Understanding Your Dewalt Electric Weed Eater
Dewalt offers several electric string trimmer models, each equipped with either a bump‑feed head or a fixed‑line head. The bump‑feed head releases new line automatically when you tap the head on the ground, while the fixed‑line head requires you to manually pull line through the eyelets. Knowing which head you have determines the exact restringing procedure.
Head Types and Line Specifications
Most Dewalt electric trimmers accept .065‑inch or .080‑inch round line. Check the owner’s manual or the label on the spool housing for the recommended diameter. Using line that is too thick can jam the feed mechanism; line that is too thin may break prematurely under load.
Bump‑feed heads typically have a single spool that holds 15‑20 feet of line. Fixed‑line heads often use a dual‑line configuration with two separate eyelets, each requiring its own length of line. Both designs are engineered for easy user service, but the threading path differs slightly.
Tools and Materials Needed
- Replacement trimmer line (correct diameter and length)
- Scissors or a utility knife for cutting line
- Work gloves to protect hands from sharp edges
- Safety glasses
- Flat‑head screwdriver (only if your model uses a retaining screw)
- Clean cloth for wiping debris
Having these items on hand before you start eliminates interruptions and ensures a smooth workflow.
Safety Precautions
Before any maintenance, disconnect the trimmer from its power source. For corded models, unplug the unit; for battery‑powered models, remove the battery pack. Wear safety glasses to shield your eyes from line fragments, and gloves to prevent cuts. Keep the work area clear of children and pets. Never attempt to restring the trimmer while it is plugged in or the battery is installed.
Step‑by‑Step Restringing Guide
The following ordered list covers the universal steps that apply to both head types. After the list, you will find head‑specific details. (See Also:Who Carries Weed Eater Brand)
- Power off and disconnect – Unplug the cord or remove the battery.
- Remove the spool housing – Press the release tabs or unscrew the retaining cap, then lift the housing off the trimmer head.
- Take out the old spool – Pull the spent spool straight out. Discard any remaining line fragments.
- Clean the head – Wipe away grass, dirt, and debris from the housing and the drive shaft.
- Prepare the new line – Cut two equal lengths (typically 10‑12 ft each) for bump‑feed; cut a single length (about 20 ft) for fixed‑line heads.
- Thread the line – Follow the head‑specific threading path described in the next sections.
- Wind the line onto the spool – Keep tension even and wind in the direction indicated by arrows on the spool.
- Reinstall the spool – Place the wound spool back into the housing, ensuring the line feeds through the eyelets.
- Reattach the housing – Snap or screw the housing back onto the trimmer head.
- Test the feed – Reconnect power, start the trimmer, and tap the head (bump‑feed) or pull the line (fixed‑line) to verify proper operation.
Detailed Walkthrough for Bump Feed Head
Bump‑feed heads are the most common on Dewalt electric trimmers. The spool usually has a single winding channel with an arrow showing the winding direction.
- Locate the small anchor hole on the spool flange. Insert one end of the first line piece about 1 inch into the hole.
- Wind the line tightly and evenly around the spool, following the arrow. Keep the line flat; overlapping causes jams.
- Leave roughly 6 inches of line free at the end. Insert this tail into the opposite anchor hole or the notch provided.
- Repeat the process with the second line piece on the other side of the spool if your model uses dual‑line bump feed.
- Place the spool into the housing, guiding the free ends through the eyelets on the housing cover.
- Snap the cover back on, making sure the line is not pinched.
After re‑assembly, start the trimmer and gently tap the head on grass. The centrifugal force should release a short length of line each tap.
Detailed Walkthrough for Fixed Line Head
Fixed‑line heads require manual threading but offer precise line length control.
- Cut a single length of line about 20 ft long.
- Fold the line in half to find the midpoint. Insert the midpoint into the central anchor hole of the spool.
- Wind both halves simultaneously in opposite directions, keeping each half in its own channel. Follow the directional arrows.
- Leave about 6 inches of each tail protruding from the spool.
- Thread each tail through its respective eyelet on the housing cover.
- Reinstall the spool and snap the cover shut.
When the line wears down, pull the desired length through the eyelets by hand before the next use.
Comparison Table: Bump Feed vs Fixed Line
| Feature | Bump Feed Head | Fixed Line Head |
|---|---|---|
| Line Release | Automatic on tap | Manual pull |
| Ease of Restringing | Moderate (single spool) | Easy (single line) |
| Line Consumption | Higher (continuous feed) | Lower (controlled length) |
| Best For | Large areas, heavy growth | Precision trimming, edging |
| Typical Line Diameter | .065‑.080 in | .065‑.080 in |
Choose the head type that matches your typical workload. Bump feed excels in open fields, while fixed line gives you exact control for garden beds.
Tips for Optimal Performance
- Use only Dewalt‑approved or high‑quality third‑party line that matches the recommended diameter.
- Store spare line in a cool, dry place to prevent brittleness.
- Wind the line under slight tension; loose winding leads to snags.
- Periodically inspect the eyelets for wear; replace the housing if the plastic is cracked.
- After each use, wipe the head clean to prevent grass buildup that can impede line feed.
Common Mistakes and How to Avoid Them
- Using the wrong line diameter – Always verify the spec label; mismatched line causes jams or breakage.
- Over‑winding the spool – Leave the recommended tail length; excess line can bind the feed mechanism.
- Cross‑threading the line – Follow the arrows; winding opposite the indicated direction prevents proper release.
- Forgetting to disconnect power – This is a safety hazard and can damage the motor if the head spins unexpectedly.
- Neglecting to clean the head – Debris buildup restricts line movement and accelerates wear.
Maintenance After Restringing
Once the new line is installed, run the trimmer for a minute at low speed to seat the line. Check that the line feeds smoothly and that there is no vibration from an unbalanced spool. Lubricate the drive shaft with a light machine oil if the manufacturer recommends it. Store the trimmer in a dry location, and recharge or replace the battery as needed to keep the tool ready for the next job.
Troubleshooting Common Issues
- Line won’t feed – Verify that the line is wound in the correct direction and that the eyelets are clear. Re‑wind if necessary.
- Line breaks immediately – The line may be too thin for the load, or the spool may be over‑wound. Use the proper diameter and leave adequate tail length.
- Excessive vibration – An unevenly wound spool creates imbalance. Remove the spool and re‑wind with even tension.
- Head does not spin – Ensure the housing is fully seated and the retaining tabs are locked. Check for a seized drive shaft.
Frequently Asked Questions
What line diameter should I use for my Dewalt electric weed eater?
Most Dewalt electric models accept .065‑inch or .080‑inch round line. Consult the label on the spool housing or the owner’s manual for the exact specification. (See Also:How To Hold A Stihl Weed Eater)
How often should I restring the trimmer?
Restring whenever the line becomes too short to cut effectively, typically after 30‑60 minutes of heavy use. Frequent users may restring weekly.
Can I use any brand of trimmer line?
You can use third‑party line as long as it matches the recommended diameter and is rated for electric trimmers. Low‑quality line may fray or melt.
Why does my bump feed head not release line when I tap it?
Common causes include line wound in the wrong direction, debris blocking the eyelets, or a worn spring inside the head. Clean the head and re‑wind following the arrow indicators.
How much line should I leave on a fixed‑line head?
Leave about 6 inches of each tail protruding from the eyelets. This provides enough length for several cuts before you need to pull more line through. (See Also:How To Use A Weed Eater For Edging)
