How to Restring a Stihl Weed Eater: A Step-by-Step Guide

Keeping your Stihl weed eater running smoothly requires routine maintenance, and restringing the trimmer head is a crucial part of that process. While it might seem daunting at first, restringing your Stihl weed eater is a quick and easy process that can be done in a matter of minutes with the right instructions. This guide will walk you through everything you need to know, from identifying your trimmer head type to successfully loading a new trimmer line.

Understanding Your Stihl Trimmer Head

Stihl offers a variety of trimmer heads, each with its restringing method. Here’s a breakdown of the two most common types:

• Fixed-line head:This is the simpler design, typically found on older Stihl models. It requires manually feeding the line through designated holes.
• Automatic bump-feed head: This more modern design features a spool that feeds a new line automatically when you tap the trimmer head on the ground.

Knowing your trimmer head type is essential before diving into the restringing process. Refer to your Stihl owner’s manual or search online for your specific model to identify the type of head you have.

Stihl Trimmer Line Replacement: Choosing the Right Line

Stihl recommends using high-quality trimmer lines specifically designed for their trimmers. This ensures optimal performance and reduces the risk of line breakage. Here are some factors to consider when choosing a trimmer line:

• Line diameter: Stihl trimmer heads are designed for specific line diameters, typically ranging from 2.0mm to 2.7mm. Using the wrong diameter can lead to feeding issues or damage to the trimmer head.
• Line shape: Round lines are the most common, but Stihl also offers square and star-shaped lines for different cutting applications. Round lines are good for general trimming, while square and star-shaped lines offer improved cutting performance for thicker brushes.
• Line length:Spools come in various lengths, but most homeowners won’t need a professional-grade bulk spool. Opt for a pre-cut spool or choose a bulk spool length that suits your needs.

Does Soaking Stihl Weed Eater String in Water Help?

While some users recommend soaking the trimmer line in water to soften it and reduce breakage, Stihl does not recommend this practice. Their high-quality trimmer line is already formulated for flexibility and performance. Soaking can weaken the line and make it more prone to breaking.
