SOURCE: How do you adjust the belt for a Weslo Cadence 815 treadmill?

Hi, I don't have a manual on your particular treadmill but most all treadmills use the same type of belt tension and tracking, which is an allen screw adjustment on the rear tension bar. One on either side. You should have been provided an allen wrench with your treadmill, if not then use one of your own the proper size. Make the adjustment with the unit running at its slowest speed. Clockwise tightens the tension and will draw the belt. Good Luck, this should Fixya!

SOURCE: treadmill powers up but belt will not rotate

Check to see if the motor is spinning. If not spinning, then use a voltmeter to find out the voltage of power going to the motor that spins the belt. See if you can rotate it by hand.

SOURCE: Belt slipping on 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.

How do i fix my belt, is bowing up on my NB 1500 treadmill?

There are two knobs on each side at the end of the treadmill deck. Twist those knobs to tighten the belt. You will need to tight both sides. The little meters show you the amount of tightening you have done. They're most useful for making sure you have both sides tightened the same; otherwise the belt will be lopsided and slide to one side or the other.

How do i tighten my belt on a ironman treadmill

Hey Joe, at the back of the treadmill, you have the rear roller. The roller has a tension screw in both sides that are the adjusters as well. As you tighten the right side it will force the belt to the left, and vice versa. I turn the walk belt on to speed two, be carefull the belt will be moving. Slowly adjust one side and watch the belt move, then the other side until it centers. Shut it off, the belt should lift from the middle no more than two inches with a firm lifting force. That's it. You might need to tweek it to keep it centered.

Hope this helps, Matt

Belt is off center

Tighten the rear adjusting bolts until the walk belt it tight enough to lift about 1.5 inches at the sides of the walk belt. After you do this, Turn the treadmill on to speed setting 2, and be ready to tighten the side that the belt is closest to.( if the belt is against one side, start with that side) Tighten only 1/2 a turn at a time and watch the belt start to move. It wont take much once it starts to move. Only tighten each side ( if necessary) dont loosen the bolts. Once the belt is in the middle, leave it alone. The belt is now adjusted. You may see it travel to one side, breifly, but it will return on its own.

Belt is all the way over to the right instead of in the center. belt wont move. I hear motor running. How do I get the belt to the center. A neighbor gave me this treadmill with no manual. It worked for a...

To get the belt to the center you will see two adjustment bolts on the very back of the machine that require an allen wrench to adjust. Whichever side the belt is going towards is the side you will need to tighten. The best way to do it is to turn it a half of a turn then try and run the machine. if that does not help then loosen the other side a half turn, continuing until it pulls that belt back to the middle.

Belt is slipping,

It might just need a simple adjustment of the running belt that can eliminate the slipping refer to you owner's manual for the procedure. It will be close to all treadmill running belt adjustments.
Here is a generic procedure for adjusting the belt:
If the walking belt slips when walked on. Run the treadmill @ 3 to 4 mph, walk for a few minutes, Using the allen wrench, turn both rear roller adjustment bolts clockwise, 1/4 of a turn. Then repeat adjusting procedure until walking belt is properly tightened.

Track sliping

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.

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.

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.

The belt on my treadmill is off to one side. how

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.
