WARNING! Do not over-tighten rollers! This will cause prema-
ture 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 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 pro-
cedure until the walking belt is centered. It may be necessary to set walk-
ing 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 direc-
tion. 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 proce-
dure until the walking belt is centered. It may be necessary to set walk-
ing 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 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.
