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 proce-
dures 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 provid-
ed, turn the left rear roller adjustment bolt ¼ turn in the clockwise direc-
tion. 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 ten-
sion 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 cor-
rect itself, moving back towards the center. Repeat the above proce-
dure 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 pro-
cedure 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.
