How to Change Strimmer Wire

Before we delve into the step-by-step process, it’s essential to familiarize ourselves with the basics of strimmer wire.

Strimmer wire, also known as trimmer line or strimmer line, is a durable and flexible string used to cut grass, weeds, and other vegetation in your garden or lawn. It comes in various shapes and thicknesses, designed to fit different strimmer heads and cutting requirements.

There are two primary types of strimmer wire available:

Round Strimmer Wire: This type of strimmer wire features a circular cross-section and is ideal for general trimming tasks. It works well on grass and light weeds, making it suitable for most domestic applications.

Twisted Strimmer Wire: As the name suggests, this wire has a twisted shape that offers increased cutting power. It is more effective against tougher vegetation like dense weeds and small shrubs, making it suitable for professional landscaping projects.

Now that we’ve covered the basics let’s move on to the step-by-step guide on how to change strimmer wire effectively.

Gather the Required Tools and Safety Equipment: Before starting the strimmer wire replacement process, ensure you have all the necessary tools and safety equipment. You will need a replacement strimmer wire spool that matches your strimmer’s specifications, gloves, safety goggles, and a pair of pliers.

Power Off and Disconnect the Strimmer: For safety reasons, always ensure that the petrol strimmer is powered off and disconnected from the power source before attempting any maintenance or replacement.

Locate the Strimmer Head: The strimmer head is the part of the tool that holds the strimmer wire. Depending on the strimmer model, it may have a bump feed system or require manual winding of the wire.

Remove the Old Strimmer Wire: If the strimmer wire is used up or broken, carefully remove the remnants from the strimmer head. Use the pliers to detach any tangled pieces.

Prepare the Replacement Strimmer Wire: Take the new strimmer wire spool and measure an appropriate length for your strimmer head. Typically, a length between 8 to 10 feet is sufficient for most strimmers.

Insert the Replacement Strimmer Wire: Following the manufacturer’s instructions, insert the new strimmer wire into the strimmer head. Make sure it is securely seated in the head’s notches or holes.

Wind the Strimmer Wire: If your strimmer requires manual winding, carefully wind the replacement wire around the head in the direction indicated by the arrow. Ensure it is evenly wound to prevent tangling during operation.

Engage the Bump Feed System: For strimmers with a bump feed system, gently tap the strimmer head on the ground to release more line. This step may require a few taps until the desired line length is achieved.

Trim the Strimmer Wire: Once the replacement wire is in place, trim it to the appropriate length using a sharp pair of scissors. Avoid cutting it too short, as it may affect cutting performance.

Inspect and Secure: Double-check all the connections and make sure the replacement wire is securely fixed in the strimmer head. Properly reassemble any components that were removed during the process.

Reconnect the Strimmer: Once you are confident that the replacement wire is correctly installed, reconnect the strimmer to the power source.

Test the Strimmer: Turn on the cordless strimmer and test it in a controlled area to ensure that the new strimmer wire is working correctly and cutting effectively.

Adjusting the Cutting Height: If necessary, adjust the cutting height according to your specific lawn or gardening requirements. Refer to your strimmer’s user manual for guidance on adjusting the cutting height.

Maintain and Store the Strimmer Wire: Regularly inspect the strimmer wire for signs of wear and tear, and replace it whenever needed. Properly store the replacement wire in a dry and cool place to maintain its quality.
