Introduction
Learning how to respool a Craftsman weed eater is a routine maintenance task that restores clean cutting without requiring special mechanical skills. A worn or empty spool can leave uneven grass, expose the trimmer head, and make the machine work harder than necessary.
Most removable-spool Craftsman trimmers can be rewound in 15 to 30 minutes. The important variables are the correct line diameter, the amount of line the head accepts, and the winding direction marked on that particular spool.
Craftsman has produced fixed-spool, quick-load, single-line, dual-line, bump-feed, and automatic-feed heads, so one universal procedure does not fit every model. This tutorial covers the standard process, explains the main variations, and shows how to correct the problems that usually occur after respooling.

Know Your Craftsman Spool System
Before cutting new line, identify the trimmer model and cutting-head design. The model number is commonly printed on a decal on the shaft, motor housing, or drive housing. That number lets you verify the approved line size and any model-specific loading instructions.
Inspect the spool, cover, guard, and head for markings. Many Craftsman heads list a diameter such as 0.065, 0.080, or 0.095 inch. They may also show arrows for winding, maximum line lengths, or the number of lines the spool accepts.
- Fixed-spool head: The cover opens so the spool can be removed and wound by hand.
- Quick-load head: Pre-cut line is inserted into loading holes and captured while the knob or spool is rotated.
- Bump-feed head: The operator taps the center of the running head against the ground to release more line.
- Automatic-feed head: Line advances as the head spins, although it may still require an initial pull or occasional assistance.
Single-line and dual-line describe how many cutting strands exit the head. Bump and automatic describe how line advances. A dual-line head may use bump feed, while a single-line head may use an automatic mechanism, so these terms should not be treated as interchangeable.
Tools and Replacement Line
Use the line diameter and type recommended for the model. Round nylon line is common, but some heads accept twisted, square, or other profiles. A larger diameter does not make the trimmer more effective if the eyelets and internal spool are designed for a smaller line.
- Fresh trimmer line of the correct diameter
- Heavy-duty scissors, line cutters, or utility snips
- A ruler or measuring tape
- Work gloves and eye protection
- A clean cloth and small brush
- A container for springs, screws, and other small parts
- Only the hand tools specified by the owner’s manual
Measure every piece before winding. Many dual-line heads use equal lengths on both sides, but the required amount can range from less than 10 feet to more than 20 feet per eyelet. Follow the head marking rather than filling the spool until no space remains.
Inspect the line for brittleness, flattening, cracks, or discoloration. Old line stored in heat or direct sunlight can break inside the head. When the package and trimmer manual disagree, the Craftsman manual for the exact model is the safer reference.
Remove the Head and Spool
Place the trimmer on a stable, well-lit surface with the cutting head easy to reach. Keep children and pets away, and work only after the motor or engine has cooled.
- Disable the power source. Unplug a corded electric trimmer, remove the battery from a cordless model, and disconnect the spark plug boot from a gas engine.
- Wear protection. Gloves reduce contact with sharp line ends and debris, while eye protection keeps dirt out of your eyes.
- Remove the cover or head. Some caps twist off by following the molded arrows. Other designs require the entire head to be held while a retaining nut is turned. Use the direction shown on the head or in the manual; do not assume every thread loosens the same way.
- Control small components. Springs and retaining parts can pop loose. Cover the head with one hand and place every piece in a container in the order it was removed.
- Stop if force is required. A stuck head may have a locking button, reverse thread, or damaged retaining nut. Forcing it can crack the housing or damage the drive shaft.
Once open, remove the spool and examine the cavity. Clear compacted grass, plastic fragments, and old line. Check the cover tabs, eyelets, spring, retaining nut, and spool for cracks or wear. Replace a damaged head or spool instead of trying to hold a cracked component together during operation.
How to Respool Craftsman Weed Eater? Step-by-Step Instructions
The following procedure applies to a typical Craftsman head with a removable spool and cover. Read the arrows on your spool before beginning, because winding direction is determined by the head design rather than the Craftsman brand alone.
