How to String a DeWalt Weed Eater: Quick Answer
To string a DeWalt weed eater, remove the spool head by twisting it counterclockwise or pressing the release button, clear out old line debris, measure and cut 17 to 20 feet of new trimmer line (depending on your model), wind it tightly around the spool following the directional arrows, leave 6 to 8 inches of line on each side, thread the ends through the eyelets, and reinstall the spool head. Most DeWalt models use a manual two-line spool system, though some newer units feature semi-automatic or automatic feed mechanisms.
Understanding Your DeWalt Trimmer Head
Before you attempt to string your DeWalt weed eater, it’s important to familiarize yourself with the main components of the trimmer head. The spool is the central cylindrical part that holds and dispenses the trimmer line. Around the spool, you’ll find the spool housing, which protects the line and guides it toward the eyelets, the small holes or slots where the line exits the head.
DeWalt offers several spool types across its weed eater lineup. Manual spools require you to wind the line by hand and are the most common type. Semi-automatic spools advance line as you tap the head on the ground, reducing the need for constant manual winding. Automatic spools continuously feed line as the trimmer operates, though these are less common on entry-level models.
To identify which type you have, consult your product manual or check the DeWalt website using your model number, which is typically stamped on the trimmer’s motor housing or battery platform. The manual will also specify the correct trimmer line gauge (usually .065 or .080 inches) and the recommended line length for your specific model.
Gathering Materials and Tools
Before starting, collect the following items:
- Trimmer line: DeWalt trimmer line or a compatible brand matching your model’s gauge specification
- Scissors or line cutter: For cutting the line to length
- Measuring tape: To verify line length
- Needle-nose pliers (optional): Helpful if the spool head is stuck or tight
- Small brush or compressed air: For cleaning debris from the spool
- Your DeWalt trimmer manual: For model-specific guidance
Most DeWalt models require 17 to 20 feet of trimmer line, but check your manual for the exact specification. Buying trimmer line in bulk spools or pre-cut lengths saves money and ensures you always have spare line on hand.
Removing the Spool Head Safely
Safety first: Always disconnect the battery or unplug your trimmer before removing the spool head. This prevents accidental line feeding or motor engagement.
Most DeWalt weed eaters use one of two removal methods:
- Twist-off heads: Look for a notch or grip area on the spool head cap. Grip the head firmly and twist counterclockwise. Some models may require you to hold the spool stationary with one hand while twisting the cap with the other.
- Button-release heads: Press or hold a small button on the side of the head cap while gently pulling or twisting. The cap should separate easily.
If the head is stuck, apply a small amount of penetrating oil around the seam and let it sit for a few minutes. Use needle-nose pliers wrapped in a cloth to avoid stripping the grip area, then gently twist. Never force the head, as this can crack the plastic housing.

Removing Old Line and Cleaning the Spool
Once the spool head is off, you’ll likely find fragments of old line or dried line stuck to the spool grooves. Carefully pick out any visible line remnants using your fingers or needle-nose pliers. Use a small brush or compressed air to dislodge stubborn debris or dust inside the spool chamber.
Inspect the spool for cracks or damage. If you notice deep cracks, the spool may need replacement. Check the eyelets (the small holes where line exits) to ensure they’re clear of debris or damage. A blocked eyelet will prevent line from feeding properly. When planning workspace deployment, consider the engineering criteria outlined in our dyson v8 cyclone vs bissell featherweight stick guide.
Wipe the spool clean with a dry cloth. A clean spool ensures smooth line winding and prevents old line fragments from tangling with new line.
Measuring, Cutting, and Winding New Line
This is the most critical step. Accurate measurement and proper winding technique determine whether your trimmer will function correctly. For additional operational safety benchmarks, see our published testing notes on bissell crosswave hydrosteam vs shark stainforce.
Step 1: Cut the line to length. Measure out 17 to 20 feet of trimmer line (or the length specified in your manual) and cut it cleanly with scissors. If cutting a pre-wound spool, make sure the line is straight and not kinked.
Step 2: Locate the directional arrow on the spool. Most DeWalt spools have an arrow molded into the plastic indicating the correct winding direction. This is crucial, winding in the wrong direction prevents line from feeding.
Step 3: Position the line. Find the small slot or notch near the edge of the spool where you’ll begin winding. Insert one end of the trimmer line into this slot and hold it firmly.
