SYMPTOM: The incline of the treadmill does not
change correctly
a. Hold down the Stop button, insert the key into the
console, and then release the Stop 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 but-
ton 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 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
The edges of the walking belt should be aligned with
the belt alignment marks (see the drawing below) on
the foot rails. If necessary, follow the instructions below
to align the walking belt.
a. IMPORTANT: If the walking belt rubs against
the foot rails, the walking belt may become
damaged. 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 treadmill for a few minutes. Repeat
until the walking belt is centered.
