Belt Adjustment and Tension
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
procedures below if the belt shifts left or right or if the belt slips while walking:
WALKING BELT HAS SHIFTING TO THE LEFT (Diagram 1)
First, unplug the power cord from the surge protector. Using the hex key provided, turn the left
rear roller adjustment bolt 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 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 to below to the “Walking Belt Slipping” instructions.
WALKING BELT HAS SHIFTING TO THE RIGHT (Diagram
2)
First, unplug the power cord from the surge protector. Using
the hex key provided, turn the right rear roller adjustment bolt
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 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 to 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.