- Confirm the line capacity. Locate the line diameter and maximum length printed on the spool or head. If the marking gives a total capacity for a dual-line spool, divide that amount into two equal pieces unless the manual states otherwise.
- Cut clean, equal lengths. Use sharp cutters so the ends are not crushed. Equal pieces help balance the spool and make it easier to seat both leads in their retaining notches.
- Find the anchor point. Look for a small hole, slot, or molded notch in the center of the spool. Bend about one-quarter inch from the end of one line if needed to hook it securely.
- Wind the first line. Hold the anchored end and turn the spool in the direction of the arrow. Keep the line between the spool’s side flanges, snug, and parallel. Do not cross one wrap over another or pile line against only one edge.
- Leave the specified lead. Stop before the final few inches and place the loose end in the temporary retaining notch. Leave about six inches outside the spool unless the head specifies a different length.
- Wind the second line. Anchor and wind the other piece in its own chamber or section. Some spools show two arrows that direct the lines in opposite directions. Follow those markings even when they differ from the first side.
- Check the finished spool. The wraps should fill the chamber evenly without rising above the flanges. If the spool bulges, the cover will not seat correctly and the line may jam.
- Reinstall internal parts. Return the spool to the head in the same orientation. Replace the spring or spring cup only if your model uses one, and make sure it sits flat rather than leaning against the spool.
- Route both line ends. Pull each lead through its matching exit eyelet. Keep the lines separate, straight, and free of twists before replacing the cover.
- Secure the cover and release the leads. Align the cover tabs, then turn or press it until it locks. Pull both strands firmly so they slip out of their temporary notches and extend evenly from the head.
Some Craftsman quick-load heads do not require the cover to be removed. On those models, insert each pre-cut line into the loading eyelet or side hole until an internal catch grips it, then rotate the knob in the marked direction. Repeat for the second line and leave the recommended amount exposed. Stop if the knob binds instead of forcing it.
If the spool has no arrow, do not guess based on another trimmer. Consult the owner’s manual or use a photograph taken before disassembly. When neither is available, examine how the original line was routed and contact Craftsman support for the model-specific direction.
Reinstall and Test the Respooled Head
- Verify that the spring, spool, and cover are fully seated.
- Align all locking tabs before turning the cover.
- Thread both lines smoothly through the correct eyelets.
- Pull the lines to release them from the spool notches.
- Reattach a threaded head according to the arrows on its housing.
- Check that both strands move freely by hand without rubbing the cover.
Restore power only after the head is fully assembled. Stand clear of people, pets, stones, and hard objects. Start the trimmer at its normal operating speed and use the prescribed bump or automatic-feed action. Tap a bump head lightly on bare ground; repeated hard pounding can damage the mechanism.
Most guards include a small line-cutting blade that trims newly released line to the proper length. Confirm that this cutter is present and secure. If the line remains excessively long, stop the machine and inspect the cutter rather than cutting line near a moving head by hand.
Single-Line, Dual-Line, and Feed Systems
Choosing the correct replacement spool is as important as winding it correctly. The table below separates loading method from line-advance method, which helps prevent confusion when comparing Craftsman trimmer heads.
| System | How It Is Loaded | How Line Advances | Main Caution |
|---|---|---|---|
| Fixed spool with bump feed | Remove the cover and wind line onto the spool | Lightly tap the center while the head is running | Do not overfill or leave the leads trapped in the notches |
| Quick-load bump head | Insert pre-cut line into loading holes and rotate the knob | Tap the running head on the ground | Use the marked eyelets and stop if the knob binds |
| Automatic-feed head | Usually uses a removable, hand-wound spool | Advances while the head rotates | Line may still need an initial pull and clean eyelets |
| Single-line head | Uses one anchored and wound strand | May be bump or automatic feed | Do not add a second line unless the head is designed for it |
Dual-line heads provide two cutting strands and are common for general trimming. Single-line heads are often intended for lighter work. Do not convert a head by drilling extra eyelets or installing an unapproved spool, because imbalance and line failure can create a safety hazard.
