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.

How to Tension Treadmill Walking Belt that Slips

The side the belt is running to is the side you adjust first.
Turn the machine on to 2 kph.
Stand with 1 foot on the side rail
Try and stop the belt with the other.
If you can stop it tighten both sides 180 deg clockwise.
Repeat test until you can not stop the belt.
Now it is tight.
The rear roller has to be even to keep the belt from running to 1 side.
If you have turned 1 side more than the other the belt will run to the other side.
Hope this helps.

Dear Sir:
I can read you trouble, and follow the next steps:
ALIGNING AND ADJUSTING THE RUNNING BELT
The correct alignment of the running belt is critical to the smooth operation of the treadmill. The belt is properly aligned at the factory. However, during shipping and handling or by use on an uneven surface, the belt may move off center and require a few simple adjustments. Before aligning the running belt, check its operation by following the procedure in Checking the Alignment of the Running Belt. If you determine that the belt needs alignment, follow the instructions here. CAUTION: Special care must be taken when aligning the running belt. Turn OFF the treadmill while adjusting or working near the rear roller. Remove any loose clothing and tie back your hair. Be very careful to keep your finger or any other object clear of the belt and rollers, especially in front of the roller and behind the deck. The treadmill will not stop immediately if an object becomes caught in the belt or rollers. Realigning the belt takes a few simple adjustments. If you are unsure about this procedure, call Precor Customer Support (see Obtaining Service.) Take the following steps to align the running belt on the treadmill. To ensure your safety, make all adjustments while the treadmill is OFF. 1. Make sure the treadmill is OFF and the running belt has completely stopped. 2. Locate the right belt adjustment bolt in the rear end cap of the treadmill. (To determine left and right, stand at the rear of the treadmill and face the display.) See Diagram 24. The direction you turn the bolt depends on how the belt is tracking. Make all belt adjustments on the right rear corner bolt using the hex key provided. • If the belt is off center to the RIGHT, turn the adjusting bolt ¼ turn clockwise, which moves the running belt to the left. • If the belt tracks off center to the LEFT, turn the bolt ¼ turn counterclockwise; this moves the belt to the right. Important: Do not turn the adjusting bolt more than ¼ turn at a time. Overtightening the bolt can damage the treadmill. 3. Turn the unit ON. 4. Stand beside the treadmill and press QUICKSTART. 5. If you are prompted for a password, press INCLINE ??¼, SPEED ??¼, SPEED ??². The running belt starts automatically after the 3-second countdown appears on the display. 6. Press the SPEED ??² key until the display shows a speed of 3 mph (5 kph). 7. Walk around to the rear of the unit and observe the running belt for a few minutes. The belt should run centered along the running bed. If the belt drifts off center, you will need to make adjustments. CAUTION: If you hear any chafing or the running belt appears to be getting damaged, stop the running belt immediately by pressing the red STOP button. Contact Precor Customer Support. 8. If the belt needs additional alignment, repeat steps 1 through 7 until the belt is properly aligned. 9. After aligning the belt, press the STOP button and RESET. Turn OFF the treadmill. Tighten any loose fasteners or other components on the equipment. If you hear unusual noises or you feel that the treadmill is in need of repair or service, contact Precor Customer Support. Refer to Obtaining Service.
Finally, check if the power cord is loose, connect it again. a) See if the breaker of Home is tripped? b) See if the breaker of the Treadmill is tripped. If do the Belt is very Tighted! loose a little. Try again.
Thank you in advance, if you need assistance, you can contact me, Blessing. sincerely.

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.

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

Remove left side plastic drive cover to expose “v” drivebelt. Loosen nut on the motor tension bolt located on front side of motor in ½ turn increments until drive belt loose .If belts move with drive belt loosened but do not move when it’s tight motor is seized. Replace motor.

At the end of of the running belts in the end caps will adjusting bolts you will need a allen wrench to adjust the tension. Start your treadmill and turn clockwise a 1/4 turn each time see i f you can stop the belt. You need to be aware that the drive belt can also cause this problem so I suggest that you remove the motor shroud and when you are adjusting whether the front roller is moving and the running belt has stopped or the roller has stopped and motor is rotating ( adjust Drive Belt)

Either front roller may need to be replaced or the motor drive belt may need to be adjusted. This problems are caused when a walking belt is worn out and in need of replacement. Too much tension can cause bearing failure in the motor and the front roller and front roller pulley failure.

Motor drive belt adjustment: The motor drive belt is adjusted independently from the walking belt. Some newer models have an auto tensioner which is a lever that has a wheel that puts pressure on the drive belt and a spring on the other end that automatically loads the belt to the proper tension. You should not adjust these since they are preset. Tension can be affected slightly by adjusting the tension of the walking belt but if you have a slipping problem, the drive belt will require replacement. If your drive belt is too loose, it will slip on the front roller pulley or the motor pulley. If it is too tight, it will increase your amp draw to the point that you may have an electronics or motor problem. Due to this, it is better to be on the safe side and replace a drive belt rather than risk over tightening it.
