Understanding the Bolens BL110 Trimmer Head
The Bolens BL110 features a dual‑line bump‑feed head that advances fresh line each time you tap the head on the ground. The head consists of a spool, a spring‑loaded bump knob, and a retaining cap. Familiarity with these components makes the restringing process smoother because you will know exactly where the line feeds, where the spring sits, and how the cap locks everything in place.
Most BL110 units ship with a 0.080‑inch diameter line, but the head accepts 0.065‑ to 0.095‑inch line depending on the cutting conditions. Thicker line lasts longer in heavy brush, while thinner line spins faster for fine grass. Checking the owner’s manual for the recommended line gauge ensures optimal performance and prevents excessive wear on the motor.
Tools and Materials Needed
- Replacement trimmer line (0.080‑inch recommended, 50‑foot spool)
- Clean rag or shop towel
- Flat‑head screwdriver (for prying the retaining cap if needed)
- Needle‑nose pliers (helpful for threading line through eyelets)
- Safety glasses and gloves
- Workbench or stable surface
Having everything within reach before you start eliminates interruptions and reduces the chance of losing small parts such as the spring or the bump knob.
Safety Precautions
Before any maintenance, disconnect the spark plug wire or remove the battery pack on cordless models. This prevents accidental starts while your hands are near the cutting head. Wear safety glasses to protect your eyes from stray line fragments, and gloves to guard against sharp edges on the spool and cap. Keep the work area well‑lit and free of clutter so you can see the small components clearly.
Removing the Old Line
- Turn the trimmer upside down so the head faces upward.
- Press the bump knob inward and rotate it counter‑clockwise until the retaining cap releases.
- Lift the cap off and set it aside with the spring still seated inside.
- Pull the spent line out of the spool. If the line is tangled, use needle‑nose pliers to gently free it.
- Inspect the spool for cracks or excessive wear; replace the spool if damage is evident.
Removing the old line completely ensures the new line feeds without obstruction and prevents old fragments from jamming the bump mechanism.
Preparing the New Trimmer Line
Cut a length of line approximately 20 feet for a standard dual‑line head. If you prefer a single‑line setup, 10 feet is sufficient. Fold the line in half to locate the midpoint; this midpoint will sit in the spool’s central anchor hole. Some users pre‑stretch the line by pulling it gently between two fixed points for a few seconds, which reduces initial curling and helps the line lay flat on the spool.
Thread each end of the line through the corresponding eyelet on the spool. The eyelets are usually marked with arrows indicating the winding direction—most Bolens heads wind clockwise when viewed from the top. Follow the arrows precisely; winding in the wrong direction causes the line to feed backward and jam.
Step‑by‑Step Restringing Process
- Anchor the midpoint: Insert the folded midpoint into the spool’s center anchor hole. Pull both ends taut so the line sits snugly.
- Wind the first half: Holding the spool steady, wind one end of the line onto the spool following the directional arrow. Keep the wraps tight and even, avoiding overlaps.
- Wind the second half: Repeat the winding process with the other end, filling the opposite side of the spool. Leave about 6 inches of line protruding from each eyelet for the bump feed.
- Secure the line ends: Tuck the short tails into the small retaining slots on the spool rim, or use the built‑in line‑lock tabs if your model has them.
- Reassemble the head: Place the spring back into the bump knob, set the cap over the spool, and press down while turning clockwise until it clicks into place.
- Check free rotation: Spin the spool by hand; it should rotate smoothly without binding.
Each step is designed to keep the line evenly distributed, which prevents vibration and uneven cutting.
Adjusting Line Length and Tension
After reassembly, pull the bump knob gently to verify that line advances. The ideal exposed length is roughly 4‑6 inches on each side. If the line is too short, the head will not cut effectively; if too long, the motor may bog down. Adjust by feeding more line through the eyelets or trimming excess with scissors. Proper tension ensures the bump feed engages cleanly every time you tap the head.
Testing the Trimmer
Reconnect the spark plug wire or reinstall the battery. Start the engine and let it idle for a few seconds. Engage the throttle and tap the head on a patch of grass. The line should extend automatically and cut cleanly. Listen for unusual noises—rattling or grinding indicates a mis‑wound spool or a loose cap. If the line does not feed, stop the engine, re‑inspect the spool, and verify the winding direction.
Comparison Table: Bolens BL110 vs. Other Models
| Feature | Bolens BL110 | Typical 2‑Cycle Competitor | Typical 4‑Cycle Competitor |
|---|---|---|---|
| Engine Type | 2‑cycle, 25 cc | 2‑cycle, 22‑27 cc | 4‑cycle, 25‑30 cc |
| Line Diameter Range | 0.065‑0.095 in | 0.065‑0.095 in | 0.080‑0.105 in |
| Bump‑Feed Mechanism | Dual‑line, spring‑loaded | Dual‑line, spring‑loaded | Single‑line, manual feed |
| Weight (dry) | ≈ 11 lb | ≈ 10‑12 lb | ≈ 13‑15 lb |
| Typical Price Range | $120‑$150 | $100‑$140 | $180‑$250 |
The table highlights why the BL110’s dual‑line bump feed and moderate weight make it a versatile choice for both residential and light commercial use.
Tips for Longer Line Life
- Use the correct line diameter for the job; oversized line stresses the motor and wears faster.
- Store the trimmer with the head facing up to prevent line from deforming under its own weight.
- Keep the spool clean; debris buildup creates friction that shortens line life.
- Avoid cutting hard objects like rocks or metal edging; they cause immediate line breakage.
- Periodically lubricate the bump knob spring with a light machine oil to maintain smooth feeding.
Common Mistakes and How to Avoid Them
- Winding the line in the wrong direction: Always follow the arrow on the spool. Reverse winding causes the line to retract instead of extend.
- Overfilling the spool: Excess line creates bulges that jam the bump mechanism. Leave the recommended 6‑inch tails.
- Skipping the spring inspection: A worn or missing spring prevents the bump knob from returning, leading to manual feeding only.
- Using mismatched line gauge: Too thin a line snaps under load; too thick a line overloads the engine. Stick to the manufacturer’s range.
- Neglecting to secure the line ends: Loose tails can slip out during operation, causing uneven cutting and potential injury.
Frequently Asked Questions
How often should I restring my Bolens BL110?
Restring whenever the line becomes shorter than 3 inches on either side or when cutting performance noticeably declines. For average residential use, this typically occurs every 4‑6 hours of run time.
Can I use any brand of trimmer line?
Yes, as long as the line diameter falls within the 0.065‑0.095 inch range specified for the BL110. Quality brands with low‑memory polymer tend to feed more reliably.
Why does the line keep jamming after I restring?
Jamming usually results from incorrect winding direction, overfilled spool, or a damaged spring. Double‑check the arrow direction, trim excess line, and inspect the spring for cracks.
Is it necessary to replace the spool each time?
Only replace the spool if you see cracks, warping, or excessive wear on the anchor hole. A healthy spool can be reused many times.
Can I convert the BL110 to a single‑line setup?
The head is designed for dual‑line operation. Converting to single‑line reduces cutting width and may unbalance the head, so it is not recommended.
Conclusion
