I’m going to show you how to sharpen your hedge trimmer correctly. This is a simple process that should only take about 15 minutes of your time and will make all the difference in performance and safety.
When do You Need to Sharpen Trimmer?
Sometimes, the blades on your hedge trimmer get blunt over time. It’s not uncommon for this to happen because of their frequent use of hedge trimmers which causes them to become less keen and sharp than they used to be, especially in cold weather when you need it most. To fix these problems before things go too far, here are some symptoms that will help diagnose what may have caused them:
- Blades getting stuck mid-stroke or not cutting consistently could mean there’s something caught between its teeth (feel free to remove any obstacles). If this isn’t causing an issue but just makes noises while working then try cleaning out trapped dirt with compressed air. Otherwise, move on to step two.
- If you find that your hedge trimmer’s blades are getting stuck between their teeth, it may be time for some sharpening. The upper and lower blade meet but don’t cut because they have worn-out spacers holding them together. A typical sign of heavy use or abuse of power tools in general-your dealer can fix this problem by installing new ones.
- It’s important to keep your hedge trimmer blades sharp. If the blade leaves behind an uneven and frayed edge as it cuts, this can lead not only to an unpleasant appearance for your lawn but also damage done by weeds that will grow unchecked in those areas of trimming without teeth on their edges.
Tools Required to Sharpen Your Hedge Trimmer
- Whetstone
- Soft cloth
- Water
- STIHL resin solvent
- Safety clothing
- Work gloves
- Safety glasses or face protection
- Flat file
Instructions
It is important to sharpen your hedge trimmer before the blades show visible signs of wear. This will ensure that you can cut for a long time with it, even when cutting thick branches and bushes. You should also follow this routine after every 50 hours or so to avoid any inconsistent performance from one trimming session due to dulling over time – which means more laborious work on your part too.
The best way I’ve found sharpening them was by using an Arkansas stone whetstone alongside some fine-grit sandpaper wrapped around another type of guide rod called “frame”. It takes about thirty seconds per blade edge.
Clean the Teeth
Before you start sharpening the corded hedge trimmers, clean off any sap and resin that has accumulated on them. This will avoid polluting your air with heavy pollution from these toxins as well.
Sharpen the trimmer blades with the Flat File
There is a quick way to sharpen your hedge trimmer by hand and it only requires a few simple steps. You will first need the flat file, which works best for this task in my experience because of its precision teeth pattern designed specifically for getting rid of burrs left behind after sharpening.

When you move in downward motions, before going back uplift the file off of each time and only go down on one side (the guide should be facing upwards). If this process isn’t done patiently enough or quickly enough then filing will make it duller than when first bought; if grinding-out takes place too often little pieces get ground away at its edges until they become thin.
Remove Burrs from the Trimmer
Make sure you have a whetstone to sharpen the blades, take one side at a time and use light pressure while moving in an arc. Draw through each blade until it’s sharp enough for your liking – usually about 20 minutes per edge if done slowly but will vary depending on how much material there is being cut by different tools.

Sharpen Hedge Trimmer with Dremel
A Dremel tool is a small, handheld power tool that has special bits for refining blades. It’s similar in shape and size to an electric grinder but without a large number of spinning disks; instead, it uses smaller tools like chisels or grinders with more precision than your typical disc-style cutter (which can get kind of messy).
Make sure there are no grass clumps stuck on any blades! Then attach all screws/nuts provided from the kit so you know they’re tight before starting the sharpening process. Remember not to tighten down too much since these have the potential to be loose afterwords.
- Next, follow these steps to sharpen your hedge trimmer blades:
First, unlock and remove any shields from around the blade. - Next make sure you have a bench vise securely clamped onto the base of each tooth on both sides with enough force that it won’t move while sharpening takes place.
- Lock all parts tightly into place so they stay still during this process or else risk oversharpling one side more than another due to movement caused by improper clamping forces against an unsteady surface such as wood planks being used instead metal ones which will cause uneven pressure distribution resulting in different amounts applied per swipe across various areas depending if its lighter.
Sharpening Hedge Trimmer with Power Grinder
If you’re looking for a quick and easy way to sharpen the blades on your hedge clippers, then power-grinding might be just what you need. However, there is one thing that can go wrong: sparks. But don’t worry; this powerful approach only requires some know-how before getting down with business as usual (which means safety first!).
Here’s how it works… find the appropriate angle between 45 degrees – 70 degrees where most people usually grind their tools at medium speed without applying any pressure until they finish up by lightly touching or tapping over the area being ground away from myself if possible so the blade stays sharp longer overall). Remembering not too much pressure should also avoid overheating process.
It is important to use caution when sharpening the blades of an electric grinder. The bottom surface should be finished first, followed by each blade edge in short strokes for around 30 seconds on either side until you see enough shine coming from both sides.
Then repeat this process if needed or desired with less pressure applied while grinding away at your material so that there’s no overheating which causes over-grinding and breaking off too much metal – do not grind against itself unless absolute precision.
Maintenance After Sharpening
A little TLC will keep your hedge trimmer in good shape. First, remove any grinding dust generated during the filing process by vacuuming or blower cleaning followed by an application of resin solvent to ensure that you’re getting all specks off before sending it out for operation again.

What are the Safety Precautions for Sharpening Hedge Trimmer?
Before you begin sharpening, think about how best to protect yourself. Wear safety glasses and gloves made from robust material that will prevent injury when working with a tool in order not to have any accidents. It’s also a smart idea for beginners just starting so keep these tips top of mind before getting started on your project today.
Also, check the battery if you are using a cordless hedge trimmer.
Conclusion
To maintain your hedge trimmer, you should clean and sharpen the blades before every use. Before sharpening, you need to clean the blades with rubbing alcohol and remove burrs using a whetstone. Apply resin solvent if necessary for corrosion protection (or restore it). This will ensure that your hedge trimmer is sharpening correctly.
