Five Easy Steps to Sharpen Stihl Hedge Trimmer Blades
Here are the steps you need to follow to sharpen your hedge trimmer blades
Step 1: Clean the Blades of Your Hedge Trimmer
Before sharpening with a flat file, you should clean the teeth of your Stihl hedge trimmer. During regular use, the resins and sap usually accumulate on the blades and reduce their sharpness.
Cleaning the blades with a wet cloth or simply washing and wiping them will help them sharpen more effectively. You can also clean the blades of your Stihl hedge trimmer with soap and water if they are too dirty. But remember to dry the blades before jumping to the next step.
Step 2: Align the Upper and Lower Blades of your Hedge Trimmer
Branches stuck in the blades of your hedge trimmer during use affect their alignment. To align them properly, place your Stihl hedge trimmer on a flat surface and gently press the upper and lower blades to bring them closer.
If your hedge trimmer’s blades need to be more aligned, take it to a dealer, who will align them according to the model and manufacturing of your trimmer.
Step 3: Use a Flat File to Sharpen Hedge Trimmer Blades
Follow these easy steps to use a flat-file properly to sharpen Stihl hedge trimmer blades:
- Flat files are designed in a particular way. They only work effectively when used in one direction. If this is your first time using a flat file, consider learning how to use it for better results.
- To use a flat-file according to its specific angle, always read the instructions on the package.
- Use a flat file in the direction of the cutting edges of your hedge trimmer’s blades to make them sharper.
- Avoid sawing the surface of your blades with your file in a back-and-forth motion, as this can cause your blades to become blunt again.
- Usually, a flat file is most effective in forwarding strokes. So lift your flat file from the surface when your move your hand backward.
- Only file a little! The abrasion limit of your file should be at most 5mm. If you continue to use the file beyond the recommended limit, you risk damaging your blades and rendering your hedge trimmer useless.
- Remember how many strokes you used on each blade and apply the same number to all others to give them the same sharp length and shape.
- You should only use the flat file on the cutting edges of the blades on your hedge trimmer. Refrain from applying strokes on the integrated parts of your Stihl hedge trimmer.
Step 4: Use Whetstone for a Smooth Finish
Use a whetstone to smooth out the finish on your hedge trimmer and eliminate any burrs that formed from filing. Turn over the hedge trimmer to have a clear view of the other side of the blades. Now carefully draw a whetstone in slow motion on each blade in the direction of the edge. Smooth the rough surface of the blades and give them a sharp finish.
Wearing safety gloves during this process is mandatory to avoid injuring your hands with sharp blades.
Step 5: Post Care after Sharpening of Blades
Well done! You have almost finished the job. Your freshly sharpened Stihl hedge trimmer needs a little post-care in this step.
Remove any grinding dust that has accumulated during the filing process. It is understood that the filing process removed the corrosion protection from your hedge trimmer’s blades.
