Belt Adjustment - RebelDesk 1000 Owner's Manual

BELT ADJUSTMENT

You may need to adjust the treadmill belt by increasing or decreasing the belt tension or
centering the belt. The treadmill belt can be adjusted by turning the adjustment bolts. Turning
the adjustment bolts to the right tightens the belt and turning it to the left loosens the bolt.
Centering the treadmill belt
The belt is adjusted at the factory. With transport and time, however, it may become off
center. You can center the treadmill belt manually by following these steps:
A. Start the treadmill without anyone on the belt, increase the speed until it reaches 1 mph.
B. Observe whether the belt is positioned more toward the right or left side of the deck.
1. If toward the left side of the deck, then use the provided 8MM wrench to turn the left
adjustment bolt clockwise 1/4, or turn the right adjustment bolt counterclockwise 1/4.
2. If toward the right side of the deck, then use the wrench to turn the right adjustment bolt
clockwise 1/4, or turn the left adjustment bolt counterclockwise 1/4.
C. If the belt still is not centered, then repeat the above steps until the running belt is centered.
D. After the belt is centered, then increase the speed to 2 mph and verify that it is running
smoothly. Repeat the above steps if necessary.
If the above procedure is unsuccessful in resolving the centering issue, then you may need to
increase the belt tension.
Increasing the tension of the treadmill belt
If the treadmill belt is not centering or if it feels as though it is slipping or hesitating when you
plant your foot on it, then the tension on the belt may need to be increased.
A. Place the wrench on the left belt tension bolt. Turn the wrench clockwise 1/4 turn to draw
the rear roller and increase the belt tension.
B. Repeat STEP A for the right belt tension bolt. Be sure to turn both bolts the same number of
turns, so that the rear roller stays square relative to the frame.
C. Repeat STEP A and STEP B until the issue is eliminated.
D. Be careful not to tighten the treadmill belt too much as you can create excessive pressure
on the front and rear roller bearings. An excessively tightened belt may damage the roller
bearings and result in noise from the front and rear rollers.
