Adjust Motor Belt - Kettler Atmos Pro Instruction Manual

Adjust Motor Belt

After a period of time, the user will feel there is a pause
sensation whilst running. That may be due to a loose drive
belt, so adjusting the motor belt would be necessary. First of
all, you have to check if it is loose following the steps below:
Check If The Motor Belt Is Loose
1. Unplug the treadmill.
2. Remove the motor cover by unscrewing the bolts on each
side. You will see the motor located on the left hand side of
the treadmill.
3. The easy way of checking is by touching the drive belt to
feel if it is slack. If you can wiggle the belt up and down, it
means that the drive belt is loose.
4. Another way of checking is setting the speed at 2-3 km/h.
Walk on the machine and try to stop the running belt with
your feet while holding the handrails and pulling your
body on the opposite direction. If the motor pulley stops
and the front drive roller keeps running means that the
motor belt is loose and it needs to be tightened.
