Locate the Reed Switch (89) and the Magnet (62) on the left side of the Pulley (71). 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 necessary, loosen the M4.2 x t3mm Tek Screw (3), move the Reed Switch slightly, and then retighten the Screw.

Reattach the Hood (not shown), and run the treadmill for a few minutes to check for a correct speed reading.

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 min-

utes. Repeat until the walking belt is properly tight- ened.
