Gathering Your Supplies for Cord Replacement
Before you begin the task of replacing your string trimmer’s pull cord, it is best to gather all the necessary supplies. Doing this beforehand will keep you from stopping and starting. Being prepared will make the entire process more manageable. We’re going to break down the key items you’ll need. This preparation ensures a smoother and more efficient repair.
Essential Tools and Parts
You’ll need a few essential items. First, get a new pull cord. Make sure it’s the right type and length for your specific string trimmer model. You can often find this information in your owner’s manual or by searching online using your trimmer’s model number. You’ll also need a screwdriver set. A flathead and Phillips head screwdriver will probably be needed. Next, get pliers for gripping small parts and a pair of scissors to cut the cord. Gloves will also help keep your hands clean. A small container is useful for keeping track of the small screws and parts you remove. Consider having a new spring on hand. Sometimes, the original spring can be worn or damaged during the repair. Being prepared with a replacement prevents additional setbacks. Also, safety glasses are a good idea. They help protect your eyes from debris.
- New Pull Cord: The replacement cord should be durable and of the correct diameter. This is vital for the pull cord to function correctly and last. Different trimmers require different cord sizes.
- Screwdrivers: You’ll want to have both Phillips head and flathead screwdrivers available. These are used to remove the cover of your trimmer’s engine and the housing that holds the pull cord.
- Pliers: Pliers help you grip small parts, such as knots. They provide better control than fingers alone, making it easier to maneuver the cord.
- Scissors: Scissors are used to cut the new pull cord to the right length. Clean cuts are important for making secure knots.
- Gloves: Gloves provide grip and help prevent injuries, like cuts and scrapes. They also keep your hands clean.
By preparing these tools and parts, you’ll be well-equipped to replace the pull cord. This organized approach minimizes complications and speeds up the repair. Keep everything organized as you go. This will help make sure you don’t lose any small parts during the repair.
Disassembling Your String Trimmer
Before you can
Removing the Trimmer Cover
The first step is usually to remove the cover. This is often held in place by screws. Start by carefully unscrewing these. Use the correct screwdriver for the screws. Place the screws in your small container so you don’t lose them. Some trimmers have clips in addition to screws. Gently release these clips. Once the screws and clips are removed, carefully lift the cover. Pay attention to how the cover fits. Take notes or pictures if needed. This will help you remember how to reassemble the trimmer later. Set the cover aside, ensuring you have enough space to work comfortably.
- Locate the Screws: Most trimmers have screws that secure the cover to the engine housing. These screws are typically found around the edge of the cover. Inspect the entire perimeter of the trimmer.
- Unscrew Carefully: Use the right screwdriver to unscrew the fasteners. A good fit prevents stripping the screws. Place the screws in a secure location.
- Release Clips (if applicable): Some trimmers use clips. These can be small plastic tabs. Gently release the clips. Use a small screwdriver or your fingers to lift them.
- Lift the Cover: Once the screws and clips are removed, gently lift the cover. Be careful not to force it. Observe how the cover fits so you can replace it correctly.
Removing the trimmer cover is the starting point for accessing the pull cord mechanism. This preparation provides you with the access you need for the repair. The next step is to examine the inner parts of the trimmer.
Accessing the Pull Cord Housing
Once you remove the trimmer cover, you’ll see the pull cord housing. This is usually a round or square component. It’s where the pull cord mechanism is located. The housing might be secured by screws. You will need to remove these to access the cord. Sometimes, there might be retaining clips or other fasteners. Take your time to locate and remove these. If there’s a spring-loaded system, be cautious. Springs can be under tension. Carefully release any tension before removing parts. Once you have the housing accessible, you’re ready to remove the old cord. Take pictures as you go, if you like. This will help you get everything back together correctly.
- Identify the Housing: Locate the housing that holds the pull cord. This is usually a distinct part that you’ll need to remove.
- Unscrew Fasteners: Remove any screws or bolts holding the housing in place. Again, put the screws in a safe place.
- Release Retaining Clips: Some housings use clips or other retaining mechanisms. Carefully release these clips. This will release the housing.
- Manage Springs (if present): If there is a spring-loaded system, pay close attention. Release any tension before proceeding. This step is important for safety.
With the housing accessible, you can move forward with replacing the pull cord. Remember to work carefully and note the position of all parts. This will make reassembly easier.
