Finally, now that you know what to look for, there are a few things to keep in mind as you work with and diagnose your power tools. First, just like energy runs down the electrical path in your power tools, so does damage. Within your tool, any suffering component can have a domino effect that will damage neighboring parts along the electrical pathway. Thus, finding and fixing your problems before they spread should be the goal of every tool owner. Secondly, keep in mind that all of these malfunctions can feel very similar from the outside and that they may occur singularly or in any combination. Be familiar with your power tools and learn to understand their subtle cues. This will help you repair your power tools at the first signs of drag or malfunction. In the end, it is better for us all to process our little problems before they become out of control. Love your tools and I promise they will love you back.
