Running Belt Tracking Adjustment
14. Place a reference point on the deck right next to one edge of the running belt so that any
side to side movement can be observed, a white grease marker works well. Start the
treadmill and set the speed to 1 mph. Observe the running belt, if the belt starts to drift
toward the right, slowly turn the right side take up roller mounting bolt clockwise until the
drifting stops. If the belt starts to drift toward the left, slowly turn the right side take up roller
mounting bolt counterclockwise until the drifting stops. The adjustments should only be done
in 1/4 turn increments. NOTE: ONLY use the right side take up roller mounting bolt to adjust
tracking.
15. Increase the speed to 3 mph for a minute, then 6 mph, 9 mph and finally 12 mph, making any small
adjustments as needed.
16. Set the treadmill speed to 3 mph and walk on the treadmill for a couple of minutes. Verify that the
belt has not moved. Adjust the right side take up roller mounting bolt if needed to make final
adjustments.
17. Replace the end caps or rear guard and motor cover.
