Understanding Your Dewalt Weed Eater
Dewalt offers several trimmer head designs, each with a slightly different rewinding method. The most common are the bump‑feed head, which releases line when you tap the head on the ground, and the fixed‑line head, where you manually pull line through the eyelets. Some newer models feature a dual‑line spool that holds two strands for faster cutting. Knowing which head you have determines the exact winding direction and the amount of line to load. The owner’s manual lists the recommended line diameter—typically 0.080 in or 0.095 in for residential units and up to 0.105 in for heavy‑duty models. Using the wrong diameter can cause excessive wear on the motor or poor cutting performance.
Head Types and Specifications
Bump‑feed heads usually have a spring‑loaded spool that spins freely; the line is wound in the direction indicated by an arrow on the spool. Fixed‑line heads have a stationary spool with two or four eyelets; you thread the line through each eyelet and then wind it onto the spool. Dual‑line spools require you to load two equal lengths of line side by side, ensuring they feed evenly. Always check the model number on the housing and cross‑reference it with Dewalt’s online parts diagram to confirm the correct head type before you begin.
Tools and Materials Needed
Gathering the right supplies beforehand makes the job smooth and prevents interruptions. You will need a fresh spool of Dewalt‑compatible trimmer line matching the diameter specified for your model. A pair of needle‑nose pliers helps pull the line through tight eyelets, while a small flat‑head screwdriver can release any retaining clips on the head. A clean rag or shop towel is useful for wiping debris from the spool and housing. If your model uses a retaining bolt, a 5 mm or 6 mm hex key (often included with the tool) will be required. Finally, keep a pair of safety glasses and gloves nearby for protection.
Safety Precautions
Before any maintenance, ensure the trimmer is powered off and the battery is removed (or the cord is unplugged for corded units). This eliminates the risk of accidental start‑up while your hands are near the cutting head. Wear safety glasses to shield your eyes from any stray line fragments, and gloves to protect your fingers from sharp edges on the spool or housing. Work on a stable, flat surface with good lighting. Keep children and pets away from the work area. If you notice any cracked housing, damaged springs, or worn eyelets, replace those parts before re‑loading line to avoid future failures.
Step‑by‑Step Guide: How to Rewind Dewalt Weed Eater
- Remove the battery or unplug the unit. Confirm the power source is completely disconnected.
- Detach the trimmer head. Most Dewalt heads unscrew counter‑clockwise; some have a release button that you press while turning.
- Take off the spool from the head housing. Note the winding direction arrow on the spool—this is critical for proper line feed.
- Cut a length of new line. For a single‑line head, measure roughly 10–12 feet; for a dual‑line head, cut two equal pieces of the same length.
- Insert one end of the line into the anchor hole or slot on the spool. Pull it through until a short tail remains.
- Wind the line neatly onto the spool following the arrow direction. Keep tension even and avoid overlapping layers.
- Leave about 6 inches of line free at the end. Thread this tail through the eyelet(s) on the head housing.
- Re‑install the spool into the head, ensuring the line feeds freely through the eyelets. Re‑attach the head to the trimmer shaft, tightening securely.
- Reconnect the battery or plug in the unit. Test the trimmer at low speed to verify smooth line feed.
Following these steps ensures a clean wind and reliable operation. If the line does not feed, double‑check the winding direction and that the line is not tangled inside the spool.
Detailed Walkthrough for Bump Feed vs Fixed Line
Bump‑Feed Head
On a bump‑feed head, the spool rotates freely inside the housing. After removing the head, you will see a small spring that pushes the spool outward when you tap the head. Wind the line in the direction of the arrow—usually clockwise when viewing the spool from the top. Keep the line tight and evenly spaced; a loose wind causes the line to bunch and jam during bump feeding. Once wound, snap the spool back into the housing, making sure the spring seats correctly. The free ends should protrude through the eyelets about 3–4 inches each.
