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.

Three reasons my cause the belt slip:
1. The roller is small.
2. Uneven silione oil.
3. Belt is loose.
Just check them.

Why does the belt slip forward when I run on it?


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.
