Understanding Your Weed Eater
Types of Trimmers
String trimmers fall into three broad categories: gas‑powered, corded electric, and battery‑operated. Gas models typically use a bump‑feed or fixed‑line head that requires manual winding, while many electric and battery units feature an automatic feed system that advances line when you tap the head on the ground. Knowing which type you own determines whether you’ll be winding line onto a removable spool or simply threading a pre‑cut length through a fixed eyelet.
Spool Mechanisms
The spool is the cylindrical cartridge that holds the cutting line. Two common designs exist: the single‑line spool where one continuous strand is wound in a single direction, and the dual‑line spool that accepts two separate strands wound in opposite directions for a wider cutting swath. Some manufacturers also offer a pre‑wound cartridge that snaps into place without any winding at all. Identifying your spool style before you start saves time and prevents the frustration of trying to force the wrong line into the wrong slot.
Tools and Materials Needed
You only need a handful of items to reload a trimmer line:
- Replacement trimmer line of the correct diameter (commonly 0.065 in, 0.080 in, or 0.095 in).
- A pair of heavy‑duty scissors or a utility knife for cutting the line.
- Work gloves to protect your hands from sharp edges and hot engine parts.
- Safety glasses or goggles to shield your eyes from debris.
- A clean rag or shop towel for wiping the spool housing.
- Optional: a small flat‑head screwdriver if your model uses a retaining screw on the spool cap.
Check the owner’s manual for the exact line diameter and length recommended for your model. Using the wrong gauge can cause excessive vibration, premature wear, or even damage the motor.
Safety Precautions
Before you touch any part of the cutting head, observe these safety rules:
- Power off completely. For gas units, turn the ignition switch to “Off” and disconnect the spark plug wire. For electric models, unplug the cord or remove the battery pack.
- Allow the engine to cool. A hot muffler or motor can cause severe burns.
- Wear protective gear. Gloves and eye protection are non‑negotiable.
- Secure the trimmer. Place the unit on a stable workbench or the ground with the cutting head facing up so it cannot roll or tip.
- Keep bystanders away. The line can snap and whip outward during installation.
Following these steps eliminates the majority of accidents associated with line replacement.
Step-by-Step Guide: How to Put String Back in Weed Eater
Step 1: Power Off and Disconnect
Confirm that the trimmer is completely de‑energized. On a gas model, pull the spark plug boot off the plug and set it aside. On a corded electric unit, unplug the power cord from the outlet. On a battery model, press the release latch and remove the battery pack. Double‑check that the trigger does not engage the motor. (See Also:How To Feed An Echo Weed Eater 2)
Step 2: Remove the Spool
Locate the spool retaining mechanism. Most residential trimmers use a push‑button or twist‑off cap on the bottom of the cutting head. Press the release button while turning the cap counter‑clockwise, or simply twist the cap if it is a threaded design. Lift the spool straight out of the housing. If a retaining screw is present, loosen it with the screwdriver before removing the cap.
Step 3: Clean the Spool Housing
Use a clean rag to wipe away grass clippings, dirt, and old line fragments from the interior of the head. Debris can interfere with the line feed mechanism and cause jams later. Inspect the eyelets or guide holes for cracks; replace the head if any damage is found.
Step 4: Measure and Cut New Line
Consult the manual for the recommended line length—typically 10 to 25 feet per strand. Pull the required length from the spool of replacement line, then cut it cleanly with scissors or a utility knife. For dual‑line spools, cut two equal lengths. Avoid fraying the ends; a clean cut feeds more smoothly.
Step 5: Load the Line onto the Spool
Identify the winding direction arrows molded into the spool body. Insert one end of the line into the anchor hole or slot, then wind the line tightly and evenly in the direction indicated. Keep tension on the line so it lays flat without overlapping. For dual‑line spools, repeat the process on the opposite side, winding in the opposite direction. Leave about 6 inches of line protruding from each eyelet for the initial feed.
Step 6: Reinstall the Spool
Align the spool with the drive shaft or hub inside the head. Press it down until it seats fully. Replace the cap by turning it clockwise until it clicks or the retaining screw is snug. Ensure the cap is secure; a loose cap will cause the spool to eject during operation.
Step 7: Test the Trimmer
Reconnect the spark plug wire, plug in the cord, or reinsert the battery. Start the trimmer and let it run at idle for a few seconds. Tap the head lightly on the ground (bump‑feed models) or engage the automatic feed trigger. The line should extend evenly from both sides. If the line does not feed, revisit Step 5 to verify winding direction and tension.