Fixed‑Line Head
Fixed‑line heads have a stationary spool with two or four eyelets. After removing the head, pull the old line out completely. Thread the new line through each eyelet, then bring the ends together at the spool’s anchor point. Wind both strands simultaneously, maintaining equal tension so they feed evenly. Some models require you to lock the line in a small notch on the spool before winding. After winding, tuck the line ends into the retaining slots and re‑assemble the head. Test by gently pulling the line; it should release smoothly without resistance.
Comparison Table: Dewalt String Types
| String Type | Diameter (in) | Best For | Durability | Price Range (per 50 ft) |
|---|---|---|---|---|
| Standard Round | 0.080 | Light residential trimming | Moderate | $8–$12 |
| Twisted (Serpent) | 0.095 | Thicker grass, weeds | High | $12–$18 |
| Square‑Edge | 0.095 | Heavy brush, small saplings | Very High | $15–$22 |
| Commercial‑Grade Dual‑Line | 0.105 | Professional landscaping | Maximum | $20–$30 |
Choosing the right line matches the workload and extends the time between rewinds. Heavier diameters cut faster but increase motor load; always stay within the manufacturer’s recommended range.
Tips for Longer Line Life
- Use the correct diameter for your model; oversized line wears the motor and breaks more often.
- Keep the spool clean—remove grass buildup after each use to prevent friction.
- Avoid cutting hard surfaces like concrete or rocks; they shred line instantly.
- Store the trimmer in a dry place; moisture degrades nylon line over time.
- Wind the line tightly and evenly; loose winds cause uneven feed and premature breakage.
- Replace the line before it becomes too short; a short tail reduces cutting efficiency and stresses the head.
Common Mistakes and How to Avoid Them
- Wrong winding direction: Always follow the arrow on the spool. Reversing it makes the line feed backward or jam.
- Over‑filling the spool: Too much line prevents the spool from spinning freely. Leave the recommended free‑end length.
- Using mismatched line diameters: Mixing 0.080 in and 0.095 in on a dual‑line head causes uneven feed. Use identical strands.
- Neglecting eyelet wear: Worn or cracked eyelets snag line. Inspect and replace them during each rewind.
- Forgetting to disconnect power: Accidental start‑up can cause serious injury. Always remove the battery first.
Maintenance After Rewinding
After you have successfully rewound the line, run the trimmer at low speed for a few seconds to confirm smooth feeding. Check that the line extends evenly from both sides of the head. Wipe any debris from the housing and inspect the spool for cracks. Lubricate the head’s pivot point with a light machine oil if the manufacturer recommends it. Schedule a full inspection of the trimmer—air filter, battery contacts, and cutting guard—at least once per season. Keeping the entire tool clean and well‑lubricated reduces vibration and prolongs motor life, ensuring each rewind lasts longer.
Frequently Asked Questions
How often should I rewind my Dewalt weed eater?
Frequency depends on usage and line type. For typical residential yard work with standard round line, expect to rewind every 30–45 minutes of cutting time. Heavy‑duty twisted or square‑edge line can last 60–90 minutes before needing a refill.
Can I use third‑party trimmer line instead of Dewalt branded line?
Yes, as long as the diameter and shape match the specifications in your owner’s manual. Many aftermarket lines perform equally well, but verify quality reviews to avoid brittle or overly stiff line that could damage the head.
Why does my line keep jamming after I rewind?
Jams usually stem from uneven winding, wrong direction, or debris inside the spool. Re‑wind carefully, ensuring each layer sits flat, and clean the spool cavity before reassembly.
Do I need to replace the spool every time I rewind?
No. The spool is reusable unless it shows cracks, warping, or the anchor hole is stripped. Inspect it each time; replace only when damaged.
Is there a difference between 20V and 60V Dewalt heads when rewinding?
The rewinding procedure is identical; only the recommended line diameter may differ. Always consult the specific model’s manual for the correct size.
