Understanding Your Ryobi Gas Weed Eater
Before you begin restringing, it helps to know the basic components of your machine. Ryobi gas trimmers typically use a two‑cycle engine that mixes gasoline with oil, powering a rotating shaft that drives the cutting head. The head houses a spool that holds the nylon line; as the line wears, it feeds out automatically or manually depending on the head design.
Engine Basics
The two‑cycle engine requires a precise fuel‑oil mixture, usually 50:1 for modern Ryobi models. Proper mixing ensures lubrication and prevents carbon buildup. Always use fresh gasoline (no more than 30 days old) and a high‑quality two‑cycle oil rated for air‑cooled engines. A clean air filter and a functional spark plug are also essential for reliable starts.
Trimmer Head Types
Ryobi offers several head styles: the fixed‑line head, the bump‑feed head, and the rapid‑load head. Fixed‑line heads hold a pre‑cut length of line that you replace entirely. Bump‑feed heads advance line when you tap the head on the ground. Rapid‑load heads let you insert pre‑wound line cartridges without disassembly. Identifying which head you have determines the exact restringing procedure.
Tools and Materials Needed
Gather the following items before you start: a replacement trimmer line (matching the diameter recommended for your model), a pair of heavy‑duty scissors or a line cutter, a clean rag, a small adjustable wrench or socket set (usually 10 mm), and a pair of gloves for grip and protection. If your model uses a rapid‑load cartridge, you only need the cartridge itself. Having a flashlight helps when working in low light.
Safety Precautions
Safety should never be an afterthought. Turn off the engine and disconnect the spark plug wire to prevent accidental starts. Allow the engine to cool completely if it has been running. Wear safety glasses to shield your eyes from debris, and use hearing protection if you plan to run the trimmer immediately after restringing. Keep the work area clear of bystanders, pets, and flammable materials.
Step-by-Step Guide: How to String a Ryobi Gas Weed Eater
The following ordered steps cover the most common bump‑feed head. If you have a rapid‑load or fixed‑line head, refer to the specific notes in the Choosing the Right Trimmer Line section. (See Also:How To String My Stihl Weed Eater)
Remove the Spool
- Locate the retaining knob or button on the trimmer head. Press or turn it counter‑clockwise to release the spool cover.
- Pull the spool straight out. Note the orientation of any arrows or markings; they indicate the winding direction.
- Inspect the spool for cracks or excessive wear. Replace the spool if damaged.
Cut the Line
- Measure a length of line roughly 10–12 feet (3–3.5 m) for a standard 0.095‑inch diameter. Longer line reduces the frequency of re‑loads.
- Cut the line cleanly with scissors or a line cutter. Avoid frayed ends, which can jam the feed mechanism.
Load the Line
- Find the line‑entry holes on the spool. Insert one end of the line into the first hole, pulling it through until about 6 inches remain outside.
- Wind the line tightly and evenly in the direction indicated by the arrow on the spool. Keep tension consistent to prevent overlapping loops.
- When you reach the second entry hole, thread the remaining line through and pull it snug. Leave a short tail (about 2 inches) protruding.
- If your spool has a dual‑line design, repeat the process for the second line, ensuring both lines are wound in the same direction.
Reassemble the Head
- Place the spool back into the head housing, aligning any notches or tabs.
- Replace the spool cover and secure the retaining knob or button. Turn clockwise until it clicks or feels firm.
- Reconnect the spark plug wire. Prime the engine according to the manufacturer’s instructions and start the trimmer.
- Tap the head lightly on the ground to advance the line. Verify that both lines extend evenly and cut cleanly.
Choosing the Right Trimmer Line
Not all nylon lines are created equal. Selecting the proper diameter, shape, and material dramatically affects cutting efficiency and line life.
