This guide will walk you through each step of the process, helping you perform the replacement with confidence.
Tools and Materials Needed
Before starting the replacement process, it’s important to gather all the necessary tools and materials. This ensures a smooth and efficient replacement procedure:
Replacement Trimmer String: Obtain a replacement string that is compatible with the Ryobi 18V Cordless Trimmer. The string should match the thickness and type recommended in the user manual.
Screwdriver: A Phillips head or flathead screwdriver, depending on the type of screws securing your trimmer head.
Gloves: While optional, wearing gloves can protect your hands from sharp edges and debris.
Scissors or Wire Cutters: Useful for cutting the new string to the correct length.
Step-by-Step Instructions
1. Prepare the Trimmer
Turn Off and Unplug
Safety Precautions: Begin by ensuring that the trimmer is turned off. If your trimmer is cordless, remove the battery to eliminate the risk of accidental activation during the string replacement process. This step is crucial for your safety and prevents any potential accidents.
Inspect the Trimmer Head
Examine the Components: Take a close look at the trimmer head to understand its structure and how the string is loaded. This knowledge will guide you in disassembling the trimmer head and handling the string properly. Familiarize yourself with any markings or instructions on the trimmer head that indicate how to load the string.
2. Remove the Trimmer Head
Locate the Fastening Mechanism
Identify How It’s Secured: Different models may use different methods to secure the trimmer head. It could be fastened with screws or held in place by a locking mechanism. Check the user manual for details specific to your model.
Remove Screws or Disengage Lock
Screws: Use the appropriate screwdriver to carefully remove the screws holding the trimmer head in place. Keep the screws in a safe location, as you’ll need them to reassemble the trimmer head later.
Locking Mechanism: If your trimmer head is secured by a locking mechanism, follow the instructions in the manual to disengage it. This might involve pressing a release button or turning a knob.
Take Off the Trimmer Head
Careful Removal: With the screws removed or the locking mechanism disengaged, gently lift off the trimmer head from the trimmer shaft. Be cautious to avoid damaging any components or displacing small parts that might be inside the trimmer head.
3. Remove the Old String
Locate the Old String
Identify the String’s Position: The old string will be wound around the spool inside the trimmer head. Inspect how the string is threaded through the spool and any retaining mechanisms that hold it in place.
Remove the Old String
Unwind or Cut: If the spool is removable, take it out of the trimmer head and unwind the old string. Alternatively, if the spool is not removable, use scissors or wire cutters to cut the old string. Be sure to dispose of the old string properly.

4. Install the New String
Prepare the New String
Cut to Length: Measure and cut the new string to the length specified in your trimmer’s manual. Generally, about 10-15 feet of string is required, but the exact length may vary depending on your model.
Wind the String onto the Spool
Proper Winding Technique: Place the new string onto the spool. Follow the winding direction indicated on the spool to ensure the string is wound correctly. Wind the string tightly and evenly to prevent tangles and ensure smooth operation. It’s important to avoid overlapping or crossing the string to maintain proper function.
Thread the String
Secure Placement: After winding the string, thread the ends through the eyelets or holes on the trimmer head. This step is crucial for securing the string and preparing it for use. Make sure the string is threaded through all the necessary guides and is positioned correctly.
5. Reassemble the Trimmer Head
Replace the Spool
Reinstall the Spool: If you removed the spool, place it back into the trimmer head. Ensure that it is seated properly and aligned with any guides or slots inside the trimmer head.
Reattach the Trimmer Head
Align and Secure: Align the trimmer head with the trimmer shaft and reattach it. If your model uses screws, insert and tighten them securely. For models with a locking mechanism, re-engage the lock according to the manufacturer’s instructions.
Secure Fastenings
Final Checks: Ensure all screws are tightened properly or that the locking mechanism is fully engaged. This prevents any loose components and ensures that the trimmer head is firmly attached to the trimmer shaft.
6. Test the Trimmer
Reinsert the Battery
Power Up: Insert the battery back into the trimmer and ensure it is properly seated. This step prepares the trimmer for testing and ensures it has the power to operate.
Test the String
Run the Trimmer: Turn on the trimmer and let it run at a low speed to test the new string. Observe the string feeding mechanism and ensure that it operates smoothly without any tangles or issues. Check for any irregularities in the string’s performance and make adjustments if necessary.
Tips and Safety Precautions
Read the Manual: Always refer to the user manual specific to your Ryobi 18V Cordless Trimmer model for detailed instructions and safety information.
Use the Correct String: Ensure that the replacement string is the correct type and thickness for your trimmer. Using the wrong string can affect performance and may damage the trimmer.
Wear Safety Gear: While optional, wearing gloves and safety glasses can protect you from sharp edges and debris during the replacement process.
Regular Maintenance: Regularly check the condition of the trimmer string and replace it as needed to maintain optimal performance. Keeping your trimmer in good condition will extend its lifespan and ensure efficient operation.
