Adjust the running belt
If you are running with a treadmill that is slippery or not smooth, you can adjust the tightness of the
running belt to improve.
How to adjust the running belt
1. Insert the 6mm hex wrench into the adjustment screw on the left side of the running belt and turn
the wrench 1/4 turn clockwise to adjust the rear roller to tighten the running belt.
2. Repeat step 1 to adjust the right screw. It must be determined that the adjustment screw rotates
the same distance so that the rear roller is adjusted parallel to the frame.
3. Repeat steps 1 and 2 until the running belt does not slip.
4. Note that the running belt cannot be adjusted too tightly. This will break the running belt,
increase the pressure of the front/rear drum, cause damage to the roller bearing, etc., causing
abnormal sound or other problems.
If you want to reduce the tension of the running belt, turn the wrench counter clockwise, paying
attention to the same distance between the left and right sides.
Run to the middle
When you use the treadmill, the pressure on the two belts is not the same when running, and the
pressure on the running belt is unbalanced, causing the running belt to deviate from the centre. This
deviation is normal, and when no one runs on the run, it will return to the center. If you don't get
back to the center, you will need to bring the belt back to the center.
1. Run the treadmill at no load and adjust the speed to 6km/H.
2. Observe the distance from the running belt to the left and right side bars
If it is to the left, use a hex wrench and turn the left screw 1/4 turn clockwise
If it is to the right, use a hex wrench and turn the screw on the right clockwise 1/4 turn
If the running belt is still not in the middle, repeat the above action until it is adjusted to the
middle.
3. After adjusting the running belt to the middle, adjust the speed to 12KM/H, and observe the
deviation of the running belt and the smooth running condition. If there is any deviation, repeat the
adjustment steps.
Caveat! Do not over tighten the rollers! This will result in permanent bearing damage!
If the above steps do not work, you will need to tighten the running belt.
