Belt stops when i walk on it

if it really is the walking belt that is slipping keep tightening the adjustment screws till the belt will not slip when you try to stop it ( set speed to about 3 and then with your foot try to stop belt from spinning - you should be able to make the motor and whole machine come to a stop ) make sure it is really walk belt spinning and it isnt the motor belt slipping. (if it is motor belt slipping when you try to do the stop the belt trick i just described you will see the walk belt and front roller stop but still hear the motor turning) once you get walk belt tight enough so it doesnt slip then you can worry about keeping the belt centered.

let me know if you need more help on this and let me know how the stop the belt test went

good luck!

Hello, There is no maintenace required. Some people like to oil the walk belt, The manual say to do this annually. To do this you loosen the walk belt and applty some synthetic oil to the walk board under the walk belt, then tighten the belt and the belt will distribute the oil where it needs to go. As far as the walk belt, just make sure that is stays in the center of the walk board. Now your front roller and drive belt. The roller does not get serviced, it has perminently sealed bearings. The drive belt usually lasts for many years, if you remove the motor hood and see alot of black dust, it will be the belt. At that point you need to see why it is comming apart/rubbing. After you determine that, you would want to replace it.

The slipping you are describing could be the drive belt slipping on the front roller or the drive pully on the front roller. To find out you need to remove the motor hood nad get on it and look. What you will be watching is the drive belt as it goes from the drive motor to the drive pully. When you try to stop the walk belt you will either stop the drive belt or stop the walk belt. If you stop both, the drive belt is at fault, if the motor keeps turning. If you stop the motor, the motor or the controller is bad. If you stop the walkbelt and not the drivebelt you have a bad drive pully on the front roller, and need to replace the front roller. When you do this you need to remove the drive belt, this is a ggod time to replace it.



Hope this helps, rate my solution if it helped you. Thanks, Matt

hi, if the belt is slipping then its too loose, if you can lift more then 2/3 inches off the base then its way too loose. at the back end of the treadmill there should be two bolts turn each one half way round and try walking if its still slipping then tighten them abit more until the belt stops slipping,

Unplug unit then remove motor shroud the walk on the belt normally and try to stall the belt to make it slip. Be careful during this test. If the problem is in the drive belt, either the drive belt will stop when stalled or the front roller will stop when stalled.
Find the set bolt(s) on the motor. This is typically run through only one side of the motor mount or may be on both sides but it does not run the full length of the mounting..
Look for a bolt that will tension the motor. If it has this bolt, it typically runs in the same direction parallel with the drive and walking belts. If your treadmill is not equipped with a bolt as described above, the drive belt must be tensioned by hand. While one person applied increased tension to the drive belt, the other person should tighten the motor set bolt(s) that are described in Step If your treadmill is equipped with this bolt (very few are) the repair will only require one person.
If the motor, drive belt, and front roller continue to turn when the walking belt is stalled, the problem is with the walking belt slipping on the front roller.
If the walking belt slips when walked on. Using the allen wrench, turn both rear roller bolts clockwise, 1/4 of a turn. When the walking belt is correctly tightened, you should be able to lift each side of the walking belt 3 to 4 inches off the walking platform. Be careful to keep the walking belt centered. Plug in the power cord, insert the key and carefully walk on the treadmill for a few minutes. Repeat until the walking belt is properly tightened.

