Treadbelt Adjustment
4.2.1. Adjusting the Tension
The treadbelt tension is set at the factory. The belt may stretch
or be off-center after use. Stretching is normal during the
break-in period.
1. Use the supplied Allen wrench to turn both adjustment
screws independently clockwise by 1/4 turn at a time.
Ensure the treadbelt remains in the center of the walking
surface.
2. Plug in the power cord and carefully walk on the treadmill
for a few minutes. Repeat the adjustment if necessary.
Treadbelt is properly tensioned when the slipping sensation
is gone. DO NOT OVERTIGHTEN or damage to the belt
and other components may result.
4.2.2. Centering the Treadbelt
The treadbelt is adjusted at the factory, but may move off-
center during use. Before each use, ensure the treadbelt is
centered and remains centered during operation.
To center the treadbelt:
1. If treadbelt is too far to the left, use the supplied Allen
wrench to turn the adjustment screw on the left side 1/4 turn
clockwise.
2. Turn the treadmill on. Set speed to 2mph for 1 minute to
see if the treadbelt returns to center.
3. If the treadbelt moves to the right, turn the adjustment
screw counterclockwise by 1/8 turn. Repeat steps 1
through 3 until the running belt is centered.
WARNING
Grasp the handrails with both hands. With your
left foot on the ground, try to stop the treadbelt
with your right foot. If the treadbelt slips and the
motor idles, the treadbelt is too loose.
WARNING
Do not walk on the treadmill during adjustment.
