For this reason, you should pressurize to cut with it. You can sharpen the chainsaw to restore its previous condition using the right tools and methods. In whatever way, I am here to provide information about the excellent tricks to sharpen a chainsaw. You’re going to get all the information you need to do it.
Keep reading to know more. So, let’s get started.
How To Sharpen Any Chainsaw: A Step-by-step Guide
Sharpening a chainsaw with a file guide is a manual task. It’s somewhat different than using a filing machine. A file guide can reach the exact angle of the blades and sharpen the blade too deep. The marking on the file guide shows the guide angle when you’re sharpening. Certainly, it’s a very easy process.
Generally, you can apply this guide to all chainsaws. However, you should read the chainsaw user manual for any recommendations from the manufacturer.
Things You’ll Need
- A round file- to sharpen the curved hollow part of the cutting link
- A filing guide- to get the right chainsaw sharpening angles when using the round file and to determine the proper cutting depth to which you’ll file the cutting link
- Safety equipment (Hand-gloves, goggles)
- Cleaner and rag
Chainsaw Sharpening Process
For your easy understanding, we’ve divided this guideline into three PARTS.
Part 1: Pre-steps
Step 1: Find The Size Of The Pitch Or Chainsaw Link
Different chainsaws come with different size pitches or teeth. In general, there is code (depth gauge marking) etched on the side of the pitch. You can find its size on the outer side of the depth gauge.
Step 2: Buy The Correct Sized File
Different chainsaws will need different-sized files to sharpen. Using the incorrect-sized file will damage your file and of course your chainsaw. So, buy the round file that matches the diameter of the chainsaw’s teeth.
From this conversion table, get the matching rounded file. Try to buy the files from the tool shops or suppliers recommended by manufacturers.

|Depth Gauge Marking||Alternative Depth Gauge marking||Chain Pitch||Round File|
|6||P, PM||3/8” Picco||4.0mm|
Step 3: Thoroughly Clean Your Chain
Remove the dirt, debris, and sawdust from the chain. For removing oil, you can use less aggressive detergents and mineral spirits.
Step 4: Check To Find Out The Damaged Cutting Link
If you find any excessively damaged, bent, or chipped pitch, you should replace it with new ones. Also, measure the upper plate of the pitch. Note that, it should be a minimum of ¼” long. If you find it shorter, replace it.
Part 2: Setting The File
Step 1: Clamp The Chainsaw And Bar To The Work Surface
Use a vise or tabletop clamp to keep the bar and chainsaw in the most stable position so that it won’t move when filling. Position the bar in the vise such that the bar can spin freely. Isn’t the clamp Available? No worry!
Remove the chain from the chainsaw bar and secure it in the vise. Though you may need to make a few more adjustments, it’s an easy alternative. If a clamp or vise isn’t available, you can go without it. Just be careful enough to hold the chainsaw steadily when you file it.
Step 2: Tighten The Chain
Tightening the chain in advance will make it easier to sharpen each tooth. It’ll also help the chain to stop moving as you sharpen the teeth. Tighten the tension adjusting screw on your chainsaw by using a screwdriver. Don’t tighten too much. Make sure that you can move around the chain with a little effort.
Step 3: Put A Mark On The First Tooth You’re Going To Start Sharpening
It’s a good idea to mark the first tooth that you start sharpening. It’ll help you to keep track of your starting point and know where to stop. You can use a bright permanent marker to mark the starting tooth. If you don’t like to mark the chainsaw or no marker is available, look for a unique link in the chain.
Step 4: Set The Round File In The Curve On The Front Of The Flat Surface Of The Chain Link
Place the tip of the round file inside the curve on the marked tooth. To maintain the correct shape of the cutting surface, make sure that you hold approximately 20% of the height of the file above the top of the cutting tooth.
Step 5: Use A File Holder To Hold Your File At The Same Angle The Cutter Was Initially Ground
If you use a file guide for sharpening, to find the correct angle for each tooth, check your chainsaw’s manual or look online. Keep the file in line with the file holder across the bar at an angle needed for your saw and keep the file very very level too.
Part 3: Sharpening The Cutters
Step 1: Move The File Smoothly Across The Face Of The Cutter
Slide the file through the cutter so that you feel the file grinding against the cutter. You should slide the file only on the forward motion. Don’t move the file in a backward motion through the cutter while sharpening.
To restore a sharp edge to a tooth that has been lightly worn, two or three strokes should be enough.
- More strokes may be required if the tooth is heavily worn.
- Count and remember how many strokes you have applied to sharpen the first tooth so that you can do the process consistently.
- Generally, the chain features two types of cutter that are facing alternate directions. First, focus on one type of cutter, before sharpening the other type.
Step 2: File Every Second Tooth From The Marked Tooth
Once you’ve filed one type of tooth, spin the chain to bring the second tooth closer. File every other cutter at the same angle, using the same motion. Use the same number of strokes to file the second tooth. You should stay consistent while filing across all the chainsaw cutters.
Step 3: Turn The Chainsaw At a 180-Degree Angle
When you are done sharpening one side, to sharpen the teeth for the other side that you’ve skipped sharpening at the first loop around the chain, turn the chainsaw 180-degree and follow the same process.
Step 4: File Each Tooth That Has Not Been Sharpened Yet
Sharpen each other teeth using the same motion and stroke to keep every cutter level consistent.
Step 5: Loosen The Chain
Loosen the chain and back to a proper tension by using the adjustment screws. Also, loosen the vise or clamp and take your chainsaw out. That makes a nice job and your chainsaw is now ready to use. Instead of using a file to sharpen a chainsaw, you can use a circular electric chainsaw sharpener.

Keep an eye on how many times you are rubbing the sharpening machine when it is sharpening. If each tooth is rubbed in equal numbers, there is no possibility of uneven sharpening. That would be a great solution.
Another thing is needing to sharpen the blunt teeth first. You will be tired when you sharpen the low teeth. This will reduce the amount of sharpening of the lower teeth. As a result, all the teeth will be sharpened evenly.
3. Applying The Imprecise File Size:
It’s a big deal that you can use the perfect size file on the chain saw. Different sizes of chain saw teeth of various sizes. Teeth get smaller and bigger according to the size of the chainsaw.
The files are also of the prescribed size for sharpening work. You need to match the right size file with the right size chain. You need to use the right size file to avoid this kind of problem. That’s why applying the imprecise file size is a great mistake.
4. Using A Tedious File:
As a result of using each file of Chain Sou, it gradually fades away. You have to be fully aware of the possession of the file. Lack of caution towards the file can cause it to become dull. That’s why using a tedious file is a great mistake in this case.

- You should check your chainsaw owner’s manual before deciding on sharpening the unit.
What Is The Best Way To Sharpen A Chainsaw?
The best way is to clean and set the chainsaw file first while sharpening it. For this, set it with a clamp bar to its work area. Then, tight the chain with a tensioning adjusting screw. Now, mark the teeth to start sharpening and also try to mark the round file. Now, slide the file frequently.
You can try to file the cutter 5 to 15 times. Remember how many times after trying it is getting sharper. Slide each tooth evenly so that it is not sharp or too sharp. Thus the main sharpening work will end. Now, set the miter gauge on the chainsaw and check the depth.
