Understanding Your Homelite Gas Weed Eater
Most Homelite gas weed eaters, including the UT335, UT400, and XT Series, use a dual-line bump-feed spool system. This system holds two strands of trimmer line that are fed out automatically when you tap the bottom of the spool on the ground while the tool is running. Unlike electric models, Homelite gas units have no cord or battery to manage, so restringing focuses entirely on the cutting head assembly. Most models also include a removable blade guard that protects you from debris and guides the line for a consistent cut. If you’re unsure about your model’s specific design, consult your owner’s manual for diagrams of the spool and cutting head components.
When to Restring Your Homelite Gas Weed Eater
Waiting too long to replace worn line leads to poor cutting performance, spool damage, and safety hazards. Restring your Homelite gas weed eater as soon as you notice any of these signs:
- Line is worn down to less than 3 inches, even after bump-feeding
- Line breaks frequently while cutting light grass
- The weed eater tears grass instead of making clean cuts
- The spool is tangled and won’t feed line smoothly
- Broken plastic line is scattered across your lawn after use
As a general rule, restring every 10 to 15 hours of regular use, or every 2 to 3 months for occasional residential use. If you frequently cut thick weeds or work on gravel, restring more often, as abrasive surfaces wear down line faster.
Tools and Materials You’ll Need
Gather these items before you start to avoid interruptions and complete the restringing process in 5 to 10 minutes:
- Replacement trimmer line matching your model’s recommended diameter (usually 0.080 or 0.095 inch; check your owner’s manual or the side of your existing spool)
- Flathead screwdriver (for stuck spool retention knobs)
- Needle-nose pliers
- Work gloves (to protect your hands from sharp line edges)
- Clean rags
- Small brush (old toothbrush works) for cleaning debris
- Utility knife or heavy scissors to cut line
Using the correct line diameter is critical: line that is too thin breaks frequently, while line that is too thick overloads the engine and reduces cutting power.
Safety Precautions Before Starting
Gas-powered weed eaters have hot engine parts and sharp cutting components, so follow these safety steps every time you restring your tool:
Pre-Work Safety Checks
First, turn off the engine and let it cool completely if it was recently used – gas engines can reach over 200°F, and touching hot parts can cause serious burns. Next, disconnect the spark plug boot from the spark plug to eliminate any risk of accidental startup. Finally, wear work gloves to protect your hands from sharp trimmer line edges that can cause deep cuts.
Workspace Preparation
Work in a flat, well-lit area, preferably outdoors. Lay down a tarp or cardboard under the cutting head to catch debris and old line for easy cleanup. Clear clutter from your workspace to avoid tripping, and work in a well-ventilated area to avoid inhaling residual gas fumes. (See Also:How To Clean Carburetor On Weed Eater)
Step-by-Step Guide to Restringing a Homelite Gas Weed Eater
These steps apply to most Homelite gas models, including the UT335, UT400, and XT Series. Always refer to your owner’s manual for model-specific details.
Step 1: Power Down and Prep the Weed Eater
Place the weed eater on a flat surface with the cutting head facing up. Wipe down the cutting head with a clean rag to remove grass clippings and debris that could fall into the spool housing. Confirm the engine is completely cool if it was recently used, then disconnect the spark plug boot from the spark plug to prevent accidental startup.
Step 2: Remove the Old Spool and Line
Locate the spool retention knob on the bottom of the cutting head, turn it counterclockwise to loosen, and remove it. Pull the old spool straight out of the housing, then pull out any remaining old line. Use a small brush or rag to clean out grass and debris from the spool cavity to prevent tangles. Inspect the spool for cracks or damage, and replace it if needed.
Step 3: Prepare the New Trimmer Line
Cut 10 to 12 feet of new trimmer line (the standard length for most Homelite dual-line spools) to the correct length for your model. File the cut ends slightly if they are ragged to prevent snagging. Use line that matches the recommended diameter for your model (usually 0.080 or 0.095 inch).
Step 4: Wind the New Line Correctly
This is the most critical step to avoid tangles and feed issues. Check your spool for arrows indicating the correct winding direction for each side. For dual-line spools, wind each half of the line in opposite directions, leaving 6 to 8 inches of line sticking out of each eyelet. Make sure the lines do not cross over each other while winding, as this causes tangles. Wind the line snugly, but do not stretch it tight.
Step 5: Reinstall the Spool and Test
Align the spool tabs with the slots in the cutting head housing, push the spool in until it clicks, then tighten the retention knob clockwise until snug (do not overtighten). Reconnect the spark plug, start the engine, and tap the spool on the ground to bump-feed the line. Adjust the line length to 6 to 8 inches from the blade guard, then test cutting a small patch of grass to confirm proper performance. If the line is not feeding smoothly, turn off the engine, disconnect the spark plug, and remove the spool to check for winding errors or debris.
