5. Observe the Cybex logo position relative to the belt tracking slots with the treadmill running at 5 mph
(8 kph).
While centering the running belt choose one bolt to adjust. Do not adjust both bolts.
6. Tighten the rear roller bolt on the side of the treadmill toward which the running belt is moving using
a 3/4" socket wrench.
For example: If the running belt moves to the right of the belt tracking slots, tighten the bolt on the
right side of the frame, tighten about 1/2 of a turn (clockwise) and wait 30 seconds. If the running
belt does not move back to the center of the belt tracking slots, make another adjustment to the
same bolt. Once the running belt has been adjusted closer to the center of the belt tracking slots,
use about 1/4 of a turn until the running belt has been stabilized.
7. Check the belt tension after the running belt has been centered.
Make sure the running belt tension is tight enough so that the running belt does not slip or hesitate
when stepped on. Walk on the treadmill at 3.5 - 4 mph (5.6 - 6.4 kph) and every 4th to 5th step throw
your weight into your step to feel if the running belt is slipping. If slipping is felt, confirm it is the
running belt slipping and not the drive belt. With the hood cover removed, observe movement at the
drive belt and front roller.
Do not over tighten the running belt. Over tightening the running belt can cause the belt to stretch
and require replacement. Continue procedure until running belt stops slipping.
8. Check running belt for centering position.
If running belt is not centered, perform steps 5 and 6.
