just measure the diameter of the socket on treadmill and order a magnetic safety treadmill key.
Can get them on ebay but you would need to check the diameter of the sold key matches by contacting seller via ebay messaging.

It may not be sticking, but instead slipping on the front roller. You can resolve this by simply tightening the running belt. This adjustment will be done by using the rear roller.

alot of times you have to remove the wax spray nozel and clean as the wax hardens over it

hi,
Your treadmill walking belt need lubrication. For lubricating use Teflon silicon lubricant. To know how to lubricate the treadmill belt watch the following video.
OK

kilgore511,

The most common cause of belt sticking or "slippage" is lack of lubrication. Most treadmill belts use lubrication on the underside of the belt to reduce friction between the belt and the platform. This helps the treadmill glide along smoothly under the weight of a person. If your belt is lacking in lubrication, it can catch on the treadmill platform. Apply lubrication every few months to the underside of the belt to prevent this from occurring.

A petroleum or silicone based lubricant is recommended, and most easily applied in a spray can. Simply lift up the belt about midway along the platform and spray a small amount of lubricant underneath from about the middle of the platform width to the closest edge. Repeat from the other side. Apply lubricant sparingly...it can be messy.

Next, turn on the treadmill and let it run for a minute, then check if the belt still sticks. A little more lubricant may be necessary.

If you have found this helpful, please take a moment to give me four thumbs up.

It's possible that your treadbelt needs lubrication, or simply adjusting. Here is a tutorial on adjusting your treadbelt:

Here is one link to purchase a lube kit, there are probably many others online also:

Should you actually need to purchase a new treadbelt, I would try to identify which specific model of the Proform 530 you have from this list and then in the parts list for that treadmill scroll down to "Treadbelt"

Go to your local hard ware store and purchase silicone spray. Apply Lubricant by lifting one side of the running belt spray contents length wise starting at motor shroud to the back end repeat this process the other side. If this unit bogs down again then you will have replace the running belt and possibly the deck.

There are hex bolts on the bottom rear of both sides of your treadmill. Turn one side one direction and the other sides the other direction until the belt tracks in the middle of the platform.

OPEN MOTOR SHROUD SO YOU CAN BETTER INSPECT THE UNIT CHECK THE DRIVE BELT THEN I WOULD CHECK THE RUNNING BELT TO SEE IF THEIR IS ANY DEBRIS THAT THE BELT ITSELF IS SPLITTING SINCE YOUR SAY A THUMPING SOUND. SINCE KEYS FITNESS MADE THIS UNIT THEY ARE NO LONGER IN BUSINESS, BUT TREADMILL DOCTOR HAD PURCHASED THE PARTS. SO GO TO TREADMILL DOCTOR.COM THEY MAY HAVE THE PARTS YOU NEED

replace the drive belt
