How to Fix a Loose Treadmill Running Belt

Issue: Running belt is loose, drifting or slipping.

Resolution: This issue can be resolved by aligning/centering and tensioning the running belt.

Take caution when centering the belt. Do not run belt faster than 1 mph and keep fingers, hair and clothing away from the belt at all times.

If the running belt is too far to the right side: Using the supplied Allen wrench and with the treadmill running at 1 mph, turn the LEFT adjustment bolt counter-clockwise a ¼ turn and wait for the belt to adjust itself. Use the motor cover marking or part line as a reference for alignment. Repeat, if necessary, until the belt remains centered during use.

If you find the belt is slipping because it is too loose, center it, then tension as needed. For easier adjustment bolt access, remove the end caps.
