11. Carefully move the running belt so that you can see the dials easily while tightening the take up
roller mounting bolts. Tighten the take up roller mounting bolts alternately in order to evenly
tighten the running belt. Tighten bolts until the gauges read .55%, which is five and 1/2 lines past
the number 3.
12. Remove both gauges from the running belt.
Running Belt Tracking Adjustment
13. 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.
14. Increase the speed to 3 mph for a minute, then 6 mph, 9 mph and finally 12 mph, making any small
adjustments as needed.
15. 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.
16. Replace the end caps or rear guard and motor cover.
