My treadmill work fine when i turn it on but when i step on it the blet. slows down to crawl.


What make/model is the treadmill? What speed does this behavior occur? Does the walking belt slip, while the motor and rollers continue to turn? If the walking belt is slipping then the motor belt needs to be tightened. If the walking belt slows with your weight on it, does this happen at 1-3 mph and still occur at 4-5 mph? It could be your body weight causing it to slowdown, try to increase the speed to 4 or 5 and see if it still happens. If so, is the treadmill rated for your body weight? Please be more specific.

Treadmill slows suddenly and when i step off it starts again. only happens to me.


hi it sounds like the belt is too loose, i had the same problem when the wife uses the treadmill works perfect, untill i step on it really slows down and once i step off it runs fine. so i tightened the belt just a fraction and now works fine. check your instruction manuel it will explain how to do this. normally its two screws at the backend of the roller. hope i have helped.

Belt is not the correct speed when you put ypur weight on it...slows down.have to put on 5 to get a 3 walk?


If the walking belt is overtightened, treadmill performance may decrease and the walking belt may become damaged. Remove the key and UNPLUG THE POWER CORD. Using the hex key, turn both idler roller bolts counterclockwise, 1/4 of a turn. When the walking belt is properly tightened, you should be able to lift each edge of the walking belt 3 to 4 in. (8 to 10 cm) off the walking platform. Be careful to keep the walking belt centered. Then, plug in the power cord, insert the key, and run the treadmill for a few minutes. Repeat until the walking belt is properly tightened. . If the walking belt still slows then lubricate running deck the lube may be purchased from iconfitness.com

After walking about 15 seconds the belt slows way down and stops completely.


The walking belt slows when walked on the walking belt maybe overtightened, treadmill performance may decrease and the walking belt may become damaged or the opposite the drive and /or running belt may need tightening. Last thing would be that the belt needs lubrication to be applied between belt and deck.

The drive belt was loose. I tightened up the motor just a smidge using a crow bar. That solved the problem.

Sounds like either the belt is loose or the belt/deck need to be lubed.
To tighten the belt, start by locating the two bolts that adjust the rear roller (one on each side of the unit in the back). Run the unit at about 3 mph. Tighten the bolts a 1/4 turn at a time. Make sure that what you do to one side, you MUST do to the other side or the belt will get off center. After you tighten it 1/4 turn, check the belt to see if it is still slipping. If it is then tighten the belt 1/4 turn again. Continue until the belt does not slip, but do not tighten the bolts more than 2 full turns.
To lube the treadmill, use silicone spray and spray between the belt and deck on both sides. I hope this helps. Let me know if you have any other problems.
