Belt Adjustment and Tension

WARNING! Do not overtighten rollers! This will cause premature roller bearing failure!

Belt adjustment and tension performs two functions: adjustment for tension and centering. Your new treadmill comes pre-adjusted from the factory for tension and centering. Please follow the procedures below if the belt shifts left or right or if the belt slips while walking:

WALKING BELT HAS SHIFTING TO THE LEFT (Diagram 1)

First, unplug the power cord from the surge protector. Using the hex key provided, turn the left rear roller adjustment bolt ¼ turn in the clockwise direction. Plug the power cord back into the surge protector and run the treadmill at 2.5 mph. You should see the belt start to correct itself, moving back towards the center. Repeat the above procedure until the walking belt is centered. It may be necessary to set walking belt tension once you have completed this procedure if the belt feels like it is slipping while walking. Refer to below to the “Walking Belt Slipping” instructions.

¼turn in the clockwise direction. Plug the power cord back into the surge protector and run the treadmill at 2.5 mph. You should see the belt start to correct itself, moving back towards the center. Repeat the above procedure until the walking belt is centered. It may be necessary to set walking belt tension once you have completed this procedure if the belt feels like it is slipping while walking. Refer to below to the “Walking Belt Slipping” instructions.

WALKING BELT IS SLIPPING DURING USE (Diagram 3)

First, unplug the power cord from the surge protector. Using the hex key provided, turn both left and right rear roller adjustment bolts the same distance, usually a ¼ turn in the clockwise direction. Plug the power cord back into the surge protector and run the treadmill at 2.5 mph. You should now walk on the belt to determine if the belt is still slipping. Repeat the above procedure until the walking belt is not slipping. The tension should be just tight enough not to slip.
