User Tips:

• You should check both motor brushes after every 50-60 hours of use. Simply unplug the tool, open the brush caps and remove the carbon piece from the holder. If there is less than 1/8" of carbon left on either brush, they both should be replaced.
• We offer a variety of motor brushes, but you should only use the motor brush that is compatible with your tool. Two motor brushes are included in each pack.
• Motor brushes consist of a coiled spring of metal with a piece of carbon at the end. They go under the brush cap and rest on the armature, providing the electrical connection to keep the tool running.