Hi James
Unplug unit remove motor shroud then plug unit back in , press start and begin walking on the belt normally and try to stall the belt to make it slip ( planting foot to stop the belt).
Be careful during this test. If the problem is in the drive belt, either the drive belt will stop when stalled or the front roller will stop when stalled. Here is the procedure for adjusting the drive belt.
Find the motor mounts. Many motors in Icon treadmills have a main pivot joint in which a bolt runs the full length of the motor mount. This bolt will require loosening to provide maximum adjustability. Some models have a single jack bolt and others have an auto tensioner. Single jack bolts are the easiest to adjust.
Find the set bolt(s) on the motor. This is typically run through only one side of the motor mount or may be on both sides but it does not run the full length of the mounting. Loosen this bolt(s) but do not remove. Jack bolt models will have flat mounts and may contain up to four bolts.
Look for a bolt that will tension the motor. If it has this bolt, it typically runs in the same direction parallel with the drive and walking belts. If your treadmill is not equipped with this bolt, skip to Step 4. If your treadmill is equipped with this bolt (very few are) the repair will only require one person. Using 2 7/16" wrenches, make a few turns to this bolt, tighten the bolts and test your treadmill for slipping. If belt continues to slip, and if their is too much tension ( you should be able comfortably twist the drive belt 90 degrees ) then replace drive belt.
If the motor, drive belt, and front roller continue to turn when the walking belt is stalled, the problem is with the walking belt slipping on the front roller, here the procedure adjusting the walking belt.
If the walking belt slips when walked on, first remove the key and UNPLUG THE POWER CORD. Using the allen wrench, turn both rear roller bolts clockwise, 1/4 of a turn.When the walking belt is correctly tightened, you should be able to lift each side of the walking belt 3 to 4 inches off the walking platform. Be careful to keep the walking belt centered. Plug in the power cord, insert the key and carefully walk on the treadmill for a few minutes. Repeat until the walking belt is properly tightened
If the drive belt continues to turn but the front roller stalls, you may have a broken front roller pulley. If this is the problem, you will notice it because the plastic will usually make a loud squealing sound on the metal front roller. The front roller assembly will need to be replaced and the drive belt must be replaced also. We suggest replacing the drive belt as well because it is a low cost item and will most likely, have suffered unusual wear from the problem. Another possibility is that the drive belt has worn down. In some cases, belt dressing may help correct the problem. If not, the drive belt must be replaced.

If belt hesitates or slips when walking on unit it may be caused by either a loose walking belt or a loose drive belt. To determine the cause perform the following test: Stand beside Tread-Climber® fitness machine and set speed to 2 MPH. Step on one treadle and attempt to stop movement. If one belt stops but roller at rear and other belt continue to turn walking belt tension should be adjusted. If both belts stop but motor is still turning the drive belt tension should be adjusted.
Adjust walking belt tension at the front of the unit using the provided hex wrench on the exposed adjustment bolts located on each side of each front roller. Be sure to adjust both bolts on each roller the same amount as to not disrupt belt alignment. Tighten (turn clockwise) each adjustment bolt in full turn increments. After each adjustment, restart unit and check to see if belt slippage has been eliminated. Repeat if necessary.

Unplug unit then remove motor shroud then do the following: If the problem is in the drive belt, either the drive belt will stop when stalled or the front roller will stop when stalled. If the motor, drive belt, and front roller continue to turn when the walking belt is stalled, the problem is with the walking belt slipping on the front roller. If the drive belt continues to turn but the front roller stalls, you may have a broken front roller pulley.

1) Adjusting the running belt if the problem: If the walking belt slips when walked on, UNPLUG THE POWER CORD. Using the hex key, turn both idler roller bolts clockwise, 1/4 of a turn. When the walking belt is correctly tightened, you should be able to lift each edge of the walking belt 2 to 3 in. off the walking platform. Be careful to keep the walking belt centered.Then, plug in the power cord, insert the key, and carefully walk on the treadmill for a few minutes. Repeat until the walking belt is properly tightened.
2) Adjusting Drive belt: Find the motor mounts. Many motors in Icon treadmills have a main pivot joint in which a bolt runs the full length of the motor mount. This bolt will require loosening to provide maximum adjustability. Some models have a single jack bolt and others have an auto tensioner. Single jack bolts are the easiest to adjust.

If the walking belt slips when walked on, first remove the key and UNPLUG THE POWER CORD. Using the hex key, turn both rear roller bolts clockwise, 1/4 of a turn. When the walking belt is correctly tightened, you should be able to lift each edge of the walking belt 2 to 3 in. (5 to 7 cm) above the walking platform. Be careful to keep the walking belt centered. Then, plug in the power cord, insert the key, and carefully walk on the treadmill for a few minutes. Repeat until the walking belt is properly tightened.If you still have slipping then the drive belt under the motor shroud can also cause this problem unplug unit remove shroud then plug unit in start it up observe the front roller to see if it stops if it does locate the tension adjusting bolt by the motor loosen motor mount and proceed adjusting until slipping has been eliminated

Sometimes tightening the belt is not the problem> What I would be doing is to get on the machine a determine which of the belt is actually slipping. What happens if the drive belt is glazed slippage occur no matter what you do. With the running belt you may have to it limits of adjustment and the belt can be stretched that no matter how you adjust it it will slip!!

When the belt slips, it can be 2 different places. The trick is to look at the front roller when the belt slips. If the front roller stops with the walking belt, then the drive belt (between the motor and front roller) is loose and can't be fixed by tightening the walking belt. If the drive belt is slipping, it needs to be tightened or replaced. I need the brand and model number to help you further.
