The Importance of Proper Blade Maintenance for Your Stihl Weed Eater

It may seem like a small component of your Stihl weed eater, but the plastic blades play a crucial role in its overall performance. These blades are responsible for cutting through tough weeds and grass, ensuring that your yard or garden is well-manicured. Without proper maintenance, these blades can become dull, damaged, or even break altogether. This not only affects the effectiveness of your weed eater but can also lead to potential safety hazards.

One of the key ways to ensure that your Stihl weed eater is functioning at its maximum capability is by regularly changing the plastic blades. Regular maintenance will not only prolong the life of your machine but also save you time and money in the long run. In this guide, we will walk you through step by step on how to change the plastic blades on your Stihl weed eater.

Gather All Necessary Tools and Equipment

Before we dive into the actual process of changing the plastic blades, it’s important to gather all the necessary tools and equipment first. You will need safety goggles, gloves, a flathead screwdriver, scissors or shears, and new replacement blades designed specifically for your Stihl weed eater model.

It’s important to note that using generic or incorrect replacement blades can negatively affect the performance of your machine or even cause damage. It’s always best to stick with genuine replacement parts recommended by Stihl for optimal results.

Prepare Your Weed Eater for Maintenance

The first step in changing plastic blades on your Stihl weed eater is to prepare it for maintenance. We recommend wearing protective gear such as gloves and goggles while working with any machinery. Next, securely hold down the head of the weed eater and remove it from its power source.

Use a clean cloth or towel to wipe down any excess dirt or debris from the blade area. This will ensure that no foreign objects get caught or stuck during the maintenance process.

Remove the Old Blades

With your flathead screwdriver, locate the two screws on either side of the weed eater head. These screws hold the plastic blades in place. Using your screwdriver, gently loosen and remove these screws.

With the screws removed, carefully take out the old blades from their designated slots. It’s always a good idea to inspect the old blades for any cracks, nicks or damage. If there is noticeable damage, it’s best to replace all blades rather than just one.

Replace with New Blades

Now that you’ve removed the old blades, it’s time to replace them with new ones. Take out your new replacement blades and align them in their designated slots on either side of the weed eater head.

Using your screwdriver, reattach and tighten the screws on both sides of the weed eater head to secure the new blades in place. Make sure that they are secured tightly but not overly tightened as this can cause damage.

Cut off Excess Blade Length

After replacing your plastic blades, you may notice that they are a bit longer than necessary. Use scissors or shears to carefully trim off any excess length from each blade. This will ensure that each blade is uniform in size and able to perform efficiently.

Test Your Weed Eater

Now that you’ve successfully changed your plastic blades, it’s time to test out your Stihl weed eater. Reattach it to its power source and turn it on to ensure that everything is working properly. Take it for a test run in an area with tall weeds or grass to see how well it cuts.

If you notice any issues with performance or notice that one blade is not cutting properly, double-check to make sure it’s securely attached. If the problem persists, it may be necessary to replace all blades again.
