RUNNING BELT ALIGNMENT PROCEDURE
Review entire procedure before starting.
1. Connect the power cord and switch the power ON.
2. Start the manual workout and set the speed to 3 mph (5 kph).
3. Observe and verify that the running belt tracking remains centered. If not, make minor
adjustments to the right tension adjustment bolt to center the belt tracking. Only use
the right tension adjustment bolt to adjust the tracking as follows:
a. Belt drifts right:
Slowly turn the right side tension adjustment bolt clockwise in ¼ turn incre-
ments until the drifting stops. You may need to recenter the belt by carefully
bumping the belt to the left.
b. Belt drifts left:
Slowly turn the right side tension adjustment bolt counterclockwise in ¼ turn
increments until the drifting stops. You may need to recenter the belt by care-
fully bumping the belt to the right.
