Noises generated under motor cover
Possible causes:
1. The running belt tension is adjusted too tight.
2. The bearing of front roller is not installed correctly.
3. Dirty grooves of drive belt.
4. The motor is damaged.
Fix:
1. Adjust the belt tension so
that the belt does not
start slipping and then
check if the noise has
disappeared.
Let the treadmill run,
without using it, for at
least 5 days because
sometimes the bearing
will settle and become
quiet then check if the
noise has disappeared.
2. Replace the front roller with a new one to see if the noise disappear.
3. Remove drive-belt and check the grooves in belt for dirt or dust and clean
if necessary. Clean also the motor pulley and the roller pulley grooves
and check if the noise has disappeared.
4. The motor bearing is damaged.
(Refer to "motor bearings replacement procedure"……page 8-22 ~
