PROBLEM: The walking belt slows when walked on
SOLUTION: a. Use only a single-outlet surge suppressor that meets all of the specifications described on page 13.
b. If the walking belt is overtightened, treadmill perfor-
mance may decrease and the walking belt may be-
come damaged. Remove the key and
UNPLUG THE
POWER CORD. Using the hex key, turn both rear
roller adjustment bolts counterclockwise, 1/4 of a turn.
When the walking belt is properly tightened, you
should be able to lift each side of the walking belt 3 to
4 inches off the walking platform. Be careful to keep
the walking belt centered. Plug in the power cord, in-
sert the key, and run the treadmill for a few minutes.
Repeat until the walking belt is properly tightened.
c. If the walking belt still slows when walked on, see the front cover of this manual.
PROBLEM: The walking belt is off-center or slips when walked on
SOLUTION: a. If the walking belt is off-center, 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 rear roller bolt clockwise 1/2 of a turn;
if the walk-
ing belt has shifted to the right, turn the left rear
roller bolt counterclockwise 1/2 of a turn. Be careful
not to overtighten the walking belt. Plug in the power
cord, insert the key, and run the treadmill for a few
minutes. Repeat until the walking belt is centered.
b. If the walking belt slips when walked on, first remove
the key and UNPLUG THE POWER CORD. Using
the hex key, turn both rear roller bolts clockwise, 1/4
of a turn. When the walking belt is correctly tightened,
you should be able to lift each side of the walking belt
3 to 4 inches off the walking platform. Be careful to
keep the walking belt centered. Plug in the power
cord, insert the key, and carefully walk on the tread-
mill for a few minutes. Repeat until the walking belt is
properly tightened.
PROBLEM: The incline of the treadmill does not change correctly
SOLUTION: a. With the key in the console, press one of the Incline buttons. While the incline is changing, re-
move the key. After a few seconds, re-insert the key. The treadmill will automatically rise to the
maximum incline level and then return to the minimum level. This will recalibrate the incline sys-
tem.