Common Spool Types Comparison
| Spool Type | Line Capacity | Feed Method | Typical Use | Ease of Reload |
|---|---|---|---|---|
| Single‑Line Fixed Spool | 10–15 ft | Manual bump feed | Light residential trimming | Moderate – requires winding |
| Dual‑Line Fixed Spool | 20–30 ft total | Manual bump feed | Medium‑duty lawn care | Moderate – two strands to wind |
| Auto‑Feed Cartridge | Pre‑wound 15–25 ft | Automatic (centrifugal) | Electric/battery trimmers | Easy – snap‑in replacement |
| Quick‑Load Spool | 12–20 ft | Semi‑auto (push‑button) | Prosumer gas models | Easy – line feeds through guide |
Tips and Best Practices
- Buy the right diameter. Using a line that is too thick overloads the motor; too thin reduces cutting efficiency.
- Store line in a cool, dry place. UV exposure and moisture make the nylon brittle.
- Wind under tension. A loosely wound spool creates gaps that cause the line to snag.
- Trim the ends at a 45° angle. This helps the line slide through the eyelets without catching.
- Replace the entire spool annually. Even if line remains, the plastic can fatigue and crack.
- Keep a spare spool on hand. Swapping a pre‑wound cartridge is faster than rewinding in the field.
Common Mistakes and How to Avoid Them
- Wrong line diameter. Always verify the spec in the manual; mismatched line leads to vibration and premature wear.
- Winding in the wrong direction. Follow the arrows on the spool; reverse winding prevents the bump‑feed from releasing line.
- Over‑filling the spool. Excess line can bind against the housing and stall the feed mechanism.
- Skipping the cleaning step. Debris left in the head is the leading cause of line jams.
- Not securing the cap fully. A loose cap lets the spool spin freely, ejecting line at high speed.
- Using damaged or frayed line. Frayed ends catch on the eyelets and cause uneven feeding.
Addressing these points before you start eliminates the majority of reload headaches.
Troubleshooting: String Not Feeding
If the line refuses to advance after you have reloaded, run through this checklist: (See Also:How To Attach Weed Eater Line)
- Confirm the spool is seated completely and the cap is locked.
- Verify that the line exits the eyelets without kinks.
- Check that the bump‑feed knob or button moves freely; lubricate with a light silicone spray if it sticks.
- Inspect the drive shaft for wear; a stripped shaft will not spin the spool.
- Ensure the line length matches the manufacturer’s recommendation; too short a length cannot reach the feed mechanism.
- For auto‑feed heads, make sure the centrifugal weights are not stuck by debris.
Most feeding problems resolve after one of these corrections. If the issue persists, the head assembly may need replacement.
Maintenance Tips for Longer Line Life
Extending the interval between reloads saves time and money. Adopt these habits:
- Trim at the recommended engine speed; running wide open unnecessarily wears line faster.
- Avoid cutting hard objects such as rocks, curbs, or thick woody stems.
- Periodically inspect the line for fraying; replace a single worn strand before it snaps.
- Clean the cutting head after each use to prevent grass buildup that accelerates line abrasion.
- Store the trimmer indoors or under a cover to protect the line from UV degradation.
Frequently Asked Questions
What diameter line should I use for my weed eater?
Check the owner’s manual or the label on the spool housing. Most residential trimmers accept 0.065 in, 0.080 in, or 0.095 in line. Using the specified diameter ensures proper feed and motor load.
Can I use any brand of trimmer line?
Yes, as long as the diameter and shape (round, square, twisted) match the manufacturer’s recommendation. Premium lines often last longer and cut cleaner, but generic line works for occasional use.
How often should I replace the trimmer line?
Replace the line when it becomes shorter than about 2 inches on each side, shows excessive fraying, or no longer feeds reliably. For heavy use, this may be every few hours; for light yard work, a spool can last a season.
Why does my line keep breaking at the eyelet?
Sharp edges on a worn eyelet, using line that is too thick, or winding the line too loosely can all cause breakage at the exit point. Inspect the eyelet for burrs and replace the head if necessary. (See Also:How To Start A Stihl Fs91r Weed Eater)
Is it better to buy pre‑wound spools or bulk line?
Pre‑wound spools are faster to install and guarantee correct winding direction, making them ideal for quick swaps. Bulk line is more economical for high‑volume users who don’t mind winding their own spools.
