Why String Replacement Matters
The cutting string on your Makita weed eater is responsible for slicing through grass, weeds, and light brush around your yard. Over time, this string wears down from friction against concrete, stone, and thick plant stems. A dull or damaged string not only reduces cutting efficiency but also puts extra strain on the motor, which can lead to premature wear and costly repairs. Regularly replacing the string ensures clean cuts, prevents unnecessary strain on internal components, and maintains consistent performance throughout the growing season.
Tools and Materials You Will Need
Before starting the process of changing the string on your Makita weed eater, gather the following items:
- New replacement string compatible with your model
- Small flathead screwdriver
- Clean cloth or paper towels
- Soft brush or old toothbrush
- Gloves to protect your hands
- Compressed air or a can of dust remover (optional)
Having these tools ready will make the process smoother and help you avoid unnecessary interruptions once you begin disassembling the trimmer head.
Identifying Your Makita Model Type
Makita produces several different weed eater models, and the string replacement process can vary slightly depending on whether your unit uses a bump-feed system, automatic feed system, or a fixed-line design. Check the model number printed on the motor housing or the operator’s manual. Common Makita string trimmer models include the XRU02Z, XRU15PT1, and ERB18L. Some models use a single line while others use dual lines. Knowing your specific configuration helps you choose the correct replacement string and understand how the spool is assembled.
Bump Feed Systems
Bump feed trimmers release more line when you tap the head against the ground while operating the tool. These systems typically have a spring-loaded spool that must be carefully removed and rewound.
Automatic Feed Systems
Automatic feed models sense when the line is getting short and advance new string automatically. These often require more precise reassembly to ensure proper tension and feeding.
Preparation Before You Begin
Safety comes first when working with power tools. Follow these preparation steps before attempting to change the string on your Makita weed eater:
- Disconnect the battery or spark plug wire to prevent accidental startup.
- Work in a clean, well-lit area where small parts won’t get lost.
- Place a towel or mat on your workspace to protect the tool and catch debris.
- Remove any remaining string from the head by pulling it out manually or cutting it away if it is tangled.
- Consult your owner’s manual for specific disassembly instructions related to your model.
Taking these precautions reduces the risk of injury and ensures you don’t lose important components during the replacement process.
Removing the Old String
With the tool safely powered off, locate the string trimmer head on the end of the shaft. Most Makita models have a cap or cover on top of the head that can be removed by hand or with a screwdriver. Once the cover is off, you will see the spool inside the housing. Press down on the spool and rotate it counterclockwise to release any tension. Pull the old string out of the eyelets on the side of the head. If the string is broken or stuck, use a pair of needle-nose pliers to gently pull it free. Remove the entire spool from the housing if your model allows it, as this makes winding much easier.
Dealing with Retained or Broken String
If pieces of old string remain lodged in the eyelets, use a small screwdriver or pick tool to carefully extract them. Leaving fragments behind can interfere with the new string’s path and cause feeding problems later.
Cleaning the Spool and Housing
Dirt, grass clippings, and debris often accumulate inside the trimmer head housing during regular use. Before installing a new string, clean the spool and housing thoroughly:
- Use a soft brush to scrub away stubborn debris from the spool grooves.
- Wipe down the housing with a damp cloth to remove buildup.
- Blow out any remaining particles with compressed air if available.
- Inspect the eyelets for wear or sharp edges that could damage the new string.
A clean spool ensures smooth winding and reliable string feed performance after reassembly.
Winding the New String
This is the most critical part of learning how to change the string on a Makita weed eater. Follow these steps carefully: (See Also:Can You Use A Weed Eater While Pregnant)
- Cut the correct length of new string according to your model’s specifications. Most Makita trimmers use between 6 and 9 feet of string, but check your manual for exact measurements.
- Locate the anchor hole in the center of the spool. Insert one end of the string through this hole and pull it through until about an inch remains on the inside.
- Hold the loose end to prevent it from pulling back through the hole as you begin winding.
- Winding direction matters. Wind the string in the same direction indicated by arrows molded into the spool. Winding in the wrong direction will cause the string to bind and tangle.
- Keep tension even as you wind. Do not pull too tightly or leave loose loops. The string should lie flat against the spool without overlapping.
- Stop winding when you reach the end of the string, leaving a tail of about one inch.
- Secure the end by pressing it into a small notch or groove near the edge of the spool if present.
For dual-line spools, repeat this process on the second side, ensuring both lines are wound in the correct direction and have equal lengths.
Winding Tips for Smooth Operation
Avoid over-winding the string, as this can create excessive tension that makes it difficult for the line to feed properly. Also, make sure the string lies neatly in the grooves and does not cross over itself, which causes tangles during use.