Choosing the Right Trimmer Line for Your Homelite Gas Weed Eater
Using the correct trimmer line reduces breakage, improves cutting performance, and extends the life of your weed eater. Keep these two factors in mind when selecting replacement line:
Line Diameter Considerations
Most Homelite gas models use 0.080 or 0.095 inch diameter line. Thinner line breaks frequently, while thicker line overloads the engine. Check your owner’s manual, the side of your existing spool, or the Homelite website for the exact recommended diameter for your model. For most residential use, 0.080 inch line is sufficient; use 0.095 inch for thicker weeds and brush. (See Also:How Much Line To Put On Weed Eater)
Line Shape Options
Round line is the most durable and versatile, ideal for light grass, edging, and general use. Square line cuts thicker weeds cleanly and edges well, but breaks more easily on hard surfaces. Star/serrated line is for heavy brush and woody vegetation, but wears down quickly. Twisted/composite line is a premium, durable option for frequent users. For most Homelite gas models, 0.080 inch round or square line is the best all-around choice.
| Line Shape | Best Use Case | Durability | Cutting Performance | Recommended For Homelite Gas Models? |
|---|---|---|---|---|
| Round | Light grass, weeds, edging | High (resists breaking on rocks/gravel) | Good for thin vegetation, less effective on thick weeds | Yes, ideal for residential lawns |
| Square | Thick weeds, overgrown grass, light brush | Medium (can break on very hard surfaces) | Excellent clean cut, edges well | Yes, best for most general use |
| Star/Serrated | Heavy brush, woody vegetation, dense overgrowth | Low (wears down faster on hard surfaces) | Aggressive cutting, handles thick material well | Only for heavy-duty Homelite gas models (e.g., UT400 series) |
| Twisted/Composite | All-purpose use, heavy debris | Very High (resists breaking and wear) | Consistent cutting, less vibration | Yes, premium option for frequent use |
Tips for Longer Line Life and Better Performance
Follow these best practices to reduce how often you need to restring your Homelite gas weed eater and keep it performing at its best:
- Store unused trimmer line in a cool, dry place out of direct sunlight to prevent it from becoming brittle.
- Avoid running the weed eater over gravel, rocks, or concrete unless necessary, as these surfaces wear down line quickly.
- Use a blade attachment for thick brush or woody vegetation thicker than your line diameter, rather than overloading the trimmer.
- Wind line snugly but not tight on the spool to prevent binding and breakage.
- Clean the spool cavity every 2 to 3 restrings to remove built-up grass and debris that cause tangles.
- Inspect the spool for sharp edges or damage each time you restring, and replace it if needed to avoid snagging.
Common Mistakes to Avoid
Avoid these common errors to make restringing faster and prevent performance issues:
- Winding line in the same direction on both sides: This causes immediate tangles. Always follow the winding direction arrows on your spool, and wind each side in opposite directions.
- Overtightening the spool knob: This can crack the plastic cutting head housing. Tighten until snug, then stop.
- Using the wrong line diameter: Too-thin line breaks frequently; too-thick line strains the engine. Always confirm the correct diameter for your model before purchasing line.
- Skipping the spark plug disconnect: This is a major safety hazard that can cause accidental startup and serious injury. Always disconnect the spark plug before working on the cutting head.
- Leaving excess line sticking out of the spool: More than 8 inches of line can tangle in the housing or wrap around the engine shaft. Trim excess line after installation if needed.
- Skipping the spool cleaning step: Leftover grass and debris cause tangles and feed issues. Take 30 seconds to clean the cavity before installing a new spool.
Frequently Asked Questions
How often should I restring my Homelite gas weed eater?
Most Homelite gas models need restringing every 10 to 15 hours of regular use, or every 2 to 3 months for occasional use. Restring immediately if you notice the line is shorter than 3 inches, breaks frequently, or the weed eater tears grass instead of cutting cleanly. Regular restringing prevents spool damage and ensures consistent performance.
Can I use aftermarket trimmer line in my Homelite gas weed eater?
Yes, as long as the aftermarket line matches the recommended diameter for your model (usually 0.080 or 0.095 inch). Avoid cheap low-quality line, as it breaks easily and can damage the spool feed mechanism. Always confirm compatibility with your owner’s manual before purchasing.
Why is my new line breaking immediately after restringing?
This is almost always caused by one of three issues: the line is wound in the wrong direction, the line is too thick for your model, or there is debris or a sharp edge in the spool cavity snagging the line. Double-check the winding direction arrows on your spool, confirm the line diameter is correct, and clean the spool cavity thoroughly before installing the new spool.

Do I need to adjust the line length after restringing?
Yes, after starting the engine, adjust the line to extend 6 to 8 inches from the blade guard. Tap the bottom of the spool on a hard surface to bump-feed more line out, or use the adjustment knob (if your model has one) to release or retract line. Never let the line extend more than 8 inches, as this strains the engine and reduces cutting efficiency.
