the drive belt is too loose. you need to tighten the belt that drives the front rolller, which drives the walking belt. depending on the type of treadmill there shoudl be a way you can do this by loosening the motor and adjusting that to tighten the belt. it could also be that the belt needs to be replaced and also could be the walking belt. you should try to tighten the walking belt first. that is at the end of the treadmill where you walk on it. there are two holes one on each side of the treadmill where teh belt goes back under the treadmill. there are allen key bolts that you need to tighten clockwise one turn then try the treadmill. if it doesnt tighten then turn another full turn. if not tight enough then it might be the drive belt. if you tighten the walking belt all the way then try to tighten the drive belt.

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.

Sounds like either the belt is loose or the belt/deck need to be lubed.

To lube the treadmill, use silicone spray and spray between the belt and deck on both sides. I hope this helps. Let me know if you have any other problems.
