How to Cut and Repair a Chainsaw Chain
In order to repair your chainsaw chain, you must first be able to disassemble your chainsaw and safely remove the chain itself. Once you have removed the chain, you can then examine all the links and figure out what it is causing the problem. Here is a simple and easy-to-understand breakdown of this process.

Using a socket wrench, remove the two nuts on the side of the chainsaw casing, near the handle, that attach the cover to the blade. Remove the cover of the casing once the nuts are removed. This will reveal the drive socket assembly, bar, and chain of the saw.

Notice the tension wheel located just inside the bar. Use a flat-head screwdriver to turn the screw to the left and release some tension. Pull the chain away from the grooves of the bar. Ensure that all of the grooves are removed all the way down the bar until the chain is free.

Work the chain loose from the drive sprocket once it is free from the bar by pulling it over the drive sprocket. The drive sprocket is the wheel located just under the handle. Once this task is completed, you should then be able to find any faulty links in your chain. These links may be broken, rusted, or bent and could cause a problem in the operation of your tool. If this is the case, you will need to remove the links that are causing the problem.

Examine your chain thoroughly and figure out whether there is a master link, which is a link that several brands of saws have that help safely remove other links. The master link will be noticeable because it will look slightly different or larger than the other links. If you do not notice a master link, then you will need to obtain a chain breaker or "punch" to remove links. Use this tool to punch out the rivets that hold the links together. Once you have removed any faulty links, you may then easily snap the other links together and begin reassembling your chainsaw.
