b. Remove the three 3/4" Screws (12) and carefully

pivot the Hood (61) off.

Locate the Reed Switch (71) and the Magnet (50)
on the left side of the Pulley (51). 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 nec-
essary, loosen the 3/4" Reed Switch Screw (15),
move the Reed Switch slightly, and then retighten
the Screw. Reattach the Hood (not shown) with the
#8 x 2" Screws (not shown) and the 3/4" Screws

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 13.

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 walk-
ing belt is properly tightened.
