Most treadmills have two screws at the back of the treadmill that adjusts tension on the belt. If the belt is staying on the left side of the treadmill pad then adjusting the left ***** out should make it go back towards the center.
Adjusting Tension on a Treadmill Running Belt
It is necessary to properly tension atreadmill beltwhen 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 forhow to tension a treadmill running belt.
Adjust for no slippage of thetreadmill walking belton the front roller (Often referred to as the "Stomp Test")
This procedure works well for a previously installed belt that is now slipping.
Underside of belt should be free of any glazing/wax buildup.
Rollers must also be free of wax buildup.
Be sure belt tracking/centering is correct before proceeding.
The most popular speed for this adjustment is 2mph to 3mph.
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.
This procedure works well when installing a new belt.
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.
If you are working on a previously tensioned belt you will need to release the tension before attaching the gauges or calipers.
Gauges or Calipers unavailable
Release the tension on the belt.
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).
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.
Test for proper tracking and tension, adjust if necessary.

Loosen off the rear roller adjustment bolts, 10 turns each side counterclockwise. Remove the motor drive belt. The front roller should now be removable. If you have difficulties, back off the rear roller adjustment bolts 3-4 turns further. Keep track of how many counterclockwise turns so you are able to readjust the belt after replacing the front roller pulley assembly. Repeat the instructions in reverse once the front roller is in position.
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.If slipping feel persists after several adjustments, stop and see if it maybe the drive belt.
Remove left rear plastic cover to expose “v” belt drive line and motor. Tighten nut on the motor tension bolt located on front side of motor in 1/2 turn increments until drive belt slippage is eliminated - DO NOT OVER TIGHTEN. Replace cover when finished.
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.
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.
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)
If the problem is in the drive belt, either the drive belt will stop when stalled or the front roller will stop when stalled.
Follow this procedure:
First remove the key and UNPLUG THE POWER CORD. remove motor shroud, then 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.
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 Tighten the bolt and test. If the problem is not corrected, repeat steps above and retest.
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.
Follow this procedure:
First remove the key and UNPLUG THE POWER CORD. Using the allen wrench, turn both rear roller adjustment 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. Rear Roller Adjustment Bolts
If the drive belt continues to turn but the front roller stalls, you may have a broken front roller pulley and front roller must be replaced.
Follow this procedure:
First remove the key and UNPLUG THE POWER CORD. remove motor shroud. Loosen the rear roller and remove the two adjustment bolts. Some models have a spring loaded tensioner on the right hand side so be careful when removing these bolts. After the bolts have been removed, remove the rear roller end cap(s). The rear roller should now simply slide out of the walking belt.
Remove the motor hood. Using a black permanent marker, make a mark on the front roller adjustment bolt on the motor compartment side at exactly where it fits flush with the roller so you will know where to retighten it later. The adjustment bolt is on the right hand side of the front roller. Then remove the bolt with a 7/16” wrench. then remove front roller and replace with new reverse procedure mentioned above
The rollers in the front and rear need to be adjusted. If its sliding to the left, than the left side needs to be adjusted out until the belt stops going that way and stays on straight.
