Understanding the Spool
The spool (often called the trimmer head) houses the cutting line and feeds it outward as the line wears down. Homelite models typically use a bump‑feed or automatic‑feed head. In a bump‑feed head you tap the head on the ground to advance line; in an automatic‑feed head the line advances on its own. Both designs rely on a correctly wound spool to function. The spool consists of a central hub, two side flanges, and a spring‑loaded eyelet that guides the line. When the line is wound unevenly or too loosely, the feed mechanism can jam, causing the trimmer to stall or the line to break prematurely.
Before you begin, identify the exact model number of your Homelite weed eater. The model number is usually printed on a label near the motor housing or on the side of the shaft. Knowing the model ensures you purchase the correct diameter line (commonly 0.080 in, 0.095 in, or 0.105 in) and the proper replacement spool if the original is damaged. A mismatched line diameter can cause excessive vibration, reduced cutting power, or even damage to the drive shaft.
Tools and Materials Needed
Gathering the right tools before you start makes the job smoother and safer. The following list covers everything you will need for a typical rewind:
- Replacement trimmer line (matching the diameter specified for your model)
- Scissors or a sharp utility knife for cutting the line
- Work gloves to protect your hands from sharp edges
- Safety glasses to shield your eyes from debris
- Flat‑head screwdriver (if your spool is secured with a screw)
- Clean rag or shop towel for wiping the spool housing
- Small brush (an old toothbrush works well) for removing grass buildup
Optional but helpful items include a line‑winding tool (a simple plastic jig that holds the spool while you wind) and a torque wrench if the manufacturer specifies a tightening torque for the spool retaining bolt. Having these on hand reduces the chance of stripping threads or winding the line unevenly.
Safety Precautions
Working on a power tool always carries risk, so observe these precautions before you touch the trimmer:
- Disconnect the spark plug wire (gas models) or remove the battery (cordless models) to prevent accidental starts.
- Allow the engine to cool completely if the trimmer has been running recently.
- Wear safety glasses and gloves at all times.
- Work on a stable, flat surface with good lighting.
- Keep children and pets away from the work area.
Following these steps eliminates the possibility of the motor engaging while your hands are near the spinning head, which is the most common cause of injury during line replacement.
Step‑by‑Step Rewind Guide
The following ordered list details the complete rewind procedure. Perform each step in sequence; skipping a step can result in a poorly wound spool that feeds incorrectly.
- Remove the spool. Locate the retaining knob or screw on the trimmer head. Turn it counter‑clockwise (or unscrew) until the spool releases. Pull the spool straight off the shaft.
- Inspect and clean the spool housing. Use the brush and rag to remove grass clippings, dirt, and old line fragments from the hub, flanges, and eyelet. A clean housing ensures smooth line feed.
- Measure and cut the new line. Consult the owner’s manual for the recommended length; a typical range is 10–15 feet per side. Cut two equal lengths of line using scissors or a utility knife.
- Load the line onto the spool. Insert one end of the first line into the anchor hole on the upper flange. 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. When the first line is fully wound, secure the end in the opposite anchor hole. Repeat for the second line on the lower flange, winding in the opposite direction if the spool is dual‑directional.
- Reinstall the spool. Align the spool’s central hub with the drive shaft and slide it on until it seats fully. Replace the retaining knob or screw and tighten securely, but do not overtighten.
- Test the trimmer. Reconnect the spark plug wire or battery. Start the engine and let it idle. Tap the head gently on the ground (bump‑feed) or engage the automatic feed to verify that line advances smoothly. Listen for unusual vibration or noise.
If the line does not feed, double‑check that the line is wound in the correct direction and that the anchor holes are properly seated. A mis‑wound spool is the most frequent cause of feed failure.
Line Types and Compatibility
Choosing the right trimmer line influences cutting performance, line life, and engine load. The table below compares the most common line profiles used with Homelite weed eaters.
| Line Profile | Diameter (in) | Best For | Pros | Cons |
|---|---|---|---|---|
| Round | 0.080 – 0.105 | General grass and light weeds | Low cost, low drag, easy to wind | Wears faster on thick brush |
| Twisted (Helical) | 0.080 – 0.095 | Medium‑duty weeds and light brush | Reduced vibration, quieter operation | Slightly higher price |
| Square / Star | 0.095 – 0.105 | Heavy brush, thick weeds, edging | Aggressive cutting, longer life | Higher drag, more engine load |
| Serrated / Saw‑tooth | 0.095 – 0.105 | Very tough vegetation, small saplings | Maximum cutting efficiency | Can damage delicate plants, highest drag |
Match the line diameter to the specification in your owner’s manual. Using a larger diameter than recommended can overheat the motor, while a smaller diameter may break frequently.
