Learning how to string a Ryobi trimmer correctly saves time and frustration when tackling yard work. A properly loaded trimmer head ensures consistent feeding, preventing frustrating line jams and breaks mid-task. This guide walks through the process step-by-step for both the bump feed and automatic feed models.
Identifying Your Ryobi Trimmer Feed System
Before beginning, determine which feed mechanism your specific model uses. Ryobi offers trimmers with a simple bump feed system, where you manually tap the head to advance line, and others with a more complex automatic or semi-automatic feed. Checking your user manual is the most reliable method, but you can usually identify the system by looking at the trimmer head itself; a single chamber with holes suggests bump feed, while a dual chamber or complex gearbox often indicates an automatic system.
Gathering Necessary Tools and Line
Using the correct line diameter is critical for optimal performance and to prevent damage to the trimmer head. Consult your Ryobi trimmer’s specifications, typically found in the manual or on a sticker near the motor, for the recommended diameter, usually between .065 and .095 inches. You will also need a pair of scissors or a sharp utility knife for cutting the line and a spool of compatible trimmer line, either nylon monofilament or a specialized formula designed for your specific conditions.
Step-by-Step: Stringing a Bump Feed Trimmer Head
The bump feed system is the most common and involves manually advancing the line. Follow these steps carefully for a secure installation.
Turn off the trimmer and disconnect the spark plug wire to ensure it cannot start accidentally during maintenance.
Remove the trimmer head cover by pressing the tabs or unscrewing the locking collar, depending on your model.
Cut a length of trimmer line approximately 10-12 feet long for a single head replacement.
Thread each end of the line through the holes on the trimmer head spool, following the directional arrows molded into the plastic.
Overlap the two ends by about 4-6 inches and secure them loosely together with a small piece of tape or your finger.
Reinsert the spool into the head and secure the cover, ensuring the tape is pulled tight to create the necessary tension.
Finally, hold the head a few inches above the ground and tap the handle on the ground several times to feed the line to the correct length for cutting.
Step-by-Step: Handling Automatic Feed Systems
Some high-end Ryobi trimmers feature a more complex automatic feed system that requires a different approach. Do not force manual bumping actions on these units as it can break the mechanism.
Always refer to your specific model’s manual, as the gear-driven systems can vary significantly in disassembly procedures.
Typically, you will need to release a locking mechanism or remove a side plate to access the internal spool cartridge.
Remove the old cartridge and replace it with a new, factory-loaded spool designed for your trimmer model.
Ensure the cartridge clicks into place securely before reassembling the housing.
Test the feed mechanism by engaging the line advancement button; you should feel consistent tension without the line slipping.
Common Mistakes to Avoid
Even with the correct procedure, certain errors can lead to poor performance. Using line that is too thick is a primary cause of jamming, so always verify the diameter rating. Additionally, improperly securing the spool allows it to spin freely, which prevents line from feeding correctly. Air filters clogged with grass debris can also create a vacuum that inhibits line advancement, so check this component regularly during the season.
