Noises Generating From Under Motor Cover
Possible causes:
•
Verify proper tension of the running belt. Excessive noise may be created by
an over-tightened running belt.
•
Remove motor cover and verify alignment of drive belt.
•
Inspect for debris on drive motor pulley, front roller pulley, or on drive belt
•
If this problem is being experienced on a new treadmill, let the treadmill run for
about 30 minutes without load to break the treadmill in.
•
Remove the brush covers on the drive motor and inspect the brushes and the
motor commutator for any uneven wear.
(Make sure the treadmill is turned off before doing this procedure.)
•
If the surface of the motor brush is pitted, rough, or has burn marks, replace the
motor brush and stone the motor commutator.
•
Do not plug in the power cord and do not turn on the treadmill when the motor
brushes are removed from the drive motor.
•
After you replace a motor brush, make sure the brush is seated securely and
makes full contact with the commutator before you plug in the power cord and
turn on the treadmill
•
If the problem persists, replace the drive motor or front roller.
