Understanding the Ryobi Expand‑It System
The Expand‑It platform is designed around a quick‑connect coupler that lets you swap attachments such as edgers, blowers, and string trimmers without tools. The string trimmer head attaches to the power head via a splined shaft and a locking collar. Inside the head, a spool holds the trimmer line and a spring‑loaded bump feed advances line when you tap the head on the ground.
Most Ryobi Expand‑It trimmer heads are either a fixed‑line head (pre‑wound spool) or a reloadable bump‑feed head. The reloadable version is the one you will restring. It consists of a spool, a cover, a spring, and a line‑guide eyelet. The line feeds out through the eyelet and is cut to length by the built‑in cutter on the guard. Knowing these components helps you identify where the line goes and how the feed mechanism works.
Because the Expand‑It system shares a common shaft diameter across many models, the same restringing procedure applies to the 13‑inch, 15‑inch, and 17‑inch cutting swaths. The only variation is the recommended line diameter, which is usually 0.080 in for lighter duty and 0.095 in for heavier brush. Always check the label on your specific head for the exact specification.
Tools and Materials Needed
Before you begin, gather the following items so the job proceeds without interruptions:
- Replacement trimmer line (correct diameter and length for your model)
- Clean work surface or a sturdy bench
- Gloves to protect your hands from sharp line ends
- Safety glasses to shield eyes from debris
- Small flat‑head screwdriver (optional, for prying the spool cover)
- Scissors or a utility knife for cutting line
- Owner’s manual for reference to model‑specific details
Having the correct line is the most critical material. Ryobi recommends using their branded line, but any high‑quality nylon line that matches the diameter and shape will work. Avoid using metal‑reinforced or wire‑core lines unless the head is explicitly rated for them, as they can damage the feed mechanism.
Safety Precautions
Safety should always come first when working with power equipment. Follow these precautions before you start restringing:
- Disconnect the battery or unplug the power head to eliminate any chance of accidental start‑up.
- Allow the motor and head to cool completely if the unit was recently used.
- Wear safety glasses and gloves throughout the procedure.
- Work in a well‑lit area free of clutter.
- Keep the trimmer line away from children and pets.
These steps protect you from cuts, eye injuries, and unexpected motor engagement. A few seconds of preparation can prevent a serious accident.
Step‑by‑Step Guide to Restring
Follow these numbered steps to reload your Ryobi Expand‑It trimmer head correctly. Each step includes a brief explanation of why it matters.
- Remove the trimmer head from the power head. Depress the locking collar and pull the attachment straight off. This isolates the head and gives you full access to the spool.
- Open the spool cover. Most heads have a press‑tab or a screw. Press the tab or unscrew the cover and lift it away. Keep the spring and any small parts in a safe place.
- Remove the old line. Pull any remaining line off the spool. Discard it properly; old nylon can become brittle and cause feeding problems.
- Cut the new line to length. Measure approximately 20 feet (6 m) of line for a standard 0.095 in spool. Cut cleanly with scissors or a utility knife.
- Insert the line into the anchor hole. Locate the small hole or slot on the spool core. Feed one end of the line through and pull it until about 2 inches remain protruding.
- Wind the line evenly. Turn the spool in the direction indicated by the arrow on the spool (usually clockwise). Keep tension on the line so it lays flat and does not overlap. Fill the spool to the marked fill line, leaving a small gap at the edge.
- Secure the line end. Slip the free end into the notch or slot on the spool flange to hold it in place while you reassemble.
- Reinstall the spool cover. Place the spring back onto the spool shaft, align the cover, and press or screw it shut until it clicks.
- Thread the line through the eyelet. Pull the line from the spool through the guide eyelet on the head housing. Ensure it moves freely without snagging.
- Reattach the head to the power head. Align the splines, push the head onto the shaft, and rotate until the locking collar snaps into place.
- Test the feed. Reconnect the battery, start the trimmer, and gently tap the head on the ground. The line should advance smoothly. Adjust if necessary.
Completing these steps restores full cutting performance and ensures the bump feed operates reliably.
