SOURCE: The track of our image 19.0r treadmill slips when

I had the same problem..the fix was easy. Remove the cover from the motor area, examine the belt(its on the right). My belt was simply loose. I took a wrench (1/2 or 9/16 I think)...loosened the bolt, wedged the motor so that the belt was tighter, and tightened the bolt. Volia. Cured...Good Luck.

SOURCE: belt is slipping on healthrider treadmill

This is caused by one of three problems. First and most likely, the walking belt is loose. 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. If it takes more than 2 turns then something else is the problem. The second problem that it could be is the drive belt might be loose. To tighten the drive belt, start by removing the front cover. loosen the bolts around the motor then tighten the drive belt by tightening the motor adjuster bolt. Once the drive belt is tight, tighten the motor back down. The third problem that it could be is the walking belt could be worn and need to be replaced. Let me know if you have any questions.

SOURCE: I have a IMAGE 10.0 treadmill and the belt is

To tighten up the running belt, you need to increase the tension, by adjusting the 'tension bolts'. There are two of them. They are located at the back foot of the treadmill. (kinda like where the back bumper would be, if it was a car). Little black bolts. One on each side, and they require a hex key. Clockwise to tighten. Good Luck!

Belt keeps slipping on treadmill


Adjusting Tension on a Treadmill Running Belt It is necessary to properly tension a treadmill belt when it is replaced. After time, a belt can stretch and may begin to slip. When this happens, it is necessary to adjust the tension of the running belt to stop it from slipping. Manufacturers of treadmills generally agree on one of three procedures for how to tension a treadmill running belt.
  1. Adjust for no slippage of the treadmill walking belt on the front roller (Often referred to as the "Stomp Test")
    1. This procedure works well for a previously installed belt that is now slipping.
    2. Underside of belt should be free of any glazing/wax buildup.
    3. Rollers must also be free of wax buildup.
    4. Be sure belt tracking/centering is correct before proceeding.
    5. The most popular speed for this adjustment is 2mph to 3mph.
    6. Try to slow the belt by applying pressure with your foot against the belt movement while grasping the handrails. If the running belt slow, slips or stops (and the front roller does not) adjust BOTH adjustment bolts 1/4 turn clockwise. Test again and repeat adjustment if necessary.
  2. This procedure requires two belt gauges or calipers
    1. This procedure works well when installing a new belt.
    2. This procedure requires you to stretch the belt. Depending on the manufacturer*, this varies between .4 and .6 percent. A dial on the gauge or caliper will indicate the amount of stretch. *Consult the owner/service manual for proper tension.
    3. If you are working on a previously tensioned belt you will need to release the tension before attaching the gauges or calipers.
  3. Gauges or Calipers unavailable
    1. Release the tension on the belt.
    2. Using a yard stick or tape measure, place two marks on the left and right edges of the belt and deck 36 inches apart (or 50 inches if you prefer).
    3. Adjust the left and right tensioning bolts until both sides measure 36 3/16 inches (or 50 1/4). This is equal to .5% of stretch.
    4. Test for proper tracking and tension, adjust if necessary.

I have a pro form treadmill and it seems like the belt is sticking, its about 14 yrs old. I think I might need to replace the belt


kilgore511,

The most common cause of belt sticking or "slippage" is lack of lubrication. Most treadmill belts use lubrication on the underside of the belt to reduce friction between the belt and the platform. This helps the treadmill glide along smoothly under the weight of a person. If your belt is lacking in lubrication, it can catch on the treadmill platform. Apply lubrication every few months to the underside of the belt to prevent this from occurring.

A petroleum or silicone based lubricant is recommended, and most easily applied in a spray can. Simply lift up the belt about midway along the platform and spray a small amount of lubricant underneath from about the middle of the platform width to the closest edge. Repeat from the other side. Apply lubricant sparingly...it can be messy.

Next, turn on the treadmill and let it run for a minute, then check if the belt still sticks. A little more lubricant may be necessary.

If you have found this helpful, please take a moment to give me four thumbs up.

Regards,

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) 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.

The treadmill belt is making a noise and feel like it hesitates for a second while I am walking.


If it has a low pitch growling when you start unit then the running belt is too tight and the adjusting bolts need to be backed until the growling noise is lessened or eliminate without the running belt slipping.
If it is the drive belt slipping, the adjustment bolt is underneath the frame so you will need to elevate the treadmill and adjust the bolt until slippage is eliminated without over tightening the drive belt.

The belt has moved over to the right side of the treadmill.


Here are two solutions one is to get the belt centered on the treadmill and the other is to tighten the belt.

There should be two bolts in the rear of the treadmill, one on each side. These bolts adjust the rear roller of the treadmill. The walking belt will always go to the side that is looser. To get the belt back on track, (if you can start the treadmill so the belt is running) tighten the bolt on the side that the belt has slipped to. Tighten the bolt a little bit at a time. If you tighten the bolt too much, then the belt will go to the other side.

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.

As far as the manual, I have not been able to found anything yet.
