Checking the Alignment of the Running Belt
The belt is aligned at the factory before shipment. However, during shipment or by using the
treadmill on an uneven surface, the belt might move off center. Proper belt alignment is
important because it allows the belt to remain centered and assures smooth operation. Take the
following steps to check the alignment:
1. Insert the magnetic safety key (K) into the opening on the electronic console. Locate the
ON/OFF (I/O) switch at the front of the treadmill and turn ON (I) the treadmill.
2. Stand beside the treadmill and press QUICK START. The running belt starts automatically
after the display scrolls the message, “
Belt Starting 3, 2, 1,...

3. Continue standing next to the treadmill and press the SPEED ▲ key to maintain the running
belt at a speed of 3 miles per hour (5 kph).