Step 4: Wind the line tightly. Wind the line around the spool in the direction indicated by the arrow. Keep tension on the line as you wind to ensure it sits flat and doesn’t overlap itself. Wind in a tight, orderly spiral, working from the center outward or following the spool’s groove pattern.
Step 5: Leave proper slack. Wind until 6 to 8 inches of line remain unwound on each side of the spool. This slack allows the line to feed through the eyelets and prevents over-tensioning, which can jam the mechanism.
Common winding mistake: Over-winding (leaving too little slack) is the #1 reason trimmer heads jam. Under-winding wastes line and may cause feeding issues. Aim for the 6 to 8 inch target consistently.
Threading Line and Reinstalling the Spool
With the line wound, you’re ready to thread it through the eyelets and reassemble the head.
Step 1: Thread the line ends. Take one of the slack line ends and thread it through one of the two eyelets on the spool head. Then thread the second line end through the second eyelet. Make sure the line is fully seated in each eyelet slot.
Step 2: Secure the line (if required). Some DeWalt models have small notches or clips that hold the line ends in place during reassembly. Check your manual to see if your model requires this. If so, position the line ends in these notches before reattaching the head.
Step 3: Reinstall the spool head. Align the spool inside the head cap and twist clockwise (or push, depending on your model’s design) until the cap is snug. Don’t over-tighten, as this can crack the plastic. The head should be secure but not require excessive force.
Step 4: Pull the line taut. Once reassembled, gently pull both line ends to ensure they feed smoothly through the eyelets and extend equally on both sides. Trim any excess line protruding beyond the eyelet to about 1 to 2 inches per side.
Testing and Troubleshooting
After reassembly, reconnect the battery and test the trimmer at low speed (if your model has speed control). The line should feed smoothly from both sides. Tap the head gently on the ground if your model has a semi-automatic feed system.
If the line doesn’t feed: The line may be wound in the wrong direction, over-wound, or jammed in the eyelets. Remove the head, unwind slightly to reduce tension, ensure proper winding direction, and retry.
If the line breaks quickly: The line gauge may be incorrect, or the eyelets may be damaged. Verify you’re using the correct gauge for your model and inspect the eyelets for sharp edges or cracks.
If line tangles inside the head: Old line debris may still be trapped. Disassemble again and clean thoroughly with compressed air.
Model-Specific Variations
DeWalt’s weed eater lineup includes several models, and minor design differences can affect the stringing process. Entry-level models (such as the DCST920) typically use simple manual spools identical to the process described above. Mid-range models may feature semi-automatic or bump-feed heads that operate similarly but advance line when you tap the head.
For automatic-feed models or newer DeWalt designs, consult your specific product manual, as the spool mechanism and line installation may differ. You can download manuals from DeWalt’s support website using your model number.
Always verify your model’s specifications before purchasing trimmer line, as gauge and length vary. A .065-inch line will not work properly if your model requires .080-inch line, and using incorrect line length can affect both performance and safety.
Buyer FAQs: How To String A Dewalt Weed Eater Solved
What gauge trimmer line does my DeWalt weed eater use?
The correct gauge depends on your specific model and is listed in your product manual or on DeWalt’s website. Most DeWalt models use either .065-inch or .080-inch line. Using the wrong gauge can cause feeding problems or poor cutting performance. Check your model number and verify before purchasing line.
Can I use any brand of trimmer line on my DeWalt weed eater?
Yes, any trimmer line matching your model’s gauge and line-type specification will work. You don’t need to use only DeWalt-branded line. However, ensure the line is the correct gauge and material, nylon line is standard, though some models accept specialty line types. Verify compatibility before purchasing.
How often should I replace trimmer line?
Line life depends on usage frequency and cutting conditions. If you use your trimmer weekly on a typical residential lawn, expect to restring every 2 to 4 weeks. Heavy use or frequent contact with rocks and hard surfaces depletes line faster. Keep spare line on hand for quick replacement.
What if my DeWalt trimmer head still won’t work after restringing?
First, verify the line is wound in the correct direction and wound tightly enough to feed smoothly. Ensure the spool head cap is fully seated and secure. If the problem persists, inspect the eyelets for damage or blockages. If the spool itself is cracked, it may need replacement. Contact DeWalt customer support or consult your manual for parts replacement options.
