Sportcraft tradmill are very safe. First check and make sure there are no recalls on you unit. Do that on line or call Walmart where you most lickly got you treadmill. Try lubing you deck wich is under the belt. This is something that needs to be done to stop friction... Frition may have worn down the motor. Get back to me
