Action To Sliding Belt Problem

Usually running machine skid or sliding phenomenon results from two areas: running belt and multi-groove belt

Cause A (running belt looseness) :

The running belt was not set well during the production at treadmill factory, or it was loosen causing plastic deformation after long time use, resulting in reduced friction between running belt and roller.

Cause B (multi-groove belt looseness) :

The multi-groove belt connecting the motor and the roller is not set well before leaving the factory, or relaxed after a long time of use, resulting in insufficient tension, or too much lubricating oil under the running belt was thrown onto the inside of multi-groove belt , resulting in insufficient friction of the multi-groove belt.

After determining cause A or cause B according to the above operation, we should take corresponding countermeasures.

Countermeasure to cause A:

Unplug the safety lock (stop the machine) and turn the adjusting bolts on the left and right side respectively with 1/4 turn clockwise by using the inner hexagon wrench. Then insert the safety lock, start the treadmill and stand on the belt to check whether the sliding phenomenon still exists. Repeat the steps until the belt gains the right tension.

After the adjustment of tension of running belt is completed, you also need to make sure the running belt is centered. You could set the treadmill speed at 6-8km /h, running a few minutes, then to check. If it is not centered, use the inner six wrench to fine-tune one side (refer to the manual operation guide for details), until it goes the centered.

Countermeasure to cause B:

You should firstly check whether oil inside in multi-groove belt and the tension of multi-groove is adequate, then take action accordingly.

Notes:

1.Check the belt tension by using a tension meter if available (normally the belt tension should be 40~60NW/ groove).

2.When loading and unloading a belt, you have to switch off the power instead of operating while the motor is running, which is very dangerous!

3.After adjustment, you should step on the running belt again at the speed of 8~10KM/H to check whether the belt slides.