Troubleshooting and Common Mistakes
- Line will not advance: Check whether either lead is still caught in a retaining notch. Also inspect the eyelets for debris and confirm that the spring is seated correctly.
- Only one side feeds: The lines may be crossed, one chamber may be overfilled, or one lead may be bent sharply inside the head. Remove the cover and rewind both sides evenly.
- Line feeds and then jams: This usually indicates loose wraps, overlapping coils, too much line, or a lead that slipped beneath another wrap. Empty the spool and start again with shorter pieces if necessary.
- Line breaks or shreds: Use fresh line of the specified diameter. Check for rough or cracked eyelets, a damaged cutter, and line that has become brittle from age or heat.
- The head rattles: Turn the trimmer off and reopen it. A tilted spring, loose retaining nut, cracked cover, or incorrectly seated spool can cause noise and poor feeding.
- The cover will not lock: Do not force it. Confirm that the line sits below the spool flanges, the spring is flat, and every tab is aligned with its slot.
- Too much line comes out: The bump mechanism may be sticking, the spring may be weak, or the line may have been loaded loosely. Clean the head and inspect its internal parts before using it again.
- The trimmer performs poorly after respooling: Excessively long or heavy line can overload the head. Return to the approved diameter and length, and make sure both sides remain balanced.
If correct line, even winding, clean eyelets, and a properly seated spring still do not solve the problem, the feed pawls or spring may be worn. Replace the damaged components or the complete head rather than lubricating the spool. Oil and grease attract grit and can worsen feeding.
Tips and Best Practices
- Respools before the line is completely gone. Leaving two or three inches reduces the chance of losing the old lead inside the head.
- Keep a second spool already wound with the correct line. It makes the next replacement faster and provides a useful comparison if winding direction is unclear.
- Store spare line in a cool, dry place away from sunlight. Fresh line bends more easily and is less likely to snap during trimming.
- Wind with steady tension, but do not stretch the line. Stretching can make it retract and feed unevenly later.
- Clean grass and debris from the head whenever the cover is open. A clear exit path reduces friction and heat.
- Record the approved line size and measured lengths on the spare-spool container. This prevents guessing during the next maintenance session.
- Replace cracked spools, worn springs, stripped covers, and damaged eyelets as a set when needed. Mixing badly worn parts with new parts often causes recurring jams.
The best results come from matching the head, spool, and line exactly. A neat spool with the proper amount of line generally feeds more reliably than a completely packed spool.
Frequently Asked Questions
How Much Trimmer Line Should I Put on a Craftsman Spool?
Use the length printed on the spool or cutting head. Many Craftsman dual-line heads accept roughly 10 to 25 feet per eyelet, but smaller heads may require less. If a marking states total capacity, divide it equally between the two sides and leave the recommended exposed lead.
Which Direction Do I Wind a Craftsman Weed Eater Spool?
Follow the arrow molded into the spool. If no arrow is visible, check the owner’s manual, the original line routing, or a photograph taken before removal. Craftsman heads do not all wind in the same direction, so another model should not be used as the reference.
Why Does My Craftsman Trimmer Line Not Feed After Respooling?
The most common causes are leads left in the retaining notches, crossed or overlapping wraps, an overfilled spool, blocked eyelets, the wrong line diameter, or a spring installed at an angle. Stop the trimmer, reopen the head, and correct the winding before testing it again.
Conclusion
Knowing how to respool a Craftsman weed eater comes down to using the correct line, following the spool’s winding arrow, keeping the coils even, and leaving enough lead to pass through the eyelets. Safe power isolation, a clean head, and a properly seated spring are just as important as the winding itself.
After reassembly, pull both strands free, confirm that they move smoothly, and test the feed in a clear area. If feeding remains unreliable, inspect for incorrect line size, internal damage, or worn feed parts. When model instructions and general advice differ, the manual for the exact Craftsman trimmer should always take priority.
