A chainsaw is a portable power saw, which has a rotating chain that runs along a guide bar. A set of teeth is attached to the rotating teeth, which I used to cut and doing activities like tree limbing, felling, pruning, cutting firebreaks and harvesting firewood.

A chainsaw can be sharpened using a hand, or using a sharpening machine or by using the above tools. In this section, we will tell you how to use a chainsaw sharpener and also how to sharpen a chainsaw with your hand.
Step 1- Sharpening a chain saw with hand
- First of all find the size of the chainsaw link, which is also called pitch.
- Use the pitch number for getting match file with correct diameter.
- Use less aggressive cleaners to avoid damaging the saw while cleaning the chain thoroughly to get rid of dust and dirt or oils
- Find the damaged, cracked or bent cutting links and replaced them with new ones. Damaged cutting links can be dangerous and can cause accidents
- Fasten the chainsaw and its bar to make it static while filing and position the bar in such a that it allows the chain to move freely
- Hold the handle of file with one hand and use another hand to guide the motion of the file. Keep in mind that the file only sharpens on the forward motion. Filing in the backward motion may make the file dull
- Rotate the file while filing so that it wears out evenly
- Check after filing to make sure if the cutting link is filed evenly or not
Step -2 Sharpening with power tools

- Ensure the protection first like; wear goggles, glove, etc.
- Engaging the chain brake, lightly clamp the bar of the chainsaw in a bench vise. Then release the chain brake so that the chain can be able to rotate by hand
- Place the file guide over the cutter, if using one with the file in the gullet, which is between the cutter and the depth gauge. Make sure the file guide has on point of contact on the top plate of cutter and another on the depth gauge
- Hold the file’s diameter 20% above the cutter’s top plate, so that the file is in the correct position
- Make sure the top plate filing angle is parallel to chainsaw chain centerline.
- Sharpen using even strokes in the most damaged area of the cutter to remove damage. When the cutter is shiny and silver it means that the damage is removed
- Before switching to another side of the change, complete all the cutters on one side.
- File again to keep the length of top plates equal and to remove damage
- Recheck the depth gauges.
Safety measures of sharpening a chainsaw
