SYMPTOM: The incline of the treadmill does not
change correctly
a.
Hold down the Stop button and the Speed increase
button, insert the key into the console, and then
release the Stop button and the Speed increase
button. Next, press the Stop button, and then
press the Incline increase or decrease button. The
treadmill will automatically rise to the maximum
incline level and then return to the minimum level.
This will recalibrate the incline system. If the incline
system does not begin calibrating, press the Stop
button again, and then press the Incline increase or
decrease button again. When the incline system is
calibrated, remove the key from the console.
SYMPTOM: The walking belt slows when walked on
a. Use only a surge suppressor that meets all of the
specifications described on page 16.
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 deteriorate
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 off-center or slips
when walked on
a. If the walking belt is off-center, 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 counterclock-
wise 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 treadmill for a few min-
utes. Repeat until the walking belt is centered.
