Treadmill Belt Adjustments
WARNING
SECURE LONG HAIR AND LOOSE CLOTHING BEFORE WORKING NEAR THE
TREADMILL WALKING SURFACE OR PULLEYS.
Belt Tension
Adjust the belt tension whenever the belt slips or moves unsteadily during operation. Start by
loosening the belt with the adjustment bolts.
1. Adjust the walking belt to .4% stretch. With the walking belt loose, place two marks
30.0 inches (750 mm) apart on each side of the belt, near each edge of the belt. The
belt must be loose enough for you to move it from side to side on the front or rear
roller.
2. Turn the adjusting bolts clockwise by equal amounts until the marks are 30 1/8 inches
(753 mm) apart (30.0 in./30 1/8 = .4% stretch). This should be about 6 full turns of
each adjusting bolt from the point where the belt begins to stretch.
Adjustment Bolts
3. Run the belt at 3 MPH and make any tracking adjustments by loosening the adjusting
bolt on the side where the belt is farthest from the adjustment bolt. Make small
adjustments (1/4- turn) until the belt is centered on the rollers.
4. Test the belt by running on the belt at about 4 MPH. Hold the handrail lightly and resist
the belt movement with your feet.
WARNING
DO NOT USE ALL YOUR WEIGHT TO RESIST THE BELT MOVEMENT. TOO MUCH
RESISTANCE APPLIED TOO LONG (MORE THAN TWO SECONDS) MAY SHUT
DOWN THE SYSTEM. (VARIOUS ERROR MESSAGES WILL APPEAR IF THIS
OCCURS. CYCLE POWER TO RESUME NORMAL OPERATION.)
