Always disconnect power to the machine before performing maintenance. Failure to do this may result in serious personal injury.
Router maintenance is simple. Keep the router free from dust, dirt and grease and always store it in a dry place. Plastic parts can easily be cleaned with a damp cloth, but never use water to clean any electrical parts. Solvents should also be avoided on plastic because of the possibility of damage.
Inspect the router for loose parts, dam- aged cord or switch, and inspect the bits for chips or cracks. Replace the bit if it is worn or damaged. Continuous use of a worn or damaged bit will not only decrease working efficiency, but also overload the motor, so the bit must be frequently checked.
With the exception of the motor brushes, the electrical components of this router are not user serviceable.

Motor brushes will become loaded with carbon deposits or wear out over time. Extend the life of the motor brushes by removing them periodically and cleaning off the carbon deposits.
If the motor will not run, makes squealing or grinding noises, or performance is dra- matically decreased, check to see if the motor brushes need to be replaced. When replacing the motor brushes, replace both at the same time.
To replace the motor brushes:
1.Remove the caps on the sides of the motor housing as shown in Figure 22.

2.Replace the motor brushes and re- install the caps.