Reinstalling the Spool
Once the new string is properly wound, carefully place the spool back into the trimmer head housing:
- Align the spool correctly with the housing, making sure any tabs or notches line up.
- Press the spool down firmly until it seats fully in place.
- Rotate the spool clockwise to reapply tension to the spring mechanism if applicable.
- Reinstall the cap or cover and tighten any screws or locking mechanisms.
- Pull the string through the eyelets until both ends are even and extend approximately 6 inches beyond the head.
Double-check that the spool rotates freely and that the string feeds smoothly before operating the tool.
Testing the Weed Eater Operation
After reassembly, test the string feed mechanism:
- Turn the tool back on or reconnect the battery.
- Activate the trimmer briefly and observe how the string extends.
- If using a bump feed system, tap the head lightly against a hard surface to confirm the string releases properly.
- For automatic feed models, check that the line advances without manual intervention.
- Look for any signs of binding, uneven feeding, or excessive vibration.
If problems occur, power off the tool immediately and review the winding and installation steps to identify any errors.
String Types Comparison
Not all trimmer strings are created equal. Here is a comparison of common string types available for Makita weed eaters:
| String Type | Material | Best For | Durability | Price Range |
|---|---|---|---|---|
| Standard Nylon | Nylon | Light grass and weeds | Moderate | Low |
| Copolymer | Nylon copolymer | Medium-duty trimming | High | Medium |
| Triple-String | Three-ply nylon | Heavy weeds and light brush | Very High | High |
| Braided Line | Polyester or nylon braid | Thick brush and tough jobs | Extremely High | High |
| Round vs. Square | Shape variation | Round for general use, square for aggressive cutting | Varies | Low to Medium |
Choosing the right string depends on your trimming needs and frequency of use. For most residential applications, a standard copolymer round string offers an excellent balance of durability and affordability.
Tips and Best Practices
Follow these recommendations to get the most out of your string replacement efforts:
- Always disconnect power before beginning any maintenance work.
- Keep a spare spool pre-wound so you can quickly swap out a worn one during heavy trimming sessions.
- Store replacement string in a cool, dry place to prevent moisture damage or degradation.
- Check the string regularly during use and replace it before it becomes too short to cut effectively.
- Use the correct gauge and length specified by Makita for your model to avoid feeding issues.
- Wind the string evenly and in the correct direction every time to prevent tangles.
- Clean the housing periodically to maintain optimal performance and prevent premature wear.
These simple habits will extend the life of your trimmer and reduce the frequency of string changes over time.
Common Mistakes to Avoid
Even experienced users sometimes make errors when changing the string on their Makita weed eater. Here are the most frequent mistakes and how to avoid them:
- Winding the string backwards – Always follow the directional arrows on the spool to ensure proper feed.
- Using the wrong string thickness – Check your manual for the correct diameter to prevent jamming or poor performance.
- Over-tightening the spool – Excessive tension can cause the string to break or feed inconsistently.
- Skipping the cleaning step – Debris inside the housing leads to faster wear and feeding problems.
- Pulling the string too tight during installation – Leave enough slack so the line can extend freely when needed.
- Not testing after reassembly – Always verify that the string feeds smoothly before returning to work.
Avoiding these pitfalls will save you time and frustration and keep your Makita weed eater running reliably.
Troubleshooting Problems
If the string isn’t feeding properly after replacement, consider these troubleshooting steps: (See Also:What Oil For Echo Weed Eater)
- String won’t come out of the eyelets – Make sure the spool is seated correctly and the string is threaded through the proper channels.
- String feeds too quickly or tangles – Check that the winding direction matches the spool arrows and that tension is even.
- Line breaks frequently – You may be using the wrong gauge or a low-quality string; switch to a heavier-duty option.
- Bump feed doesn’t release line – Ensure the spring is properly seated and the spool rotates freely.
- Automatic feed doesn’t activate – Verify that the sensor or mechanism is clean and unobstructed.
Refer to your owner’s manual for model-specific troubleshooting guidance if these general tips don’t resolve the issue.
When to Replace String More Often
Certain conditions call for more frequent string changes. Replace the string sooner rather than later if you notice:
- The line appears frayed, cracked, or unevenly worn.
- Cuts become inconsistent or require multiple passes.
- The string tangles or knots frequently during use.
- You’re working in areas with a lot of hard surfaces like concrete or stone.
- You’re trimming thick weeds or light brush regularly.
Proactive replacement prevents damage to the trimmer head and ensures clean, efficient cuts every time.
