They are sometimes a little noisy to start with so it is best to run
in the motor by continuously running it for 4 days on 33rpm.
Do not run at over 78rpm as this can harm the brushes over
prolonged periods.
Most importantly you can “tune in” the motor to give minimum
noise by adjusting the tightness of the screws next to the motor
pulley. The best way to set their tension is to tighten the screws
until they just nip tight. Then back off all the screws a little
way. Now tighten one screw at a time till you hear which
ones cause the least noise when tensioned and then adjust the
other(s) to give minimum noise. If it continues to be very noisy
please contact Origin Live. However, bear in mind that dc
motors are rarely as silent as a/c motors.
The other major potential source of noise is a lack of pod top
plate tightness or motor fastening tightness. This can cause the
top plate to resonate. The solution is usually to slightly tighten
the small screws holding on the motor. This adjustment is
fairly critical - if the small screws are too tight then the motor
whispers, too slack and the motor can vibrate against it’s top
plate.
If you get a knocking sound from the motor then slightly
slacken off the screws holding the motor to the top plate.
If you have checked the above and are still having trouble please
