check the Spool: Ensure the spool is correctly seated and the cover is snapped on securely.
- Tangled Line: The line may be tangled on the spool or within the head. Disassemble the head and carefully untangle or remove the offending line.
- Line is Too Short: For manual feed systems, you might need to manually feed more line out. For auto-feed, bump the trimmer head against the ground.
- Debris in the Mechanism: Clean out any grass clippings or dirt from the spool area and the feed mechanism.
- Wrong Line Diameter: If you recently switched line types, ensure it’s the correct diameter for your trimmer.
Trimmer Line Snapping Frequently
- Line is Old or Brittle: Replace the line with fresh material.
- Cutting Through Thick Weeds/Hard Objects: Avoid hitting fences, rocks, or thick woody stems, which can break the line.
- Wrong Line Type: Some lines are designed for lighter duty. Consider a more durable line if you’re cutting through tough vegetation.
- Trimmer Head Guard is Too Close: Ensure the guard isn’t rubbing against the line, causing friction and breakage.
Trimmer Head Not Spinning or Spinning Weakly
- Motor Issue: This could indicate a problem with the trimmer’s motor, especially if it’s affecting both line feed and rotation.
- Binding: Something might be physically binding the spool head. Check for debris or damage.
- Low Power (Electric/Battery): Ensure your battery is fully charged or the trimmer is properly connected to power.
- Engine Issues (Gas): For gas trimmers, this could be a sign of engine trouble or a drive shaft issue.
When to Consider Replacing the Entire Trimmer Head
While replacing the line is a common maintenance task, there are times when the entire spool head unit might need replacing: (See Also: how to use a beard trimmer)
- Cracked or Damaged Housing: If the plastic housing of the spool head is cracked, it won’t hold the spool correctly and can be a safety hazard.
- Stripped Threads: If the threads where the spool cover attaches are stripped, you won’t be able to secure it properly.
- Damaged Internal Mechanism: If the gears or spring mechanism within the head is broken, the auto-feed will likely fail.
- Persistent Feeding Issues: If you’ve tried everything and the line still won’t feed consistently, the head itself might be faulty.
Replacement trimmer heads are usually available from the manufacturer or at hardware stores. The process for replacing the entire head often involves unscrewing the old unit from the trimmer shaft and screwing on the new one. Always refer to your trimmer’s manual for specific instructions on head replacement.
