Treadmill Squeak

To Clean & Dress the Commutator of the Treadmill Motor

• Unfortunately, some of the 806, 807 & 808 Treadmills have a tendency to make a squeaking noise when the motor is run too slow because the brush in the commutator is not seated properly. This is not a regular occurrence—typically, only 1 out of 50 treadmills will experience this. We apologize for any inconvenience; however, if you do experience this the enclosed stone (along with the following procedure) will eliminate the noise.

Procedure:

1. First, turn the power off on the treadmill.
2. Next, take off the cover of the carbon brush on either side of the motor.
   Note: You only need to open one cover, either the front or the back.
3. Then, slowly release the tension brush spring.
   
4. Next, pull out the carbon brush and insert the stone into the brush holder.
   
5. Slowly move the treadmill belt in a counter clockwise rotation for approximately 20 spins of the commutator.
   
6. Remove the stone.
   
7. Put the carbon brush back into the brush holder.
   
8. Apply the spring tension.
   
9. Close the cover that you removed.
10. Now, the squeak should be removed.
