WARNING! Do not over-tighten rollers! This will cause pre-
mature 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 provided,
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 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 pro-
vided, turn the right rear roller adjustment bolt ¼ turn in the clock-
wise 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 neces-
sary to set walking belt tension once you have completed this proce-
dure 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 slip-
ping. 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.
