SYMPTOM: The incline of the treadmill does not
change correctly
a. Calibrate the incline system of the treadmill (see
step 4 on page 30). 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
speci
fi
cations described on page 20.
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.

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
