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 9.
b. If the walking belt is overtightened, treadmill perfor-
mance may decrease and the walking belt may be per-
manently damaged. Remove the key and
UNPLUG
THE POWER CORD. Using the included allen wrench,
turn both rear roller adjustment bolts counterclockwise
1/4 of a turn. When the walking belt is properly tight-
ened, you should be able to lift each
edge of the walk-
ing 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 run the treadmill for a few min-
utes. 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, first remove the key and
UNPLUG THE POWER CORD. If the walking belt has
shifted to the left, use the allen wrench to turn the left
rear roller adjustment bolt clockwise 1/2 of a turn;
if the
walking belt has shifted to the right, turn the bolt
counterclockwise 1/2 of a turn. Be careful not to over-
tighten 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
allen wrench, turn both rear roller adjustment bolts
clockwise 1/4 of a turn. When the walking belt is cor-
rectly tightened, you should be able to lift each edge 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 walk on the treadmill for
a few minutes. Repeat until the walking belt is properly
tightened.