Tips for Longer Line Life
Extending the usable life of your trimmer line reduces the frequency of rewinds and saves money. Apply these best practices:
- Store the trimmer in a dry, shaded area; UV exposure makes line brittle.
- Keep the spool clean; debris trapped between the line and flanges accelerates wear.
- Use the correct line diameter; oversized line creates excess friction.
- Adjust the feed mechanism (if adjustable) so that only the necessary amount of line extends.
- Avoid forcing the trimmer into dense, woody material; use a brush cutter attachment for that work.
- Periodically lubricate the spool’s eyelet with a light silicone spray to reduce friction.
Implementing even a few of these habits can double the number of cuts you get per spool.
Common Mistakes and How to Avoid Them
Even experienced users make errors that lead to poor feed or damaged equipment. The list below highlights the most frequent pitfalls and the corrective actions.
- Winding line in the wrong direction. Always follow the arrow on the spool; reverse winding causes the line to bind.
- Over‑filling the spool. Excess line prevents the eyelet from releasing line cleanly. Leave a small gap (about 1/8 inch) between the wound line and the flange edge.
- Using mismatched line diameter. Verify the spec before purchase; a 0.105 in line on a 0.080 in head will jam.
- Neglecting to clean the housing. Grass buildup creates uneven tension and can snap the line.
- Overtightening the retaining knob. This can strip the threads or crack the spool flange. Tighten until snug, then stop.
Checking each of these points before you start the engine eliminates the majority of post‑rewind problems.
Troubleshooting After Rewind
If the trimmer still behaves oddly after a fresh rewind, run through this quick diagnostic checklist:
- Line does not advance. Verify winding direction, ensure the line is not tangled, and confirm the bump‑feed knob moves freely.
- Excessive vibration. Check for uneven line length on the two flanges; re‑wind if necessary.
- Line breaks immediately. Inspect for sharp edges on the spool flanges or eyelet; file down any burrs.
- Engine stalls under load. The line diameter may be too large; switch to the recommended size.
- Unusual noise from the head. The spool may be loose; re‑tighten the retaining knob to the proper torque.
Most issues resolve with a careful re‑inspection of the spool and line. If problems persist, consult the service manual or contact a certified Homelite repair center.
Maintenance After Rewind
After a successful rewind, a few minutes of preventive maintenance keep the trimmer running smoothly for the next season.
- Wipe the entire shaft and motor housing with a damp cloth to remove dust and grass sap.
- Inspect the air filter (gas models) and clean or replace it according to the schedule.
- Check the spark plug for fouling; replace if the electrode is worn.
- Lubricate the drive shaft’s flexible coupling with a light grease if the manual recommends it.
- Store the trimmer with the spool removed if you will not use it for several months; this prevents the line from developing a permanent set.
Regular upkeep reduces the likelihood of unexpected breakdowns and prolongs the overall lifespan of the tool.
Frequently Asked Questions
How often should I rewind my Homelite weed eater?
The frequency depends on usage intensity and line type. For typical residential use with round line, expect to rewind every 2–4 hours of cutting. Heavy‑duty line or commercial use may require more frequent changes.
Can I use any brand of trimmer line?
Yes, as long as the diameter and profile match the specifications for your model. Quality brands often provide more consistent diameter and better abrasion resistance.
Why does the line keep breaking right after I rewind?
Common causes include winding the line too loosely, using a line diameter larger than recommended, or a damaged eyelet with sharp edges. Inspect the spool and re‑wind with proper tension.
My bump‑feed head won’t release line. What should I do?
First, ensure the spool is seated correctly and the retaining knob is tight. Then verify the line is wound in the direction of the arrow. If the problem persists, the internal spring may be worn and the head may need replacement.
Can I adjust the automatic feed on my Homelite trimmer?
Some models have an adjustment screw on the head that controls feed length. Refer to the owner’s manual for the exact procedure; improper adjustment can cause over‑feeding or jamming.
