Sharpening Your Hedge Trimmer Yourself

It is a normal thing for the blades of hedge trimmers to lose their sharpness over time which is why you need to sharpen them every once in a while.

However, you’re not supposed to wait until the blades are completely dull before doing something about them.

Ideally, you should sharpen your hedge trimmer blades at least after you’ve used them for up to 50 hours.

One of the things that make sharpening hedge trimmer blades difficult is dried resin and sap which often become glued to the trimmer blades during pruning and after a while get dried on the blades.

Therefore, make it a habit to completely eradicate any sap or resin before you start filing. This will prevent your sharpening instruments from getting damaged.

A rule to keep in mind as you sharpen your blades is to sharpen only the cutting edge.

Try as much as possible to prevent your file from touching the cut protection. In a professional trimmer, this protection is usually orange in colour.

How to Sharpen Hedge Trimmer Blades?

Here are two recommended sharpening ways below you may utilize.

1. Sharpen with a File

The ideal file for this job is a flat file. Align the upper and lower blades such that they lay in a corresponding position. You need to do this to make the filing process easier for you.

Only file your trimmer in the same direction as your blades cutting edge. Endeavour to comply with the stipulated sharpening angle.

Check your instruction manual for the specifications. Keep the file out of contact with the blade as you pull the file upwards as this can cause the blade to become blunt. Only sharpen backwards.

It is important that you do not over file your blades. You mustn’t file away more than 5mm of the blade. Scraping off too much can weaken the blade.

Also, maintain a steady amount of pressure as you sharpen. Using varied force will result in uneven blade lengths at the end of the filing.

2. Remove All Burr

Now that your blades are all sharpened, it’s time to remove burr or swarf and you can do this using a sharpening stone.

Once you’re done doing this, it is important that you find a way to protect your blades from rust. You can use a resin-free spray for this.

Conclusion

The GreenMachinery says, though you have the best hedge trimmer, if you don’t maintain your tool, it’ll not give you best service.

While this task is easy to handle on your own, if you’d prefer not to, you can take your hedge trimmer blades to specialized retailers so they can sharpen them for you.

They have sharpening machines that they use for these tasks and because they’re professionals, they tend to do it well.

However, you do have to pay a small amount for their services.
