WARNING! Do not over-tighten rollers! This will cause premature
roller bearing failure!
Belt adjustment and tension performs two functions: adjust-
ment for tension and centering. Your new treadmill comes pre-
adjusted from the factory for tension and centering. Please fol-
low 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 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 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 provid-
ed, 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 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 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 dis-
tance, 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.
Turning the hex key counter clockwise brings the rear rollers and
belt towards you.
Turning the hex key clockwise pushes the rear roller and belt
away form you.
