The Ultimate Guide to Strimmer Cord: Choosing, Using, and Troubleshooting

Introduction

A strimmer, also known as a weed eater or line trimmer, is a handheld power tool used to trim grass and weeds in gardens, parks, and other outdoor areas. The cutting mechanism of a strimmer consists of a rapidly spinning nylon cord, known as strimmer cord. The choice of the right strimmer cord can significantly impact the efficiency and effectiveness of your trimming task. This comprehensive guide will provide you with all the information you need to select, use, and troubleshoot strimmer cord to achieve optimal results.

Choosing the Right Strimmer Cord

The type of strimmer cord you choose will depend on the following factors:

• Trimmer Model: Different strimmers require different types of cord, based on the size of the trimmer head and the power of the motor.
• Application: Consider the type of vegetation you will be trimming. Thicker cords are suitable for heavier weeds, while thinner cords are more appropriate for delicate plants.
• Cord Shape: Cords can be round, square, or star-shaped. Round cords are the most common and are suitable for most applications.

Types of Strimmer Cord

There are several types of strimmer cord available, including:

• Nylon: The most common type of strimmer cord, nylon is durable and flexible, making it suitable for a wide range of applications.
• Polyethylene: More durable than nylon, polyethylene cord is ideal for heavy-duty trimming.
• Co-Polymer: A blend of nylon and polyethylene, co-polymer cord offers a balance of durability and flexibility.
• Twisted: Twisted cords are made from multiple strands of nylon or polyethylene, resulting in increased strength and durability.
• Square: Square cords cut more efficiently through thick weeds and have a longer lifespan than round cords.
• Star: Star-shaped cords are designed for precision cutting and are suitable for delicate plants.

Cord Diameter and Length

The diameter of the cord you choose will depend on the power of your strimmer. A general rule of thumb is:

• Small trimmers (up to 1200W): 1.6mm - 2.4mm
• Medium trimmers (1200W - 1800W): 2.4mm - 3.0mm
• Large trimmers (over 1800W): 3.0mm - 3.3mm

The length of the cord depends on the size of your strimmer head. Most strimmer heads hold between 5m and 15m of cord.

Using Strimmer Cord

Step 1: Install the Cord

Refer to the manufacturer's instructions for detailed steps on installing the strimmer cord. Generally, it involves feeding the cord through the eyelet of the spool and winding it around the spool until it reaches the desired length.

Step 2: Adjust the Cord Length

After installing the cord, adjust the length by tapping the trimmer head on the ground. The cord should extend approximately 10-15cm beyond the edge of the trimmer head.

Step 3: Start Trimming

Hold the trimmer firmly and start trimming the vegetation by moving the trimmer head in a sweeping motion. Avoid pressing the trimmer head into the ground, as this can damage the cord.

Step 4: Replace the Cord

When the cord becomes too short or damaged, it is time to replace it. Follow the manufacturer's instructions for removing the old cord and installing a new one.

Troubleshooting Strimmer Cord

Common Problems:

• Cord Breaking Frequently: This can be caused by using the wrong type of cord for your trimmer, winding the cord too tightly, or hitting hard objects with the trimmer head.
• Cord Not Feeding Properly: Check if the cord is jammed in the spool or if the spool is damaged.
• Cord Curling: This can be caused by winding the cord in the wrong direction or using a twisted cord that is not designed for your trimmer.

Tips for Troubleshooting:

• Use the correct type and diameter of cord for your trimmer.
• Wind the cord evenly and avoid winding it too tightly.
• Inspect the spool regularly for damage and replace it if necessary.
• Use unwound cord or untwist the cord before winding it onto the spool.
