Walking Belt Tension
The walking belt tends to stretch slightly with use, thus it may
need to be tightened. If the walking belt is too loose, the belt
may stop during operation (running or walking).
DO NOT OVERTIGHTEN BELT. Too much tension on the belt
causes unnecessary friction and wears the belt, motor,
rollers and electronics. To make sure the belt tension is
correct, put three fingers under the edge of the stationary
walking belt. You should be able to lift the side of the belt
approximately 2-3 inches (5-7 centimeters).
To Tighten Belt
1. Use the hex key provided with the treadmill. Place
the hex key in the hole in left end cap and into the
socket of the adjustment screw.
2. Turn key one full turn clockwise.
3. Place hex key in hole in right end cap and turn key
one full turn clockwise.
4. Check the tension of the belt.
5. Continue adjusting each side if the belt, back and
forth, until belt tension is correct.
6. Make sure to adjust both sides equally to keep the
belt correctly aligned.
Walking Belt Centering
The walking belt may need to occasionally be centered.
First, check the belt tension. It must be correctly adjusted.
Run the treadmill at about 3.5 mph (6km/h). Place the hex key
through the hole in the left end cap and into the socket of the
adjustment screw.
If Belt Moves to the Right
1. Turn the right adjustment screw 1/2 turn clockwise,
then turn the left adjustment screw 1/2 turn
counterclockwise.
2. If belt does not move, repeat until belt is centered.
3. Recheck the tension of the belt (see above).
If Belt Moves to the Left
1. Turn the right adjustment screw 1/2 turn
counterclockwise, then turn the left adjustment
screw 1/2 turn clockwise.
2. If belt does not move, repeat until belt is centered.
3. Recheck the tension of the belt (see above).
