Because they are wear items, after months or years of using your tool the brushes will gradually wear away due to repeated exposure to friction and heat. Worn brushes can easily be the cause of intermittent motor function, reduced motor power and reduced electric braking. A worn out brush will commonly be most worn down near the wire lead and may be pitted, cracked or burned. When you replace the carbon brushes, make sure to also inspect your armature for cracks, burns or other damage which often indicates a more serious problem with the motor.

You might need some new motor brushes. The brushes are made of carbon and have a lead wire and spring attached to them. The brush conducts electricity to the armature through the commutator. Because the brush is in constant contact with the rotating commutator, it will wear down with use and need to be replaced. A worn-out brush may not contact the commutator, which will prevent the saw from turning on.

Sometimes a worn brush will make weak contact, which can cause excessive sparking from the armature. Let's get started. Unplug the saw. Disconnect unplug the saw from its power source.

In most motors, they seem to last forever because they get so little wear. In motors that are used often or under heavy loads, like routers, for example, they do wear down. As long as the motor is running properly and seems full of pep, there is probably no good reason to replace the brushes.

However, inspection is important. The brushes are just pieces of carbon. If the brushes wear down to the end, the metal holders that carry them can cut into the motor armature and cause damage. Any motor that shows big blue sparks, or seems not to have the full power it should is likely past due for brush care.

New brushes are commonly available as replacement parts. Otherwise, keep them blown out clean and keep using the tools.

Off-and-On Use Switches - Wearing power switches will cause off-and-on use as their connections wear down, sometimes requiring several pulls of the trigger before the tool starts up. Decreased Tool Power Switches - The gradual wear of power switches can sometimes cause a decrease in power that reaches the tool's motor.

Sometimes this decrease in power happens without warning signals like off-and-on use. This makes diagnosis difficult at first, but a switch acting like this will quickly get worse by reducing the power performance of the tool even more, making it easier to pin down the cause as time goes on.

Switches can also cause a decrease of tool power when they have suffered heat damage but not shorted out completely.The motor brushes transfer electricity to the motor armature to turn the motor shaft.
