If you are having trouble with chipped weed eater blades, there are a couple of things that you can do to repair this. Here is a step by step guide to help you through the process with ease.

Step 1 - Assess the Situation

The first thing that you will need to do is decide how serious the chip and the overall damage is to the blade. If you are dealing with a very small chip on the edge of the blade and you feel as though you can repair it by sharpening and smoothing the edge you can move to step 2. However if it looks like you need to do a complete replacement of the blade because the chip is too big or far up on the blade then you can jump to step 3. Before beginning either one of these steps you will want to turn the power off to the weed eater completely.

Step 2 - Sharpen the Blade

By sharpening the end of the blade you may be able to get that chip out and smooth out everything overall. You will need to first take the blade out. You can do this by using a wrench to loosen the nut that is on the edge of the blade. Once it is loosened you can remove any nuts and washers that may be connected to the blade still and clean them with a damp rag. Use a sharpening file or grinder to follow the contour of the blade. Continue to sharpen until it has become smooth and sharp on the edges. Make sure that everything is level as you go along. If this does not seem to get the chip out then you will want to just replace the blade.

Step 3 - Replace the Blade

You will need to make sure that the blade has been removed if you have not already tried doing this to sharpen it. You can follow the beginning of step 2 to remove the nuts and bolts from the blade to take it off completely. Make sure that you find the make and model of your weed eater so that you know what kind of replacement blade you will need to get so it will fit properly. Then you can use the same method you did to take the blade apart to put it back together. Install the nuts and bolts with the washers and then use a wrench to make sure that everything is being secured tightly and is not wobbling. You may want to use pliers to be sure that everything has been secured. Take your time on this part as you need to make sure that you are completely securing the blade.

These steps will help you through the process and you should be able to restore the power to your weed eater and test it to make sure the repaired or replaced blade is working.
