Belt Adjustment
WARNING! Do not over-tighten rollers! This will cause premature roller bearing failure!
Belt adjustment and tension performs two functions: adjustment for tension and centering. Your new tread-
mill comes pre-adjusted from the factory for tension and centering. Please follow the procedures below if
the belt shifts to the left or right while walking:
WALKING BELT IS SHIFTING TO THE LEFT
(Diagram 1)
First, turn treadmill on to run at 1 mph. Using the hex key provided, turn the left rear roller adjustment bolt
¼ turn in the clockwise direction. Next, run the treadmill at 2.5 mph. You should see the belt start to correct
itself by moving back toward 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 below to the “Walking Belt Slipping” instructions.
WALKING BELT IS SHIFTING TO THE RIGHT
(Diagram 2)
First, turn the treadmill on to run at 1 mph. Using the hex key provided, turn the right rear roller adjustment
bolt ¼ turn in the clockwise direction. Next, run the treadmill at 2.5 mph. You should see the belt start to
correct itself, moving back toward 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 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.
Note: Turning the hex key clockwise brings the rear rollers and belt towards you.
Turning the hex key counter clockwise pushes the rear roller and belt away from you.