Choosing the Right Trimmer Line
Not all trimmer lines are created equal. The shape, diameter, and material affect cutting efficiency, line life, and feed reliability. Use the comparison table below to match line characteristics to your typical yard conditions.
| Line Type | Shape | Best For | Durability | Feed Reliability |
|---|---|---|---|---|
| Round | Circular cross‑section | Light grass, edging | Moderate | High |
| Square | Four‑sided | Thick weeds, light brush | High | Medium |
| Twisted | Helical twist | Mixed grass and weeds | High | High |
| Serrated | Jagged edges | Heavy brush, tough stems | Very High | Low |
For most residential Ryobi Expand‑It users, a 0.095 in twisted line offers the best balance of cutting power and smooth feeding. If you primarily trim fine grass, a round line reduces drag on the motor. Heavy‑duty users tackling thick brush may prefer square or serrated lines, but be aware that serrated line can wear the feed eyelet faster.
Common Mistakes and How to Avoid Them
Even experienced users can make errors that lead to poor feed or line breakage. Here are the most frequent mistakes and practical fixes:
- Overfilling the spool. Exceeding the fill line causes the line to bind. Stop winding at the indicated mark.
- Winding in the wrong direction. The arrow on the spool shows the correct rotation. Winding backward makes the line feed backward or jam.
- Using the wrong diameter. Too thick a line stresses the motor and may not fit the eyelet; too thin a line wears out quickly. Match the spec on the head label.
- Leaving the line loose on the spool. Slack creates loops that snag during feed. Keep tension while winding.
- Forgetting to secure the line end in the notch. An unsecured end can unwind inside the head, causing a tangled mess.
- Neglecting to clean the eyelet. Debris buildup restricts line movement. Wipe the eyelet with a dry cloth before reassembly.
Avoiding these pitfalls saves you from repeated restringing and extends the life of both the line and the head.
Maintenance Tips for Longer Line Life
Proper care of the trimmer head and line reduces the frequency of restringing and improves cutting quality.
- Store the trimmer in a dry, shaded area. UV exposure degrades nylon over time.
- After each use, wipe the head and eyelet to remove grass sap and dirt.
- Inspect the spool for cracks or warping before each reload. Replace the spool if damaged.
- Lubricate the bump‑feed spring lightly with a silicone spray once per season to keep the feed action smooth.
- Rotate the line spool 180 degrees halfway through the season if you notice uneven wear on one side.
- Keep a spare spool pre‑wound with line for quick swaps during large jobs.
These habits keep the feed mechanism responsive and the line sharp, so you spend more time trimming and less time servicing.
Troubleshooting Common Issues
If the trimmer still misbehaves after restringing, consult this quick reference:
| Symptom | Possible Cause | Solution |
|---|---|---|
| Line does not advance when bumped | Spring missing or broken | Replace spring; ensure it seats correctly on spool shaft |
| Line feeds too much or too little | Incorrect line diameter or worn eyelet | Use spec‑matched line; replace eyelet if grooved |
| Line breaks frequently | Line too thin for workload or hitting hard objects | Upgrade to thicker or tougher line; avoid rocks and curbs |
| Head vibrates excessively | Unbalanced spool or debris in head | Rewind line evenly; clean head interior |
| Motor stalls under load | Line diameter too large for motor rating | Switch to recommended diameter; check battery charge |
Most problems resolve with a careful re‑inspection of the spool, line, and feed components.
Frequently Asked Questions
How often should I restring my Ryobi Expand‑It trimmer?
Restring whenever the line wears down to less than 2 inches beyond the eyelet or when cutting performance drops noticeably. For average residential use, this is typically every 3–5 hours of run time.
Can I use any brand of trimmer line?
Yes, as long as the line matches the diameter (usually 0.080 in or 0.095 in) and the shape is compatible with your head. Ryobi‑branded line is engineered for optimal feed, but quality third‑party lines work well.
Why does the line keep jamming inside the head?
Jams usually result from overfilling the spool, winding in the wrong direction, or debris in the eyelet. Follow the step‑by‑step guide precisely and clean the eyelet before reassembly.
Do I need to remove the head from the power head to restring?
Removing the head gives you the best access and prevents accidental motor start. It is strongly recommended, though some users restring with the head attached if they are very careful.
What is the best line shape for general yard work?
A twisted (helical) line in 0.095 in diameter offers a good mix of cutting efficiency, durability, and reliable feeding for most lawns and light brush.
