Understanding Weed Eater String Types
Monofilament vs. Twisted vs. Serrated
Most trimmers accept three broad categories of cutting line. Monofilament line is a single‑strand nylon filament; it is inexpensive, flexible, and works well for light grass and weeds. Twisted line consists of two or more strands twisted together, offering greater tensile strength and a quieter cut, making it a favorite for medium‑duty jobs. Serrated or “star‑shaped” line features sharp edges that slice through thick brush and woody stems more aggressively, but it wears faster on hard surfaces like concrete. Knowing which type your spool is designed for helps you choose the correct replacement and prevents the line from binding during feed.
Diameter also matters. Common sizes range from 0.065 in (1.65 mm) for light residential models to 0.105 in (2.67 mm) for commercial‑grade heads. Using a line that is too thick can jam the feed mechanism, while a line that is too thin may break prematurely. Always consult the owner’s manual for the recommended diameter and shape before purchasing.
Why String Gets Stuck
Common Causes
Several factors cause line to become lodged in the spool or feed eyelet. Over‑winding the spool creates excessive tension, so the line cannot release when the bump feed engages. Dirt, grass clippings, and dried sap accumulate inside the head, increasing friction and preventing smooth payout. A worn or deformed eyelet can pinch the line, especially if the trimmer has been used with an incorrect diameter. Finally, temperature extremes make nylon brittle in cold weather or overly soft in heat, both of which affect feed reliability. Recognizing these causes lets you address the root problem rather than repeatedly pulling on a stuck line.
Tools and Safety Gear Needed
Before starting, gather the following items: a pair of heavy‑duty work gloves to protect your hands from sharp line ends, safety glasses to shield eyes from debris, a small flat‑head screwdriver or the manufacturer’s supplied spool release tool, a clean rag, and a container for the old line. If your model uses a bolt‑on spool, a socket wrench (usually 10 mm or 13 mm) may be required. Ensure the trimmer is completely powered down—remove the battery pack on cordless units or unplug the cord on electric models. For gas‑powered trimmers, disconnect the spark plug wire to eliminate any chance of accidental start.
Step‑by‑Step Manual Feed Removal
Step 1: Power Off and Disconnect
Confirm the engine or motor cannot start. On battery units, press the release latch and slide the pack out. On corded units, pull the plug from the outlet. On gas units, pull the spark plug boot off the plug and secure it away from the electrode.
Step 2: Access the Spool
Locate the spool retainer. Many modern heads have a push‑button or twist‑lock cap; press or turn it counter‑clockwise until the cap releases. On bolt‑on heads, use the appropriate socket to remove the retaining bolt. Set the cap and any springs aside in a clean area.
Step 3: Release the Tension
Gently pull the free end of the line to see if it moves. If it resists, rotate the spool slightly by hand to relieve any built‑up tension. Do not force it; excessive pulling can snap the line inside the eyelet.
Step 4: Pull Out the Old String
Grasp the line near the eyelet with gloved fingers and pull steadily. If the line is knotted or fused, use the flat‑head screwdriver to carefully pry the knot free. Continue pulling until the entire length is removed from the spool and the feed eyelet.
Step 5: Inspect and Clean
Examine the spool for cracks, the eyelet for deformation, and the interior for debris. Wipe the spool cavity and eyelet with a rag. If the eyelet shows wear, consider replacing the head assembly to avoid future feeding problems.
Replacing with New String
Choosing the Right Diameter
Match the new line diameter to the specification in your manual. Using the correct gauge ensures proper feed tension and cutting efficiency. If you frequently cut thick brush, a slightly heavier line within the allowed range can improve durability.
Winding the Spool Correctly
Cut a length of line roughly twice the spool’s capacity (typically 10–15 ft). Insert one end into the anchor hole on the spool, then wind the line in the direction indicated by the arrow on the spool—usually clockwise when viewed from the top. Keep the turns tight and even, avoiding overlaps. Leave about 6 in of line protruding from each eyelet, then snap the cap back on, re‑engage any springs, and secure the retainer.
