Page 22

Remove the key from the console and UNPLUG THE POWER CORD. Remove the three #8 x 3/4" Screws (12) and carefully pivot the Hood (57) off.

Locate the Reed Switch (64) and the Magnet (42) on the left side of the Pulley (43). Turn the Pulley until the Magnet is aligned with the Reed Switch.

Make sure that the gap between the Magnet and the Reed Switch is about 1/8 in. (3 mm). If neces- sary, loosen the Reed Switch Screw (12), move the Reed Switch slightly, and then retighten the Screw. Reattach the Hood (not shown), and run the tread- mill for a few minutes to check for a correct speed reading.

PROBLEM: The incline of the treadmill does not change correctly

SOLUTION: a. With the key in the console, press one of the Incline buttons. While the incline is changing, re- move the key. After a few seconds, re-insert the key. The treadmill will automatically rise to the maximum incline level and then return to the minimum level. This will recalibrate the incline system.

PROBLEM: The walking belt slows when walked on

SOLUTION: a. Use only a single-outlet surge suppressor that meets all of the specifications described on page 11.

b. If the walking belt is overtightened, treadmill perfor- mance may decrease and the walking belt may be- come damaged. Remove the key and UNPLUG THE POWER CORD. Using the hex key, turn both rear roller bolts counterclockwise, 1/4 of a turn. When the walking belt is properly 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 walking belt centered. Then, plug in the power cord, insert the key, and run the treadmill for a few minutes. Repeat until the walking belt is properly tightened.
