DRIVE MOTOR BRUSHES

1.Unplug treadmill!

2.Remove motor brush caps (2) with large flat head screwdriver.

3.Remove motor brushes and inspect. They should be replaced if 1/4 inch or less. Inspect motor commutator for wear (black-scoring present on copper segments). Try to dress out (clean up) commutator with a commutator stone or emery cloth.

4.When you reinstall motor brushes make sure the brush does not bind up in its holder. The motor brush must move freely the full length with zero resistance. If resistance is present you must carefully dress out the brush until the correct tolerance is achieved.

Motor brushes should be checked every 6 months on institutional treadmills and after 5 years on home units.
