Resin and thick branches will eventually blunt the cutting blades on your hedge trimmer over time. However, keeping them sharp is a simple process, and will etend the longevity of your blades, leaving you with a clean cut every time. Before we explain how to sharpen your blades, it’s important to understand how to tell when they are blunt.

How to tell if your blades need sharpening

Do you feel your hedge trimmer isn’t leaving you with a nice, clean cut anymore? This is not uncommon. Frequent use blunts the cutting blades, so they need sharpening regularly. If your petrol, battery or electric hedge trimmer leaves behind an uneven and frayed edge as it cuts, this indicates that it’s due for a sharpen. You can go to one of our dealers for a professional sharpen, or alternatively you can get the tool back into peak condition by yourself.

Ideally, sharpening should be done before the blades show visible signs of wear – remember that the lifespan of your hedge trimmer is heavily dependent on regular maintenance. As such, we recommend sharpening after every 50 hours of use or so, to ensure consistent cutting performance and to enable you to enjoy your hedge trimmer for as long as possible.

Watch to see how you can do this quickly and easily at home.

It is possible, however, that the problem arises from a different issue. If you are noticing a tendency for branches to get stuck between the teeth during trimming, so they block the tool without being cut, this suggests that the upper and lower blades of the hedge trimmer are no longer meeting. It happens because the spacers between the blades wear out over time. Your STIHL dealer can easily fix this issue by replacing the spacers for you.

If you’re not comfortable sharpening your hedge trimmer blades at home, your local STIHL dealer will be pleased to help, and can professionally sharpen the blades to achieve an optimal result without removing too much material.
