SYMPTOM: The incline of the treadmill does not
change correctly
a. See HOW TO CHANGE CONSOLE SETTINGS on
page 21 to calibrate the incline system.
SYMPTOM: The walking belt slows when walked on
a. If an extension cord is needed, use only a 3-con-
ductor, 14-gauge (2 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 walk on
the treadmill for a few minutes. Repeat until the
walking 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, please see the front cover of this manual.
d. If the walking belt still slows when walked on,
please see the front cover of this manual.
SYMPTOM: The walking belt is off-center
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 walk on the tread-
mill for a few minutes. Repeat until the walking belt
is centered.
SYMPTOM: The walking belt slips when walked on
a. First, remove the key and UNPLUG THE POWER
CORD. Using the hex key, turn both idler roller
screws clockwise, 1/4 of a turn. When the walking
belt is correctly 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 walk on the treadmill for a
few minutes. Repeat until the walking belt is prop-
erly tightened.
