Next, locate the
Reed Switch
(104) and the
Magnet (102)
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" Truss Head Screw (14), move
the Reed Switch slightly, and then retighten the
Truss Head Screw. Reattach the Motor Hood (not
shown), and run the treadmill for a few minutes to
check for a correct speed reading.
SYMPTOM: The walking belt slows when walked on
a. If an extension cord is needed, use only a 3-conduc-
tor, 14-gauge (1 mm
2
) cord that is no longer than 5
ft. (1.5 m).
b. If the walking belt is overtightened, treadmill per-
formance may decrease and the walking belt may
become 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
instructed to do so by an authorized service
representative. Such substances may deterio-
rate the walking belt and cause excessive wear.
If you suspect that the walking belt needs more
lubricant, see the front cover of this manual.
d. If the walking belt still slows when walked on, see
the front cover of this manual.
SYMPTOM: The walking belt is not centered
between the foot rails. IMPORTANT: If the walking
belt rubs against the foot rails, the walking belt
may become damaged.
a. First, remove the key and UNPLUG THE POWER
CORD. If the walking belt has shifted to the left,
use the hex key to turn the left idler roller screw
clockwise 1/2 of a turn; if the walking belt has
shifted to the right, turn the left idler roller screw
counterclockwise 1/2 of a turn. Be careful not to
overtighten the walking belt. Then, plug in the
power cord, insert the key, and run the treadmill
for a few minutes. Repeat until the walking belt is
centered.
