WARNING! Do not over-tighten rollers! This will cause premature
roller bearing failure!
Belt adjustment and tension performs two functions: adjustment for ten-
sion and centering. Your new treadmill comes pre-adjusted from the facto-
ry 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 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 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.
