Sharpening the Blade
Before you start sharpening the blade, it is important to ensure your safety. Wear protective gloves and safety glasses to avoid any accidents or injuries. Make sure the chain brake is engaged and the chainsaw is turned off before proceeding.
1. Position the chainsaw securely on a flat and stable surface.
2. Use a 3/16-inch round file to sharpen the Stihl chisel blade. This file size is recommended by Stihl for optimal sharpening results.
3. Start by locating the cutting edge of the blade. This is usually indicated by a small arrow or a mark on the top plate of the blade.
4. Hold the file securely and place it on the cutting edge, matching the angle of the blade. Use a filing guide if needed to maintain the correct angle.
5. Push the file in a forward motion along the cutting edge. Apply firm and even pressure, while maintaining the angle of the blade. Repeat this motion for 2-3 strokes.
6. Lift the file off the blade and reposition it on the next cutting edge. Repeat the filing motion for the remaining cutting edges of the blade.
7. Once all the cutting edges are sharpened, use a flat file to remove any burrs or rough edges from the top plate of the blade. This will help ensure a smooth and clean cutting action.
8. Check the depth gauges of the blade. These are the small metal protrusions in front of each cutting edge. Use a depth gauge guide or a special depth gauge file to set the correct height for the depth gauges.
9. Finally, lubricate the blade with a high-quality chainsaw oil before reassembling and using it.
Note: It is important to regularly inspect and sharpen your Stihl chisel blade to ensure optimal performance and safety. If the blade is excessively worn or damaged, it may need to be replaced.
Choosing the Right File
When it comes to sharpening a Stihl chisel blade, choosing the right file is crucial. The file you select should match the pitch and gauge of your specific blade.
Pitch
The pitch of a chainsaw chain refers to the distance between three consecutive cutting teeth. There are three common pitches for Stihl chisel chains: .325-inch, 3/8-inch, and .404-inch. Each pitch requires a file with a specific diameter. Make sure to check your chain specifications and select a file that matches the pitch.
Gauge
The gauge of a chainsaw chain refers to the thickness of the drive links. Stihl chisel chains typically come in three gauges: .050-inch, .058-inch, and .063-inch. The file you choose should have a diameter that matches the gauge of your blade. Using a file with the wrong diameter can result in an uneven sharpening job.
It’s important to note that Stihl offers different file sizes for various chain pitches and gauges. Make sure to consult the Stihl owner’s manual or contact a professional dealer to determine the correct file size for your specific blade model.
Investing in the right file will ensure a precise and effective sharpening of your Stihl chisel blade, leading to improved cutting performance and prolonged blade life.
Sharpening Technique
Properly sharpening your Stihl chisel blade is essential for maintaining its cutting performance. Follow these steps to sharpen your blade using the correct technique:
Step 1: Preparation
Start by wearing the necessary safety gear, including gloves and eye protection, to protect yourself from any possible debris or accidents. Ensure that the saw is turned off and the chain brake is engaged before beginning any maintenance work.
Step 2: Positioning the Blade
Secure the saw in a vice or use a bar clamp to hold the saw in place. Make sure the blade is properly positioned and facing towards you for easy access.
Step 3: Filing the Blade
Using a round file and file guide, begin sharpening the blade by inserting the file into the first tooth of the chain. Apply light pressure and push the file across the tooth using smooth, even strokes away from you. Repeat this process for each tooth, ensuring equal pressure and number of strokes for consistent sharpening.
Step 4: Checking Depth Gauge
After sharpening the blade, it’s important to check the depth gauges. These are the small protrusions in front of each tooth.

Once you have filed all the teeth and adjusted the depth gauges, continue the filing process in the opposite direction using the file guide. This helps remove any burrs or rough edges left from the initial filing process, resulting in a sharper and more precise blade.
Step 6: Lubrication
Before reassembling the chain, it is important to lubricate it with chainsaw oil. This helps reduce friction and heat during operation, improving the overall performance and lifespan of the blade.
Following these steps and maintaining a regular sharpening schedule will ensure that your Stihl chisel blade remains sharp, efficient, and safe to use.
Testing and Reinstalling the Blade
Once you have finished sharpening your Stihl chisel blade, it’s important to test its effectiveness before reinstalling it on your chainsaw. This ensures that you have achieved the desired sharpness and the blade is ready for use.
First, carefully inspect the blade for any signs of damage or excessive wear. Check for any cracks, chips, or missing teeth. If you notice any of these issues, it’s recommended to replace the blade with a new one.
Next, hold the blade up to the light and look for any reflection on the cutting edge. A sharp blade should have a clean, straight cutting edge without any light reflecting. If you see any light reflection, it indicates that the blade still requires sharpening.
To test the blade’s sharpness further, take a piece of scrap wood and make a small cut. A properly sharpened blade should effortlessly cut through the wood with minimal force. If you encounter resistance or the blade struggles to cut through, it means that the blade needs additional sharpening.
Finally, once you are satisfied with the sharpness of your Stihl chisel blade, carefully reinstall it onto your chainsaw according to the manufacturer’s instructions. Make sure to tighten the bolts securely to ensure the blade is properly positioned and will not come loose during use.
Remember to always wear appropriate safety gear, such as safety glasses and gloves, when handling and testing the blade.
