Understanding Trimmer Line Basics
Line Diameter
The diameter of the line is the most critical specification. Makita trimmers typically accept lines ranging from 0.065 inch (1.65 mm) up to 0.095 inch (2.41 mm). A thinner line (0.065–0.080 inch) spins faster, producing a cleaner cut on light grass and weeds, while a thicker line (0.090–0.095 inch) delivers more mass for tackling dense brush and small saplings. Always check the owner’s manual for the maximum diameter the spool can accommodate; exceeding it can cause the head to jam or the motor to overheat.
Line Shape
Trimmer line comes in several cross‑sectional shapes: round, square, star, and twisted. Round line is the most common and works well for general lawn maintenance. Square and star shapes have sharp edges that slice through thicker stems more efficiently, reducing the effort required from the motor. Twisted line offers a compromise, providing a bit of cutting edge while maintaining the durability of round line. Makita’s dual‑feed heads accept most shapes, but the spool’s internal geometry may favor round or slightly twisted profiles for smooth feeding.
Line Material
Most consumer‑grade lines are made from nylon copolymer, which balances flexibility and wear resistance. Professional‑grade lines often incorporate a higher‑percentage of nylon 6,6 or add a small amount of polymer additives for increased abrasion resistance. Some premium lines feature a co‑extruded core with a tougher outer sheath, extending life when cutting abrasive surfaces like concrete edges or gravel. For a Makita weed eater used primarily on residential lawns, standard nylon copolymer line is sufficient and more cost‑effective.
Makita Weed Eater Models and Recommended Line Sizes
Makita produces a range of cordless and corded string trimmers. The table below summarizes the most popular current models and the line diameters they support. Always verify the exact specification on the model’s label or manual, as regional variations can exist.
| Model | Power Source | Max Line Diameter | Recommended Diameter (General Use) | Spool Type |
|---|---|---|---|---|
| XRU15PT1 | 18V LXT Battery | 0.095 in (2.41 mm) | 0.080 in (2.03 mm) | Bump‑feed, dual‑line |
| XRU02Z | 18V LXT Battery | 0.080 in (2.03 mm) | 0.065 in (1.65 mm) | Fixed‑line, single‑line |
| EM2650LH | AC Corded | 0.095 in (2.41 mm) | 0.080 in (2.03 mm) | Bump‑feed, dual‑line |
| XRU07Z | 18V LXT Battery | 0.095 in (2.41 mm) | 0.090 in (2.29 mm) | Rapid‑load, dual‑line |
| XRU04Z | 18V LXT Battery | 0.080 in (2.03 mm) | 0.065 in (1.65 mm) | Fixed‑line, single‑line |
Notice that the higher‑voltage 18V LXT models (XRU15PT1, XRU07Z) can handle the thickest 0.095 inch line, making them suitable for heavier brush. The compact XRU02Z and XRU04Z are designed for lighter duty and perform best with 0.065 inch line. The corded EM2650LH sits in the middle, offering the flexibility of a bump‑feed head with a maximum of 0.095 inch.
How to Determine the Correct Line Size for Your Makita
If you have misplaced the manual, you can still identify the proper line size by following these steps:
- Locate the model number. It is usually printed on a label near the motor housing or on the battery compartment.
- Check the spool housing. Many Makita heads have a small molded indicator showing the maximum line diameter (e.g., “MAX 2.4 mm”).
- Measure the existing line. If a piece of line is still on the spool, use a caliper or a ruler with millimeter markings to measure its thickness.
- Consult the manufacturer’s website. Enter the model number on Makita’s support page to download the spec sheet.
- Match the diameter to your cutting needs. For routine lawn edging, choose the lower end of the allowed range; for thick weeds or small brush, move toward the upper end.
- Select the line shape. Round line is safest for all models; square or star shapes are acceptable on bump‑feed heads but may cause feeding issues on fixed‑line heads.
- Purchase the correct spool length. Most Makita spools hold 15–20 feet of line; buying a bulk spool (50–100 feet) lets you refill multiple times.
Following this process eliminates guesswork and ensures you stay within the trimmer’s design limits. (See Also:What Size Weed Eater String For Dewalt)
Installing New Trimmer Line on a Makita Weed Eater
Proper installation prevents line breakage, uneven feeding, and head damage. The steps below apply to the common bump‑feed dual‑line heads found on models like the XRU15PT1 and EM2650LH.
- Power off and disconnect. Remove the battery or unplug the cord to avoid accidental starts.
- Remove the spool cover. Press the release tabs on the sides of the head and lift the cover off.
- Take out the empty spool. Pull the spool straight out; note the orientation of the line guide slots.
- Cut the new line to length. Most Makita spools require two equal lengths of about 10 feet each. Measure and cut with sharp scissors.
- Insert the first line. Feed one end into the lower anchor hole, wind the line in the direction indicated by the arrow on the spool (usually clockwise). Keep tension even and avoid overlapping.
- Insert the second line. Repeat for the upper anchor hole, winding in the same direction. Ensure both lines sit side‑by‑side without crossing.
- Leave a short tail. Allow about 6 inches of line to protrude from each exit hole; this tail will be trimmed automatically on first use.
- Reinstall the spool. Place the spool back into the head, aligning the line guides with the exit holes.
