Tools and Materials
Before you begin, gather everything you will need. Having the right supplies on hand prevents interruptions and ensures a smooth workflow. The following list covers the essentials for most Craftsman trimmer models:
- Replacement trimmer line (diameter matched to your model, typically .080 in., .095 in., or .105 in.)
- Protective gloves to shield your hands from sharp edges
- Safety glasses or goggles
- Flat‑head screwdriver or Torx driver (depending on the head fasteners)
- Adjustable wrench or socket set for the spool nut
- Clean rag or shop towel
- Small container for the old line (optional, for recycling)
Check your owner’s manual for the exact line diameter and spool capacity. Using the wrong gauge can cause feeding problems or damage the head. If you are unsure, the model number on the housing will guide you to the correct specification.
Understanding the Spool
The spool is the heart of the line‑feeding system. Craftsman weed eaters typically use either a bump‑feed head or a fixed‑line head. In a bump‑feed head, the line advances each time you tap the head on the ground. A fixed‑line head requires manual line replacement when the line wears out. Both designs share a central hub, a spring‑loaded retainer, and a line guide that directs the line outward. Familiarize yourself with the orientation of the line guide arrows; they indicate the direction the line must be wound. Winding the line opposite to the arrows will cause the line to feed backward and jam.
Most Craftsman spools have a capacity of 10–15 feet of line per side. Over‑filling the spool can lead to binding, while under‑filling reduces cutting time between reloads. The spool may be split into two chambers (dual‑line) or a single chamber (single‑line). Dual‑line heads cut faster because two strands engage the vegetation simultaneously.
Preparing the Weed Eater
Safety first. Disconnect the spark plug wire (or remove the battery on cordless models) to prevent accidental starts. Place the trimmer on a stable workbench or the ground with the head facing up. Clean the exterior of the head with a rag to remove grass clippings, dirt, and oil. A clean work area reduces the chance of debris entering the spool mechanism during reassembly. If your model has a protective cover over the spool, remove it now using the appropriate screwdriver or Torx driver. Keep all fasteners in a small container so they do not get lost.
Removing the Old Line
Removing the spent line is straightforward but must be done carefully to avoid damaging the spool or retainer. Follow these steps:
- Locate the spool retaining nut or knob on the bottom of the head.
- Using the adjustable wrench or socket, turn the nut counter‑clockwise until it loosens.
- Lift the spool assembly straight up; the spring and retainer will come with it.
- Unwind any remaining line from the spool chambers. If the line is tangled, gently pull it free rather than forcing it.
- Inspect the spool for cracks, warping, or excessive wear. Replace the spool if damage is evident.
- Clean the spool interior with a dry rag; remove any grass buildup that could impede new line feeding.
Set the old line aside for recycling. Many municipalities accept nylon trimmer line in plastics recycling programs.
Measuring and Cutting New Line
Accurate measurement ensures you have enough line for a full load without waste. Most Craftsman manuals specify a total length of 20–30 feet for dual‑line heads (10–15 feet per side) and 15–20 feet for single‑line heads. To measure:
- Lay the new line on a flat surface.
- Use a tape measure to mark the required length for each chamber.
- Cut the line with sharp scissors or a utility knife at the marked points.
- If your spool uses a pre‑cut loop, simply pull the loop to the correct length and cut the excess.
Cutting the line at a slight angle (about 45°) helps the line feed smoothly through the guide eyelets. Avoid frayed ends; they can catch on the spool and cause feeding issues.
Loading the New Line
Loading the line correctly is the most critical step. An improperly wound spool will not feed, leading to frustration and wasted time. The process differs slightly between bump‑feed and fixed‑line heads, but the core principle is the same: wind the line in the direction indicated by the arrows on the spool.
Bump‑Feed Head
- Insert one end of the line into the anchor hole on the spool’s inner wall.
- Wind the line tightly and evenly around the spool, following the arrow direction. Keep tension consistent to avoid loose loops.
- Leave about 6 inches of line protruding from the exit eyelet.
- Repeat for the second chamber if your head is dual‑line.
- Snap the retainer spring back into place, ensuring the line ends sit in the guide slots.
Fixed‑Line Head
- Thread the line through the eyelet on the spool’s outer flange.
- Pull the line through until both ends are equal length.
- Wind both strands simultaneously in the arrow direction, keeping them side‑by‑side.
- Secure the ends in the retaining notches.
After winding, gently tug each line to confirm it is seated properly and will not slip during operation.
Reassembling the Head
With the new line loaded, reattach the spool assembly to the trimmer head.