Replacing the String Trimmer Pull Cord
With the trimmer disassembled, it’s time to replace the cord. This involves removing the old cord and installing the new one. This part of the process requires focus. Be sure to pay attention to how the old cord was routed and attached. Careful observation will ensure a smooth replacement. This part can be tricky, but we’ll break it down into easy steps.
Removing the Old Cord
Before installing the new cord, you must remove the old one. This begins by inspecting the existing cord. Locate how it’s anchored inside the housing. There is usually a knot or some form of attachment to secure the cord to the pulley or reel. Use pliers to carefully loosen and remove the old cord from its anchor point. If there is a knot, untie it. If there is a clamp, loosen it. Once the cord is free, pull it out from the housing. Note the path the cord took to get out. Observe how the cord winds around the pulley. This will help you guide the new cord in the correct path. Throw away the old cord.
- Locate the Anchor Point: Find where the old cord is attached inside the housing. It is important to remember this spot for the new cord.
- Loosen the Knot: Use pliers to gently loosen any knot. Be careful not to damage the housing or other parts.
- Remove the Cord: Once the knot is undone, carefully pull the old cord out from the housing. Make sure it comes out completely.
- Observe the Path: Pay close attention to how the cord was routed. The new cord will follow the same path.
Removing the old cord carefully sets the stage for installing the new one. Following these steps helps ensure that you do not damage any internal components of the trimmer. Remember to keep the path of the old cord in mind for the new installation.
Installing the New Cord
With the old cord removed, it’s time to install the new one. Measure the correct length of the new cord. This length usually depends on your trimmer’s model. Consult your owner’s manual for guidance. Thread the new cord through the hole in the housing. This hole is usually where the old cord exited. Then, feed the cord around the pulley or reel inside the housing, following the path of the old cord. Secure the other end of the cord. Tie a knot or use the method provided by your trimmer. Trim any excess cord, leaving enough to grip when starting the trimmer. Test the mechanism to ensure it operates smoothly. Pull the cord several times to confirm that the trimmer’s engine engages correctly.
- Measure the Cord: Measure the new cord. Refer to your owner’s manual to determine the correct length.
- Thread Through the Housing: Feed the cord through the hole in the housing. This hole is the exit point.
- Route the Cord: Route the cord around the pulley or reel. Follow the path the old cord took.
- Secure the Cord: Tie a secure knot or use the method provided by your trimmer to secure the cord. Make sure the knot is tight and will not come loose.
Installing the new cord correctly ensures that the trimmer will start properly. Following these steps helps you install the cord without mistakes. Testing the mechanism is very important. This confirms that all parts are functioning correctly.
Reassembling Your String Trimmer
Once the new cord is installed, it is time to put everything back together. Reassembling your string trimmer is the final step. It requires following the steps in reverse order. Paying close attention to how the parts fit will ensure that the trimmer functions correctly. Careful assembly will prevent problems during operation. This part is about putting it all back together.
Replacing the Pull Cord Housing
Start by replacing the pull cord housing. Carefully position it back into the trimmer. Ensure that the cord is properly seated in its channel or groove. Align the housing with the trimmer’s body. Then, reattach any screws, bolts, or clips that hold the housing in place. Make sure everything is secure and tight. Double-check that the cord moves freely and is not pinched or obstructed. Before tightening the screws completely, test the pull cord a few times. This will make sure that the mechanism works as expected. If everything works well, fully tighten the screws.
- Position the Housing: Align the pull cord housing with the trimmer’s body. Make sure the cord is not pinched.
- Secure with Fasteners: Reattach all screws, bolts, and clips. Tighten them firmly.
- Check for Free Movement: Make sure the pull cord moves freely. Pull and release the cord several times to confirm.

Properly replacing the pull cord housing is important for the trimmer’s overall function. Make sure everything is secure and the cord moves smoothly. This ensures the trimmer is ready for use.
Attaching the Trimmer Cover
The final step is to reattach the trimmer cover. Carefully align the cover with the trimmer housing. Make sure it fits correctly and that all parts are in their proper place. Replace the screws and any clips that were removed. Tighten the screws until they are snug, but avoid over-tightening. Doing so might damage the plastic housing. Once the cover is secure, give the pull cord a few test pulls. This will confirm that the trimmer is fully reassembled and ready to operate. If the trimmer doesn’t start, double-check all connections. Also, make sure that the cord can pull freely. If any problems remain, go back and check your work.
- Align the Cover: Carefully position the cover on the trimmer housing. Make sure the cover fits.