Comparison Table: String Types vs. Applications
| String Type | Diameter Range | Best For | Durability |
|---|---|---|---|
| Monofilament | 0.065–0.080 in | Light grass, edging | Low |
| Twisted | 0.080–0.095 in | Medium weeds, mixed terrain | Medium |
| Serrated / Star | 0.095–0.105 in | Thick brush, woody stems | Medium‑High |
| Commercial‑Grade Polymer | 0.105 in+ | Heavy‑duty commercial use | High |
Tips for Smooth String Feeding
- Always wind the line in the direction marked on the spool; reverse winding causes immediate jams.
- Trim the line ends at a 45° angle before inserting them into the eyelets to reduce snagging.
- Periodically spray a light silicone lubricant on the eyelet (avoid petroleum‑based products) to lower friction.
- Store the trimmer in a dry, temperature‑controlled area to prevent nylon degradation.
- Replace the spool spring annually if the bump feed feels weak or inconsistent.
Common Mistakes and How to Avoid Them
- Over‑filling the spool: Leaves no room for the line to expand during operation, leading to binding. Fill only to the indicated line‑level mark.
- Using the wrong diameter: Causes either excessive tension or premature breakage. Verify the spec before buying.
- Forcing a stuck line: Can snap the line inside the head, making removal harder. Apply gentle, steady pressure and rotate the spool to relieve tension.
- Neglecting eyelet wear: A worn eyelet pinches line and creates uneven feed. Inspect and replace the head if the eyelet shows grooves.
- Skipping safety steps: Working on a powered trimmer risks serious injury. Always disconnect power sources before servicing.
Troubleshooting Persistent Feeding Issues
If the line still refuses to feed after a clean spool and fresh line, check the bump knob mechanism. Remove the knob, clean any grass buildup, and ensure the internal spring returns the knob sharply. On automatic feed heads, verify that the feed pawl engages the spool teeth; a worn pawl may need replacement. For gas models, a clogged air filter can cause the engine to run rough, reducing centrifugal force that assists line feed. Clean or replace the filter as part of routine maintenance. If problems persist, consult the manufacturer’s service manual or contact an authorized repair center.
Maintenance Schedule for Longevity
Adhering to a simple schedule keeps the feed system reliable. After each use, brush off grass clippings from the head and wipe the eyelet. Weekly, inspect the spool for cracks and the line for fraying. Monthly, lubricate the eyelet with a silicone spray and test the bump feed action. Annually, replace the spool spring, examine the drive shaft for wear, and, if applicable, change the gear oil in the gearbox. Keeping a log of these tasks helps you spot trends before they become costly repairs.
Frequently Asked Questions
How often should I replace the cutting line?
Replace the line whenever it becomes shorter than 3 in, shows visible fraying, or fails to feed smoothly. Heavy use may require replacement every few hours, while light residential use can go several sessions.
Can I use any brand of line in my trimmer?
Most brands are interchangeable as long as the diameter and shape match the manufacturer’s specifications. Using an incompatible line can void the warranty and cause feeding problems.
Why does my line keep breaking at the eyelet?
Breakage at the eyelet usually indicates a sharp edge or burr on the eyelet, incorrect line diameter, or excessive tension from over‑winding. Inspect and smooth the eyelet, verify the line size, and rewind with proper tension.
Is it necessary to lubricate the spool?
A light silicone lubricant on the eyelet reduces friction and extends line life. Avoid oil‑based lubricants, which attract dirt and can degrade nylon.
What should I do if the bump knob won’t release line?
Remove the knob, clean out debris, and check the internal spring for fatigue. If the spring is weak, replace it. Ensure the spool rotates freely when the knob is pressed.
Can I convert a bump‑feed head to an automatic‑feed head?
Some manufacturers offer conversion kits, but compatibility varies. Check the model number and consult the manufacturer before attempting a conversion, as improper installation can damage the drive shaft.
