How to Change a Chain on a Sears Chain Saw

When the chain on a Sears chain saw hits anything other than wood it will dull, get damaged or broken. This can occur over only a few uses, but if properly cared for, a chain will last a long time. However, without a sharp, properly working chain, the operator will need to work harder to cut through wood, which also makes his work more dangerous. To prevent injury and cut efficiently, the operator will need to regularly take the chain off and exchange it for a new and sharp chain.
