How to Change Line on a Bump Feed String Trimmer

Introduction

Welcome to Fire Appliance's guide on how to change line on a bump feed string trimmer. If you are a homeowner or a professional landscaper, knowing how to properly replace the line on your string trimmer is essential for maintaining a well-manicured lawn. In this comprehensive guide, we will walk you through the step-by-step process, providing useful tips and insights to make the task hassle-free and efficient.

Why is Line Replacement Important?

Regular maintenance, including line replacement, ensures your string trimmer performs optimally, delivering clean and precise cuts. Over time, the trimmer line may wear out or break, reducing its cutting effectiveness. By replacing the line, you can maintain optimal cutting performance, saving time and effort during your trimming tasks.

Choosing the Right Line

Before we dive into the line replacement process, it's important to select the right string trimmer line for your specific needs. Different types of line offer varying cutting capabilities, so consider the thickness and material when making your choice.

Nylon Line

Nylon line is the most common and versatile option, suitable for general trimming and maintenance tasks. It is durable, affordable, and delivers excellent cutting performance under normal conditions.

Commercial-Grade Line

If you have more demanding cutting tasks, such as trimming thick grass or dense weeds, consider using commercial-grade line. This line is thicker and stronger, providing enhanced cutting power and durability. However, keep in mind that it may be more expensive than standard nylon line.

Step-by-Step Guide: Changing Line on a Bump Feed String Trimmer

Step 1: Preparation

Start by turning off the string trimmer and disconnecting the spark plug to ensure your safety. Place the trimmer on a flat surface and allow it to cool down if it was in use recently. This will prevent any accidental starts.

Step 2: Locate the Spool

Identify the spool head on your bump feed string trimmer. It is usually located at the bottom of the trimmer head and can be accessed by unscrewing the bump knob.

Step 3: Remove the Old Line

With the spool exposed, carefully remove the old line by unwinding it or cutting it, depending on the trimmer's design. Be cautious when handling sharp ends and dispose of the old line properly to avoid injuries.

Step 4: Measure and Cut New Line

Take the new string trimmer line and measure an appropriate length based on your trimmer's specifications. Cut the line to size using sharp scissors or a utility knife. Make sure to follow the manufacturer's guidelines for the correct line length.

Step 5: Load the New Line

Insert the freshly cut line into the line-loading holes or notches on the spool. Ensure it is properly aligned and follow any directional arrows if provided. Make sure to leave enough excess line for efficient bump feeding.

Step 6: Wind the Line

Carefully wind the new line onto the spool, following the direction of the arrow indicators. Ensure it is evenly distributed and avoid overlapping the line to prevent tangles or jams during operation.

Step 7: Reassemble the Trimmer

Once the line is securely wound, reattach the spool to the trimmer head, making sure it is correctly seated. Tighten the bump knob by turning it clockwise, ensuring a snug fit but not overtightening.

Step 8: Test and Adjust

Before using the trimmer, give the bump feed mechanism a few gentle taps against the ground to release the line. Adjust the line length if necessary, following the trimmer's specific instructions. Finally, reconnect the spark plug and you are ready to go!

Tips and Best Practices

• Always refer to your string trimmer's manual for specific instructions and guidelines.
• Consider wearing protective gloves and eyewear while handling and replacing the line.
• Inspect the spool head regularly for any signs of damage or wear and replace it if needed.
• Clean the trimmer after use to remove any grass or debris accumulation, ensuring optimal performance.
