Motor Brush Replacement

The two (2) motor brushes should be replaced when they are worn down to less than 1 inch in length. Replacement brushes are “pre-worn” by the manufacturer and require no break-in period.

Caution! Disconnect power to the Additive Feeder before changing the motor brushes.

1. Remove a brush cap screw near the back of the motor.

Caution! The motor brushes are spring loaded. Use care to avoid eye injury when removing the cap screw. Wear safety glasses when performing this procedure.

2.Remove the brush. Make note of the direction of the tapered end of the brush face.

3.Insert the new brush (See Figure 5 below for Brush Part Numbers) with the tapered end facing the same way as the worn brush.

4.Secure the new brush with the cap screw.

5.Repeat the above steps for the other brush.

The motor is now ready for use.
