ALIGNING THE BELT—PART ONE
To align the belt, turn the Left & Right side adjustment bolts one full turn clockwise using
the Allen Wrench that your model came with. Continue the process until the belt is at the correct alignment. Make sure to adjust both sides equally to ensure a correct belt alignment.
ALIGNING THE BELT—PART TWO
Place the treadmill on level ground and set it at 3-5 mph to check if the running belt drifts. If your
running belt drifts to the left or right, follow these instructions to align the belt.
If the Running Belt moves to the right, turn the adjusting bolts on the right side 1/2 of a turn clockwise, then turn the left adjustment bolt 1/2 of a turn counterclockwise. If the belt does not move, repeat the step until it centers.
If the Running Belt moves to the left, turn the adjusting bolts on the left side 1/2 of a turn clockwise, then turn the right adjustment bolt 1/2 turn counter-clockwise. If the belt does not move, repeat this step until it centers.
TIGHTENING THE BELT—PART THREE
Some treadmills require you to tighten the belt through the case. Remove the case of the treadmill and use an Allen Wrench to tighten the belt.
Remove all the screws from around the treadmill. After removing all the screws that connect the case to the treadmill, lift the case.
On the left side of the case, you will see a screw that you can tighten using an Allen Wrench. (see below image)
