    TREADBELT TENSIONING Treadbelts are tensioned at the factory and normally need no adjustment. To determine if the treadbelt needs to be adjusted perform the following test: 1. Remove motor cover. 2. Set treadmill speed to 2mph. 3. Walk on treadbelt and see if drive roller is turning but belt is not moving. If belt is not moving then tension treadbelt ONLY until belt ceases to slip.
