Centering the Belt

After the treadmill has been installed and leveled, the belt must be checked to confirm proper tracking. First, plug the power cord into a suitable outlet. See the topic titled Electrical Requirements, which appears earlier in this section, for details. Then, turn the treadmill ON.

Stand on the siderails of the treadmill and straddle the belt. Press the START key and increase the speed to 4.0-mph (6.4 kph) using the SPEED UP ARROW key.

If the striding belt moves to the right, turn the right tension bolt

(D) a quarter-turn clockwise with provided quarter-inch Allen wrench, and then turn the left tension bolt a quarter-turn counter-clockwise (see figure). This sets the striding belt tracking back to the center of the roller.

If the striding belt moves to the left, turn the left tension bolt a quarter-turn clockwise and then turn the right tension bolt a quarter-turn counter-clockwise to start striding belt tracking back to the center of the roller.

Repeat adjustments until the striding belt appears centered. The belt should be centered on the roller with an equal distance on both sides from belt to roller. Allow the machine to continue running for several minutes to observe if the tracking remains stabilized.

NOTE: Do not exceed one full turn of the adjusting screws in either direction. If, after one full turn, the belt does not track properly, contact Customer Support Services. The phone numbers are listed in the beginning of this manual.
