How to fix a ProForm Treadmill walking belt that slips?
- BBarry GonzalezJul 29, 2025
If the walking belt slips when walked on your ProForm Treadmill, first remove the key and unplug the power cord. Using the hex key, turn both rear roller bolts clockwise, 1/4 of a turn. When the walking belt is correctly tightened, you should be able to lift each side of the walking belt 2 to 3 inches off the walking platform. Keep the walking belt centered. Then, plug in the power cord, insert the key, and carefully walk on the treadmill for a few minutes. Repeat until the walking belt is properly tightened.