- Align the spool’s drive hub with the motor shaft.
- Lower the spool onto the shaft, ensuring the spring seats correctly.
- Thread the retaining nut or knob by hand, then tighten with the wrench to the torque specified in the manual (usually 8–10 ft‑lb).
- Reinstall any protective cover you removed earlier.
- Reconnect the spark plug wire or battery.
Double‑check that the spool spins freely by hand. Any resistance indicates misalignment or an over‑tightened nut.
Testing the Trimmer
Before returning to the yard, run a quick test to verify proper line feed and cutting performance.
- Start the engine (or power on the battery unit) and let it idle.
- Engage the throttle to bring the head up to speed.
- Tap the head lightly on a patch of grass or a soft surface. The line should advance a few inches with each tap.
- Trim a small section of vegetation. Observe the cut quality; the line should slice cleanly without excessive vibration.
- If the line does not feed, stop the engine, re‑inspect the spool winding direction, and ensure the line ends are seated in the guide slots.
A successful test confirms that How to Restring a Craftsman Weed Eater? has been executed correctly. If problems persist, consult the troubleshooting section of your manual or contact Craftsman support.
Maintenance Tips
Regular upkeep extends the life of your trimmer and reduces the frequency of restringing.
- Clean the head after each use to prevent grass buildup that can bind the spool.
- Lubricate the spool shaft lightly with a silicone‑based spray every few months.
- Inspect the line for wear before each session; replace when the line diameter has reduced by more than 25 %.
- Store the trimmer in a dry, shaded area. UV exposure degrades nylon line over time.
- Keep a spare spool pre‑wound with line for quick swaps during large jobs.
Following these practices will keep your Craftsman weed eater ready for action whenever you need it.
Common Mistakes to Avoid
Even experienced users can fall into pitfalls that compromise performance.
- Winding the line opposite the arrow direction. This causes the line to feed backward and jam.
- Over‑filling the spool. Excess line creates friction and prevents smooth feeding.
- Using the wrong line diameter. Too thick a line stalls the motor; too thin a line breaks prematurely.
- Neglecting to clean the spool before loading. Debris can cause uneven winding and feed failures.
- Overtightening the retaining nut. This can warp the spool or strip the threads.
Avoiding these errors saves time and prevents unnecessary wear on the trimmer’s drive system.
Comparison of Line Types
Choosing the right line material and shape influences cutting efficiency and line life. The table below compares the most common options for Craftsman trimmers.
| Line Type | Diameter Range | Best For | Durability | Cost (per 50 ft) |
|---|---|---|---|---|
| Round Nylon | .080–.105 in. | General purpose, light grass | Medium | $8–$12 |
| Twisted (Square) Nylon | .080–.095 in. | Thicker weeds, moderate brush | High | $10–$15 |
| Serrated (Star) Nylon | .095–.105 in. | Heavy brush, small saplings | Very High | $12–$18 |
| Co‑polymer (Reinforced) | .080–.105 in. | Professional landscaping, high‑volume use | Maximum | $15–$22 |
Match the line type to the typical vegetation you encounter. For most homeowners, a twisted or serrated line in the .095 in. diameter offers a good balance of cutting power and longevity.
Frequently Asked Questions
How often should I restring my Craftsman weed eater?
Restring when the line length drops below 2 inches on either side or when cutting performance noticeably declines. For average residential use, this occurs every 3–5 hours of operation.
Can I use any brand of trimmer line?
Yes, as long as the diameter matches your model’s specification. However, Craftsman‑branded line is engineered to the exact tolerances of their spools and often feeds more reliably.
Why does my line keep breaking?
Common causes include using a line that is too thin for the vegetation, hitting hard objects (rocks, curbs), or a worn spool eyelet that creates sharp edges. Inspect the eyelets and replace the spool if they are damaged.
What is the difference between bump‑feed and fixed‑line heads?
Bump‑feed heads advance line automatically when you tap the head on the ground. Fixed‑line heads require manual line replacement. Bump‑feed is more convenient for continuous work; fixed‑line heads are simpler and sometimes more durable.
How do I know which direction to wind the line?
Look for molded arrows on the spool body. Wind the line in the direction the arrows point. If arrows are missing, consult the owner’s manual; most Craftsman models wind clockwise when viewed from the bottom.
Can I restring a Craftsman weed eater without removing the spool?
Some newer models feature a quick‑load system that allows line insertion without full spool removal. Check your manual for model‑specific instructions. If your model lacks this feature, full spool removal is required.
