SYMPTOM: The walking belt is off-center or slips when walked on

a.If the walking belt is off-center, first remove the key and UNPLUG THE POWER CORD. If the walking belt has shifted to the left, use the hex key to turn the left idler roller screw clockwise 1/2 of a turn; if the walking belt has shifted to the right, turn the left idler roller screw counterclock- wise 1/2 of a turn. Be careful not to overtighten the walking belt. Then, plug in the power cord, insert the key, and run the treadmill for a few minutes. Repeat until the walking belt is centered.

b.If the walking belt slips when walked on, first re- move the key and UNPLUG THE POWER CORD. Using the hex key, turn both idler roller screws clockwise, 1/4 of a turn. When the walking belt is correctly tightened, you should be able to lift each edge of the walking belt 2 to 3 in. (5 to 7 cm) off the walking platform. Be careful to keep the walk- ing belt centered. Then, plug in the power cord, in- sert the key, and carefully walk on the treadmill for a few minutes. Repeat until the walking belt is properly tightened.
