I have the same problem with this type of treadmill but only when running on it. I usually increase the incline to prevent it. I believe the tension on the belt has become loose. I have been looking for a guide on how to tighten it but havent come across one yet. If i find one ill post back with the link.

While walking on my tredmill the belt jerks


Sometimes mine can "****" when my body weight on the front foot slightly slips the belt forward before I put full pressure on it and it slides back into normal walking. Don't know what your natural walking style is like, but this tends to happen when I am "heavy" on my heel with that forward step. Could also be that your belt needs lubricating (buy from sports stores).

Hesitation with the belt rotation. Less pronounced at faster speeds.


This is usually caused by a loose belt and can be tightened by the adjustment bolts located on the back of the machine on either side of back roller thru the holes in the shrouds

Belt squeaking and hesitating when I run


Before beginning this repair: Check to make certain that the drive belt requires adjustment. Check out belt slipping instructions or with the motor cover removed, 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. 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.
Step 1- 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. Step 2- 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. Step 3- 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 from Steps 1 and 2 and test your treadmill for slipping. If belt continues to slip, repeat Steps 1, 2, & 3. If a second attempt does not repair the problem, skip to Step 5. Step 4- If your treadmill is not equipped with a bolt as described in Step 3, 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 2. Tighten the bolt from Step 1 and test. If the problem is not corrected, repeat Steps 1, 2, & 4 and retest. If problem persists, skip to Step 5. Step 5- If you have arrived at this step, let's make sure you have a drive belt tension problem. With the motor cover removed, 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. 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. 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. Step 6- The belt should be able to be turned by hand at approximately a 90 degree angle from its normal operating position

When walking in my Bow Flexn as in regular treadmill mode it feels like it slips under my one foot sometimes any clue as to why ?


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.

When i walk on it the belt sticks in places and i cant let go of the rails


If your belt is sticking there are 2 possible causes. Either the walking belt itself is loose or the drive belt. The way to check is look at the front roller when you step on the walking belt. If the walking belt stops, but the front roller continues to spin, the walking belt is loose and needs tightened. If the front roller stops when you step on the walking belt, then the drive belt needs tightened or replaced. The walking belt can be tightened fairly easily, there are bolts at the rear of the machine that adjust the rear roller. The drive belt is a little more involved and requires removing the motor hood. Check to see what the front roller is doing and I'll help you further.

Nordictrack treadmill C2100 belk is not slipping motor stops when you step on treadmill at low speeds, step back off and it starts working


Several issues, drive belt that drives the walking belt could be loose but you should smell rubber if its slipping.
Something could be caught in the track causing extra drag, its easy to do if you have kids or pets
Check for when you last lubed the track and walking surface, with no silicone it will drag and bog at low speeds

Treadmil stops or slows down upon walking.


Check both belts to be sure they are adjusted and not slipping.Check the underside of the walk belt to see if it feels frayed in the center as compared to the edges, the center always wears more than the edges a really worn belt must be replaced. if it is nor worn there is a wax lubricant for proform treadmills that can be purchased at retail stores that sell treadmills.Sears, dicks sporting goods and also treadmilldoctor.com are good places to buy it.
