Understanding Your Dewalt Weed Eater

Dewalt offers several trimmer models — 20V MAX, 60V MAX, and the newer 120V MAX series — each equipped with a slightly different head design. Most current models use a bump‑feed or automatic‑feed head that accepts a spool of .080‑inch or .095‑inch line. Knowing which head you have determines the exact threading path and the amount of line you’ll need. Check the model number on the motor housing or the owner’s manual; the head type is usually listed as “bump feed,” “auto feed,” or “fixed line.” This information will guide you through the rest of the process.

Tools and Materials You’ll Need

• Replacement trimmer line (matching diameter and length recommended for your model)
• Protective gloves
• Safety glasses
• Small flat‑head screwdriver (for heads with a retaining screw)
• Scissors or a utility knife
• Clean rag

Having everything within arm’s reach prevents interruptions and keeps the workspace tidy.

Safety Precautions Before You Start

Before you touch the trimmer, make sure the battery is removed (or the unit is unplugged for corded models). Wear safety glasses to protect your eyes from any stray line fragments, and gloves to guard against sharp edges on the spool. Work on a stable surface — preferably a workbench or a clean patch of grass — so the trimmer cannot roll away. Keep children and pets at a safe distance while you’re handling the cutting head.

Removing the Old Trimmer Line

1. Turn the trimmer upside down so the head faces upward.
2. If your model has a retaining screw, loosen it with the flat‑head screwdriver and set the screw aside.
3. Pull the spool out of the head housing. Some heads have a release tab; press it and lift the spool free.
4. Unwind any remaining line from the spool. Discard the old line responsibly.
5. Wipe the spool and head interior with a clean rag to remove grass debris and dust.

Inspect the spool for cracks or excessive wear. A damaged spool should be replaced along with the line.

Choosing the Right Replacement Line

Line diameter matters. Most Dewalt 20V and 60V trimmers perform best with .080‑inch line, while heavier‑duty 120V models often use .095‑inch. Using a line that’s too thick can jam the feed mechanism; too thin and it will break prematurely. Look for “commercial‑grade” or “premium” line that resists welding and UV degradation. Purchase a spool that provides at least 20 feet of line — this gives you enough length for several re‑strings without frequent trips to the store.

Step‑by‑Step: How to String a Dewalt Weed Eater?

Follow these numbered steps carefully. The process is essentially the same for bump‑feed and auto‑feed heads, with only minor variations noted. (See Also:How To Recoil A Stihl Weed Eater)

1. Prepare the new line. Cut a length of line roughly 20 feet (or the length specified in your manual). If the line is pre‑spooled, skip to step 4.
2. Find the anchor holes. Most Dewalt spools have two small holes opposite each other. These are the entry points for the line.
3. Thread the first end. Insert one end of the line into the first anchor hole, pulling it through until about 6 inches remain outside the spool.
4. Wind the line. Hold the spool steady and wind the line tightly and evenly in the direction indicated by the arrow on the spool (usually clockwise). Keep tension consistent to avoid loose loops.
5. Leave a tail. After winding, leave another 6‑inch tail protruding from the second anchor hole.
6. Secure the tails. Some spools have a small notch or slot near each anchor hole; tuck the tails into these slots to prevent them from unraveling.
7. Reinstall the spool. Place the spool back into the head housing, aligning any tabs or grooves. If there is a retaining screw, tighten it snugly — do not overtighten.
8. Feed the line. For bump‑feed heads, tap the head gently on the ground while the motor runs at low speed to advance the line. For auto‑feed heads, simply start the trimmer; the mechanism will pull the correct length.
9. Trim excess. If the line extends far beyond the cutting radius, cut it back to the recommended length (usually 2‑3 inches beyond the head).
10. Test cut. Run the trimmer on a patch of grass. The line should feed smoothly and cut cleanly. Adjust if you notice uneven feeding.

Congratulations — you’ve just completed the full procedure for How to String a Dewalt Weed Eater? and your trimmer is ready for action.

Common Mistakes to Avoid

• Over‑winding the spool. Too much line creates friction and can cause the feed to stall.
• Using the wrong diameter. Mismatched line leads to jams or premature breakage.
• Forgetting to secure the tails. Loose tails unravel during operation, leaving you with a half‑spooled head.
• Skipping the cleaning step. Debris inside the head interferes with the feed mechanism.
• Overtightening the retaining screw. This can crack the spool housing and make future removal difficult.

Maintenance Tips for Longer Line Life

Regular upkeep extends both line and head longevity. After each use, brush off grass clippings from the head and spool. Store the trimmer in a dry, shaded area — UV exposure makes line brittle. Periodically inspect the feed spring (on bump‑feed models) for corrosion; a light coat of silicone spray keeps it moving freely. Replace the line at the first sign of fraying or when the cutting edge becomes rounded. Keeping a spare spool on hand means you’ll never be caught mid‑job with a dull line.

Comparison of Dewalt Trimmer Heads

Choose the head that matches your workload. Bump‑feed heads are simple and reliable; auto‑feed heads reduce downtime but have more moving parts that may require occasional lubrication.

Troubleshooting Feed Issues

If the line won’t advance, check these common culprits:

• Line wound backward. Re‑wind following the arrow direction.
• Spool not seated fully. Remove and reinstall, ensuring tabs lock.
• Debris in the feed eyelet. Clean with compressed air or a soft brush.
• Weak feed spring (bump feed). Replace the spring if it feels loose.
• Battery low. Insufficient power can stall the auto‑feed motor.

Most issues resolve with a quick inspection and re‑string. Persistent problems may indicate a worn head assembly that needs replacement.

Frequently Asked Questions

How often should I replace the trimmer line?

Replace the line whenever it shows visible wear, becomes brittle, or fails to cut cleanly. For average residential use, this is typically every 2‑3 months. (See Also:How To Remove Head From Murray Weed Eater)

Can I use any brand of line in my Dewalt trimmer?

Yes, as long as the diameter matches the specification for your model. Premium brands often last longer and resist welding better than budget options.

What length of line should I cut for a fresh spool?

Most Dewalt spools require about 20 feet of line. Consult your owner’s manual for the exact figure; cutting a little extra gives you margin for error.

Why does my line keep breaking at the eyelet?

Sharp edges on the eyelet or a mis‑aligned spool can shear the line. Inspect the eyelet for burrs and smooth them with a fine file if needed.

Is it necessary to remove the battery before re‑stringing?

Absolutely. Removing the battery eliminates any chance of accidental start‑up, protecting both you and the tool. (See Also:How To Start A Gas Weed Eater)
