How To Restring Greenworks 80v Trimmer

Restringing your Greenworks 80V trimmer is a task you'll encounter regularly, especially if you maintain a lawn or garden. Learning to do it yourself saves you time and money compared to professional servicing. This guide provides a straightforward, step-by-step approach.

Preparing Your Trimmer

First, disconnect the battery from the trimmer. This prevents accidental starts and ensures safety.

Locate the trimmer head. Examine it to determine the type of head you have – typically bump-feed or automatic-feed. This affects the restringing process.

Clean the trimmer head. Remove any grass, debris, or old line remnants from the head. A small brush or screwdriver can help.

Restringing a Bump-Feed Trimmer Head

Disassembling the Head:

Find the release tabs or buttons on the trimmer head. Press them simultaneously and pull the spool cover off. In some cases, you might need to unscrew the spool retainer knob.

Remove the empty spool from the trimmer head. Take note of the spool's orientation and how the old line was wound. This serves as a reference.

Winding the New Line:

Cut a length of trimmer line appropriate for your trimmer. Consult your Greenworks 80V trimmer manual for the recommended line diameter and length. Using the wrong line can damage your trimmer. Typically, 20-25 feet is sufficient, but refer to your manual.

Locate the small hole or anchor point on the spool. Insert one end of the trimmer line into this hole and wind the line tightly and evenly around the spool. Follow the directional arrows (if present) on the spool. Make sure the line is neatly layered and doesn't overlap excessively. Overlapping can cause the line to jam.

Leave several inches of line unwound. This will be used to thread the line through the eyelets on the trimmer head.

Reassembling the Head:

Thread the ends of the trimmer line through the eyelets on the trimmer head. Ensure each end goes through its designated eyelet. Some heads have a single eyelet; in this case, both ends of the line pass through it.

Align the spool with the trimmer head housing. Make sure it sits properly. Reattach the spool cover, pressing it firmly until it clicks into place. If there's a spool retainer knob, tighten it securely.

Test the line. Gently pull on both ends of the trimmer line to ensure they advance smoothly. If the line doesn't advance, recheck the winding and reassembly steps.

Restringing an Automatic-Feed Trimmer Head

Automatic-feed trimmer heads are typically easier to restring.

Removing the Old Spool (If Necessary):

Some automatic-feed heads allow you to simply insert a pre-wound spool. If you are restringing the existing spool, follow the disassembly instructions similar to the bump-feed head, releasing tabs or unscrewing a retainer.

Remove the old spool and clear any debris.

Inserting a Pre-Wound Spool (If Applicable):

If you're using a pre-wound spool, simply align it with the trimmer head housing. The spool should click or snap into place. Ensure it's securely seated.

Winding a New Line (If Necessary):

If you're winding the line yourself, the process is largely the same as for a bump-feed head. Cut the appropriate length of line, anchor it to the spool, and wind it tightly and evenly, following any directional arrows.

Reassembling the Head:

Thread the end(s) of the trimmer line through the eyelet(s) on the trimmer head.

Align the spool and reattach the cover. Listen for a click or snap to confirm it's properly secured.

Test the automatic feed mechanism. Turn the trimmer on briefly (away from anything that could be damaged). The line should automatically advance. If it doesn't, consult your trimmer manual for troubleshooting steps.

Tips for Effective Restringing

• Use the Right Line: Always use the trimmer line recommended by Greenworks for your 80V model. Using the wrong line diameter can cause feeding problems or even damage the motor.
• Wind Tightly and Evenly: Loose or uneven winding can cause the line to tangle and break. Take your time and ensure the line is neatly layered on the spool.
• Avoid Overfilling: Don't overfill the spool with line. This can also lead to tangling and feeding problems. Refer to your manual for the maximum line capacity.
• Inspect the Eyelets: Check the eyelets for wear or damage. Sharp edges can fray the line and cause it to break prematurely. Replace worn eyelets if necessary.
• Keep it Clean: Regularly clean the trimmer head to remove debris and prevent jams.
• Store Line Properly: Store your trimmer line in a cool, dry place. Avoid direct sunlight, which can degrade the line and make it brittle.

Knowing how to restring your Greenworks 80V trimmer not only saves you money but also empowers you to maintain your yard efficiently. You can quickly address issues like broken lines without interrupting your work. This skill translates into a more professional-looking lawn and a better overall gardening experience. Furthermore, understanding the mechanics of your trimmer allows you to diagnose and potentially fix other minor issues, extending the life of your tool.

By mastering this basic maintenance task, you gain a deeper understanding of your equipment, fostering self-reliance and preventing costly repairs down the road.

Troubleshooting Common Issues

Line Breaks Frequently: This could be due to using the wrong type of line, worn eyelets, or cutting too close to hard surfaces. Check these factors and adjust your technique accordingly.

Line Won't Advance: This can be caused by tangled line on the spool, an overfilled spool, or a faulty automatic feed mechanism. Disassemble the head, check for tangles, and ensure the spool isn't overfilled. If the automatic feed is still not working, consult your manual for specific troubleshooting steps.

Trimmer Head is Difficult to Open: Ensure you're pressing the release tabs or unscrewing the retainer correctly. If the head is stuck due to debris, try gently cleaning around the tabs or retainer with a brush and lubricant. Avoid forcing the head open, as this can damage the components.
