Your hedge trimmer is an important tool in your arsenal for keeping your hedges trimmed and tidy. But like any tool, it will eventually become dull and will need to be sharpened. In this guide, we’ll show you how to sharpen your hedge trimmer quickly and easily, so you can get back to work.

Tools and Materials Needed:
-Hedge trimmer
-Wrench (if needed)
-protective gloves

Step 1: Inspect Your Hedge Trimmer
Before you begin sharpening your hedge trimmer, it’s important to inspect it for any damage. Look for cracks, chips or damage on the blades. If you find any damage, stop sharpening and replace the damaged parts before continuing.

Step 2: loosen the Blade Guard
Once you’ve inspected your hedge trimmer and found no damage, you’re ready to begin sharpening. First, you’ll need to loosen the blade guard. This is typically done with a wrench. Check your manual for specific instructions on how to do this.

Step 3: Sharpen One Side of the Blade at a Time
Once the blade guard is loose, you can begin sharpening the blades. It’s important to only sharpen one side of the blade at a time. This prevents the blade from becoming unbalanced and helps ensure a clean, even cut. Use a file or other sharpening tool to slowly work your way along one side of the blade. Be sure to follow the angle of the existing edge as you sharpen. You should feel a burr forming on the opposite side of the blade as you sharpen. Once you’ve gone all the way around the blade, flip it over and repeat on the other side. If you’re having trouble getting a burr to form, try honing the blade with a honing stone before trying again.

What You’ll Need

Before you begin sharpening your hedge trimmer, you’ll need to gather a few supplies. You’ll need a file, a cloth, and some oil. You may also want to wear gloves to protect your hands from the sharp blades.

Once you have your supplies, follow these steps to sharpen your hedge trimmer:

1. Unplug the hedge trimmer and lay it on a flat surface.
2. Inspect the blades for damage. If there are any cracks or chips in the blades, replace them before continuing.
3. using a file, Sharpen the blades by running the file along the edge of the blade in one direction.
4. After you’ve finished sharpening both blades, wipe them down with a cloth to remove any filings.
5. Plug in the hedge trimmer and test it on a piece of paper to make sure it’s sharp enough for your needs.

Step One: Remove the Battery

Most modern hedge trimmers have a battery that needs to be removed before beginning the sharpening process. Unscrew the cover on the battery compartment and gently lift the battery out. If your model has a cord, unplug it from the outlet.

Step Two: Inspect the Blades
Now that the power source has been removed, you can inspect the blades more closely. Check for nicks, chips, or other damage that may have occurred during use. If there is any damage, use a file to smooth it out before proceeding to the next step.

Step Three: Sharpen the Blades
There are two ways to sharpen your hedge trimmer blades: with a sharpening stone or with a rotary tool. If you opt for a Sharpening stone, wet it first and then hold the blade at a 10-15 degree angle against the stone. Use light pressure and move from left to right until you’ve sharpened the entire blade. If you’re using a rotary tool, fit it with a grinding wheel and follow the same process.

Step Four: Reassemble and Test
Once you’ve finished sharpening the blades, reassemble your hedge trimmer and test it on a piece of paper or cardboard. If the blades are still not cutting as smoothly as you’d like, repeat steps three and four until they are satisfactory.

Step Two: Inspect the Blades

With the hedge trimmer unplugged, inspect the blades for damage. If there are any nicks or cracks, you will need to replace the blade. Most hardware stores or home improvement stores will sell replacement hedge trimmer blades.

If the blades are only dull, you can sharpen them with a file. Be sure to use a file that is rated for use with metal. You can find these files at most hardware stores or home improvement stores.

Step Three: Sharpen the Blades

With the guide block in place, take your file and hold it at a 90-degree angle to the blade. Starting at the base of the blade, use long, even strokes to sharpen the blade. Remember to stroke in the same direction as the blade is sharpened. Use light pressure at first and then increase pressure as needed. Be sure to evenly sharpen both sides of the blade.

Step Four: Replace the Battery

If your hedge trimmer is electric, open the cover on the top of the unit to access the battery. Remove the battery and insert a new one, being careful to line up the positive and negative posts correctly. Close the cover and screw it in place.
