Belt Tension
Test the belt tension by running on the belt at about 4-mph. Hold the handrail lightly and resist the
belt movement with your feet. If you feel the belt slip on the front roller, then increase the tension of
each adjustment bolt by 1 turn and retest. Be sure to count your turns and tighten evenly.
