If you own a Stihl hedge trimmer, you know that it is an important tool to have in order to keep your hedges looking their best. However, over time, the blades on your trimmer can become dull, making it more difficult to use. In this article, we will show you how to sharpen your Stihl hedge trimmer blades so that you can keep your hedges looking neat and tidy.

What You’ll Need

To sharpen your Stihl hedge trimmer, you’ll need a few supplies. First, you’ll need a sharpening stone. You can use either a natural stone or a man-made one, but it’s important to make sure that the stone is rated for use with carbide blades. You’ll also need some lightweight oil, like mineral oil or WD-40.

Next, you’ll need to gather some safety equipment. Make sure you have a pair of gloves to protect your hands, and eye protection to guard against flying chips of stone. You might also want to consider using a dust mask to avoid inhaling any particles generated by the sharpening process.

Once you have your supplies gathered, you’re ready to begin sharpening your Stihl hedge trimmer.

Preparing the Hedge Trimmer

To sharpen your Stihl hedge trimmer, you will need the following items:
-A sharpening stone
-A file
-Protective gloves
-Eye protection

First, put on your gloves and eye protection. Next, locate the two screws that hold the hand guard in place. Loosen these screws and remove the hand guard. Be careful not to lose the screws, as they are easy to misplace. With the hand guard removed, you will have better access to the blade.

Sharpening the Blades

Over time, the blades on your Stihl hedge trimmer will become dull, and this can make it difficult to get a clean, precise cut. Fortunately, sharpening the blades is a fairly simple process that you can do at home with just a few tools. You’ll need a file and a pair of gloves.

First, put on your gloves to protect your hands from the sharp blades. Then, locate the file holder on the side of the blade. This is a small, metal piece that holds the file in place. Insert the file into the holder and align it with the angle of the blade.

Next, start moving the file back and forth across the blade. Be sure to apply pressure evenly so that you don’t create any uneven spots. Continue until both sides of the blade are evenly sharpened.

Once you’re finished, remove the file and put it away. Then, test out your newly sharpened blades on a piece of paper or cardboard to make sure they’re cutting properly.

Maintaining Your Hedge Trimmer

Your Stihl hedge trimmer is a precision tool that, with proper care and maintenance, will provide you with years of trouble-free service. Part of this care involves routine sharpening of the cutting blades. While you could take your trimmer to a professional for this task, it’s actually quite easy to do at home with just a few basic tools.


Following these steps will ensure that your Stihl hedge trimmer stays sharp and operates at its best. By keeping the blades sharp, you’ll not only improve the efficiency of your trimmer, but you’ll also reduce the risk of injury.
