WARNING! Do not overtighten 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 cen-
tering. 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 provid-
ed, 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 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 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 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.
z Turning the hex key counter clockwise brings the rear
rollers and belt towards you.
