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 treadmill 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 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 com-
pleted 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 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 pro-
vided, 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.
! 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 from
you.
