Remove the three M4.2 x 19mm Hood Screws (12)
and carefully pivot the Hood (67) off.
Locate the Reed Switch (70) and the Magnet (51)
on the left side of the Pulley (53). 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 M4.2 x 19mm Screw (1), move the
Reed Switch slightly, and then retighten the Screw.
Reattach the Motor Hood (not shown) with the
three M4.2 x 19mm Hood Screws (not shown) and
the two Screws (not shown) if necessary. Run the
treadmill 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 13.
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
idler 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.
c. If the walking belt still slows when walked on, see the front cover of this manual.