Line Diameter
Ryobi gas trimmers typically accept 0.080‑inch, 0.095‑inch, or 0.105‑inch line. Thicker line (0.105) handles heavy brush and thick weeds but puts more strain on the engine. Thinner line (0.080) is ideal for light grass and edging. Consult your owner’s manual for the maximum recommended diameter.
Line Shape
Round line is the most common and works well for general trimming. Twisted, square, or star‑shaped lines have sharper edges that slice through tougher vegetation more cleanly, but they can wear faster and may increase vibration. Multi‑sided lines are a good compromise for mixed‑use yards.
Line Material
Standard nylon is affordable and adequate for most residential tasks. Co‑polymer or reinforced lines add durability and resist UV degradation, extending life in sunny climates. Some premium lines incorporate a core of Kevlar or other high‑strength fibers for extreme conditions.
Comparison Table: Common Ryobi Trimmer Heads
| Head Type | Line Loading Method | Best For | Typical Line Diameter | Ease of Restring |
|---|---|---|---|---|
| Bump‑Feed | Manual wind on spool | General yard work, mixed grass and weeds | 0.080–0.105 in | Moderate |
| Rapid‑Load Cartridge | Pre‑wound cartridge insert | Frequent users wanting quick reloads | 0.095 in (cartridge specific) | Easy |
| Fixed‑Line | Replace entire pre‑cut line | Light edging, low‑maintenance preference | 0.080 in | Easy |
| Dual‑Line Bump‑Feed | Two lines wound on one spool | Heavy brush, faster cutting width | 0.095–0.105 in | Moderate |
Tips for Optimal Performance
- Keep the line tight while winding; loose loops cause jams and uneven feeding.
- Use the correct fuel mix to maintain engine power; a weak engine struggles to spin thick line.
- Clean the head after each use to remove grass buildup that can impede line advance.
- Store the trimmer horizontally with the head facing up to prevent line deformation.
- Replace the spark plug annually for reliable starts, especially after long storage periods.
Common Mistakes and How to Avoid Them
Even experienced users can make errors that reduce cutting efficiency or damage the trimmer.
- Over‑winding the spool – Excess line creates friction and can melt the nylon. Stop winding when the spool is about 80 % full.
- Using the wrong diameter – Too thick a line overloads the engine; too thin a line breaks constantly. Match the manual specification.
- Ignoring the winding direction – Winding opposite the arrow causes the line to feed backward or not at all.
- Skipping the spark plug disconnect – Accidental starts can cause serious injury. Always disconnect before servicing.
- Neglecting to trim the line ends – Frayed ends snag in the feed eyelets. Cut cleanly before loading.
Maintenance After Restringing
After you have successfully restrung the trimmer, a few quick checks keep the tool running smoothly. Run the engine at idle for a minute, then engage the throttle and observe line feed. If the line does not advance, re‑check the spool orientation and ensure the bump knob moves freely. Inspect the air filter and clean or replace it if dirty. Lubricate the drive shaft with a light machine oil if the manufacturer recommends it. Finally, store the trimmer in a dry, ventilated area to prevent corrosion.

Frequently Asked Questions
What line diameter should I use for my Ryobi gas weed eater?
Most Ryobi gas models accept 0.095‑inch line as the standard. Check your owner’s manual; some models allow up to 0.105‑inch for heavy brush, while others limit you to 0.080‑inch for light trimming.
How often do I need to restring the trimmer?
Frequency depends on usage and vegetation type. For average residential lawns, expect to reload every 2–4 hours of cutting time. Heavy brush or commercial use may require daily restringing.
Can I use any brand of trimmer line?
Yes, as long as the diameter and shape match the specifications. Premium co‑polymer or reinforced lines often last longer than budget nylon, but any compatible line will work.
Why does my trimmer line keep breaking?
Common causes include using line that is too thin for the job, hitting hard objects like rocks or curbs, winding the line too loosely, or operating the engine at excessively high RPMs. Adjust technique and line choice accordingly. (See Also:How To Make A Weed Eater Bike)
