Tensioning the Running Belt

For more information and/or how-to videos, visit our Customer Support section on our website. Contact information is located on the back page of the INFORMATION CARD.

WARNING

Running belt should NOT be moving during tensioning. Over-tightening the running belt can cause excessive wear on the treadmill as well as its components. Never over-tighten the belt.

 

If you can feel a slipping sensation when running on the treadmill, the running belt must be tightened. In most cases, the belt has stretched from use, causing the belt to slip. This is a normal and common adjustment. To eliminate this slipping, turn the treadmill off and tension both the rear roller bolts using the supplied Allen wrench, turning them ¼ turn to the right (clockwise) as shown. Turn the treadmill on and check for slipping. Repeat if necessary, but never turn the roller bolts more than ¼ turn at a time. Belt is properly tensioned when the slipping sensation is gone.

Caution

Do not run belt faster than 1 mph while centering. Keep fingers, hair and clothing away from 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 the running belt is too far to the left side: Using the supplied Allen wrench and with the treadmill running at 1 mph turn the left adjustment bolt 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.
