PROBLEM: The walking belt is off-center or slips when walked on
SOLUTION: a. If the walking belt is off-center, first remove the
k
ey and UNPLUG THE POWER CORD. If the
walking belt has shifted to the left, use the hex
k
ey to turn the left idler roller bolt clockwise 1/2 of a
turn; if the walking belt has shifted to the right,
turn the left idler roller bolt counterclockwise 1/2 of
a turn. Be careful not to overtighten the walking
belt. Then, 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 re-
move the key and UNPLUG THE POWER CORD.
Using the hex key, turn both idler roller bolts clock-
wise, 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 2 to 3 in. (5 to 7 cm) off
the walking platform. Be careful to keep the walk-
ing belt centered. Then, plug in the power cord, in-
sert the key, and carefully walk on the treadmill for
a few minutes. Repeat until the walking belt is
properly tightened.
