to change belt tension, the belt alignment must be maintained.

14. Place a belt gauge (Precor part # 20030-117 or equivalent) in the middle of the step up belt
at the center of the belt span (see Diagram 5.4). Lay a straight edge along the length of the
belt and beside the belt gauge. Slide one of the o-rings up against the shoulder of the belt
gauge. Press downward on the belt gauge, causing the belt to deflect. Read the deflection
on the belt gauge at the edge of the straight edge. Deflect the belt 1/4”. Read the tension
across the top edge of the o-ring. If the belt is correctly tensioned the gauge will read
between 14 and 16 pounds.
15. If the tension in step 14 is correct skip to step 18. Otherwise continue with the next step.
