Lower the treadmill (see HOW TO LOWER THE
TREADMILL FOR USE on page 27). Remove the
three #8 x 3/4" Screws (1). Carefully pivot the
Motor Hood (71) off.
Locate the Reed Switch (52) and the Magnet (50)
on the left side of the Pulley (49). 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 #8 x 3/4" Tek Screw (13),
move the Reed Switch slightly, and then retighten
the Screw. Reattach the Motor Hood (not shown)
with the five #8 x 3/4" Screws (not shown) and run
the treadmill for a few minutes to check for a cor-
rect speed reading.

SYMPTOM: The walking belt slows when walked on
a. Use only a single-outlet surge suppressor that
meets all of the specifications described on page
14.
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 screws 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.

c. Your treadmill features a walking belt coated with
high-performance lubricant. IMPORTANT: Never
apply silicone spray or other substances to the
walking belt or the walking platform unless in-
structed to do so by an authorized service rep-
resentative. Such substances may deteriorate
the walking belt and cause excessive wear. If
you suspect that the walking belt needs more lubri-
cant, see the front cover of this manual.
d. If the walking belt still slows when walked on, see
the front cover of this manual.