- Replace the cover. Snap the cover back until the tabs click securely.
- Test feed. Reconnect power, start the trimmer, and tap the head on the ground to advance line. Verify both lines extend evenly.
For fixed‑line single‑line heads (XRU02Z, XRU04Z), the process is similar but only one line is wound, and the head does not have a bump‑feed mechanism; you simply pull the line through the eyelet until the desired length is reached.
Common Mistakes When Choosing or Installing Line
Even experienced users can fall into traps that reduce performance or damage the trimmer. Below are the most frequent errors and how to avoid them.
- Using line that is too thick. Exceeding the maximum diameter forces the motor to work harder, leading to overheating and premature wear. Always stay at or below the rated maximum.
- Mixing line shapes on a dual‑line head. Combining round and square line creates uneven drag, causing one line to feed faster than the other. Stick to a single shape per spool.
- Over‑winding the spool. Packing too much line prevents the bump‑feed mechanism from releasing line cleanly. Follow the manufacturer’s recommended length (usually 10 feet per line).
- Ignoring the winding direction. Winding opposite to the arrow causes the line to unwind during operation, resulting in immediate line loss.
- Leaving long tails after installation. Excess tail length can snag on the guard or the ground, pulling the line out of the spool. Trim tails to the recommended 6 inches.
- Using damaged or brittle line. Old line that has been exposed to UV light becomes brittle and snaps easily. Store line in a cool, dark place and replace it annually.
Tips and Best Practices for Optimal Performance
Applying a few simple habits can extend line life and improve cutting quality.
- Match line to the job. Use 0.065 inch round line for weekly lawn edging; switch to 0.090 inch square line when clearing overgrown fields.
- Keep the cutting head clean. Grass buildup around the spool housing adds friction and can cause the bump‑feed to stall. Brush the head after each use.
- Tap gently. A light tap on the ground advances line smoothly; aggressive pounding can damage the feed spring.
- Rotate the line periodically. If you notice one side wearing faster, remove the spool and swap the two lines to even out wear.
- Lubricate the feed spring. A drop of light machine oil on the spring once a season keeps the bump action crisp.
- Store the trimmer horizontally. Hanging the tool by the handle can cause the line to settle unevenly in the spool, leading to feeding problems.
- Use genuine Makita spools when possible. Aftermarket spools sometimes have slightly different dimensions that affect line tension.
Troubleshooting Line Feeding Issues
If the line refuses to advance or feeds unevenly, run through this checklist before assuming the head is broken.
- Check for line jams. Open the head and look for tangled line or debris lodged in the feed channel.
- Verify line diameter. A line that is too thick for the head will bind; a line that is too thin may slip past the feed teeth.
- Inspect the bump‑feed spring. A weakened or broken spring will not push the spool forward. Replace the spring if it feels soft.
- Ensure the spool spins freely. Remove the spool and spin it by hand; resistance indicates a bent spindle or worn bearings.
- Confirm correct winding direction. Re‑wind if the line was installed opposite the arrow.
- Examine the exit holes. Burrs or melted plastic can snag the line. Lightly file any rough edges.
- Test with a fresh spool. If the problem persists with a new, correctly wound spool, the head assembly may need replacement.
Maintenance and Storage of Trimmer Line
Proper care of both the line and the trimmer head prolongs service life and keeps cutting performance consistent. (See Also:How To Add String To Homelite Weed Eater)
- Clean after each use. Remove grass clippings from the head, guard, and motor vents with a brush or compressed air.
- Inspect the line for wear. Before each session, pull a few inches of line out and look for fraying, flattening, or discoloration.
- Replace line annually. Even if the line looks intact, UV exposure degrades nylon over time. A fresh spool each season is inexpensive insurance.
- Store line in a sealed container. A plastic bin with a lid protects bulk line from moisture and sunlight.
- Keep the trimmer in a dry environment. Humidity can cause the motor bearings to rust and the line to absorb water, making it heavier and less efficient.
- Charge batteries correctly. For cordless models, store batteries at 40‑60 % charge and avoid leaving them on the charger indefinitely.
Frequently Asked Questions
What size line for Makita weed eater is best for general lawn care?
For most residential lawn tasks, a 0.080 inch (2.03 mm) round nylon line provides a good balance of cutting speed and durability on Makita 18V LXT and corded models.
Can I use square or star‑shaped line on my Makita trimmer?
Yes, bump‑feed dual‑line heads accept square and star profiles. However, fixed‑line single‑line heads may experience feeding issues with non‑round shapes, so round line is recommended for those models.
How often should I replace the trimmer line?
Replace the line at the start of each mowing season or whenever you notice excessive breakage, fraying, or a noticeable drop in cutting performance.
Why does my line keep breaking during use?
Frequent breakage usually indicates the line is too thin for the vegetation, the line is old and brittle, or the head is feeding too much line at once. Upgrade to a thicker diameter, use fresh line, and ensure the bump‑feed spring is functioning correctly.
Can I refill a Makita spool with bulk line instead of buying pre‑wound spools?
Absolutely. Bulk line (50–100 feet) is cost‑effective. Just cut the required length, wind it following the arrow direction, and leave the recommended tail length. (See Also:How To Thread A Craftsman Weed Eater Spool)
